4 [Source: CCP.II-RADIO ] Agenda Item 1.1: to consider an allocation of the frequency band MHz to the amateur service in Region 1, in accordance with Resolution 658 (WRC-15) Background The MHz frequency band is currently allocated to the amateur service on a primary basis in Regions 2 and 3. In Region 1, the band is currently allocated to only the Broadcasting Service on a primary basis. However, No of the Radio Regulations provides for an alternate allocation to the amateur service on a primary basis to a number of countries in Region 1, and No provides an alternate fixed and mobile, except aeronautical mobile, allocation on a primary basis to a number of countries in Region 1. WRC-15 decided to study the sharing between the amateur service and incumbent services in Region 1 towards a primary allocation that would facilitate further worldwide harmonisation and international operability. The opportunity provided by Agenda Item 1.1 to achieve global harmonisation would provide the means to introduce new and innovative systems, as well as harmonizing existing amateur service usage in the range MHz. The frequency range MHz marks the transition area between ionospheric and non-ionospheric propagation modes, which makes it particularly interesting for experimentation and study within the amateur service. The technical and operational characteristics of systems used in the amateur service for the purpose of performing sharing studies can be found in ITU-R Recommendation M Radio amateurs utilise allocations to the amateur service to engage in scientific and technical investigation and experimentation, provide communication in the wake of natural disasters, provide noncommercial public service communications, and conduct other activities to advance technical education, develop radio operating technique, and enhance international goodwill. [Source: CCP.II-RADIO/doc. 4444/17] The radiocommunication systems that operate amateur and amateur satellite services have open communication systems, through which messages are transmitted to different geographical regions for experimentation. Radio amateurs foster a source of experience in the exploration of propagation phenomena and the development of technologies for the efficient use of the radio spectrum and provide an opportunity for learning for all regardless of their location and/or social status. In addition to this, it is vital to consider and recognize the technical contributions made to telecommunications and the valuable support provided in cases of natural disasters, which also fulfill a social mission by being used to establish emergency communications. On this regard, the users of the different frequency bands that have allocation to the Amateur and Amateur Satellite Services, particularly in the frequency band MHz, must comply with the CCPII _i

5 provisions of the Radio Regulations in force, as well as international or regional agreements and the national regulations that apply to them. [Source: CCP.II-RADIO/doc. 4413/17] The band is also considered to provide the transition between propagation conditions existing in higher HF frequency bands and VHF spectrum. This situation provides valuable experience in F2, Sporadic E and Meteor Scatter propagation. Paths across northeast and southeast Brazil are usual, as well from south Brazil to the Caribbean region by Transequatorial propagation. Beacons are installed in the first portion of the band to serve as propagation indicators. Furthermore in recent years additional propagation studies have been made possible through the granting of all or parts of the frequency band MHz to the amateur service in a number of Region 1 countries. As a result Brazilian amateur licensees have been able to communicate with Region 1 licensees when propagation conditions permit. These characteristics and the use of the band fulfill the objective of the service as defined in article 1.56 of the Radio Regulations and engage the practitioners in scientific and technical investigations, as well as helping to develop radio operating techniques also useful for emergency communications. PRELIMINARY VIEWS: USA, CAN, B WRC-19 Agenda Item 1.1 is a Region 1 issue. Any changes made to the Radio Regulations under WRC- 19 Agenda Item 1.1 must not impact the existing allocation to the amateur service in MHz in Region 2, nor subject Region 2 to any changed procedural or regulatory provisions. [Source: CCP.II-RADIO/doc. 4444/17] MEX WRC-19 agenda item 1.1 is a Region 1 issue, that if adopted, it could facilitate global harmonization of the MHz frequency band for the amateur service. However, any changes made to the Radio Regulations under WRC-19 agenda item 1.1 must not impact the existing allocation to the amateur service in MHz in Region 2, nor subject Region 2 to any changed procedural or regulatory provisions in force.

7 Agenda item 1.2: to consider in-band power limits for earth stations operating in the mobile-satellite service, meteorological-satellite service and Earth exploration-satellite service in the frequency bands MHz and MHz, in accordance with Resolution 765 (WRC-15) Resolution 765 (WRC-15) Establishment of in-band power limits for earth stations operating in mobile-satellite service, the meteorological-satellite service and the Earth exploration-satellite service in the frequency bands MHz and MHz, calls for the necessary technical, operational and regulatory consideration of the possibility of establishing in-band power limits for earth stations in the EESS and MetSat services in the frequency bands MHz and in the MSS frequency band MHz. BACKGROUND The bands MHz and MHz are used for uplink transmission by the Data Collection System (DCS) under the EESS, MetSat and MSS allocations. The DCS is a network of sensors measuring temperature, pressure, humidity, sea level, and tracking animal migration, located in areas difficult to reach. These measurements indispensable for monitoring and predicting climate change; monitoring oceans, weather, and water resources. Additionally, these systems assist in protecting biodiversity, and improve maritime safety, and security. The data is transmitted to GSO and non-gso satellite networks using the non-gso MSS allocation in the band MHz or the meteorological satellite allocation in the band MHz. These systems usually operate most efficiently together by using moderate to low equivalent isotropically radiated power (e.i.r.p.) levels, resulting in small link margins. These frequency bands are also used by non-geostationary satellites for telecommand space operation purposes functions under the EESS, MetSat service, or MSS allocations and a growing number of these satellites are planned. The output power levels of the earth stations at the antenna portpeak e.i.r.p. of these telecommand links (Earth-to-space) can be much higher than the moderate to low power levelsthose used for the DCS service links, leading to potential harmful interference to DCS satellite receivers. Recommendation ITU-R SA.2045 provides information on the performance and interference criteria for relevant geostationary-satellite orbit (GSO) and non-geostationary satellite (non-gso) DCS in the frequency band MHz. Recommendation ITU-R SA.2044 provides information on the current and future usage of non-gso DCS in the frequency band MHz, and the portioning of the frequency band to allow all DCS equal access to the spectrum. Recommendation ITU-R M.2046 provides a description, and the corresponding protection criteria for broadband noise and narrowband interference, of one MSS system that uses the frequency band MHz (Earth-to-space). ISSUES The bands MHz and MHz are used by the data collection system (DCS) for transmitting information from low-power sensors to satellites. A growing number of non-geostationary satellites systems are currently using or planned to use these frequency bands for space operation functionstelecommand, which uses can be much higher than those used for the DCS service linkssensors. The agenda item considers implementing uplink power limits to protect DCS operations, but that could limit the use of these bands for space operation telecommand applications. CCPII _i

8 It is necessary to have stable regulatory certainty in order to be able to provide long-term continuity for the operation of data collection systems (DCS). DCS represents long-term efforts and significant investments. The establishment of in-band power limits for earth stations operating in the EESS, MetSat service, and MSS would bring confidence for DCS operators using the frequency bands MHz and MHz. PRELIMINARY VIEW: Canada Canada is of the view that within the range MHz, 20 khz of spectrum should be exempt from any e.i.r.p. limits in order to allow space operation functions to continue in the band, while providing protection and regulatory certainty for the operation of DCS. Locating the band exempt from e.i.r.p. limits at the edge of the MHz range would limit the impact to DCS. In the MHz range, Canada is the of the view that sharing between non-geostationary satellite systems using space operation functions and GSO DCS may be feasible using mitigation techniques such as GSO arc avoidance and the use of directional antennas. Implementing for example e.i.r.p. density limits for earth stations in the MHz band would provide flexibility for non-gso space operation functions to operate while protecting GSO DCS receivers. Canada is also of the view that any new limits should only apply to systems that have not been brought into use by the end of WRC-19. USA USA supports conducting and completing the necessary technical, operational, and regulatory studies on the possibility of establishing in-band power limits for earth stations in the EESS and MetSat service in the frequency band MHz and the MSS in the frequency band MHz.

10 Agenda item 1.3: to consider possible upgrading of the secondary allocation to the meteorologicalsatellite service (space-to-earth) to primary status and a possible primary allocation to the Earth exploration-satellite service (space-to-earth) in the frequency band MHz, in accordance with Resolution 766 (WRC-15) BACKGROUND The meteorological-satellite service is used by the data collection system (DCS). The DCS is a network of sensors measuring temperature, pressure, humidity, sea level, tracking animal migration and sailboats, located in areas difficult to reach. The data is transmitted to GSO and non-gso satellite networks. Most DCS are using the band MHz for data downlinks to transmit the information collected by the DCS sensors. The MHz band is allocated on a primary basis to the fixed and mobile services, It is also allocated on a secondary basis to the meteorological-satellite service in the space-to-earth direction, upgraded to primary allocation in a few countries of Regions 1 and 3 per No The operation of EESS applications is also permitted via RR No on a no-interference, no-protection basis. Under the co-primary allocation to the mobile service, the frequency band MHz is identified for use by administrations wishing to implement International Mobile Telecommunications (IMT) in all 3 Regions pursuant to Radio Regulation No 5.286AA. Additionally, channels in the range MHz can be used for maritime on-board communications as per No and No In order to provide regulatory certainty, MetSat and EESS stakeholders are seeking to upgrade the meteorological-satellite allocation to primary status and to include a primary EESS allocation in the band MHz while providing protection and not imposing additional constraints on existing primary services. This would bring confidence for administrations and space agencies involved in DCS and for the public sector funding the development and operation of such systems. In order to protect systems of the terrestrial service, the United States have already adopted a pfd limit imposed on space stations. Within this band, the Argos Data Collection System (ADCS) monitors more than 21,000 active Argos platforms collecting data for over 2,000 distinct projects in 100+ countries. Critical applications of the ADCS include atmospheric and ocean monitoring/research, tropical cyclone forecasting, fishery management, oil spill tracking, fishing vessel tracking, search and rescue modeling (at sea), anti-piracy alerting, import/export and hazardous materials tracking, endangered species studies, migration mapping, and wildlife tracking and management. The administration of the Argos program is under a joint agreement between the National Oceanic and Atmospheric Administration (NOAA) and the French Space Agency, Centre National d Etudes Spatiales (CNES). Additional partners include the European Organization for the Exploitation of Meteorological Satellites (EUMETSAT), and the Indian Space Research Organization (ISRO). The meteorological-satellite (space-to-earth) service operates on a secondary basis to the fixed and mobile services and thus it must not interfere with these services. Critical applications of licensees using this spectrum include Public Safety dispatch of first responders; correctional institution communications; state and local government operation and homeland security response; critical infrastructure communications (water, sewer, power and fuel pipeline control); and hospital operations. In addition, the MHz band is used by alarm service providers to monitor homes, businesses and government facilities in several countries within and outside the region to detect fires, medical emergencies, home CCPII _i

11 invasions and other urgent circumstances, and alert first responders 1 To protect the fixed and land mobile services within one Administration, a power flux density (pfd) limit of -152 dbw/m 2 /4kHz has been imposed on the meteorological-satellite (space-to-earth) service. One administration has conducted preliminary testing which shown that, at satellite angles of arrival below 25 degrees, the -152 dbw/m 2 /4kHz limit is not adequate to protect terrestrial operations. To provide the necessary protection to existing services in the band, globally, the next generation of ADCS transmitters would have to implement direct sequence spread spectrum or equivalent technology in the satellite downlink to reduce the pfd in the MHz band to less than -152 dbw/m 2 /4kHz, or such other levels determined necessary to protect terrestrial operations, depending on the angle of arrival. With respect to a potential new primary EESS allocation,, such an allocation would bring confidence to the space agencies involved in Satellite Data Collection Programs and would ease coordination with other Administrations. These space programs do represent a long-term effort and require decades of investment between the time the program is officially approved and the time the various satellites are in operation, keeping in mind that usually many satellites are deployed in order to provide a continuous service. For the specific case of this band, the number of satellites expected to be in operation is limited for cost reasons, and it is unlikely that two satellites will transmit at the same time over the same geographical area. ISSUES An upgrade of the Metsat and EESS allocation to primary status would provide regulatory certainty for data collection systems. Measures need to be taken to ensure protection of and that no constraints are put on, fixed and mobile services, including the use of the band for IMT. PRELIMINARY VIEW: ARGENTINE REPUBLIC The Argentine Republic supports the conduction of studies related to item 1.3 of the WRC-19 Agenda. However, it points out the importance of determining a proper pdf limit to be imposed to MetSat (spaceto-earth) and EESS (space-to-earth) to protect the existing primary services to which this frequency band is already allocated. The change of status of the allocation to these services from secondary to primary must not produce interferences in the provision of the mobile service that already has a primary status, and is identified for use by the IMT systems (see Note 5.286AA of the Radio Regulations) in the three regions of ITU. In the Argentine Republic the feasibility of allocating the Mobile Service and identifying for use by the Advanced Mobile Communication Systems (SCMA) the band of MHz is currently under study, taking into consideration for this the frequency arrangements currently under elaboration at the ITU-R Working Group 5D, specifically the provisions to be included in the new version (under elaboration) of Recommendation ITU-R M.1036 Frequency arrangements for the implementation of terrestrial component of International Mobile Telecommunication (IMT) in the bands identified for IMT in the Radio Regulations (RR). 1 Alarm radio systems operate in the MHz band in more than 50 nations outside of the United States, including countries such as Canada, Greece, Ireland, Russia, Spain, United Kingdom, Netherlands, Columbia, France, Belgium, Bolivia, Saudi Arabia, Mexico, Ethiopia, Argentina, Brazil and Cambodia. CCPII _i

12 USA The United States supports conducting and completing sharing and compatibility studies with the coprimary fixed and mobile services, including IMT systems. These studies would determine the feasibility of potentially upgrading the MetSat (space-to-earth) allocation to primary status, and the potential addition of a primary EESS (space-to-earth) allocation in the frequency band MHz, while protecting the current primary allocations for fixed and land mobile services including IMT systems and maintaining the conditions contained in No Should studies support the upgrade of the MetSat service and/or addition of a primary allocation to the EESS, the appropriate pfd limit should be determined for MetSat (space-to-earth) and EESS (space-to- Earth) systems to protect the existing and planned deployments of primary services in the frequency band MHz. Should studies conclude that a less restrictive pfd limit than that contained in Resolution 766 (WRC-15) considering further a) can protect incumbent services, then the pfd limit ( 152 dbw/m 2 /4 khz) shall apply. To the extent that sharing and compatibility studies, field tests and other relevant input indicate that a more restrictive pfd limit is necessary to protect terrestrial operations, this more restrictive limit must be adopted if any upgrade to the existing MetSat secondary allocation or new allocation to EESS is proposed.

14 Agenda Item 1.4: to consider the results of studies in accordance with Resolution 557 (WRC-15), and review, and revise if necessary, the limitations mentioned in Annex 7 to Appendix 30 (Rev.WRC-12), while ensuring the protection of, and without imposing additional constraints on, assignments in the Plan and the List and the future development of the broadcasting-satellite service within the Plan, and existing and planned fixed-satellite service networks; BACKGROUND: Appendix 30 contains provisions for use of the broadcasting-satellite service (BSS) Plans and Regions 1 and 3 List, as well as for modifying the Plan (in the case of Region 2) or the List (in the case of Regions 1 and 3). It is a self-contained Appendix, including provisions for modifying the Plan or List (Article 4), notifying Plan or List assignments (Article 5) and for coordinating other services in the frequency bands vis-a-vis the Plan and List (Articles 6 and 7). Appendix 30 also contains detailed criteria for sharing between the Plan/List and other services. Specifically, Annex 1 to Appendix 30 provides criteria for determining whether the assignments of an administration are affected by a proposed modification to the Region 2 Plan or by a proposed new or modified assignment in the Regions 1 and 3 List; Annex 4 to Appendix 30 provides criteria to determine the need to coordinate the fixed-satellite service (FSS) (or BSS not subject to a Plan) with the assignments of the Plans; and finally Annex 7 to Appendix 30 contains orbital position limitations on modifications to the BSS Plan or List. The Ku-band frequencies are not globally harmonized; so, for example, the range GHz is BSS in Region 1 and FSS in Region 2, the range GHz is FSS in Region 1 and BSS in Region 2, and the range GHz is BSS in both Regions 1 and 2. The Annex 7 orbital position limitations on modifications to the BSS Plan or List were designed to facilitate BSS sharing with the FSS in the shared part of the orbital arc between Regions 1 and 2, and are specifically applicable to Region 2 BSS in GHz and to Region 1 BSS in GHz. The Annex 7 orbital position limitations were maintained at WRC-2000 (the most recent BSS Planning conference, which focused on Regions 1 and 3) for the reason that during a Planning conference, many new BSS slots could be adopted at once, which could significantly limit the future access of FSS to the shared portion of the orbital arc. Some of the criteria of Annex 1 and Annex 4 to Appendix 30 were updated at WRC Since then there has been considerable experience in working with the Plans and the criteria of Annexes 1 and 4 to Appendix 30. On-going ITU R studies reported that the provisions for Region 1 BSS in Annex 7 to Appendix 30 may no longer be required, and in consequence WRC-15 adopted Agenda Item 1.4 to consider the results of studies in accordance with Resolution 557 (WRC-15) to review the limitations mentioned in Annex 7 to Appendix 30 and see if they could be removed or modified to provide additional access to this valuable spectrum resource. It is envisioned that studies will assess each portion of the orbital position limitations in Annex 7 (including, e.g., the orbital positions in Section A2 applicable to Region 2 BSS) to determine whether each could individually be removed or modified. CCPII _i

15 Preliminary View: CAN, MEX, USA With respect to Agenda Item 1.4, these Administrations United States and Canada support the studies in accordance with Resolution 557 (WRC-15). Based upon successful conclusion and feasibility of these activities, these Administrations United States and Canada support the review and revision, as necessary, of the limitations of Annex 7 to Appendix 30 (Rev.WRC-12), while ensuring the protection of, and without imposing additional constraint on, existing assignments in the Plan and the List and the future development of BSS service within the Plan, and existing and planned fixed-satellite service networks.

17 Agenda Item 1.5: to consider the use of the frequency bands GHz (space-to-earth) and GHz (Earth-to-space) by earth stations in motion communicating with geostationary space stations in the fixed-satellite service and take appropriate action, in accordance with Resolution 158 (WRC-15); BACKGROUND: The topic of earth station in motion (ESIMs) communicating with geostationary (GSO) space stations in the fixed-satellite service (FSS) was addressed at WRC-15. Specifically, the Conference addressed ESIM operations in the frequency bands GHz (Earth-to-space) and GHz (space-to-earth) and adopted footnote No A and Resolution 156, which establish a framework for operation of ESIM globally with GSO FSS satellites in these bands. Recognizing the increasing need for communications on the move, including the availability of global broadband satellite services, WRC-15 adopted Agenda Item 1.5 for WRC-19 to consider the operation of ESIMs in the GHz (Earth-to-space) and GHz (space-to-earth) FSS frequency bands by GSO space stations. In addition to being adjacent to the frequency bands where FSS ESIM operations are allowed, GSO FSS satellites are operating in these bands. ESIMs serve a wide range of applications on-board aircraft and ships as well as on land and the number of users and data requirements are growing. ESIM-delivered services are key to government users and enterprise users in many sectors including maritime shipping, media and energy customers who often have to operate in remote parts of the world. The expectation of the user is to be able to be connected anywhere and broadband global satellite service is a key component on how to meet that need. As an example of how demand for ESIM type services is growing, the in-flight connectivity market is expected to reach USD 5.80 Billion by This market segment is geared toward providing air travelers enhanced on-demand entertainment options as well as allowing them to create a virtual office on the aircraft. Considering that the growing demand for broadband communications includes requirements for users on vessels, aircraft and vehicles at fixed locations and while in motion, Resolution 158 (WRC-15) invites ITU-R to study the technical and operational characteristics and user requirements of different types of earth stations in motion that operate or plan to operate within geostationary FSS allocations in the frequency bands GHz and GHz, or portions thereof. This includes the use of spectrum to provide the envisioned services to various types of earth station in motion and the degree to which flexible access to spectrum can facilitate sharing with other services allocated in these bands. The Resolution also calls for sharing and compatibility studies between earth stations in motion operating with geostationary FSS networks and current and planned stations of existing services allocated in the frequency bands GHz and GHz to ensure protection of, and not impose undue constraints on, services allocated in these frequency bands. ISSUES: The frequency bands GHz and GHz, or portions thereof, are allocated to the fixed and mobile services on a primary basis in Region 2. In the GHz range, some Region 2 administrations have widely deployed fixed services, consisting mostly of point-to-point applications in both urban and rural areas. In the GHz range, there are currently some fixed deployments by some Region 2 administrations, but rapid growth and wide-scale deployments of mobile systems deployments are expected/planned by some administrations in the GHz portion of the frequency band. CCPII _i

18 Considering the significant amount of existing and/or potential fixed and mobile system deployments in the frequency bands / GHz, sharing and compatibility studies between earth stations in motion operating with geostationary FSS networks and fixed and mobile service systems are being carried out to ensure protection of, and not impose undue constraints on the fixed and mobile services. These studies are also necessary to provide administrations with technical information related to sharing between these services (see recognizing further k of Resolution 158). It should be noted that resolution of technical issues related to assessing the impact of time-varying ESIMs interference on operation of non-geostationary satellite orbit (NGSO) MSS feeder links in the GHz (space-to-earth) and GHz (Earth-to-space) bands, and to developing appropriate methodologies to carry out such analysis, is essential to ensure protection of existing and planned services provided by such systems (See recognizing further g) and h) of Resolution 158). B, CAN, MEX Status of studies and work within the ITU-R Within ITU-R Working Party 4A (WP 4A), draft CPM text has been developed, with currently two methods to satisfy this agenda item: 1. NOC 2. New footnote in Article 5 of the Radio Regulations indicating that the operation of earth stations in motion communicating with the GSO FSS in the bands GHz and GHz is subject to the application of a new Resolution. Work within WP 4A continues on the development of a draft new Resolution, which currently has 3 Annexes, the first Annex outlining the provisions for ESIM to protect NGSO FSS, and NGSO MSS feeder links in the frequency band GHz, the second outlining provisions for ESIM to protect terrestrial services (fixed and mobile) in the frequency band GHz, and the third to provide Administrations with guidelines to assist administrations to authorize ESIM in the frequency band GHz. This third Annex is intended to clarify the responsibilities of the various entities involved in management of interference with regards to aeronautical, maritime and land-based ESIM. With respect to space services in the GHz and GHz bands, and with respect to satellite networks or systems of other administrations, it was agreed that ESIM operations shall remain within the envelope of the satellite network with which they communicate, which is reflected in the draft Resolution. Results of studies on sharing conditions for ESIM with terrestrial services in the GHz band concluded that there would be potential for interference from terrestrial service transmitters to ESIM receivers. The receiving ESIM shall therefore operate under the condition of not claiming protection from interference from terrestrial services operating in accordance with the Radio Regulations. In the frequency band GHz, ESIM will be transmitting and shall not cause unacceptable interference to any terrestrial services operating in accordance with the Radio Regulations. Portions of the GHz and GHz Ka-band are widely used by certain administrations in Region 2 for the provision of satellite communication services. Significant investments have been made to deploy satellite networks in these bands to deliver services in Region 2 and around the world. Ka-band is the most likely spectrum for operators to expand their existing satellite fleet as well as the spectrum where new comers to the satellite market will deploy their networks. Sharing and compatibility CCPII _i

19 studies between earth stations in motion operating with geostationary FSS networks, and current and planned stations of existing services allocated in the frequency bands GHz and GHz have been conducted to ensure protection of, and not impose undue constraints on, services allocated in these frequency bands. It should be noted that significant investments have also been made by the fixed service in portions of the band GHz in Region 2, while other such investments will be made by the fixed and mobile service in portions of the band GHz in some Administrations of Region 2. As such, studies have been conducted to ensure protection of, and not impose undue constraints on, these services allocated in these frequency bands. (See considering b) and recognizing further f) of Resolution 158). It should also be noted that resolution of technical issues related to assessing the impact of time-varying ESIMs interference on operation of non-geostationary satellite orbit (NGSO) FSS in the GHz (space-to-earth) and GHz (Earth-to-space) bands, and to developing appropriate methodologies to carry out such analysis are essential to ensure protection of existing and planned services provided by such systems. (See recognizing further f) of Resolution 158). PRELIMINARY VIEWS: CAN Canada supports the addition of a new footnote in Article 5 of the Radio Regulations to satisfy this agenda item. This footnote would subject ESIM use in frequency bands GHz and GHz to the application of a new Resolution containing specific conditions of operation for ESIM that ensures the protection of services in the bands, including FSS (both geostationary and non-geostationary satellite systems, and NGSO MSS feeder links) and terrestrial services (fixed and mobile). The Resolution would also contain guidelines to assist administrations to authorize ESIM in these bands. B, MEX, USA Support studies under the terms of Resolution 158 (WRC-15) on sharing and compatibility between ESIMs and current and planned stations of existing services allocated in the frequency bands GHz and GHz, while ensuring protection and not imposing undue constraints on these allocated services, and to take appropriate action based on the results of these studies. Before identifying use of the frequency bands, or portions thereof, for ESIM operation, studies should address each operational type of earth stations in motion to include the appropriate technical and regulatory provisions necessary to ensure protection of existing and planned allocated services. MEX Furthermore, bearing in mind that the present Agenda Item refers to ESIMs communicating with geostationary satellite systems, once the respective studies have been completed, if appropriate, studies for ESIMs communicating with non-geostationary satellite systems operating on the same frequency bands could also be considered.

21 Agenda item 1.6: to consider the development of a regulatory framework for non-gso FSS satellite systems that may operate in the frequency bands GHz (space-to-earth), GHZ (spaceto-earth), GHz (Earth-to-space) and GHz (Earth-to-space), in accordance with Resolution 159 (WRC-15) BACKGROUND Article 22 of the Radio Regulations contains provisions to ensure compatibility of non-gso FSS operations with GSO networks for the 14/11 GHz and 30/20 GHz bands. Among these provisions are uplink and downlink equivalent power flux density (epfd and epfd ) limits to protect GSO networks from unacceptable interference pursuant to RR No These measures contribute to provide a welldefined regulatory framework for non-gso systems operating in the 14/11 and 30/20 GHz frequency bands. There are currently no regulatory provisions for sharing between non-gso systems and GSO networks in the 50/40 GHz frequency bands. To address these issues, WRC-15 established agenda item 1.6 and associated Resolution 159 (WRC-15) for WRC-19: to consider the development of a regulatory framework for non-gso FSS satellite systems that may operate in the frequency bands GHz (space-to-earth), GHz (spaceto-earth), GHz (Earth-to-space) and GHz (Earth-to-space),in accordance with Resolution 159 (WRC-15) which invites the ITU-R membership to contribute to Studies of technical, operational issues and regulatory provisions for non-gso fixed-satellite services satellite systems in the frequency bands GHz (space-to-earth), GHz (space-to-earth), GHz (Earth-to-space) and GHz (Earth-to-space). Resolution 159 (WRC-15) discusses the development of new technologies in the Fixed Satellite Service (FSS) in frequency bands above 30 GHz that would allow for the provision of high-capacity and low-cost communications in all parts of the world, especially in remote and isolated areas. This Resolution considers that satellite constellations in both geostationary-satellite orbits (GSO) and non-geostationarysatellite orbits (NGSO) would allow for the implementation of these new technologies in the FSS bands and that the Radio Regulations should enable the introduction of such technologies to ensure efficient use of the radio spectrum. Resolution 159 (WRC-15) resolves to invite the ITU-R to conduct and complete in time for WRC-19 studies on the regulatory provisions to enable the operation of NGSO FSS satellite systems in the above mentioned frequency bands, including sharing studies with GSO, EESS, and RAS: Non-GSO FSS systems in the 50/40 GHz band could allow for the delivery of global broadband communications. Recent advances in satellite design, launch service capabilities and user terminal technology make it feasible to provide global satellite broadband services. Thanks to these recent technological advances, next-generation non-gso satellite systems are currently being developed. These systems can greatly enhance the efficient use of existing FSS spectrum by using next-generation satellite and earth station technology. The benefits of such non-gso satellite systems include providing worldwide connectivity and high-quality communication services to users in all geographic settings, be they urban, rural or remote, and offer tools for definitively addressing the longstanding digital divide. Developing a regulatory framework in the 50/40 GHz band will provide regulatory certainty to allow non-gso satellite systems to efficiently operate in these existing FSS frequency bands, while protecting GSO and other existing services. CCPII _i

22 ISSUES What are the appropriate limits and regulatory provisions to be adopted to ensure the protection of GSO FSS space and Earth stations? What is the appropriate regulatory approach to be adopted to address sharing between NGSO FSS space stations? Should Resolution 750 (Rev. WRC-15) be modified to include limits or recommended maximum levels for unwanted emissions to protect EESS (passive) in the bands GHz and GHz from the NGSO FSS system operating in the adjacent bands? What approach should be retained to ensure the protection of RAS stations in the frequency bands GHz, GHz and GHz from NGSO FSS operating in the adjacent bands? Preliminary results of studies on the protection of EESS (passive) systems in the GHz and GHz frequency bands Preliminary studies, in accordance with Resolution 159 (WRC-15) have been submitted to WP4A on the compatibility between non-gso FSS systems operating in the bands GHz (space-to- Earth), GHz (space-to-earth), GHz (Earth-to-space) and GHz (Earth-tospace). For the bands, GHz (space-to-earth), GHz (Earth-to-space) and GHz (Earth-to-space) studies were carried out between non-gso FSS systems and EESS (passive) systems operating in the frequency bands GHz and GHz. Studies were also undertaken for EESS (passive) systems operating in the GHz frequency band. A number of ITU-R Recommendations and Reports have been considered in these studies as they provide details on technical and operational characteristics of EESS (passive) sensors, bands of operation and protection criteria. In particular, ITU-R Recommendation RS.1861 and ITU-R Recommendation RS.2017 provide technical and operational characteristics of EESS (passive) services and interference criteria for satellite passive remote sensing in various bands, respectively. As well, Table 1-1 of Resolution 750 (REV.WRC-15) provides limits of unwanted emission power from active service stations in a specified bandwidth within the EESS (passive) band GHz. One study undertaken for EESS (passive) systems operating in the GHz frequency band has shown that the protection criteria for these systems are not exceeded for various deployment scenarios of LEO and MEO non-gso FSS systems. Several studies were undertaken to determine the impacts of service and gateway links for various LEO and MEO non-gso systems operating in the bands GHz and GHz on EESS (passive) systems operating in the GHz frequency band. These studies have shown that the protection criteria for the EESS (passive) systems are exceeded. Mitigation measures and / or revisions to the unwanted emission limits are necessary to limit the levels of unwanted emissions in the band GHz. More studies will be carried out within WP4A to better ascertain the sharing conditions for various types of non-gso FSS systems CCPII _i

23 Preliminary studies on compatibility between non-gso FSS and GSO FSS systems Studies have been submitted to WP4A on the compatibility between non-gso FSS and GSO FSS systems operating in the bands under consideration. Some of these studies study the impact of non-gso FSS systems on the time allowance for degradation (unavailability) of GSO FSS reference links. Simulations have shown that the increase in unavailability caused by individual non-gso FSS systems does not exceed 3%. In addition, the use of GSO arc avoidance significantly decreases the increases in unavailability due to interference caused by non-gso FSS systems. Therefore, GSO arc avoidance would be an effective mitigation technique in reducing the impact of interference from non-gso systems. These studies propose to stipulate a maximum value in the Radio Regulations for the increase in GSO unavailability that may be caused by one non-gso FSS system. This proposed solution would be independent of the non-gso FSS system simulated. Further, to ensure protection of these GSO FSS reference links from the aggregate emissions of all cofrequency non-gso FSS systems, regulatory provisions would also be needed to require administrations to determine the overall increase in link unavailability due to the aggregate interference levels from all non-gso FSS systems. This determination would be done with a set of GSO reference links defined for various geo-climactic regions in the world. These studies have demonstrated that the operation of non-gso systems does not exceed the protection requirements of GSO FSS networks stipulated in Recommendation ITU-R S Preliminary studies on compatibility between non-gso FSS systems A study on sharing conditions between non-gso FSS systems operating in the frequency bands GHz (space-to-earth) and GHz (limited to feeder links only), GHz and GHz (all Earth-to-space) was submitted to WP4A. This study examined the effectiveness of two mitigation techniques (orbital angle avoidance and earth station site diversity). The results of the study showed that modest avoidance angles and earth station site diversity were effective mitigation techniques, allowing for compatibility between the non-gso FSS systems studied. PRELIMINARY VIEW B/CAN/MEX/USA/ Administrations support studies under WRC-19 Agenda Item 1.6 regarding the development of a regulatory framework for non-gso satellite systems in the existing FSS allocations in the GHz (space-to-earth), GHz (space-to-earth), GHz (Earth-to-space) and GHz (Earth-to-space) frequency bands under the terms of Resolution 159 (WRC-15) and to take appropriate action based on the results of these studies. CAN For the protection of GSO systems, Canada supports the approach of determining the maximum singleentry and aggregate increase in GSO unavailability caused by non-gso systems. This method will require a set of GSO reference links for implementation. MEX As set forth in Resolution 159 (WRC-15), any regulatory framework that is developed must guarantee protection of geostationary satellite networks without limiting or unduly constraining the future development of geostationary networks across these bands. As a result, the Administration of Mexico CCPII _i

24 supports the current work being done in WP 4A focusing on establishing an appropriate and efficient methodology to facilitate the development of non-geostationary systems in these bands, as long as protection of existing and planned geostationary networks is guaranteed, without imposing any kind of technical or operational limitations to these geostationary networks. B/CAN/MEX For the band GHz: Administrations are of the view that based on the results of studies, EESS (passive) systems operating in the GHz band and non-gso FSS systems are compatible and no regulatory measures are required to address the compatibility between these two services. For the band GHz: Administrations are of the view that based on the results of studies, mitigation techniques and/or regulatory measures such as revising the current unwanted emission limits in Resolution 750 (WRC-15) are required to ensure compatibility between EESS (passive) systems operating in the band GHz and non-gso FSS systems. Administrations are of the view that the use of the bands GHz (space-to-earth), GHz (space-to-earth), GHz (Earth-to-space) and GHz (Earth-to-space) by non-gso FSS systems should be subject to coordination procedures under No B/MEX Formatted: Font: Bold Regarding resolves 4 and 5 of Resolution 159 (WRC-15), countries are of the view that changes to the FSS GSO limits in Resolution 750 (Rev. WRC-15) fall outside the scope of Agenda item 1.6. CCPII _i

25 31 MEETING OF PERMANENT CONSULTATIVE COMMITTEE II: RADIOCOMMUNICATIONS July 16 to 20, 2018 Guadalajara, Jalisco, Mexico OEA/Ser.L/XVII CCP.II-RADIO-31/doc /18 19 July 2018 Original: English PRELIMINARY VIEWS FOR WRC-19 AGENDA ITEM 1.7 (Item on the agenda: 3.1 (SGT2)) (Document submitted by the Rapporteur). SGT2B Science Services Coordinator: Glenn Feldhake (USA) Alternate Coordinator: Michael Razi (CAN) Rapporteur Agenda Item: Carlos Flores (USA) CCPII _i

26 Agenda item 1.7: to study the spectrum needs for telemetry, tracking and command in the space operation service for non-gso satellites with short duration missions, to assess the suitability of existing allocations to the space operation service and, if necessary, to consider new allocations, in accordance with Resolution 659 (WRC-15) BACKGROUND Satellites for short duration missions are used for a wide range of applications, including Earth observation, space research and mobile-satellite communication. The demand for suitable spectrum for NGSO satellites with short duration missions is growing due to the increasing number of these types of satellite missions. The mass, dimensions and low cost of these satellites contribute to their success and their use will likely grow. These types of missions provide an affordable means for scientific and commercial space purposes and are increasingly used by new entrants in space. Since the number of these satellites is growing, there is an increasing demand for suitable allocations in the space operation service in frequency bands below 1 GHz to cope with the attendant pressure on the requirements for telemetry, tracking and command. Nevertheless, it is important to ensure that these missions do not cause harmful interference to existing systems and incumbent services. Thus, Resolution 659 (WRC-15) invites the ITU-R to conduct sharing and compatibility studies on mitigation techniques to protect existing services in the frequency range MHz and MHz and in adjacent frequency bands. In that regard, WRC-19 Agenda Item 1.7 invites studies to accommodate spectrum requirements for TT&C in the space operation service, below 1 GHz, for NGSO satellites with short duration missions in existing allocations or consider an upgrade of the existing allocations or possible new allocations to the space operation service. With regards to the spectrum requirements for SOS for satellites with short duration mission, studies show that between MHz to 2.5 MHz is required for downlinks and between MHz and MHz is required for uplinks. The term short duration mission used in Resolution 659 (WRC-15) refers to a mission having a limited period of validity of not more than typically 3 years. It should be noted that, as indicated in Resolution 659 (WRC-15) recognizing a), the existing allocations to the space operation service below 1 GHz, where No applies, are not suitable for these satellite missions. The nature of these missions imply a short development and launch time, and uncertain orbital characteristics, which make formal coordination under No impractical. ISSUES To determine the spectrum requirements for telemetry, tracking and command for satellites with short duration missions and assess the suitability of existing allocations below 1 GHz to meet such requirements. To upgrade the existing allocations or identify new allocations to the space operation service within the frequency ranges MHz and MHz in order to accommodate such missions. To ensure that, if a new allocation to space operation service were added, incumbent services both in-band as well as in adjacent bands would be protected from potential harmful interference. CCPII _i

27 PRELIMINARY VIEWS CAN, USA These administrations support completing sharing and compatibility studies between NGSO satellites with short duration missions and the incumbent services with respect to invites ITU-R 1, 2, and 3 of Resolution 659 (WRC-15), and supports that frequency bands below 1 GHz should be considered for allocation changes only if agreed ITU-R studies demonstrate sharing feasibility. The frequency ranges described for consideration under invites ITU-R 3 overlap with allocations to critical global maritime distress and safety service (GMDSS) frequencies, identified in RR Appendix 15, and centered at MHz, MHz, MHz, MHz, MHz, and MHz, as well as frequencies used for the safety of life COSPAS/SARSAT system in the band MHz. Therefore, these administrations are of the view that CPM text must exclude the GMDSS frequency bands stated above, the COSPAS-SARSAT frequency range MHz and the 100 khz adjacent bands above and below the COSPAS-SARSAT frequency range (Res. 205 (WRC-15)) from consideration for possible new allocations or an upgrade of the existing allocations to the space operation service. Additionally, the frequency ranges for fixed and land mobile ( MHz, MHz, and MHz), meteorological satellite ( MHz), earth exploration satellite service ( MHz) and meteorological aids ( MHz) services are heavily used, and usage of the existing allocations is expected to increase in the future. These factors must be considered in any sharing and compatibility studies under this agenda item. These administrations are of the view that a single spacecraft with a lifetime of less than typically three years, where the operator does not launch replenishment or replacement spacecraft is a short duration mission. The operation of multiple spacecraft simultaneously can qualify as short duration if all spacecraft have lifetimes less than typically three years and therefore the frequency and orbital characteristics and capabilities exist for less than 3 years i.e., no replenishment/replacement. The case of a single (or multiple) spacecraft with a lifetime of less than typically three years, where the operator launches a single (or multiple) replenishment/replacement spacecraft(s) such that the operator has persistent frequency and orbital characteristics and capabilities longer than typically three years, is not considered a short duration mission. MEX Mexico supports the continuation of technical, operational, and regulatory studies that make it possible to assess possible new allocations to space operation service on a primary basis for NGSO satellites with short duration missions, considering the due protection of the services in which lifetime safety systems are used.

28 31 MEETING OF PERMANENT CONSULTATIVE COMMITTEE II: RADIOCOMMUNICATIONS July 16 to 20, 2018 Guadalajara, Jalisco, Mexico OEA/Ser.L/XVII CCP.II-RADIO-31/doc /18 18 July 2018 Original: English PRELIMINARY VIEWS FOR WRC-19 AGENDA ITEM 1.8 (Item on the agenda: 3.1 (SGT2)) (Document submitted by the Coordinator) SGT2A Radiolocation, Amateurs, Maritime & Aeronautical Coordinator: Michael Razi (CAN) Alternate Coordinator: Glenn Feldhake (USA) Rapporteur Agenda Item: Donald Jansky (USA) Alternate Rapporteur Agenda Item: Christopher Casarrubias (MEX) CCPII _i

29 Agenda item 1.8: to consider possible regulatory actions to support Global Maritime Distress Safety Systems (GMDSS) modernization and to support the introduction of additional satellite systems into the GMDSS, in accordance with Resolution 359 (Rev.WRC-15); BACKGROUND Resolution 359 (Rev. WRC-15) takes into consideration the activities of the International Maritime Organization (IMO) related to the GMDSS modernization (See Resolves 1) and the introduction of additional satellite systems into the Global Maritime Distress and Safety System (GMDSS) (See Resolves 2), and the consequential regulatory actions that may need to be considered in relation to these Resolves. Issue A GMDSS Modernization IMO has been advancing its studies on modernization of GMDSS and this information would be considered by ITU-R in development of any regulatory modifications that may be necessary in this regard. WP 5B is devoted to the task of addressing the necessary actions to modify the Radio Regulations, in addition to considering GMDSS modernization. This implies incorporating data exchange in VHF (VDES) and NAVDAT in replacement of NAVTEX. The Argentine Republic supports the making of these modifications, since it is considered that new technologies must serve to improve information security at sea. Issue B Introduction of additional GMDSS service provider This section presents the activities of the IMO related to the introduction of additional satellite systems into the GMDSS, recognizing that IMO has received an application to recognize an existing satellite system as part of the GMDSS. Further, resolves 2 of Resolution 359 (Rev.WRC-15) invites ITU-R to conduct studies, including consideration of the mobile-satellite service (MSS) allocations used and the potential impact of possible modifications to the provisions of the Radio Regulations on sharing and compatibility with other services and systems in the frequency band and adjacent frequency bands. The geography of the Argentine Republic presents the particularity that its territory encompasses part of the Antarctic area, due to which it is of utmost importance to have guaranteed coverage in areas with extreme climate characteristics. To date, only one mobile satellite system has been recognized by IMO for use in the GMDSS system of systems. Advances in communications technology, the maturity of commercial satellite operations, the introduction of competition into the satellite sector, and the deployment of non-geostationary satellite constellations have led the IMO to identify recognition of additional satellite systems to the GMDSS as an urgent work item. IMO s Maritime Safety Committee (MSC), at its ninety-second session (MSC 92), from 12 to 21 June 2013, considered the notification by the United States of the application of the Iridium mobile-satellite system for recognition and use in the GMDSS. The Committee, having noted that, in principle, there were no objections, agreed to refer the matter to the Sub-Committee on Navigation, Communications and Search and Rescue (NCSR) for evaluation. Following discussion at NCSR 1 (held from 30 June to 4 July 2014), MSC 94 (held from 17 to 21 November 2014) agreed that the International Mobile Satellite Organization CCPII _i

30 (IMSO) should undertake the technical and operational assessment of the Iridium mobile satellite system and provide a technical and operational assessment report for consideration by the NCSR Sub-Committee. IMSO submitted its report on the technical and operational assessment for consideration at NCSR 3 (held from 29 February to 4 March 2016). This Sub-Committee agreed that Iridium could be incorporated into the GMDSS subject to compliance with outstanding issues. The NCSR Sub-Committee invited the MSC to endorse this view, with the understanding that it, based on the evaluation reports from IMSO, would advise the Committee on final recognition, when the issues identified in the comprehensive list of conditions have been complied with. MSC 96 held in May 2016 has endorsed the list of conditions to be complied with by Iridium. This concluded a first stage review of Iridium's GMDSS application, IMO stating that approval ("recognition") can be granted pending completion of certain conditions. Iridium is currently in the process of completing those remaining conditions, which include: Integration of Iridium system with RCCs and MSI providers; ship earth station terminals made available for demonstration of ship-to-shore, shore-to-ship, and ship-to-ship GMDSS communications in compliance with the comprehensive list of outstanding items; Complete demonstration of compliance with all outstanding items of the comprehensive list in Fall of 2017 In addition to the above activities at the IMO, ITU is required to study potential impact of the regulatory provisions of the Radio Regulations. For example, considering that Appendix 15 (Rev. WRC-12) 2 of the Radio Regulations lists the frequency bands identified for provision of GMDSS, introduction of an additional satellite systems to provide GMDSS would require that frequency bands used by that system (e.g MHz used on the Iridium satellite system) are included in Appendix 15 (Rev. WRC- 12). In addition, the Resolution invites the WRC-19 to consider the studies undertaken as part of this agenda item and to take action in time for WRC-19. ITU-R WP 5B (WP 5B) and ITU-R WP 4C (WP 4C) have been involved in conducting such studies in support of Agenda Item 1.8. ITU-R WP5B is the responsible working party for this agenda item and Working Parties 4C and 7D were designated as concerned groups for the work, and Working Parties 1A and 3M were identified as interested groups. WP 4C is tasked to provide appropriate CPM text including characteristics of mobilesatellite and aeronautical mobile-satellite (R) service systems operating in the frequency bands identified by WP 5B, and any applicable Reports and Recommendations. Work on this matter is progressing in ITU-R WP 4C and 5B. The April 2017 meeting of WP 4C received a number of contributions on study of the above items, and outcome of these studies and discussions are captured in the Working Document towards Preliminary Draft New Report [GMDSS- SATREG]. Following Working Document are being developed: Working Document towards Preliminary Draft New Report [GMDSS-SATREG], addressing regulatory matters related to the identification of an additional satellite provider in the GMDSS (see, Document 4C/192 Annex 14); 2 Appendix 15 (Rev. WRC-12) is entitled Frequencies for distress and safety communications for the Global Maritime Distress and Safety System (GMDSS). CCPII _i

31 Working Document towards Preliminary Draft New Report [RAS-COMPAT], addressing protection of radio astronomy was carried further for development at future WP 4C meetings (see, Document 4C/192 Annex 15); and Working document towards preliminary draft CPM text for WRC-19 agenda item 1.8 (see, Document 4C/192 Annex 17). It is important to note that identification of an additional GMDSS service provider would bring forward the following benefits to the maritime community: Covering the entire globe including the critical Arctic and Antarctic (Polar) regions, which makes up Sea Area A4, where there is currently no GMDSS mobile satellite services available; Is an always on system as individual satellites pass overhead approximately every five to eight minutes depending on location. The movement of the satellites across the horizon provide the user with better look angles (i.e., ability to see the satellite) in rough seas, especially in northernmost and southernmost latitudes; Will enable both voice and data GMDSS communications in a single, small form factor maritime mobile terminal, at a low cost (currently two mobile satellite system terminals may be required to meet operational and regulatory needs of the vessel (voice and data) at much greater cost; Provide an opportunity for a redundant communications platform for the maritime community in the event there is a catastrophic outage which disables part, or all, of other satellite-based GMDSS services Will provide for more efficient and comprehensive distress and safety communications by providing the Rescue Coordination Center with immediate voice communications capability, vessel identification, and a means to contact the vessel in distress; Will provide, for the first time, vessel owners with a choice of satellite-based GMDSS services, including choice of equipment with the state-of-the-art technology, new service offerings, and competitive pricing; and May be integrated with vessel digital bridge systems consolidating equipment and displays for the crew to monitor, while eliminating clutter on the bridge; ISSUES What is the appropriate regulatory approach, including consequential modifications, to identify additional satellite systems to provide GMDSS? What sharing and compatibility studies may be required with other services and systems in the frequency band intended for GMDSS provision and adjacent frequency bands? PRELIMINARY VIEW: Issue A ARG With respect to Agenda Item 1.8, the Argentine Republic supports the making of the necessary actions to modify the Radio Regulations, in addition to considering GMDSS modernization. This implies CCPII _i

32 incorporating data exchange in VHF (VDES) and NAVDAT in replacement of NAVTEX, since it is considered that new technologies must serve to improve information security at sea. Issue B ARG, CAN, USA With respect to Agenda Item 1.8, these Administrations support the activities of IMO related to the introduction of additional satellite systems into the GMDSS, as well as activities underway in the ITU-R. Based upon successful conclusion of these activities, these Administrations support appropriate modification of the Radio Regulations such as Appendix 15, to provide for introducing additional satellite systems into the GMDSS.

33 31 MEETING OF PERMANENT CONSULTATIVE COMMITTEE II: RADIOCOMMUNICATIONS July 16 to 20, 2018 Guadalajara, Jalisco, Mexico OEA/Ser.L/XVII CCP.II-RADIO/doc.4575/18 29 June 2018 Original: English PRELIMINARY VIEW FOR WRC-19 AGENDA ITEM 1.9, ISSUE (Item on the Agenda: 3.1 (SGT2)) (Document submitted by the delegation of Canada) 1. Introduction This preliminary view from Canada addresses Agenda Item 1.9.1: autonomous maritime radio devices (AMRD) operating within the frequency band MHz, and whether regulatory action is required to protect global maritime distress and safety system (GMDSS) and AIS from their operations. Some AMRDs are used to enhance the navigation of ships and should continue to be used on channels that are already used by automatic identification system (AIS1 on MHz and AIS2 on MHz) and digital selective calling channel 70 ( ). Other AMRDs, that do not enhance navigation, should also use channels within Appendix 18 of the Radio Regulations that are not used for safety or navigational purposes. 2. Proposal Canada submits this preliminary view for the consideration of CITEL administrations in the work towards WRC-19. CCPII _i

34 Agenda Item 1.9.1: regulatory actions within the frequency band MHz for autonomous maritime radio devices to protect the GMDSS and automatic identifications system (AIS), in accordance with Resolution 362 (WRC-15) INTRODUCTION The need to recognize and identify free-floating objects such as fishing nets, towed unpowered ships and barges, derelict ships, floating ice, wave-gliders and drifting buoys, for safety of navigation or other purposes, is resulting in a growing number of autonomous maritime radio devices (AMRDs) using automatic identification system (AIS) technology on the market, and their number continues to increase. AIS is a proven technology for global maritime safety applications, providing identification, safety of navigation, aids to navigation, and locating functions. The use of AMRDs on AIS frequencies could have an adverse impact on the safety applications of AIS by overloading the capacity of the system, and occupying maritime mobile service identities that should be reserved for ship stations and aids to navigation. As an example, some fishing net indicators may be beneficial to the safety of ship stations. However, the increasing unregulated use of these indicator devices brings some negative effects to maritime safety, mainly in the following aspects: A large number of such devices causes a high density of visible objects in a specific vessel traffic service (VTS) area. This creates difficulties for the recognition of vessels, the assessment of navigation conditions, and the organization of vessel traffic. This increases the workload of vessel traffic services and may decrease their efficiency, compromising safety of the VTS area. Random and autonomous transmissions of such devices are harmful to the effectiveness and efficiency of the overall AIS network. This could reduce the effectiveness of receiving messages from AIS search and rescue transponders and result in delayed emergency responses. Given the forseen need for future new applications or devices, the maritime community overall would benefit from harmonized technical and operational specifications for AMRDs. This agenda item addresses AMRDs operating within the frequency band MHz, and whether regulatory action is required to protect global maritime distress and safety system (GMDSS) and AIS from their operations. Source /17 BACKGROUND RESOLUTION 362 (WRC-15) Autonomous maritime radio devices (AMRD) operating in the frequency band MHz, prescribes a study process for WP5B in four parts: 1) to determine the spectrum needs for the devices, 2) to categorize the various kinds of devices, 3) to conduct sharing and compatibility studies to ensure that no undue constraints are placed on the GMDSS and the AIS, and 4) to conduct studies to determine potential regulatory actions and appropriate frequencies within the band MHz. CCPII _i

35 The term AMRD is not part of the Database of ITU Terms and Definitions and needs clarification for a wider audience. At the May 2017 meeting of WP 5B, it concluded on the final definition of AMRDs and provides it to IMO and IALA: An AMRD is a mobile station; operating at sea and transmitting independently of a ship station or a coast station. Two groups of AMRDs are identified: Group A: AMRDs that enhance the safety of navigation, Group B: AMRDs that do not enhance the safety of navigation (AMRDs which deliver signals or information which do not concern the vessel can distract or mislead the navigator and degrade the safety of navigation). The devices discussed may use AIS technology; digital selective calling (DSC) technology; or transmit synthetic voice messages. Combinations of the technologies mentioned above can be found in equipment already available on the market. The ITU Bureau sent a circular letter to all administrations including a questionnaire on the distribution and applications of AMRDs. The objective of the questionnaire was to get a clear overview of these devices and to compile and categorize existing AMRDs being used in different countries. Responses were submitted to ITU-R Working Party 5B (WP 5B), the responsible group for this Agenda Item. The information was consolidated to give a general description of the applications. The applications described included uses such as diver emergency, buoy, fishnet indicators, object trackers, racing marks, and oceanographic meteorological sensors. Some AMRDs are deployed at sea, while others are carried by divers or used in the vicinity of a vessel. Although the intented use of AMRDs is at sea including coastal areas, AMRDs may be brought onto land or may be washed ashore by accident. The result shows that some devices are using AIS technology on channels AIS1 and AIS2. Other technologies, such as digital selective calling (DSC), synthetic voice, or a combination of technologies were also noted. Different transmitting power and intervals, message formats and unregulated maritime mobile service identities (MMSI) are used by many of these AMRDs. In addition to Radio Regulations (RR) Appendix 18 channels 6/16/70, AIS 1, AIS 2, and other frequency bands outside the maritime mobile service, some AMRDs operate on MHz or 406 MHz. It can be concluded from the survey that AMRDs lack harmonized technical standards and frequency bands. The types of applications of AMRDs also vary, and AMRDs could be used in areas where they could cause interference to the land mobile service if these devices operate within the same frequency bands. DISCUSSION Group A AMRD A Group A AMRD is defined as a mobile station; operating at sea and transmitting independently of a ship station or a coast station that enhances the safety of navigation. WP 5B has concluded that Group A devices should remain subject to International Maritime Organization (IMO) International Convention for the Safety of Life at Sea (SOLAS) regulations for the communication of information to navigators on board vessels. To enhance the safety of navigation, a Group A AMRD CCPII _i

36 provides information about hazard areas, such as an aid to navigation, and distress situations, such as a man overboard incident. Group A AMRDs are currently using AIS and DSC technology on the frequencies MHz (AIS 1), MHz (AIS 2) and MHz (ch70). Their operation should continue to be accommodated on these frequencies in Appendix 18 of the Radio Regulations (RR) that are appropriate for aids to navigation. No additional spectrum requirement for this category of devices has been identified. The draft list of Group A AMRD applications are presented in the working document toward a draft new recommendation ITU-R M.[AMRD] in WP 5B. It currently includes applications such as: man overboard, drifting wreck, drifting container, iceberg, and pollution hazards. The document also indicates restrictions on output power (1 Watt) and antenna heights (1 metre) for Group A AMRDs. In addition, Recommendations ITU-R M.1371, M.493, and M.585 are being updated to reflect the technical characteristics of Group A AMRDs corresponding to the technology used by the devices. Group B AMRD Group B AMRDs include other maritime applications such as divers, oceanographic research, and fishing nets. Under the existing definition, Group B AMRDs do not provide information that enhances the navigation of vessels, and their usage may distract or mislead the navigator thus degrading the safety of navigation. The spectrum requirements for Group B AMRDs include one 25 khz channel for AIS technology and up to three 25 khz channels for other technologies. Group B AMRDs should be operated on other designated frequencies within RR Appendix 18 that are not currently used for navigational purposes. The working document toward a draft new recommendation ITU-R M.[AMRD] also contains a list of Group B AMRD applications, and technical characteristics of maximum 1 Watt output power and antenna height of 1 metre. PRELIMINARY VIEW USA The United States supports the ITU-R studies prescribed in Resolution 362 (WRC-15) and these studies should also take into account the protection of the GMDSS and AIS. Canada Canada supports the identification of frequencies in Appendix 18 of the Radio Regulations for Group A AMRDs. This identification would include the frequencies MHz (AIS 1), MHz (AIS 2) and MHz (ch70) for Group A devices. Canada also supports regulatory measures to identify other frequencies in Appendix 18 of the Radio Regulations that are not currently being used for navigational purposes for Group B AMRDs. CCPII _i

38 Agenda Item 1.9.2: modifications of the Radio Regulations, including new spectrum allocations to the maritime mobile-satellite service (Earth to space and space-to-earth), preferably within the frequency bands MHz and MHz of Appendix 18, to enable a new VHF data exchange system (VDES) satellite component, while ensuring that this component will not degrade the current terrestrial VDES components, applications specific messages (ASM) and AIS operations and not impose any additional constraints on existing services in these and adjacent frequency bands as stated in recognizing d) and e) of Resolution 360 (Rev.WRC-15); BACKGROUND RESOLUTION 360 (REV. WRC-15) Consideration of regulatory provisions and spectrum allocations to the maritime mobile-satellite service to enable the satellite component of the VHF Data Exchange System and enhanced maritime radiocommunications, invites ITU-R to conduct, as a matter of urgency, and in time for WRC-19, sharing and compatibility studies between VDES satellite components and incumbent services in the same and adjacent frequency bands specified in recognizing d) and e) to determine potential regulatory actions, including spectrum allocations to the MMSS (Earth-to-space and space-to-earth) for VDES applications. To this end, the ITU-R has initiated sharing studies between the proposed VDES satellite (VDE-SAT) frequencies and the incumbent services in the same and adjacent bands so that this component does not impose any additional constraints on existing services in these and adjacent frequency bands as stated in recognizing d) and e) of Resolution 360 (Rev. WRC-15). The satellite component of the VDES could be beneficial towards enhancing maritime navigation and safety related applications on a global basis. Traditional maritime communication methods (i.e. voice) have been used for the transfer of the information required to improve the safety of navigation particularly in adverse conditions. More information (such as weather, ice charts, status of aids to navigation, water levels and rapid changes of port status) is required in real-time to improve operational decisions on land and on ship that will lead to safer and more efficient voyages. Shore authorities have also demonstrated interest in increasing the quantity of information retrieved from ships in real-time (such as voyage information, passenger manifest and pre-arrival reports) in a more efficient way to transmit and process this information as digital information. As a result of these additional requirements on maritime communications, WRC-15 made regulatory changes to Appendix 18 to facilitate the use of the terrestrial component of VHF Data Exchange system (VDES). These channels may be used by maritime authorities across the world to respond to increased data transfer and improve maritime safety and efficiency in the growing maritime environment. VDES is an extension of the very successful Automatic Identification System (AIS) used by the maritime community, while protecting the original function of AIS identification, position reporting and tracking. AIS, designed primarily as a collision avoidance system, and application specific messages (ASM) will continue to operate along with the new VDES channels. VDES is based on robust and efficient digital transmission rates through the aggregation of several 25 khz channels for increased throughput capacity. Once vessels have travelled outside the area of terrestrial coverage from shore stations, satellite networks could provide VDES capability to support and enhance safety and navigation. The satellite component of VDES is being further studied for WRC-19 to take into account existing services within and adjacent to the frequency band under consideration. CCPII _i

39 Under 5.225A, the adjacent frequency band MHz includes a primary allocation to the radiolocation service in some countries. Preliminary studies within ITU-R Working party 5B (WP 5B) concluded that compatibility between the radiolocation service and the maritime mobile satellite service (Earth-to-space) is feasible without imposing any additional constraints on the radiolocation service. Application of the radiolocation service in the frequency band MHz is limited to the space surveillance radars. Studies in WP 5B during the preparation for WRC-15, proposed a pfd mask for the maritime mobile satellite service to protect the incumbent fixed and mobile services. These studies are being considered during the WRC-19 cycle. Furthermore, WP5B is currently drafting a report on the technical characteristics and feasibility assessment of the VDES satellite component including two proposed alternative frequency plans. Frequency plan alternative 1 allow for utilization of the channels 24, 84, 25, 85, 26 and 86 in a shared manner between VDE-TER and VDE-SAT. Four channels 1024, 1084, 1025 and 1085 are shared between ship-to-shore and ship-tosatellite (VDE-SAT uplink) services Two channels 1026 and 1086 are exclusively reserved for ship-to-satellite (VDE-SAT uplink) services Four channels 2024, 2084, 2025 and 2085 are shared among shore-to-ship, ship-to-ship and satellite-to-ship (VDE-SAT downlink) services Two channels 2026 and 2086 are exclusively reserved for satellite-to-ship (VDE-SAT downlink) services. Two channels 2027(ASM 1) and 2028 (ASM 2) are shared between ship-to-shore, ship-toship, shore-to-ship and ship-to-satellite services Frequency plan alternative 2 allow for utilization of channels 24, 84, 25 and 85 primarily for VDE-TER, while channels 26 and 86 exclusively reserved for VDE-SAT uplink. VDE-SAT uplink is also possible in channels 24, 84, 25 and 85, but the VDE-SAT uplink in these channels do not impose constraints on VDE-TER. Frequencies are exclusively reserved for VDE-SAT downlink within the frequency range MHz to MHz, which is not channelized in RR Appendix 18. Four channels 1024, 1084, 1025 and 1085 are reserved for ship-to-shore services, but shipto-satellite (VDE-SAT uplink) services are possible without imposing constraints on ship-toshore services. Four channels 2024, 2084, 2025 and 2085 are reserved for shore-to-ship and ship-to-ship services, but ship-to-satellite (VDE-SAT uplink) services are possible without imposing constraints on shore-to-ship and ship-to-ship services. Four channels 1026, 1086, 2026 and 2086 are exclusively reserved for ship-to-satellite (VDE-SAT uplink) services. Frequencies are exclusively reserved for satellite-to-ship (VDE-SAT downlink) services within the frequency range MHz to MHz, which is not channelized in RR Appendix 18. Two channels 2027(ASM 1) and 2028 (ASM 2) are shared between ship-to-shore, ship-toship, shore-to-ship and ship-to-satellite services. CCPII _i

40 ISSUES What is the appropriate pfd mask to ensure compatibility with in-band fixed and mobile services? Are there any regulatory measures necessary to ensure no additional constraints are imposed on the incumbent services (fixed, mobile, radiolocation and radio astronomy) in adjacent frequency bands? PRELIMINARY VIEWS CAN Noting that the proposed alternatives are being discussed, Canada believes that other alternative channel plans must also be explored. In order to establish a comprehensive VDES channel plan for all VDES components, Autonomous Maritime Radio Devices (AMRDs) operating within the same frequency band must also be taken into account. These devices may use AIS technology; digital selective calling (DSC) technology; or transmit synthetic voice messages. Combinations of these technologies can be found in equipment already available on the market. AMRDs are being addressed under Agenda Item In view of this, VDES channel plans should take into account frequencies for AMRDs. USA The United States supports the ITU-R studies prescribed in Resolution 360 (Rev. WRC-15) and these studies should also take into account the protection of existing terrestrial services which operate in these and adjacent frequency bands. CCPII _i

42 Agenda Item 1.10: to consider spectrum needs and regulatory provisions for the introduction and use of the Global Aeronautical Distress and Safety System (GADSS), in accordance with Resolution 426 (WRC-15) BACKGROUND While air travel in recent years has represented some of aviation s safest years in terms of the number of accidents, the tragedy of Malaysia Airlines flight 370 in March 2014 highlighted needed improvements in the global air navigation system requiring urgent attention. To address these improvements, the aviation community embarked on a global effort to develop GADSS, and International Civil Aviation Organization (ICAO) forged consensus among its Member States and the international air transport industry on the near-term priority for a more comprehensive method of tracking civilian airline flights, regardless of their global location or destination. The International Civil Aviation Organization (ICAO) held a Special Meeting on Global Flight Tracking of Aircraft in Montreal May 2014, and formed an ICAO ad hoc Working Group to develop a concept of operations to support future development of GADSS. A draft version of a concept of operations for GADSS, was developed by the ICAO Ad-hoc WG on flight tracking and introduced at the 2 nd ICAO High Level Safety Conference (2 nd HLSC, 2 5 February 2015). The 2 nd HLSC recommended that ICAO should expeditiously finalize and use the GADSS for the implementation of normal and abnormal aircraft tracking; autonomous distress flight tracking; search and rescue (SAR) activities; automatic retrieval of data from cockpit voice and flight data recorders; and related procedures including management of such information. In June 2015 the Ad-hoc WG delivered a final version of the GADSS concept of operations to ICAO, for consideration to publish as an ICAO document under the authority of the Secretary General. As a result of expected developments in the implementation of various elements of GADSS, modifications to the Radio Regulations may be required to facilitate emerging needs of the aviation community and related distress and safety agencies. This agenda item was adopted at WRC-15 with sufficient flexibility to address potential modifications to the Radio Regulations required to allow implementation of the GADSS, taking into consideration the incumbent services that may be impacted as a consequence of these potential modifications. Specifically, Resolution 426 (WRC-15) invited the ITU- R to conduct relevant studies taking into account information provided by ICAO on the requirements for both the terrestrial and satellite components of GADSS. During recent meetings, the Frequency Spectrum Management Panel (FSMP) of ICAO provided guidance on the type of spectrum required for each of the foreseen GADSS functions. GADSS Spectrum Guidance * Function Normal Tracking Surveillance Tracking Distress Tracking Data Retrieval (not used for real-time functions) Spectrum Category A B C A A: any type of spectrum properly allocated, on a primary basis, for the function being performed B: only protected aeronautical safety spectrum can be used. CCPII _i

43 C: only protected aeronautical safety spectrum, or protected distress spectrum (e.g., MHz), can be used *This table is not intended to imply that any new spectrum allocations are necessary to support GADSS. The above guidance provided by the ICAO FSMP on the type of spectrum to be used for the identified functions, can be further described by separating the individual functions and quantifying what is available to support that function, as follows: 1) Normal tracking is identified as the means of following an aircraft throughout its entire flight within the context of availability of position reporting at least once in 15 minutes. This function is deemed to be under the purview of the airline or company operating the aircraft. More than one method is available for an airline or company to accomplish flight following or normal tracking of a flight. Spectrum requirements for normal tracking were identified at WRC-15. 2) Surveillance tracking is a specific air traffic control function that is accomplished in accordance with ICAO Standards and Recommended Practices relative to airspace separations standards, technical standards and also the onboard avionics certification. No additional spectrum requirements have been identified by ICAO for this capability. 3) Distress tracking, in the operational context, will occur during emergency conditions of an aircraft. This is a performance-based requirement which is not technology-specific. Performance requirements include the ability to be manually activated, operate in the event of aircraft power loss, and communicate information to relevant authorities such as search and rescue and air traffic services. Principle methods being considered within ICAO for this function include the use of emergency position-indicating radiobeacons (EPIRBs) and emergency locator transmitters distress tracking (ELT(DT)) both of which operate on MHz, which is already allocated to the mobile satellite service (Earth-to-space). No additional spectrum requirements have been identified by ICAO for this capability. 4) Data retrieval in respect to the transmission of flight data is an operational capability that is still under discussion within the responsible operational and technical Panels of ICAO. Until there is maturity regarding an agreed method to accomplish flight data retrieval, it remains premature to determine any potential for additional new spectrum requirements. ICAO and ITU-R continue to work closely together as discussions of spectrum requirements for data retrieval progress. Some of the key issues that have been identified with the development and implementation of GADSS, which are expected to be addressed by ICAO include: What are the data traffic requirements for different system components of GADSS (such as the aircraft tracking, autonomous distress and flight data recovery systems) and their terrestrial and satellite components at each phase of the operation? What are the radiocommunication requirements related to safety-of-life applications? What are the performance criteria for terrestrial and satellite systems? After an analysis of the existing allocations to the relevant aeronautical services, is any additional spectrum required? If additional spectrum is required, would sharing and/or compatibility with existing services be possible? CCPII _i

44 ICAO has communicated, in a response to WP5B, that their initial expectation is that the three forms of tracking (normal, surveillance and distress) do not require additional spectrum allocations. Studies are continuing regarding the operational performance and spectrum requirements for data retrieval. PRELIMINARY VIEW: Brazil, Canada, USA 1. The quantification and characterization of the radiocommunications requirements for both the terrestrial and satellite components of GADSS are the responsibility of ICAO; 2. Based on those requirements, relevant studies should be conducted in the ITU-R to review existing regulatory provisions and determine if additional regulatory changes are needed; 3. ITU-R studies should be done in coordination with ICAO. CCPII _i

46 Agenda Item 1.11: to consider the results of ITU-R studies, take necessary actions, as appropriate, to facilitate global or regional harmonized frequency bands to support railway radiocommunication systems between train and trackside within existing mobile service allocations, in accordance with Resolution 236 (WRC-15) BACKGROUND For many years the railway industry has been integrating a multitude of wireless systems for operational applications to improve railway traffic control, passenger safety and improve security for train operations and to meet the needs of a high-speed railway environment. As the railway transportation systems are evolving, the infrastructure investment and the need to integrate different technologies in order to facilitate various functions, for instance, dispatching commands, operating control and data transmission into railway train and trackside systems becomes even more essential. Timely studies have been requested on technologies providing for railway radiocommunication and international standards and harmonized spectrum would facilitate worldwide deployment of radiocommunication systems between train and trackside. The ITU Radiocommunication Sector (ITU-R) Study Group 5 is studying relevant technical and operational characteristics for railway radiocommuncation systems. Some of the regional railway communities are considering a successor to GSM-R (GSM for Railway), as the forecast obsolescence of the 2G-based GSM-R technology is envisaged around In order to meet future demands of train control and operation including passenger services, some national and international railway organizations have begun investigations on new technologies for next generation radiocommunication systems between train and tracksides with required technology lifespans of multiple decades. The 3GPP is considering standardization of the next evolution of train-to-trackside communications technologies which is supported by the International Union of Railways (UIC). According to the Motorola Solutions contribution 3 to the Asia-Pacific Telecommunity (APT), September 2016 meeting, TETRA, 4G LTE and 5G technologies with low latency are candidates for future train-to-trackside communications. In addition, IP based RAN will replace the existing circuit Radio based GSM-R network for train-to-trackside communications. In Mexico, the project called Inter-urban passenger train from Toluca to Valley of Mexico, which will be connecting the metropolitan area of the Valley of Toluca to the western side of Mexico City, is currently being built to improve mobility in the Valley of Mexico Metropolitan Area. In the context of said project and as part of the criteria for its design and operation, use of the technological solution provided by the GSM-R standard in the frequency band / MHz was proposed for the purpose of meeting connectivity requirements. GSM-R systems have traditionally operated in this frequency band, because it is partially covered by the GSM 900 standard for mobile phones, mainly used in Europe in the / MHz range. Likewise, the frequency band of interest has the allocation in the National Frequency Allocation Table to Mobile and Aeronautical Mobile, both as a primary service, where the frequency segment / MHz is allocated for national aeronautical mobile radiocommunication service. 3 The Motorola Solutions contribution to the Asia-Pacific Telecommunity (APT) will be available as an information document at the CITEL November 2016 meeting. CCPII _i

47 Despite the above, this alternative entailed various implications for Mexico, namely: a) The frequency band / MHz is granted in concession for the provision of national mobile broadband telephony. As a result, if this frequency band is used, geographical restrictions would have to be imposed on the base stations of the mobile broadband telephony service along the entire railroad line, a mechanism that would not necessarily guarantee protection of the railway systems. b) Segment / MHz has been viewed as one of the viable alternatives for operating business narrowband systems, because this segment benefits from the standards for trunking service. c) Aeronautical mobile service applications operate in the frequency bands / MHz, as a result of which, if additional spectrum is required for high-speed trains, there might be difficulties because of the coexistence of train operations on the basis of the GSM-R standard and aeronautical mobile services. d) To not give continuity to the operation of aeronautical mobile services, if it is eventually decided that it is not feasible to have aeronautical mobile services and operations of the GSM-R standard coexist. e) Depending on the railway network s communication needs, only minimum needs can be met, as a result of which, in the event that said network is diversified or enlarged, it would be impossible to grant additional spectrum. In that respect, even when the band / MHz is considered apt for operating the GSM-R systems, it was determined that, in Mexico, in the ranges of MHz and MHz, only the operation of two blocks of 2.6 MHz for the uplink and downlink, respectively, would be feasible. ISSUES To determine spectrum needs for the implementation of railway radiocommunication systems between train and trackside. To identify global or regional harmonized frequency bands, if needed, for the implementation of railway radiocommunication systems between train and trackside, within existing mobile service allocations. Determine how this identification would be done. To determine potential technical and operational characteristics and implementation of railway radiocommunication systems between train and trackside in the mobile service to assess compatibility with other services. To determine mitigation techniques to protect the existing primary systems of the other services within frequency bands with existing mobile service allocations. PRELIMINARY VIEWS: B, CAN, ECU Agenda item 1.11 is restricted to examining spectrum for railway radiocommunication systems between train and trackside in spectrum already allocated to the mobile service; therefore, it can be satisfied through ITU-R Recommendations and Reports without the need of changes to the Radio Regulations. CCPII _i

48 MEX The process of identifying possible radio spectrum segments for railway radiocommunication systems should be based on the premise that they should not be located in the bands currently allocated or authorized by administrations for mobile broadband telephony applications, so as to prevent possible harmful interferences or incompatibility with each administration s spectrum allocation plans. Although it is true that Mexico is at an advantage with respect to identifying spectrum for high-speed railway systems in frequency bands identified for IMT, because of the experience gained from the difficulty of allocating spectrum for this type of system, the Administration of Mexico believes that frequency ranges where the administrations do not have allocations for mobile broadband telephony applications should be taken into account. The Administration of Mexico is willing to share experiences with respect to the allocation of frequencies to high-speed railways in the sessions where this subject will be discussed. Furthermore, the Administration of Mexico is of the opinion that harmonized frequency bands should be identified for the implementation of high-speed railways in Region 2 and that ITU-R Recommendations and Reports are the best mechanisms to address item 1.11 on the WRC-19 agenda, without the need to make any amendments to the Radio Regulations.

50 Agenda Item 1.12: to consider possible global or regional harmonized frequency bands, to the maximum extent possible, for the implementation of evolving Intelligent Transport Systems (ITS) under existing mobile-service allocations, in accordance with Resolution 237 (WRC-15) BACKGROUND Research and development has been ongoing for decades to integrate information and communication technologies into vehicle systems to improve traffic management and assist safe driving. This is expected to be important in resolving road traffic problems such as congestion and accidents. ITS applications, including ETC (Electronic Toll Collection) and millimetre-wave radars, have already been deployed worldwide. The 3 rd Generation Partnership Project (3GPP) is standardizing the radio interface, system architecture and service requirements of LTE-based V2X Services for ITS application and new vehicular radiocommunication technologies and ITS broadcast systems are emerging. New connected vehicles will use intelligent technologies in the vehicles combined advanced traffic management, advanced traveler information, advanced public transportation management system and/or advanced fleet management systems. Vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications, called co-operative ITS, have been developing to achieve safe drive support systems. Given the expected exponential growth in ITS deployment and the enormous size and safety impact of the global automotive industry, now is the time for consideration of spectrum harmonization for ITS applications globally and/or regionally. International standardization activities for ITS info-communication systems have been conducted at the global and regional levels (ITU-R, ISO and ETSI, CEN, ARIB) and in private sector (IEEE, SAE). Several recommendations and reports have been published: - Recommendation ITU-R M.1890, Intelligent Transport Systems Guidelines and Objectives, Recommendation ITU-R M , Intelligent Transport Systems Dedicated Short Range Communications at 5.8 GHz, Recommendation ITU-R M , Millimetre wave radiocommunication systems for ITS applications, Report ITU-R M.2228, Advanced Intelligent Transport Systems (ITS) radiocommunications, Recommendation ITU-R M.2084, Radio interface standards of vehicle-to-vehicle and vehicle-to-infrastructure communications for intelligent transport systems applications, Report ITU-R M.[ITS USAGE] Intelligent transport systems usage Report in ITU Member States, to be published in 2016.] In the U.S. and Europe, the study of sharing ITS spectrum to be used for V2V and V2I, with Radio Local Area Network (RLAN) (WRC-19 agenda item 1.16), has begun. With the perspective of efficient use of the spectrum, some frequency bands which have been used for ITS applications for many years, or are planned to be used, and are allocated for mobile applications are being actively studied by some administrations and regions with a view to enable sharing with other applications. ISSUES To determine spectrum needs for the evolving ITS applications. CCPII _i

51 To identify global or regional harmonized frequency bands, if necessary, for the implementation of evolving ITS applications under existing mobile service allocations. To determine a definition for the applications covered under ITS radiocommunication systems. To determine potential technical and operational restrictions or mitigation techniques for evolving ITS applications operating in the mobile service to facilitate sharing with systems of incumbent services. To assess possible linkage to agenda item 1.16 dealing with frequency bands between MHz given that some ITS systems operate in the upper part of that frequency range. PRELIMINARY VIEWS CAN Canada is of the view that the agenda item 1.12 is restricted to studying spectrum for intelligent transport systems in spectrum already allocated to the mobile service; therefore, Canada is of the view that this agenda item can be satisfied through ITU-R Recommendations and Reports without the need of changes to the Radio Regulations.

53 Agenda item 1.13: To consider identification of frequency bands for the future development of International Mobile Telecommunications (IMT), including possible additional allocations to the mobile service on a primary basis, in accordance with Resolution 238 (WRC-15); BACKGROUND Mobile broadband plays a crucial and fundamental role in providing access to information for businesses and consumers worldwide. According to ITU statistics, published on July 2016, In developing countries, the number of mobile-broadband subscriptions continues to grow at double digit rates, reaching a penetration rate of close to 41 percent. have grown at more than 20% per year over the past five years and it is expected that they will reach 4.3 billion worldwide The total number of mobile-broadband subscriptions is expected to reach 3.6 billion by end Mobile broadband users are also demanding higher data rates and are increasingly using mobile devices to access audio-visual contents. The mobile industry continues to drive technological innovations in order to meet these evolving user demands. Research and development efforts from both industry as well as academia are facilitating the use of spectrum in bands above 6 GHz for mobile broadband. These efforts span the globe. Some countries and regions have also begun making spectrum available for mobile broadband applications in higher frequency bands in order to provide the benefits of these innovations to businesses and consumers worldwide. The evolution of International Mobile Telecommunications (IMT), which provides wireless telecommunication services on a worldwide scale, has contributed to global economic and social development. IMT systems are now being evolved to provide applications such as enhanced mobile broadband, massive machine-type communications and ultra-reliable and low-latency communications. Many of these ultra-low latency and very high bit rate applications will require larger contiguous blocks of spectrum than those available in the frequency bands currently identified for IMT. This has resulted in the need to address higher frequency bands to find these larger blocks of spectrum in the bands indicated in Resolution 238 (WRC-15), In early 2012, ITU-R embarked on a program to develop IMT for 2020 and beyond. In November 2015, ITU-R approved Recommendation ITU-R M.2083 IMT Vision - Framework and overall objectives of the future development of IMT for 2020 and beyond, which highlights three key usage scenarios for trends in future IMT-2020 systems: communications at very high data speeds, numerous connected devices, andenhanced mobile broadband, massive machine type communications, and ultra-reliable and low latency applicationscommunications. The success of these usage scenariostrends, in both developed and developing countries, will rely on both spectrum availability for the terrestrial IMT-2020 systems and the support of high capacity backhaul capabilities (including fiber, wireless, satellite and microwave solutions). Recognizing the need to consider the spectrum in the range to 86 GHz to support the terrestrial component of IMT in higher frequency bands, while protecting existing services, World Radiocommunication Conference (WRC) 2015 approved WRC-19 agenda item ITU-R, standards development organizations, and industry continue to progress the work on the development of IMT The central topic is the need to conceive, from the outset, high frequency bands that are harmonized enough to foster economies of scale and meet the short-, medium- and long-term spectrum requirements, and to incorporate the use of new technologies that can benefit from the physical features of various 4 CCPII _i

54 frequency ranges, whose bandwidths would enable lower latencies and higher transmission rates for the transmission and exchange of mobile data. Beyond the results of the last WRC-15, the challenge for the future is now to focus efforts on the GHz to 86 GHz frequency range. This is a great opportunity to meet the technical and spectral needs for the future development of IMT-2020 systems, better known as 5G. [Source: Doc. 4297] WRC-19 agenda item 1.13 (Resolution 238 (WRC-15)) decided to study candidate frequency bands in portion(s) of the frequency range between and 86GHz for IMT identification. In order to better understand the situation in the Americas region with-respect-to this agenda item, a Questionnaire on Usage and Future Plan of Frequency Bands Under Study in Agenda Item 1.13 of WRC-19, in Americas Region was proposed, and responses from eight administrations were received and the compilation of the answers were compiled in document (CCP.II- RADIO/doc.4310/17) in the XXIX PCCII meeting (Orlando, Florida). ISSUES To determine the spectrum needs for the terrestrial component of IMT (IMT-2020) in the frequency range between GHz and 86 GHz. To assess the sharing/compatibility (co- and adjacent-band) of terrestrial IMT-2020 with systems of other services with allocations in each of the bands between GHz and 86 GHz listed above. Based on these spectrum needs and sharing/compatibility studies, to determine which bands or portions of the bands listed above should be candidates for identification for the terrestrial component of IMT including the bands in which primary allocation to mobile will be required. Since some bands indicated for study under AI 1.13 are common to those indicated for a) HAPS under AI 1.14, b) non-gso under AI 1.6 and c) GSO feeder links under AI 9.1.9, linkages to these items need to be considered including the details in the respective associated Resolutions. PRELIMINARY VIEWS ARG The Argentine Republic supports the conduction of studies related to Agenda item 1.13 of the WRC-19 Agenda, recognizing the work made by Task Group TG 5/1, in all the frequency bands identified in Resolves 2 of resolution 238 (CMR-15), a saber: GHz GHz, GHz, GHz, GHz, GHz, GHz and GHz, which have allocations to the mobile service on a primary basis; and GHz, GHz and GHz, which may require an additional allocation to the mobile service on a primary basis in this frequency band. The passive services operating in the frequency bands adjacent to those detailed above should be protected based on the results of the sharing studies approved by TG 5/1 of ITU-R and in compliance with the provisions of the Radio Regulations.

55 Agenda Item 1.13 is key to the future development of IMT systems for the delivery of IMT-2020 services. The aim of IMT-2020 is to create a more hyper connected society by more comprehensively, and intelligently, integrating LTE, Wi-Fi and cellular IoT technologies, together with at least one new IMT-2020 radio interface. This will allow mobile networks to dynamically allocate resources to support the varying needs of a diverse set of connections ranging from industrial machinery in factories, to automated vehicles as well as smartphones. A central component in the evolution of all mobile technology generations has been the use of increasingly wide frequency bands to support higher speeds and larger amounts of traffic. IMT-2020 is no different, ultra-fast IMT-2020 services will require large amounts of spectrum including above 24 GHz where wide bandwidths are more readily available. Spectrum above 24 GHz is well recognized worldwide as being the key component for the data intensive IMT-2020 services. Without them, IMT-2020 won t be able to deliver significantly faster data speeds or support projected extensive mobile traffic growth. With that in mind, we support appropriate sharing and compatibility studies under Agenda Item 1.13 in the bands GHz, GHz, GHz, GHz, GHz, GHz and GHz. Such studies should consider that the significant extra capacity of IMT-2020 systems will need to be perfectly integrated with heterogenous networks, including fibre, satellite and microwave systems, taking into account their specific benefits which are crucial to developing countries. The Brazilian Administration is analyzing the current status of all the bands listed under agenda item As such, preliminary studies conducted by the Brazilian Administration and submitted to the ITU-R TG 5/1, using propagation models, parameters and modelling provided by the relevant groups in the ITU, suggest that sharing is feasible between IMT and other services. Further studies are ongoing considering other services and applications. Based on these studies Brazil is considering support identification of the bands GHz and GHz, or parts thereof. Additionally, these two bands, known as the 26 GHz and the 40 GHz bands are the ones for which more interest has been expressed in the ongoing discussions at the ITU-R TG 5/1. Canada The availability of globally or regionally harmonized spectrum for IMT above 24 GHz is key to the future development of IMT systems for the delivery of next generation services. For this reason, Canada has supported and participated in the studies under WRC-19 agenda item 1.13, taking place in ITU-R TG 5/1, in the following frequency bands: GHz, GHz, GHz, GHz, GHz, GHz, GHz and GHz, which have allocations to the mobile service on a primary basis; and GHz, GHz and GHz, which may require additional allocations to the mobile service on a primary basis. In making this spectrum available for IMT per Resolution 238 (WRC-15), Canada is of the view that passive services in frequency bands adjacent to those under study in AI 1.13 need to be protected taking into account the relevant provisions of the Radio Regulations. Regulatory limits for the protection of any service should be technically derived, based on studies using the parameters and deployment scenarios provided by the expert ITU-R Working Parties, such that sufficient protection is provided to co-primary services while minimizing the impact on the delivery of IMT services in terms of cost, coverage and performance to the extent possible. CCPII _i

56 Canada is of the view that most cases involving terrestrial interference paths (e.g. between IMT and Earth stations or IMT and the FS) can be resolved through domestic decision-making and/or bilateral coordination due to the short distances involved. Further discussion may be needed on the precise measures that may be necessary at the ITU in support of coordination, noting that coordination with Earth stations is already addressed in Appendix 7 of the Radio Regulations. With regard to the identification of specific bands, Canada has the following views at this time, assuming that questions related to the protection of adjacent and co-channel primary services are resolved: GHz: This is a priority band for consideration for identification for IMT, in full or in part, due to the potential for global use. Canada is currently consulting on the potential to make the frequency range from GHz available for flexible use for terrestrial fixed and mobile services prior to WRC-19; therefore, identification for IMT of spectrum in this sub-band is a high priority for Canada GHz: This band is of lesser priority to Canada at this time considering, among other factors, study results showing interference to aeronautical radionavigation systems and that more spectrum is available in other candidate frequency ranges or groups of candidate frequency ranges GHz: Canada is currently consulting on the potential to make the band GHz available for flexible use for terrestrial fixed and mobile services prior to WRC-19; therefore, identification for IMT of this spectrum in Region 2 is a high priority for Canada. For the band GHz, decisions on identification need to take into account the global identification for HDFSS, for ubiquitous deployment of satellite terminals, as per footnote 5.516B GHz: For the band GHz, considerations on identification for IMT need to take into account the identification for HDFSS, for ubiquitous deployment of satellite terminals, in Region 2 as per footnote 5.516B. For the band GHz, consideration for identification of spectrum for IMT is a priority, considering the potential benefits of economies of scale of the development of IMT equipment that can operate over a broad frequency range GHz: Consideration for identification for IMT of spectrum in this range is a priority considering the potential benefits of economies of scale of the development of IMT equipment to operate over a broad frequency range GHz: The consideration for identification for IMT of this band is a lesser priority compared to spectrum in lower frequency bands GHz: The consideration for identification for IMT of this band is a lesser priority compared to spectrum in lower frequency bands GHz: The consideration for identification for IMT of this band is a lesser priority compared to spectrum in lower frequency bands GHz: The consideration for identification for IMT of this band is a lesser priority compared to spectrum in lower frequency bands GHz: Canada is currently consulting on the potential to make the entire frequency range from GHz available for flexible use for terrestrial fixed and mobile services prior to WRC- 19; therefore, identification for IMT of spectrum in this band is a relatively high priority for Canada GHz: Canada s priority for the use of this band is for FS for backhaul in support of IMT systems using other bands. Consideration for identification for IMT in addition to this backhaul is a lesser priority. CCPII _i

57 81-86 GHz: Canada s priority for the use of this band is for FS for backhaul in support of IMT systems using other bands. Consideration for identification for IMT in addition to this backhaul is a lesser priority. All of the above views remain preliminary and subject to change as discussions progress. Colombia While all bands remain suitable for identification at this stage, Colombia would like to make the following observations regarding the lower portions of the range, from GHz to 43.5 GHz: Responses received until the previous meeting of CCP.II to the questionnaire show that, except for a few cases, there are either no services licensed in these bands or the services belong to the fixed service category. When they belong to other service categories (such as FSS), most of them occupy a relatively small (500MHz or less) bandwidth with-respect-to the total range being considered for study (e.g GHz for 24.25GHz 27.5GHz). Other regions initiated discussions on suitable bands among the lists of candidate bands. As an example, Europe ([2], [3]) identified the GHz 27.5 GHz as a pioneer band, while other bands up to 43.5 GHz have been positively considered. With the view of seeking not only regional but global frequency harmonization to the possible extent, it is positive to take under consideration activities of other regions. The lower portions of the range would provide comparatively more suitable propagation characteristics for deployment compared to the upper portions, considering that some installations could cover outdoor and indoor environments with some Non-Line-of-Sight (NLoS) situations. Based on the considerations above, Colombia is of the initial view that the lower portions of the frequency range (from GHz to 43.5 GHz) provide good opportunities in terms of availability, technical performance and potential for global harmonization. Colombia would like to invite other members to consider this initial view for consideration and collaboration towards a regional (and possibly global) harmonization of the frequency bands. USA Support studies under WRC-19 agenda item 1.13 and take appropriate action based on the results of these sharing and compatibility studies in accordance with Resolution 238 in the following bands: GHz, GHz, GHz, GHz, GHz, GHz, GHz and GHz, which have allocations to the mobile service on a primary basis; and GHz, GHz and GHz, which may require additional allocations to the mobile service on a primary basis. Mexico Regional harmonization for agenda item 1.13this item on the agenda should consider similar approaches in terms of allocations and plans for the radio spectrum, in order to favor cost reduction and encourage the development of a sustainable ecosystem for the deployment of IMT systems and which, at the same time, does not prevent the use of services allocated on a primary basis to the frequency bands under study. CCPII _i

58 A public survey is currently being prepared in Mexico to identify the IMT spectrum requirements from GHz to 86 GHz. To this end, we plan to study the discussions and documents issued by the different working groups of both the International Telecommunication Union (ITU) and CITEL regarding regional and global spectral requirements for IMT at the frequencies of to 86 GHz. For this reason, we deem it necessary to conduct, in the best terms possible,mexico supports the planned studies that are being conducted in the various ITU-R Study Groups on protection criteria, on sharing and compatibility in the bands agreed on through Resolution 238 (WRC-15), i.e., for the purpose of not imposing new regulatory or technical limitations to services the segments of GHz, GHz, GHz, GHz, GHz, GHz and GHz, to which the frequency bands are currently allocated on a primary basis, in order for the CITEL administrations to make better, more fully-grounded decisions to achieve regional or global harmonization for the future development of IMT-2020 systems and the correct operation of services allocated on a primary basis in the frequency bands under study.

60 Agenda Item 1.14: to consider, on the basis of ITU-R studies in accordance with Resolution 160 (WRC- 15), appropriate regulatory actions for high-altitude platform stations (HAPS), within existing fixedservice allocations BACKGROUND Article 1.66A of the ITU Radio Regulations define a high-altitude platform station (HAPS) as "a station on an object at an altitude of 20 to 50 km and at a specified, nominal, fixed point relative to the Earth". Agenda Item 1.14 was adopted by WRC-15 to consider, in accordance with Resolution 160 (WRC-15), regulatory actions that can facilitate deployment of HAPS for broadband delivery. Resolution 160 resolves to invite ITU-R to study additional spectrum needs of HAPS, examining the suitability of existing HAPS identifications and conducting sharing and compatibility studies for additional identifications in existing fixed allocations in the GHz band on a global basis and in GHz and GHz bands in Region 2 exclusively. Currently there are 3 spectrum bands identified for HAPS in the fixed services. These are: GHz and GHz, GHz and GHz, MHz (HAPS-ground) and MHz (ground-haps). However, spectrum needs of next-generation HAPS cannot be accommodated within these identifications due to either geographical restrictions or technical limitations which impairs their operation. The global identification for HAPS links (which is in the GHz band fixed-service allocation paired with the GHz band fixed-service allocation) suffers from the effects of rain fade attenuation that severely limit service provision over high-precipitation geographies. The remaining 2 available bands ( GHz paired with the frequency band GHz, and MHz paired with MHz) have been identified by a very limited amountnumber of countries, none of which is within ITU Region 2. ITU-R Working Party 5C developed a Preliminary New Draft Recommendation (PDNR) assessing spectrum needs for broadband HAPS at an approximate 4 GHz aggregate capacity. BROADBAND HAPS (connectivity applications) According to the UN Broadband Commission, broadband HAPS can play an important role in meeting the need for highspeed, reliable broadband, particularly in large, underserved areas. While prices for mobile broadband are falling rapidly, mobile networks have only been deployed in 38% of least developed countries. With these challenges in mind, one pillar perhaps the central pillar of the solution is the broader deployment of broadband backhaul. Advances in aeronautics and transmission technologies have significantly improved the capabilities of HAPS to provide effective connectivity solutions and meet the growing demand for high capacity broadband networks, particularly in currently underserved areas. Recently conducted full-scale test flights have shown that solar-powered platforms in the upper-atmosphere can now be used to carry payloads that offer connectivity over large areas in a reliable and cost-effective way, and a growing number of applications for the new generation of HAPS are being developed. The technology appears particularly well suited to complementing terrestrial networks by providing backhaul. A number of advantages of the new generation of HAPS are foreseen: CCPII _i

61 Wide-area coverage: A single plane will be able to serve footprints larger than 100 km in diameter, and recent technological advances in the development of optical inter-haps links now allow the deployment of multiple linked HAPS, in fleets that can cover whole nations. Low cost: The cost of operating solar platforms is projected to be significantly lower than other connectivity solutions in many areas, while mass production of the aircraft will significantly lower upfront capital expenditure for deployment. Reach: HAPS platforms will operate at around 20 km above ground, which reduces their vulnerability to weather conditions that may affect service, provides large coverage areas and avoids interference caused by physical obstacles. Rapid deployment and flexibility: It will be possible to deploy HAPS services without long lead times and it is relatively simple to return solar platforms to the ground for maintenance or payload reconfiguration. Geographical reach: HAPS that use the architecture of solar platforms can also provide connectivity where it is impossible to deploy terrestrial infrastructure: remote sites on land or sea. Environmentally friendly: HAPS can run exclusively on solar power for long periods, connecting people with almost no environmental impact. Spectrum harmonization and utilization is facilitated by common worldwide identifications. International regulatory flexibility can enable improvements in global connectivity by encouraging national regulators to permit operation of higher-speed Internet access services over new, complementary platforms, while ensuring protection of existing services. Additionally, harmonization of spectrum promotes economies of scale and commonality of equipment. BROADBAND HAPS (specific applications) Broadband HAPS for specific applications are designed to focus on multiple usage cases, including: Response to natural disasters. Fire detection, monitoring, and firefighting. Law enforcement with communication needs across local actors and regional headquarters. Resource exploration missions for communication between exploration teams and regional home base. SHARING STUDIES ITU-R Working Party 5C (WP 5C) is the group responsible for Agenda Item WP 5C has, in turn, established a specific Sharing Studies Drafting Group to examine the compatibility between HAPS and services operating or planning to operate in the bands under study as per Resolution 160 (WRC 15). Further resolves 1 of Resolution 160 (WRC-15) asks that ITU-R studies on AI 1.14 include sharing and compatibility studies to ensure protection of existing services allocated in the frequency ranges identified and, as appropriate, adjacent band studies, taking into account studies already performed in ITU-R. WP 5C has identified and carried out a number of sharing and compatibility studies to be conducted, including adjacent band studies, The draft studies are currently located in the Working Party 5C Chair s Report. Formatted: Font: Formatted: Font: CCPII _i

62 A number of administrations and technology proponents have are accordingly conducteding compatibility studies to assess coexistence between HAPS and incumbent and proposed systems and services (including WRC-19 Agenda Items 1.6 and 1.13). The sharing and compatibility studies have been developed on a band-by-band basis as separate new reports. In general, these studies consider the impact of HAPS uplink (ground-to-haps) and/or downlink (HAPS-to-ground) transmissions. In most cases, the studies identify specific methods to ensure the protection of each service. The studies are based on assumptions related to the types of deployment scenarios and technical characteristics of HAPS systems which are described in the draft of a new recommendation on HAPS characteristicsascharacteristics as well as the specific text within each sharing study. WP 5C MAY-JUNE 2018 In May 2018, WP 5C completed the draft CPM text for WRC-19 Agenda Item 1.14, which contains viable methods and regulatory options to facilitate use of broadband applications via HAPS. Section 5 of the report contains draft footnotes, WRC Resolutions and modifications to the Table of Allocations for possible HAPS identifications. The draft CPM text also contains a section that characterizes the status of the studies undertaken and their results, through summaries complete with details of the pfd masks and limits for protecting incumbent services. Formatted: Font: A power-flux density (PFD) limit can be used to ensure the protection of the fixed and mobile services from downlink emissions by HAPS platforms (HAPS-to-ground). This PFD limit ensures that the signal level produced by HAPS systems at the location of fixed and mobile service stations will not cause interference. Protection from uplink emissions by HAPS ground stations could be ensured through coordination at national level, based on the relatively short separation distances (and other mitigation techniques) provided by the studies. The protection of FSS satellite networks on a co-channel basis appears to be feasible if the frequency bands used by a HAPS network is transmitting in an opposite direction from that of the FSS satellite network (i.e., satellite Earth-to-space with HAPS-to-ground, and satellite space-to-earth with ground-to- HAPS). In these cases, some studies suggest that satellite stations can be protected from HAPS-to-ground emissions, while relatively short separation distances can be used to protect Earth stations from groundto-haps emissions through station coordination amongst administrations or usual link planning procedures used at a national level. In this latter case of national level coordination, the use of mitigation techniques and/or geographical separation could be used to enable ubiquitous levels of deployments by either service. For the protection of science services (EESS, SRS, RAS), radiated power limits and coordination amongst administrations could be used to ensure the protection of these services. The protection of these services is most feasible when the direction of HAPS transmission is opposite to the direction of reception of the scientific service (e.g. HAPS-to-ground with EESS passive satellite and ground-to-haps with EESS/SRS earth stations). In the case of science services operating in adjacent bands to HAPS, specific limits on outof-band emissions for both HAPS platforms and ground stations can be used to ensure their protection. Formatted: Font: Not Highlight METHODS Methods to address Agenda Item 1.14 envisage potential global/regional HAPS designation of all existing bands and candidate bands outlined in Resolution 160. This signals that technical studies foresee the CCPII _i

63 feasibility of sharing with other services in all bands with appropriate conditions to protect other services. At its May 2018 meeting, ITU-R WP 5C approved the following methods in the draft CPM text: Method A No change. The existing provisions in the Radio Regulation remain unchanged in the corresponding frequency band. Method B Designation of bands, in accordance with Resolution 160 (WRC-15) with options. This may include, e.g. global or regional designation for HAPS, limitations regarding link directions, and inclusion of the technical conditions of operation of HAPS systems for the protection of other services. This could be achieved by new or revised footnotes to the Table of Frequency Allocations, and new or revised associated WRC Resolutions. Method B1 Revision of the regulatory provisions for HAPS in the fixed service (FS) with a primary status in bands already designated for HAPS. Method B2 Add new designation(s) for HAPS in bands already allocated to the FS with a primary status.

Uruguay Uruguay supports the studies carried out within the framework of Resolution 160 (WRC-15). While these studies demonstrate the feasibility of sharing and compatibility with existing services and do not impose restrictions on their future development, Uruguay supports the adoption of the pertinent regulatory measures, including the eventual need for additional spectrum for HAPS.

67 Agenda Item 1.15: to consider identification of frequency bands for use by administrations for the landmobile and fixed services applications operating in the frequency range GHz, in accordance with Resolution 767 (WRC-15). BACKGROUND Over the past few years, there has been an increasing interest to study the use of frequency bands above 275 GHz for active services. At present, there are no international allocations for radiocommunications services above 275 GHz in the Radio Regulations (RR s). However, footnote No does make identifications for radio astronomy, earth exploration-satellite (passive) and space research (passive) services. Recent advances in microwave technology make possible the use of this spectrum by active services for communications and related uses. Consistent with No , frequencies for fixed and land mobile use could be utilized above 275 GHz, provided all practicable steps are taken to protect passive services. The frequency band GHz is identified for radio astronomy service application, and the frequency bands GHz, GHz and GHz for Earth exploration-satellite service (passive) and space research service (passive) applications. In the frequency range below 275 GHz, the band GHz is allocated to FS, FSS (Earth-to-space), MS and RAS, where No applies. Report ITU-R RA.2189 (2010) Sharing between the radio astronomy service and active services in the frequency range GHz indicates that the radio astronomy service can share with terrestrial systems due to propagation conditions and power limitations of current active services technologies. The space research service (passive) and the Earth exploration-satellite service (passive) may also be able to share frequencies with the active services; however, studies are needed to demonstrate this. ISSUES What are the applications, equipment types and deployment parameters for potential fixed and mobile services use in frequencies above 275 GHz? What is the impact from potential fixed and mobile services use to the protection of passive services identified in GHz (RR No )? DISCUSSION The latest working document towards draft CPM text for WRC-19 agenda item 1.15, is contained in Annex 1 to Doc. 1A/208, the WP 1A Chairman s Report of the June 2017 meeting. WP 1A is developing a working document towards a preliminary draft new Report ITU-R SM.[ GHZ_SHARING] Sharing and compatibility studies between land-mobile, fixed and passive services in the frequency range GHz (Annex 3 to Doc. 1A/208) WP 5A and 5C have developed draft new ITU-R Reports outlining the technical characteristics of mobile and fixed services, respectively, above 275 GHz, which have been approved in ITU-R Study Group 5: - Report ITU-R M.2410 Technical and operational characteristics of the land mobile service applications operating in the frequency range GHz (ex-doc. 5/80): covers close CCPII _i

68 proximity mobile systems operating in the frequency bands GHz and GHz, including description of applications and characteristics of KIOSK downloading mobile systems, ticket gate downloading mobile systems, inter-chip communication systems, intra-device communications, and wireless links for data centers; which are all high-capacity mobile applications over short distances. - Report ITU-R F.2416 Technical and operational characteristics and applications of the point-topoint fixed service applications operating in the frequency band GHz (ex-doc. 5/74): it is noted that the GHz frequency range is already allocated to the fixed service and if the GHz frequency range were to also be identified for the fixed service, a continuous 68 GHz wide band could be formed. CAN Section 6.1 of Report ITU-R F.2416 notes that even though free space path loss increases with frequency, the overall propagation conditions in the range GHz band are similar to the frequency range GHz, thus the range MHz would enable 68 GHz for radio systems capable of fulfilling high capacity transmission. Therefore, this frequency range may be used for outdoor point-to-point fixed service applications over several hundred meters, making it suitable for short distance and very high capacity fixed services as an alternative to wireline backhaul transport applications in dense urban areas. PRELIMINARY VIEWS Canada, United States of America Canada and the United States are of the view that it may be possible to develop a similar footnote to that in No for land-mobile and fixed services, identifying bands for terrestrial active service use. To this end, Canada and the United States support studies in the ITU-R on sharing and compatibility between passive and active services as well as spectrum needs for the land-mobile and fixed services for WRC-19 agenda item 1.15 under the terms of Resolution 767 (WRC-15).

70 Agenda Item 1.16: to consider issues related to wireless access systems, including radio local area networks (WAS/RLAN), in the frequency bands between MHz and MHz, and take the appropriate regulatory actions, including additional spectrum allocations to the mobile service, in accordance with Resolution 239 (WRC-15). BACKGROUND RLANs have proven to be a success in providing affordable and ubiquitous broadband access to the Internet. Introduced by some administrations in the 2.4 GHz band and subsequently expanded into some of the 5 GHz frequency bands, RLANs, specifically Wi-Fi devices, now carry approximately half of all global Internet Protocol (IP) traffic. 5 In fact, mobile carriers have increased their reliance on Wi-Fi offload, voice-over-wi-fi (VoWiFi), and similar technologies. 6 Wi-Fi in the 5 GHz band and elsewhere has also generated billions of dollars of economic value, as well as innumerable consumer benefits. Much of this recent growth reflects a significant increase in the use of 5 GHz bands for RLANs, both to alleviate congestion in the 2.4 GHz band and satisfy consumer demand for higher-speed wireless access. CITEL Recommendation PCC.II/REC. 11(VI-05) recommends the use of the MHz, MHz and MHz frequency ranges by WAS including RLANs. The bands MHz and MHz were made available to the mobile service for the implementation of wireless access systems (WAS) including radio local area networks (RLANs) by WRC-03. Based on studies carried out by the ITU-R, WRC-03 adopted footnote 5.446A and the associated Resolution 229 (Rev. WRC-12) that specifies technical and operational limits on RLANs to ensure compatibility with other services in the same frequency range (e.g.,in the band MHz the Resolution restricts WAS/RLAN implementation to indoor use). In addition, the ITU-R adopted several ITU-R Recommendations 7 dealing with the sharing between the mobile service and other services in the 5 GHz frequency range. The frequency band to MHz was not considered at WRC-03. In the frequency band to MHz there are no primary mobile allocations. Earth explorationsatellite service (EESS) (active) allocations in the frequency bands MHz and MHz are essential for Earth-observation programs and the data these provide is vital for reliable and up-to-date information on how our planet and its climate are changing. In addition, the band MHz is also allocated to the aeronautical radionavigation service (ARNS) and the Radiolocation service on a primary basis. Since 2003, there has been considerable growth in the demand for WAS/RLAN applications with multimedia capabilities; WAS/RLAN also complement licensed commercial mobile networks (i.e., offloading) and fixed wireline networks. As technology evolves to meet increasing performance demands, and traffic on broadband WAS/RLAN increases, the use of wider bandwidth channels in order to support high data rates may create a need for additional spectrum Cisco Systems, Inc., Cisco Visual Networking Index: Global Mobile Data Traffic Forecast Update, , (3 Feb. 2016), Id. at 25. Including Recommendation ITU-R M , Recommendation ITU-R RS.1632, and Recommendation ITU-R M CCPII _i

71 WRC-15 examined the possibility of additional global allocations to the mobile service in the frequency bands MHz and MHz to facilitate contiguous spectrum for WAS/RLAN, thereby enabling the use of wider channel bandwidths to support higher data throughput. The compatibility studies performed by ITU-R in preparation for WRC-15 indicated that when assuming the use of WAS/RLAN mitigation measures limited to the regulatory provisions of Resolution 229 (Rev.WRC-12), sharing between WAS/RLAN and the EESS (active) systems in the frequency bands to MHz would not be feasible, as well as being insufficient to ensure protection of certain radar types in this frequency band. For these cases, sharing may only be feasible if additional WAS/RLAN mitigation measures are implemented. However, no agreement was reached on the applicability of any additional WAS/RLAN mitigation techniques. No studies were also carried out for the frequency band MHz. As such, WRC-15 concluded no change (NoC) for these frequency bands. Nevertheless, considering that adequate and timely availability of spectrum and supporting regulatory provisions are essential to support future growth of WAS/RLAN applications and that harmonized worldwide bands that support future growth of WAS/RLAN applications are highly desirable in order to achieve the benefits of economies of scale, Resolution 239 (WRC-15) resolves to invite the ITU-R to conduct and complete in time for WRC-19: a) to study WAS/RLAN technical characteristics and operational requirements in the 5 GHz frequency range; b) to conduct studies with a view to identify potential WAS/RLAN mitigation techniques to facilitate sharing with incumbent systems in the frequency bands MHz, MHz, MHz and MHz, while ensuring the protection of incumbent services including their current and planned use; c) to perform sharing and compatibility studies between WAS/RLAN applications and incumbent services in the frequency band MHz with the possibility of enabling outdoor WAS/RLAN operations including possible associated conditions; d) to conduct further sharing and compatibility studies between WAS/RLAN applications and incumbent services addressing: i) whether any additional mitigation techniques in the frequency band MHz beyond those analysed in the studies referred to in recognizing a) would provide coexistence between WAS/RLAN systems and EESS (active) and SRS (active) systems; ii) whether any mitigation techniques in the frequency band MHz would provide compatibility between WAS/RLAN systems and radio determination systems; iii) whether the results of studies under points i) and ii) would enable an allocation of the frequency band MHz to the mobile service with a view to accommodating WAS/RLAN use; e) to also conduct detailed sharing and compatibility studies, including mitigation techniques, between WAS/RLAN and incumbent services in the frequency band MHz with a view to enabling a mobile service allocation to accommodate WAS/RLAN use; f) to also conduct detailed sharing and compatibility studies, including mitigation techniques, between WAS/RLAN and incumbent services in the frequency band MHz with a view to accommodating WAS/RLAN use under the existing primary mobile service allocation while not imposing any additional constraints on the existing services, CCPII _i

72 FIGURE 1 Summary of international allocations in the 5 GHz range ITU-R WP5A is the responsible working party for this agenda item. The first WP5A meeting for this study cycle was held from May 10-19, 2016 in Geneva, Switzerland. There are seven output documents related to this agenda item attached to the WP5A Chairman s Report (see Annexes and of Document 5A/114). Liaison statements were also sent to other groups seeking information for sharing and compatibility studies (see Annex 2 of Document 5A/114). ISSUES In the different frequency bands within the 5 GHz range in Resolution 239: Determination of mitigation techniques to protect incumbent primary services (including their current and planned use) from a possible new allocation to the mobile service or potential relaxation of technical and operational restrictions for WAS/RLAN operating in the mobile service. Determination of potential technical and operational restrictions for WAS/RLAN operating in the mobile service to facilitate sharing with systems of incumbent services. Modelling of RLAN deployment, technical and operational characteristics (e.g., LTE-U/LAA not considered during WRC-15) Addressing linkages between WRC-19 agenda item 1.16 and issue regarding updating of reference to the 5 GHz ITU-R Recommendation; and take into account any action in the ITU-R ITS (Intelligent Transport Systems) in the 5 GHz range. The candidate bands MHz for WAS/RLAN are portions of the unplanned bands allocated to Fixed Satellite Services. In Brazil, the frequency bands MHz are used for uplink of the C band and the use of C band is widespread in Brazil. Studies are necessary with the view to ensure protection of the C band uplink and of all existing services in the candidate bands. CCPII _i

73 Some countries in Region 2 authorized RLAN operations that extend beyond current Radio Regulations including: o removing the indoor only restriction and increasing the permitted power for the MHz frequency band; o modifying compliance measures to protect Terminal Doppler Weather Radar (TDWR) and other radars operating in the MHz and MHz frequency bands from harmful interference; o and authorizing RLAN operations in the MHz frequency band. PRELIMINARY VIEWS Brazil The Brazilian Administration supports the necessity for studies to consider possible additional spectrum allocation to be mobile service, including radio local area networks (WAS/RLAN), while ensuring the protection of the C band uplink and of all existing services in the candidate bands. Canada Canada is of the view that only the specific frequency bands MHz, MHz, MHz and MHz listed in the resolves and invites ITU-R of Resolution 239 (WRC-15) are to be considered and/or studied under WRC-19 agenda item 1.16 and not the entire 5 GHz frequency range ( MHz). Canada is assessing and may contribute to studies listed under invites ITU-R of Resolution 239 (WRC- 15). Mexico WAS/RLANs have promoted the development of broadband access and have been deployed licenseexempt, pursuant to the provisions of CITEL and ITU-R, in the frequency bands MHz, MHz, MHz, MHz, and MHz. However, it is considered that a potential additional allocation to the mobile service should be based on evidence of spectrum saturation in existing bands, growth projections, and the non-affectation/degradation of any existing services that might operate in the potential additional spectrum.

75 Agenda item 7: to consider possible changes, and other options, in response to Resolution 86 (Rev. Marrakesh, 2002) of the Plenipotentiary Conference, an advance publication, coordination, notification and recording procedures for frequency assignments pertaining to satellite networks, in accordance with Resolution 86 (Rev.WRC-07) to facilitate rational, efficient, and economical use of radio frequencies and any associated orbits, including the geostationary-satellite orbit BACKGROUND Resolution 86 (Rev. Marrakesh, 2002) requested that the 2003 World Radio Conference (WRC-03) and subsequent Conferences review the regulatory procedures associated with the advance publication of information (API), coordination and notification and recording of satellite network filings. The objective is to simplify the process and provide the BR and administrations with cost savings while maintaining the guiding principles outlined in the Constitution and the Radio Regulations. WRC-03 identified in Resolution 86 (WRC-03) the scope and the criteria to be used for the implementation of Resolution 86 (Rev. Marrakesh, 2002). WRC-07 amended Resolution 86 (WRC-03) to simplify and eliminate redundant elements. Resolution 86 (Rev.WRC-07) invites future Conferences to consider any proposals which deal with deficiencies and improvements in the relevant procedures of the Radio Regulations for frequency assignments pertaining to space services which have either been identified by the Board and included in the Rules of Procedure or which have been identified by administrations or the Radiocommunication Bureau, as appropriate. Future Conferences should ensure that these procedures and the related appendices of the Radio Regulations reflect the latest technologies. ISSUE A - Clarify the concept of bringing into use of frequency assignments for non-gso satellite systems in the Radio Regulations BACKGROUND During WRC-15, there were a lot of discussions with respect to the bringing into use of frequency assignments for non-gso FSS/MSS systems. However, WRC-15 was not able to conclude on any specific provision in the Radio Regulations. As there are an increasing number of Non-GSO FSS/MSS satellite filings within the ITU, there is a need to specify in the Radio Regulations (RR) the requirements for the bringing into use of frequency assignments to a non-gso satellite system to be considered completed. The ITU-R studied both the bringing into use question for non-gso systems, and the possibility of adopting a milestone-based approach to facilitate, in particular, deployment of non-gso satellite systems comprised of multiple, multi-satellite constellations in particular frequency bands. The ITU-R studies have led to two general conclusions, each with multiple options for implementation. First, for bringing into use of frequency assignments to non-gso systems, the conclusion is that BIU should continue to be achieved for frequency assignments for all non-gso systems in all bands and services with the deployment of one or more satellites into a notified orbital plane within seven years of the date of receipt of the API or request for coordination, as applicable. The options for this conclusion are whether the deployment should be for ninety days (as provided for FSS and MSS non-gso systems in the Rule of Procedure for RR No ); for a period of less than ninety days; or for no fixed period. Second, for non-gso systems in specific bands and frequencies, the conclusion is that a milestone-based approach should be established in a new Resolution that allows an additional period beyond seven years for the deployment of the number of orbital planes and the number of satellites per orbital plane contained Formatted: Font: 11 pt Formatted: Font: 11 pt Formatted: Font: 11 pt CCPII _i

76 in the filing with the objective to help ensure that the MIFR entries are reasonably aligned with the number of satellites, orbital planes, and satellites per orbital plane actually deployed in such non-gso systems. For this method, there are several options for the number of milestones, the milestone periods, the required percentage of satellites deployed to satisfy the milestones, the consequences of failing to meet a milestone, and appropriate transitional measures to fairly and equitably subject non-gso systems already brought into use but not fully deployed to the milestone-based approach. The following guiding principles were developed, which advance the efficient, rational and economical use of spectrum and orbital resource and improve the transparency of the deployment of non-gso systems. 1. The BIU process should be separate from any follow-up actions required to maintain the rights and protections for the recorded frequency assignments to non-gso satellite systems. 2. The successful completion of the BIU process for non-gso satellite systems does not require the deployment of all satellites in the system by the end of the regulatory period. 3. Appropriate time should be given to allow the completion of the deployment of non-gso satellite systems. 4. Appropriate transitional measures should be considered to address the implications of any new milestones adopted by WRC The milestone- based approach should be applied to non-gso satellite systems in specific space services in specific frequency bands. 6. Concurrently with the development of a milestone-based approach, methodologies should be developed for the implementation of RR Nos. 9.58, 11.43A, and 11.43B relating to the regulatory treatment of the adjustments to the characteristics of frequency assignments to non-gso satellite systems. 7. The milestone based approach should provide incentives to notifying administrations to deploy satellites in a timely manner, as a failure to meet a given milestone for a system will result in consequences. Formatted: Font: 11 pt Formatted: Font: 11 pt Formatted: Font: 11 pt PRELIMINARY VIEWS CAN Canada is of the view that the current seven-year period mayis not be enough to deploy a mega non- GSO constellation. In trying to address this issue, it is important to adopt a balanced approach, taking into account the financial, technological and planning challenges posed by the multiple launches required to deploy this type of constellation but also the need to prevent any abuse that may lead to spectrum reservation. In this context, a milestone approach appears to be an appropriate solution. As such, Canada supports the seven principles developed by ITU-R WP 4A. Canada is of the view that any options considered under Issue A reflect the following principles: 1. the BIU process should be separate from any milestones established to maintain the rights and protections for the recorded frequency assignments to non-gso satellite system; 2. the successful completion of the BIU process for non-gso satellite systems does not require the deployment of all satellites in the system by the end of the regulatory period; 3. appropriate time should be given to allow the completion of the deployment of non-gso satellites in constellations; 4. appropriate transitional measures should be considered for the non-gso satellite system s BIU prior to WRC-19; 5. the procedures adopted under Issue A should be applied to specific services in specific bands; Formatted: Font: 11 pt Formatted: Normal, Justified, Tab stops: Not at 0" " Formatted: Normal, Justified, Indent: Left: 0", First line: 0", Tab stops: Not at 0.63" CCPII _i

77 6. concurrently, with the development of a milestone-based approach, methodologies should be developed for the implementation of RR Nos. 9.58/11.43A/11.43B relating to the regulatory treatment of the adjustments to the characteristics of frequency assignments to non-gso satellite systems. With respect to principle 2 and consistent with the Rule of Procedure on No , the bringing into use (BIU) of frequency assignments to non-gso satellite systems should be considered successfully completed if, amongst other things, there is at least one non-gso satellite deployed on any of the notified orbital planes. While Appendix 4 specifies several elements to characterize the orbital plane, Canada is of the view that in examining any BIU declaration under No. 13.6, or any other relevant provision of the Radio Regulations, the Radiocommunication Bureau should only consider the altitude, the inclination, and the argument of the perigee (for non-circular orbit) of the satellite. There may be a need to clearly reflect this consideration in the Radio Regulations. Furthermore, some tolerances should be allowed for those orbital characteristics that are considered relevant for a successful BIU. In relation to principle 3, Canada is also of the view that the bringing into use and notification of frequency assignments to a non-gso satellite system within the 7-year regulatory period in accordance with No is a pre-requisite to the application of the milestone process. With respect to principle 4, Canada further believes that transitional measures will be required for non- GSO satellite systems for which frequency assignments have been notified, brought into use in accordance with No and for which the end of the associated seven-year regulatory period occurred prior to the date of entry into force of the final acts of WRC-19 (which is expected to be not earlier than Jan 1, 2021). With respect to principle 5, Canada is of the view that the milestone process should apply to all space services allocated in the following frequency bands: , , , , , , , and GHz. MEX Mexico also supports the studies carried out in WG-4A of the ITU-R, and further believes that commissioning frequency assignments associated with non-gso satellite systems requires considering the deployment of a non-gso satellite constellation at 100%; the seven-year period may not be sufficient in some cases. It is also important to consider the complexity and characteristics of each non-gso satellite network, to have alternatives for commissioning the frequency assignment and registering it (in the MIFR), in addition to achieving greater certainty in the procedures and requirements for this stage and helping to minimize the submission of so-called paper satellites for spectrum reservation. Mexico deems the milestone approach to be an option for the commissioning of frequency assignments associated with satellite constellations of non-gso systems. ISSUE B - Application of the coordination arc approach in some portions of the Ka-band for the determination of the coordination requirements between GSO MSS and FSS networks BACKGROUND CCPII _i

78 Issue B of agenda item 7 of the WRC-19 proposes introducing the coordination arc with a value of 8 degrees as a coordination criterion between the MSS and FSS systems and the MSS systems on the frequency bands of GHz (Earth-space) and GHz (space-earth) in the three Regions, to substitute the existing coordination criterion of ΔT/T> 6%. Bearing in mind that according to the current Radio Regulations, to determine whether RR 9.7 requires coordinating between the FSS vs. FSS satellite networks, a coordination arc of 8º is the criterion applied on the same band of frequencies. Currently, according to the Radio Regulations, to determine whether coordination is required under RR 9.7 on the frequency bands of GHz (Earth-to-space) and GHz (space-earth) in the three Regions, the following criteria are applied: - FSS vs. FSS: 8º coordination arc - FSS vs. MSS: ΔT/T> 6% - MSS vs. MSS: ΔT/T> 6% The study findings show that the earth station terminals used in the MSS and FSS in the Ka band are quite similar. Therefore, it can be assumed that the coordination arc that currently triggers effective, efficient coordination between FSS systems can also be applied to activate coordination between the MSS and FSS systems and the MSS systems. PRELIMINARY VIEWS MEX Mexico supports the ITU-R studies on applying the coordination arc concept to substitute the ΔT/T> 6% criterion when determining the requirements to coordinate the FSS and MSS networks and between the MSS networks in the frequency bands of GHz (Earth-space) and GHz (space-to-earth), while maintaining the possibility for Administrations to request the application of the ΔT/T criterion according to RR ISSUE C1 - Alignment of the wording of 8.13 of the Appendix 30B and No A of Article 11 dealing with modifications to the characteristics of a recorded assignment Formatted: Not Highlight BACKGROUND It is generally recognized that provisions in Appendix 30B relating to coordination and notification were actually written on the model of provisions in Article 9 and 11. In particular, we note that paragraph 8.13 of Article 8 in Appendix 30B is similar to No A except for the use of the word notified instead of recorded although both provisions deal with modifications to frequency assignments in the MIFR. The differences between the two terms was deemed significant enough to create an issue under agenda item 7. In response to this issue, the ITU-R developed [Preliminary draft] CPM Report with a single Method for the alignment of 8.13 of Article 8 in Appendix 30B with No A. PRELIMINARY VIEWS To be developed ISSUE C2 - Modification to Appendix 30B to explicitly allow the possibility to submit the Appendix 4 data elements for frequency assignments for only one of the following blocks/sub-bands, GHz and GHz CCPII _i

79 BACKGROUND To be developed PRELIMINARY VIEWS To be developed ISSUE C3 - Modification to Appendix 30B to prevent an inappropriate use of the existing provisions ( 6.13, 6.14, 6.14bis and 6.15) relating to seeking the assistance of the Bureau for requests made under 6.5 (agreement required from administrations with allotments in the plan, assignments in the List or any pending assignments affected) to requests made under 6.6 (agreement required from administrations which territories are included in the service area of an Appendix 30B satellite network) BACKGROUND Under the current regulatory framework, special sections in the BR IFIC relating to the conversion of an Appendix 30B allotment into an assignment, introduction of an additional system 8 or modification of the characteristics of assignments in the RR Appendix 30B List can contain two types of requirements to seek and obtain the agreement of those administrations whose: allotments in the Appendix 30B or assignments in the Appendix 30B List or those already examined by the Bureau (requirements identified under 6.5 of Appendix 30B) are affected, or territories have been included in the service area of the assignment under consideration (requirements associated with 6.6 of Appendix 30B). Appendix 30B does contain specific provisions for seeking the assistance of the Bureau ( 6.13) with associated consequences ( 6.14 to 6.15) in absence of a response to letters from the Bureau for requirements identified under 6.5 of Appendix 30B. However, it is not the case for requirements associated with 6.6 of Appendix 30B. In fact, in this case, the assistance of the Bureau can only be sought through the generic provision, No with no associated consequence in absence of a response to the Bureau s correspondences. Some administrations wanted to reinforce the fact that none of the consequences ( 6.14 to 6.15) associated with an absence of response to a correspondence from the Bureau initiated under PRELIMINARY VIEWS CAN Canada is of the view that the only procedure applicable for seeking the assistance of the Bureau in the case of requests for the inclusion of the territory of an administration within the service area of an Appendix 30B satellite network is provided in No We also note that an absence of response to correspondences from the Bureau initiated under No for this type of request cannot be considered as an implicit agreement to be included in the service area. In this context, Canada is not convinced of the need to modify Appendix 30B and does not support the modification of 6.10 in article 6 of Appendix 30B. ISSUE C4: Allowing a single notice for submission under and 5.1.1/ Formatted: Font: 11 pt 8 See 2.6 of Appendix 30B. CCPII _i

80 BACKGROUND Normally, at the end of the coordination process for Regions 1 and 3 under Article 4 of RR Appendices 30 and 30A and when a network is about to be implemented, systems are submitted for entry into the List under and for Notification under and of RR Appendices 30 and 30A, respectively at the same time. This is logical since both these two provisions refer to actions following the completion of the coordination process and since they are both required to implement the network. It would therefore reduce the workload of both administrations and the Bureau if one physical submission could be treated as, and examined in respect of both these provisions. In respect of RR Appendix 30A, it would seem that this would be in particular of value for notification of receiving space stations and typical earth stations while specific earth stations probably in many cases would be subject to separate notices as the requirements change with time. Looking at the RR Appendix 4 information required for submission under and 5.1.1/5.1.2, these would seem to be identical for entry into the List and notification. The data requirements of RR Appendix 4 therefore should not create any practical difficulties in achieving this goal. PRELIMINARY VIEWS MEX Since this issue deals with procedures that apply only to Regions 1 and 3, the Mexican Administration considers that this issue should not impact Region 2 Plans. Therefore Issue C4 should be limited to Regions 1 and 3.

However, there is no reminder sent by the Bureau during the six-month period. Consideration has been given to requiring the Bureau to send a reminder. PRELIMINARY VIEWS B, CAN These administrations support adding to the relevant provision of Article 11 the obligation for the Bureau to send a reminder to notifying administrations before the end of the six-month period provided in No for the resubmission of notice initially returned by the Bureau without a change to its original date of receipt. CCPII _i

81 ISSUE C6 - Modification to Appendix 30B to allow a simultaneous submission of the Appendix 4 data elements for the purposes of entering the frequency assignments in the List ( 6.17) and recording them ( 8.1) BACKGROUND Under the current satellite regulatory framework, the request by a notifying administration to have its new or modified assignments entered into the Appendix 30B List and the request to have them recorded in the MIFR are done through two different submissions to the Bureau. The ITU-R investigates the possibility to allow the submission of a single request to the Bureau for both entering into the Appendix 30B List and into the MIFR. PRELIMINARY VIEWS B, CAN These administrations support allowing notifying administrations to submit simultaneously the Appendix 4 data elements for the purposes of entering the frequency assignments in the List ( 6.17) and recording these frequency assignments ( 8.1). MEX The administration of Mexico is the opinion that administrations, who wish to register their satellite system under provision 6.17 of Appendix 30B, as well as notify it under provision 8.1 of the same Appendix, could send a single request valid for both provisions. ISSUE C7: Obtaining agreement for a specified period under Article 6 of RR Appendix 30B. BACKGROUND: An agreement between the administrations concerned would facilitate the tasks of administrations applying Article 4, Appendices 30 and 30A, and Article 6, Appendix 30B of the RR. We believe that it would be feasible to implement the possibility of obtaining an agreement from the administrations concerned during a specified time period, thereby considerably facilitating the tasks of administrations applying Article 6, Appendix 30B of the RR. PRELIMINARY VIEW MEX The Mexican administration agrees with the proposal of the ITU-R that proposes a single method for modifying the RR, in which provision 6.15 bis is added to Article 6, Appendix 30B of the RR, to harmonized it with Appendices 30 and 30A for Regions 1, 3 and 2. ISSUE D - Bureau identification and publication of specific satellite networks or systems to be considered when effecting coordination under Nos. 9.12, 9.12A and 9.13 as appropriate CCPII _i

82 BACKGROUND Under the current satellite regulatory framework, the Bureau identifies potentially affected administrations but not the potentially affected satellite networks or systems for coordination under Nos. 9.12, 9.12A and As a result, The ITU-R investigates whether the burden currently borne by administrations may be eased by extending the existing requirement to publish a list of satellite networks or systems as for coordination under Nos. 9.7 and 9.7A. PRELIMINARY VIEWS B, CAN These administrations support extending the current Bureau identification and publication of the satellite networks or systems to be considered when effecting coordination under No. 9.7 and 9.7A to other types of coordination, namely coordination under No. 9.12, 9.12A or 9.13 as appropriate. ISSUE E - Resolution related to RR Appendix 30B Harmonization of RR Appendix 30B with RR Appendices 30 and 30A BACKGROUND Issue M was agreed during the 5 th meeting of WP 4A in February 2018 as possible alternative solution to address the concern for the ability of administrations having no network in the RR Appendix 30B List to convert their national allotments into assignments. In discussing issues E and F in the aforementioned 5 th meeting of WP 4A in February 2018 it was agreed that, instead of pursuing Issues E and F, to establish Issue M as a solution, which more directly addresses the underlying issue; a method based on a WRC Resolution with a special procedure to facilitate coordination of a submission from administrations not having any networks in the Appendix 30B List or under coordination (Annex 45 to the Chairman s Report 4A/675). This Resolution includes procedures for applications for conversion of the allotment of an administration into assignment with changes which are outside the envelope of the initial allotment or for submission by an administration of an additional system while restricted to national service and coverage area. Elements of this procedure include provisions that can be applied only once by an administration having no network in the Appendix 30B List or under coordination, and only for a submission with national service and coverage area. In respect of networks in the List, not entered under this special procedure, administrations making submissions under this special procedure will enjoy relaxed protection criteria: Adopting the structure decided by WRC-2000 for RR Appendices 30 and 30A and by WRC-12 for BSS in the GHz band, i.e. a coordination arc, hard limits (Annex 3 of Appendix 30B) to protect networks outside the coordination arc and mechanisms to remove unnecessary coordination requirements inside the coordination arc. Introducing pfd masks and levels like in RR Appendices 30 and 30A as well as in portions of the unplanned bands to remove unnecessary coordination, avoiding combinations of technical parameters leading to unrealistic links which hinders introduction of new networks. Proposed values for pfd masks and levels are those developed in preparation for WRC-15 Issue 9.1.2, but based on a level of protection corresponding to ΔT/T 12% instead of the usual 6% (for C-band antenna diameters between 1.2 and 18 m and Ku-band antenna diameters between 45 cm and 11 m). CCPII _i

83 Single entry C/I criteria relaxed by 3 db compared to the regular coordination triggers. PRELIMINARY VIEWS CAN Canada is of the view that the specifics of the Region 2 Plan for BSS and its associated feeder links should be maintained. B. Brazil supports the WP 4A agreement to pursue an alternative solution that more directly addresses the underlying concern for administrations having no network in the RR Appendix 30B List, to allow these administrations to convert their national allotments into assignments, on the conditions that issues E and F are suppressed. ISSUE F - Measures to facilitate entering new assignments into the RR Appendix 30B List Concerns with the lack of implementation of certain provisions of the Radio Regulations that can lead to difficulties during the process of entering an assignment into the RR Appendix 30B list BACKGROUND Article 44 of the ITU Constitution stipulates that, for the countries to have equitable access to orbit/spectrum resources, the administrations shall limit their use to the required minimum to provide services satisfactorily and shall endeavor to apply the latest technical breakthroughs. An administration that wishes to convert, in an economically viable way, its national RR Appendix 30B allotment into an allocation very often needs to modify the initial characteristics of its allotments, bearing in mind the latest development available and the breakthrough in technology. For this purpose, the administration shall make a filing and follow the procedures under Article 6 of RR Appendix 30B. An administration that wishes to convert its RR Appendix 30B allotment into an allocation with characteristics beyond what was initially allotted or that wishes to introduce a new network, shall encounter various difficulties, as indicated below: because of the conservative criteria used in RR Appendix 30B, a large amount of coordination requirements shall be identified; the networks can be designed with combinations of characteristics, possibly not very realistic, to secure high sensitivity to interference from later transmissions. Although the structure of the protection criteria for the satellite networks submitted in the unplanned bands and in RR Appendices 30 and 30A, it has undergone major modifications to take into account the technological breakthroughs over the past decades, the structure used in RR Appendix 30B has not changed. In addition, with the protection criteria structure from RR Appendix 30B, if, for example, the parameters of the satellite networks submitted contain small antennas of receiving earth stations with low noise temperatures from the system combined with a low effective isotropically radiated power (EIRP) or highgain receiving space station antennas with global coverage combined with an uplink EIRP, these CCPII _i

84 additional systems/uses shall be very sensitive to interference and overprotected. This may hamper successful coordination of subsequent submittals. PRELIMINARY VIEWS MEX Mexico supports ITU-R studies to update the Appendix 30B coordination triggers, considering the new technological breakthroughs in these systems and to ensure the protection of existing and future networks. ISSUE G - Updating the reference situation for networks under RR Appendices 30 and 30A when provisional recording is used BACKGROUND of Appendices 30 and 30A of the Radio Regulations prescribes that in the case of recording of broadcasting-satellite service (BSS) and associated feeder link assignments in the Regions 1 and 3 List with outstanding coordination requirements this recording shall be provisional. The entry shall be changed from provisional to a definitive recording in the List if the Bureau is informed that the new assignment in the Regions 1 and 3 List has been in use, together with the assignment which was the basis for the disagreement, for at least four months without any complaint of harmful interference being made. When the provisional recording becomes definitive, the reference situation of the interfered-with network will be updated. This could severely affect the reference situation of the interfered-with network. In preparations for WRC-15, this issue was brought to the attention of RRB-70 meeting in October 2015 (Document RRB-70/10), requesting that a Rule of Procedure be prepared to outline the desired practice to be followed by the Bureau. RRB-70 however was of the view that such a RoP would result in a change of the Radio Regulations and therefore was outside the authority of the RRB. WRC-15 decided, then, that.it was felt that further study of this issue is required if this current practice is to be changed. ITU-R is therefore invited to study this issue under the standing agenda item 7 with the aim of finding an appropriate regulatory and technical solution to this issue. Issue G is in response to these activities and to the decision of WRC-15. The corresponding provisions for the Region 2 BSS and associated feeder link Plans are in A of Appendices 30 and 30A. There are a number of differences in Appendices 30 and 30A for Region 2 as compared to Regions 1 and 3. One significant difference is the existence of a List in Regions 1 and 3; modifications or new assignments become part of a separate List, not part of the Regions 1 and 3 Plan itself. In Region 2, modifications actually become a part of the Plan (and hence enjoy the same status as the Plan) and not a separate List. Similarly, there are notable differences between the application of the procedures A for the Region 2 BSS and feeder-link Plans and the application of for the Regions 1 and 3 List. For example, for Regions 1 and 3, may be applied to List assignments and pending modifications to the List, while in Region 2, A is applied in a much more limited fashion, solely to terrestrial services or fixed-satellite service (FSS) or unplanned BSS systems serving another Region. As a result, the concerns that led to Issue G in Regions 1 and 3 concern with degrading a List assignment s reference situation do not exist in Region 2, as A cannot be applied to BSS Plan assignments, modifications to the Plan or pending modifications to the Plan. As a result, the issue is somewhat academic in Region 2 and no change is needed to the Radio Regulations. PRELIMINARY VIEWS CCPII _i

85 B, CAN, MEX These administrations are of the view that the specifics of the Region 2 Plan for BSS and its associated feeder links should be maintained, thus, no modification to A of Appendices 30 and 30A is needed. There are notable differences between the application of the procedures A for the Region 2 BSS and feeder-link Plans and the application of for the Regions 1 and 3 List. Therefore Issue G should be limited to Regions 1 and 3. ISSUES H and I - Modifications to the Appendix 4 data elements to be provided in filings for non- GSO satellite networks/systems BACKGROUND The RR Appendix 4 data elements provided in the Advance Publication Information (API) or the Coordination Request (CR/C) for satellite networks or systems are used initially by administrations to identify potential interference scenarios to their existing and planned systems and to formulate their comments under No. 9.3 or No as appropriate. Recent analysis performed for frequency assignments to NGSO satellite networks or systems has shown that in some instances, there is a need for additional information to accomplish these tasks. Formatted: Not Highlight The RR Appendix 4 data elements provided in the Advance Publication Information (API) or the Coordination Request (CR/C) for satellite networks or systems are used initially by administrations to identify potential interference scenarios to their existing and planned systems and to formulate their comments under No. 9.3 or No as appropriate. Recent analysis performed for frequency assignments to NGSO satellite networks or systems has shown that in some instances, there is a need for additional information to accomplish these tasks. With respect to frequency assignments associated with non-geostationary (non-gso) satellite networks or systems in bands not subject to coordination under Section II of Article 9, the elements of Appendix 4 filed in the API are used by different Administrations to identify possible scenarios of interference to their existing and planned systems. However, identifying such scenarios depends, among other things, on whether the satellite orbits can be modeled adequately based on the data provided in the API. Modeling the satellite orbit of non-gso systems requires much more data than a GSO satellite network. Recent analyzes conducted for non-gso satellite networks or systems based on the API data published by the Radiocommunication Bureau in the International Frequency Information Circular (BR IFIC) have shown that, in some cases, additional data is needed to adequately model satellite orbits. PRELIMINARY VIEWS CAN Issue I For NGSO systems with multiple orbital planes Canada supports the addition of the following data elements in Appendix 4 for frequency assignments to non-gso satellite systems with multiple planes and multiple satellites: -number of configurations for the non-gso satellite systems described in the API or the CR/C as appropriate; -identification of orbital planes associated with each configuration identified above. Formatted: Font: Canada supports also the addition of the following data elements in Appendix 4 for frequency assignments to non-gso satellite service not subject to section II of Article 9: CCPII _i

86 -For elliptical orbit, the argument of the perigee; -For constellation, the angular separation between two consecutive ascending nodes, the angular separation between two consecutive satellites in the same orbital plane, both angles measured from the centre of the Earth, and the angular separation between two satellites in two adjacent planes measured from the centre of the Earth in the ascending direction. MEX Mexico supports the ITU-R studies to identify the information required when filing an API for non-gso systems not subject to the procedures of Section II of RR Article 9, which enables Administrations to identify possible interference scenarios, taking into account the flexibility that may be required for non- GSO satellites with short duration missions and satellites for scientific or experimental purposes. ISSUE I: Additional data elements of RR Appendix 4 for NGSO systems with multiple orbital planes BACKGROUND WRC-15 supported the Director's recommendation to allow two types of Coordination Request (CR/C) filings for frequency assignments to non-gso satellite systems: CR/C for frequency assignments to a non-gso satellite system with one (or more) sets of orbital characteristics, indicating that all system frequency assignments would work simultaneously; CR/C for frequency assignments to a non-gso satellite system with different sets of orbital characteristics, indicating that the different sets of orbital planes would be mutually exclusive, i.e., that the satellites in these sets of orbits would not work simultaneously and only one of them would implement sets of orbital planes. However, RR Appendix 4 was not amended to ensure proper identification of the CR/C type, which led the Bureau to systematically seek clarifications from notifying administrations when submitting a CR/C for frequency assignments to the non-gso satellite system with multiple orbital planes. Although WRC-15 did not specifically address the case of frequency assignments to non-gso satellite systems with multiple planes in bands not subject to coordination under Article 9 of RR Section II, it is important to consider the same level of flexibility for API filings and make RR Appendix 4 reflect this. In current practice, the Bureau requests this information of the notifying administration via letters after receiving an API or a CR/C filing with multiple orbital planes. PRELIMINARY VIEW CAN Canada supports the addition of the following data elements in Appendix 4 for frequency assignments to non-gso satellite systems with multiple planes and multiple satellites: -number of configurations for the non-gso satellite systems described in the API or the CR/C as appropriate; -identification of orbital planes associated with each configuration identified above. CCPII _i

87 MEX Mexico supports the completion and conclusion of ITU-R studies to provide information on the characteristics of non-gso satellite systems with multiple orbital planes and associated settings by filing the API or CR/C as appropriate, and identifying the modifications of RR Appendix 4 that enable identification of the types of coordination requests. ISSUE J: Limit of pfd in Section 1, Annex 1 to Appendix 30 of the RR BACKGROUND Issue J deals with the possibility that the power flux-density (pfd) for broadcasting-satellite networks of the List shall exceed its limit. To provide broadcasting-satellite services, such as UHDTV (see Rec. ITU- R BT.2020), it is necessary to have a highly spectral efficient modulations performance (for example APSK) and a high C/N (carrier-to-noise ratio) requirement (see Rec. ITU-R BO.2098 and Rep. ITU-R BO.2397). In that situation, what is required is a pfd value that exceeds the limit of db (W/(m2 27 MHz)) described in Section 1, Annex 1 of Appendix 30 of the RR, which is necessary inside the service area to achieve the same availability of service as the conventional broadcasting-satellite service. The pfd limit of -103,6 db (W/(m2 27 MHz)) was established for additional use in Regions 1 and 3 in order to protect the BSS networks outside the coordination arc of ± 9 degrees. If an Administration implements the relevant provisions of Article 23 of the RR to request the exclusion of its territory from the BSS network service area of other Administrations, these BSS networks of other Administrations are not entitled to be protected in the territory of the Administration making the objection; the pfd limit of - 103,6 db (W/(m2 27 MHz)) can only be exceeded in the national territory of the notifying Administration, as long as in the border areas and in another territory of another country, this pfd limit is not exceeded. PRELIMINARY VIEW MEX Mexico supports conducting and concluding the ITU-R studies to ascertain if it is possible to exceed the power flux-density (pfd) limit in the territory of a notifying Administration of a network, taking into consideration the protection of border areas, the territory of other Administrations, and BSS allocations. ISSUE K: Difficulties for Part B examination under or of RR Appendices 30 and 30A and under 6.21 c) of RR Appendix 30B BACKGROUND To address the difficulties encountered by the notifying administration in the Part B examination of its junior network (herein after referred to as Network JR ) under RR Appendices 30 and 30A or or under RR Appendix 30B 6.21 c), it is proposed to add one more examination under or of RR Appendices 30 and 30A and under 6.21 c) of RR Appendix 30B such that, should any remaining affected networks whose assignments have been entered in the List or Plan, as appropriate, before the submission under or of RR Appendices 30 and 30A or under 6.17 of RR CCPII _i

88 Appendix 30B, the Bureau shall further examine if the remaining corresponding assignments in the List or Plan are still considered as being affected. In this way, like the current practice today, if examination under or of RR Appendices 30 and 30A or under 6.21 c) of RR Appendix 30B of Part B of a junior network (hereinafter referred to as Network JR-Part B ) in respect of Part A of a senior network (hereinafter referred to as Network SR- Part A ) is favorable, the senior network (hereinafter referred to as Network SR ) is considered as NOT being affected like today and no further examination will be conducted. Meanwhile, it addresses the difficulties experienced by the notifying Administration and allows its notice submitted under or of RR Appendices 30 and 30A or under 6.17 of RR Appendix 30B (Network JR-Part B) to receive favorable findings in respect of Network SR if Network SR-Part B is considered as not affected in the further examination based on the method of Annex 1 (Appendix 30), Annex 1 (Appendix 30A) or Annex 4 (Appendix 30B); this shall avoid overprotection of Network SR based on the characteristics which are outdated and no longer valid while ensuring Network SR is adequately protected. PRELIMINARY VIEW MEX Mexico supports ITU-R studies in order to determine an additional examination to identify and address the difficulties encountered by the notifying Administrations in the practice of notifying the networks, which shall keep the affected networks up-to-date and thus guarantee adequate protection. ISSUE L: Updating data elements of Appendix 4 needed to validate the EPFD of RR Article 22 after revision of ITU-R Recommendation S.1503 BACKGROUND It is proposed that there should be a revision of the data elements required for validating the equivalent power flux density (EPFD) of RR Article 22 as a result of the revision of ITU-R Recommendation S At the meeting of Radiocommunications Study Group 4 held on October 27, 2017, the Group decided to request the adoption of revised ITU-R Recommendation S Functional description to be used in developing software tools for determining conformity of non-geostationary-satellite orbit fixed-satellite system networks with limits contained in Article 22 of the Radio Regulations. Revised recommendation ITU-R S was adopted on January 2018 after the simultaneous adoption and approval procedure by correspondence. Recommendation ITU-R S.1503 defines an algorithm that can be used to ascertain whether or not a nongeostationary-satellite orbit (NGSO) fixed-satellite system (FSS) complies with the EPFD limits indicated in RR Article 22. A revision of this Recommendation led to ITU-R S and to ITU-R S approved at the Study Group 4 meeting in October The revised version introduced greater flexibility so that the operators of NGSO systems would model their network while guaranteeing that the core algorithm to calculate EPFD statistics would remain virtually unchanged. This greater flexibility comes, in part, from the new input parameters and, in part, from the additional dimensions to existing input parameters. For example, it was assumed that the angle CCPII _i

89 of the exclusion area would be a single value in Recommendation ITU-R S , but in the revision it can vary depending on the latitude and frequency band. To obtain these benefits, it is necessary for the input data to be available; and to guarantee that this does occur, they must be mandatory parameters defined in RR Appendix 4. Therefore, it is proposed that RR Appendix 4 be revised to include these additional parameters. PRELIMINARY VIEW MEX Mexico supports ITU-R studies on RR Article 22 in accordance with the revision implemented in ITU-R Recommendation S.1503 and thus determine the additional parameters that must be included in RR Appendix 4 so that both can be consistent.

91 Agenda item 9.1, issue 9.1.1: to study possible technical and operational measures to ensure coexistence and compatibility between the terrestrial component of IMT (in the mobile service) and the satellite component of IMT (in the mobile service and the mobile-satellite service) in the frequency bands MHz and MHz where those frequency bands are shared by the mobile service and the mobile-satellite service in different countries, in particular for the deployment of independent satellite and terrestrial components of IMT and to facilitate development of both the satellite and terrestrial components of IMT. BACKGROUND The frequency bands MHz and MHz (total of 230 MHz) were the very first identified for IMT at WARC Of these frequency bands, the bands MHz and MHz were also to be used for the satellite component of IMT, in No and under the provisions of Resolution 212 (Rev. WRC-15). Resolution 212 (Rev. WRC-15) notes that the terrestrial component of IMT (e.g. LTE) has either been deployed or is currently being considered for deployment globally in the frequency bands MHz, MHz and MHz. It further notes that both the terrestrial and satellite IMT have either been deployed or are planned for deployment in the bands MHz and MHz. In addition, Resolution 212 (Rev. WRC-15) reiterates that the attractiveness of IMT can be improved by making this 60 MHz spectrum available to both the terrestrial and satellite components of IMT. Resolution 212 (Rev. WRC-15) further notes that it is not feasible to implement the terrestrial and satellite components of IMT on the same frequency and in the same geographical area is not feasible unless techniques such as use of an appropriate guard band or other mitigation techniques are applied to ensure the coexistence and compatibility of the terrestrial and satellite components of IMT. Finally, it invites the ITU-R to study possible technical and operational measures to ensure coexistence and compatibility between MS in one country and MSS in another country. ITU-R WP 5D is responsible for the studies related to the protection of the terrestrial component of IMT, taking into account the technical and operational characteristics of satellite systems provided by ITU-R WP 4C. Similarly, the ITU-R WP 4C is responsible for the studies related to the protection of the satellite component of IMT, taking into account the technical and operational characteristics of terrestrial IMT systems provided by ITU-R WP 5D. An ITU-R report or recommendation will be prepared based on the studies. CPM text will be jointly developed by these two working parties. The bands MHz and MHz overlap with parts of existing commercial mobile bands in some countries in the frequency ranges / MHz, / MHz and / MHz (see ITU-R Recommendation M.1036), in which terrestrial IMT systems exist or are expected to be deployed. The band / MHz is also licensed for MSS use in some countries. CITEL PCC.II has conducted a survey entitled Request for information about the current and planned use of the bands MHz and MHz by the OAS/CITEL administrations for terrestrial and satellite services in February 2015 (see Decision PCC.II/DEC. 173 (XXV-15) in CCP.II-RADIO/doc. 3857/15 rev.1) 9, which may be relevant for the studies under this issue. 9 The responses from different Administrations received to-date are available in CCP.II-RADIO/doc. 3988/15 rev.1 (Argentina, Brazil, Canada, Costa Rica, Ecuador, Guatemala, Jamaica, Panama and Nicaragua) and CCP.II- RADIO/doc. 4054/16 (Colombia). CCPII _i

92 Also, CITEL adopted a recommendation on the frequency arrangement for the use of the / MHz band for broadband mobile services, recommending CITEL administrations that plan to use this spectrum do so by adding additional contiguous bandwidth as an expansion of the existing bands in the / MHz or / MHz in some countries (see Decision PCC.II/REC. 43 (XXIII-14) in CCP.II-RADIO/doc.3597 /14 rev.1). ISSUES Determination of appropriate technical and operational measures from the studies being conducted within ITU-R to ensure coexistence and compatibility between the terrestrial component of IMT (in the mobile service) in one country and the satellite component of IMT (in the mobile-satellite service) in another country in the frequency bands MHz and MHz. PRELIMINARY VIEWS Canada There should not be any impact from the outcome of these studies on the existing use of the frequency bands by the terrestrial component of IMT in MHz (part of the / MHz IMT frequency band) nor on flexible MS/MSS use in & MHz. Mexico For the administration of Mexico, it is important to know the final outcomes of these studies of the abovementioned Working Parties, since the bands / MHz and / MHz are designated for the terrestrial component of IMT in Mexico. The segmentation specified for these bands is based on an FDD scheme in which the MHz and MHz segments are used for base-mobile transmission and the MHz and MHz segments are used for basemobile transmission. In addition, Mexico is authorized to exploit the emission and reception rights of signals and frequency bands associated with foreign satellite systems that cover and can provide services within its national territory at the / MHz frequency band. Accordingly, if the MHz and MHz frequency bands were used for the satellite component of IMT in a country with which Mexico shares borders, it would be necessary to set out the technical and operational measures to ensure coexistence and compatibility between the two IMT components. Stemming from the above, the administration of Mexico supports the studies that are being conducted in ITU-R Working Parties 4C and 5D on the coexistence and compatibility between the satellite component of the IMTs (in the mobile-satellite service) and the terrestrial component of the IMTs (in the mobile service) in the bands and MHz, when these systems are implemented in different countries. The administration of Mexico supports not changing the Radio Regulations in the allocations and in the regulatory framework associated with these frequency bands. Finally, the administration of Mexico considers that, on the basis of the outcomes of the studies that are being conducted in ITU-R Working Parties 4C and 5D, it is possible that actions must be undertaken to mitigate possible problems of interference arising from the use of both components of the IMTs in the frequency bands MHz and ,200 MHz. USA Support studies of technical and operational measures under agenda item 9.1/issue in accordance CCPII _i

93 with Resolution 212 (Rev. WRC-15), with the objective of ensuring compatible operations of both the terrestrial component of IMT in the mobile service and the satellite component of IMT in the mobilesatellite service in neighboring countries, without undue constraints on either service, in the frequency bands MHz and MHz.

97 Agenda Item 9.1, Issue Study of technical and operational issues and regulatory provisions for new non-geostationary-satellite orbit systems in the MHz, MHz, MHz and MHz frequency bands allocated to the fixed-satellite service BACKGROUND Source Document CCP.II Punta Cana - CAN The Report of the Director of the Radiocommunication Bureau to WRC-15 acknowledged that there may be a need for reviewing or confirming assumptions that led to the development of the power limits found in Article 21 and Article 22, taking into account the characteristics of non-gso systems recently submitted to the ITU-R. Moreover, given the growing interest in deploying non-gso FSS systems, the Report of the Director of the BR noted that there is a need to ensure that all existing services are adequately protected. As a result, WRC-15 adopted Resolution 157 (WRC-15), which discusses how facilitating the deployment of new types of non-gso systems has the potential to augment the capacity, spectrum efficiency and benefits derived from GSO and non-gso systems operating in the bands MHz (space-to-earth), MHz (space-to-earth), MHz (Earth-to-space), MHz (Earth-to-space). There are approximately 170 GSO satellites currently operating in the MHz band and 229 allotments in the MHz band, both of which are globally allocated to provide C-Band FSS downlinks. Many highly sensitive and public services use the FSS C-band, such as satellite telemetry, disaster relief, public meteorological data distribution, and aeronautical applications in various regions. A number of next-generation NGSO systems are being developed that can provide high-capacity, lowlatency communications to end users in all locations around the world, thus allowing those living and working in rural and remote areas to access the same level of connectivity as those living in more densely populated urban areas. Resolution 157 (WRC-15) also contains a list of technical and operational issues (e.g. Article 21 and 22) to be studied for the bands identified above; requests the development of new regulatory provisions for the protection of terrestrial services in the band MHz and non-gso MSS feeder links receiving stations in the band MHz; and the clarification of some existing regulatory provisions (e.g A and 5.457C). Source Document CCP.II Bogota - Brasil Article 21 and Article 22 of the Radio Regulations contain provisions to ensure compatibility of non-gso FSS operations with terrestrial stations and GSO networks, respectively. Among these provisions, Article 21 contain power flux-density (pfd) limits to protect terrestrial stations and Article 22 contain equivalent power flux-density (epfd ) limits in the frequency band MHz (space-to-earth) and epfd limits in the frequency band MHz (Earth-to-space) to protect GSO networks from unacceptable interference pursuant to RR No The development of current regulatory provisions for sharing between non-gso FSS operations with GSO networks in the 6/4 GHz bands was based on using highly-elliptical orbits (HEO). Based on the unique orbital configuration of the HEO systems, Article 22 epfd limits are more stringent than epfd limits in other FSS bands where non-gso using circular orbits was taken into account. WRC-19 issue calls for reviewing Article 21 power flux-density (pfd) limits and Article 22 equivalent power flux- CCPII _i

98 density (epfd ) limits applicable to non-gso systems operating in the MHz, MHz, MHz and MHz frequency bands taking into account the characteristics of potential new non-gso FSS operations, with the view to ensure protection of all existing services, since non-gso FSS systems are obligated by No of the Radio Regulations not to cause unacceptable interference to or claim protection from GSO FSS networks. Resolution 157 (WRC-15) calls to study technical and operational issues and regulatory provisions for these non-gso FSS operations. ISSUES Source Document CCP.II Punta Cana - CAN Under the current regulatory framework, the use of the bands MHz and by non- GSO FSS systems is allowed subject to regulatory measures such as Article 22 EPFD limits and Article 21 PFD limits developed to protect GSO FSS systems and terrestrial services, respectively, from a specific type of non-gso FSS systems (HEO systems). These measures may not be suitable for other types of non-gso FSS systems, noting further resolves 1 which states that the results of studies shall in no way change the protection criteria and protection levels defined in those criteria for the GSO FSS, the fixed service and the mobile service. Under the current regulatory framework, the use of the bands MHz (space-to-earth) and MHz (Earth-to-space) by the fixed satellite service shall be in accordance with the provisions of Appendix 30B, which is limited to the geostationary-satellite of the fixedsatellite service as per No Under the current regulatory framework, the protection of the non-gso MSS feeder link receiving earth station in the band MHz is ensured through the application of coordination procedures under No. 9.17A (see also Table 9a in Appendix 7). As already indicated above, the use of the band MHz by non-gso FSS in the earth-to-space direction is not allowed as per No Source Document CCP.II Bogota - Brazil Traditionally, the C-band has had limited opportunities for sharing between non-gso FSS operations with GSO networks, given the wider antenna beams and poorer off-axis discrimination. However, it is important to emphasize that the use of MHz ( C band ) is widespread in Brazil due to its climate characteristics, associated with its continental dimensions and the lack of telecommunications infrastructure in several parts of the Country. In these bands, uplink signals are operating in thousands of land stations associated with networks that provide crucial services for public institutions (public law enforcement and security, natural disasters, social programs for distance learning, electronic government services, etc.) which bring benefits to millions of citizens. These bands are also used by operators of commercial public networks (DTH, Internet, VOIP, backhaul of mobile telephony) with millions of private users. It will be important to conduct the necessary studies including the development of the epfd mask for the potential new non-gso FSS operations to determine the sharing potential between non-gso FSS operations with GSO networks as well as, other incumbents in this band while ensuring the protection of existing services in this band. CCPII _i

99 PRELIMINARY VIEW CAN Source Document CCP.II Punta Cana CAN Canada supports the studies under Resolution 157 (WRC-15) for new non-gso FSS satellite systems. Any modification to Article 22 for the inclusion of epfd limits for non-gso FSS systems in the bands MHz (space-to-earth) and MHz (Earth-to-space) to protect the geostationary FSS allotments in the Plan and the assignments in the Appendix 30B List can only be considered in conjunction with modifications to Article 5, including No to authorize use of these bands by non- GSO FSS systems. This footnote specifies that the use of the bands by the FSS shall be in accordance with Appendix 30B, which is limited to the geostationary-satellite of the fixed-satellite service. This is not the case in the bands MHz and MHz where non-gso FSS are currently allowed without any restrictions in Article 5. Similarly, the adoption of regulatory measures to protect terrestrial services in the band MHz (space-to-earth) can only be considered in conjunction with modifications to No Canada also notes that under the current regulatory framework, the protection of the non-gso MSS feeder link receiving earth station from non-gso FSS transmitting earth station in the band MHz and MHz is ensured through the application of coordination procedures under No. 9.17A (see also Table 9a in Appendix 7). An extension of these coordination procedures to the band MHz can only be achieved through modifications to No referred to above. B Source Document CCP.II Bogota - Brasil The Brazilian Administration is of the view that studies are necessary to ensure that the protection of GSO networks would not be reduced beyond that currently afforded by Article 22 epfd limits.

101 Agenda Item 9: to consider and approve the Report of the Director of the Radiocommunication Bureau, in accordance with Article 7 of the Convention: Agenda Item 9.1: on the activities of the Radiocommunication Sector since WRC-15. Note: The subdivision of Agenda Item 9.1 into issues, such as 9.1.1, 9.1.2, etc., was made at the first session of the Conference Preparatory Meeting for WRC-19 (CPM19-1) and is summarized in the BR Administrative Circular CA/226, 23 rd December Agenda Item 9.1.4: to determine spectrum requirements for sub-orbital vehicles (space planes) and, based on the outcome of those studies, to consider a possible future agenda item for WRC-23 BACKGROUND Advances in propulsion technology and rocket power has facilitated the design of vehicles which may reach altitudes greater than 100 km, also known as sub-orbital flight, and then return to earth without reaching orbit or deep space. A sub-orbital vehicle may be used for the purposes of commercial space flight, scientific research, point to point travel, cargo transportation, or Earth observation. Commercial space flight has become a reality with a number of companies promising the chance to experience space flight. These vehicles are currently in their test and development phase. In order to ensure the seamless development and transition to operational use of such vehicles, all of the regulatory issues, including the Radio Regulation provisions, need to be addressed. This agenda item will determine if sub-orbital vehicles (space planes) can be accommodated within existing radiocommunication services and allocations, or if it is necessary that a future WRC define new radiocommunication services and decide on appropriate spectrum allocations to accommodate these vehicles. Figure 1 shows the approximate distances of the atmospheric layers: the troposphere, stratosphere, and mesosphere. For the purpose of this discussion, the boundary between the Earth s atmosphere 10 and space is assumed to be 100 kilometers above the Earth s surface. 10 The boundary between the Earth s atmosphere and space is sometimes hypothetically assumed to be 100 kilometers above the Earth s surface, often referred to as the Karman line.

103 Figure 2 shows a sub-orbital vehicle (space plane) in flight below and above the boundary between space and the Earth s atmosphere. Resolution 763 (WRC-15) identifies a number of challenges that have to be addressed regarding the spectrum requirements of stations on board sub-orbital vehicles. The ITU Radiocommunication Sector is presently engaged in studying the current and future radio equipage on board sub-orbital vehicles. Studies will be required to identify any required technical and operational measures that could assist in avoiding harmful interference between radiocommunication systems and determine spectrum requirements to consider a possible future agenda item for WRC-23. These studies have been directed to be completed during the WRC-19 study cycle. [Some initial issues that have been identified regarding spectrum access for sub-orbital vehicles include: Is there a requirement for a new radiocommunication system definition for sub-orbital planes? Can space planes use existing aeronautical and/or satellite spectrum for their operations? If not, is there a need for a future agenda item to identify spectrum for this application? The determination of spectrum requirements should take into account considering f) of Resolution 763 (WRC-15). ] DISCUSSION [As a first step, it is necessary to address the question of what radiocommunication services are appropriate for stations on-board a sub-orbital vehicle (space plane). During Phase A of flight, the suborbital vehicle (space plane) is considered a terrestrial station and therefore could operate radiocommunication stations in terrestrial services. During Phase B of flight, the sub orbital vehicle (space plane) is operating beyond the boundary between the Earth s atmosphere and space. Article 1 of the Radio Regulations sets out the terms and definitions used within the Radio Regulations. Below are questions and answers according to the interpretation of ITU RR Article 1. Is a sub-orbital vehicle (space plane) a satellite? No, a sub-orbital vehicle (space plane) is not a body which revolves around another body of preponderant mass and which has a motion primarily and permanently by the force of attraction of that other body (RR No ). Is a sub-orbital vehicle (space plane) a spacecraft? Yes, it is a man-made vehicle which is intended to go beyond the major portion of the Earth s atmosphere (RR No ). Is a radiocommunication station operating on sub-orbital vehicle (space plane) a space station? Yes, it is a space station because it is located on an object which is beyond, is intended to go beyond, or has been beyond, the major portion of the Earth s atmosphere (RR No. 1.64). Is this radiocommunication considered space radiocommunication? Yes, it is considered space radiocommunication because it is any radiocommunication involving the use of one or more space stations or the use of one or more reflecting satellites or other objects in space (RR No. 1.8). CCPII _i

104 Is this radiocommunication considered radio astronomy? No, radio astronomy is based on the reception of radio waves of cosmic origin (RR No. 1.13). Figure 3 X At low altitudes (Phase A in Figure 2), sub-orbital vehicles (space planes) are similar to any other aircraft and therefore their radiocommunication stations would be considered an aircraft station or aircraft earth station within the scope of terrestrial stations. Aeronautical services within the mobile service and mobile satellite service would continue to be appropriate for this operation (shown in green in Figure 3). Once sub-orbital vehicles (space planes) reach altitudes beyond the majority of the Earth s atmosphere (more than 100 km) they would then be regarded as spacecraft and their radiocommunication stations would be considered a space station since they do not fit the definition of a satellite. As a result, the space station radiocommunication would be regarded as space communication (shown in red in Figure 3). Does the radiocommunication, beyond the majority of the Earth s atmosphere, fall within the definition of space operation service? Yes, it is a radiocommunication service concerned exclusively with the operation of spacecraft, in particular space tracking, space telemetry and space telecommand (RR No. 1.23). Does the radiocommunication, beyond the majority of the Earth s atmosphere, fall within the definition of space research service? No, the radiocommunication is not used for scientific or technological research purposes (RR No. 1.55). Given the existing definitions in Article 1 of the Radio Regulations, there seems to be no need for new definitions either for services or stations for sub-orbital vehicles. These vehicles can be accommodated within existing definitions.] CCPII _i

105 PRELIMINARY VIEW Canada, USA To support studies called for by Resolution 763 (WRC-15), noting that those studies need to be completed during this study cycle. Based on the outcome of those studies, consider a possible future agenda item for WRC-23. Canada Canada is of the view that existing station and service definitions in Article 1 of the Radio Regulations can be applied to sub-orbital vehicles (space planes). CCPII _i

107 Agenda item 9.1, issue 9.1.5: Resolution 764 (WRC-15) - Consideration of the technical and regulatory impacts of referencing Recommendations ITU R M and ITU R M in Nos F and 5.450A of the Radio Regulations. BACKGROUND Under agenda item 9.1, the Director of the Radiocommunication Bureau reports on the activities of the Radiocommunication Sector since the last conference. This includes specific activities or issues for which the Director is explicitly instructed, via certain Resolutions, to provide a report either to the next or future conference(s) for consideration. Issue relates to consideration of the technical and regulatory impacts of updating the references to the latest version of Recommendation ITU-R M Characteristics of and protection criteria for sharing studies for radiolocation, aeronautical radionavigation and meteorological radars operating in the frequency bands between and MHz and adding a reference to Recommendation ITU-R M Technical and operational aspects of ground-based meteorological radars in footnotes 5.447F and 5.450A of the Radio Regulations. Footnote 5.447F states: In the frequency band MHz, stations in the mobile service shall not claim protection from the radiolocation service, the Earth exploration-satellite service (active) and the space research service (active). These services shall not impose on the mobile service more stringent protection criteria, based on system characteristics and interference criteria, than those stated in Recommendations ITU-R M and ITU-R RS (WRC-15). A similar footnote 5.450A states In the frequency band MHz, stations in the mobile service shall not claim protection from radiodetermination services. Radiodetermination services shall not impose on the mobile service more stringent protection criteria, based on system characteristics and interference criteria, than those stated in Recommendation ITU-R M (WRC-15). Recommendation ITU-R M has now been updated to M ITU-R WP 5A is to investigate the impact of referencing the new version of the recommendation to these services referred to in the footnotes. Furthermore, it has been suggested that there should be a new reference to Recommendation ITU-R M in the footnotes. The impact of which is also to be investigated. In Canada, there is a RADARSAT Constellation Mission (RCM) that has six satellites in the constellation. The first three satellites which will be launched in 2018 will use the frequency band MHz and the remaining three satellites are expected to operate in the frequency range MHz (under the international primary allocation to the Earth exploration satellite service (EESS) (active)). The data provided (or to be provided) by these constellations is vital for reliable and up-to-date information on how our planet and its climate are changing and assist in planning to prevent global warming effects. There is also a Canadian national radar network that operates in the frequency band MHz (under the international primary allocation to the radiolocation service). These radars are in operation continuously 24 h/day and play a crucial role in the immediate meteorological and hydrological alert processes. The data from these radars is also used in scientific research to better understand the physics and model the behaviours of significant weather events, and in providing climate information regarding the occurrence of significant weather events in Canada. CCPII _i

108 Due to the growing need to off-load broadband traffic onto Wi-Fi networks, specifically in the 5 GHz band, the current and future proliferation of Wi-Fi networks and devices is also an important consideration. According to Cisco 11, public and home Wi Fi hotspots in Canada alone will grow from 0.8 million to 10.2 million between 2015 and 2020; representing a 13 fold increase. Internationally, there is also a primary mobile allocation in the frequency bands MHz and MHz for the implementation of wireless access systems (WAS), including radio local area networks (RLANs). Recommendation ITU-R M (referenced as well in the updated Recommendation ITU-R M ) recommends that the aggregate protection criteria for ground-based meteorological radars should be an I/N of 10 db. The underlying question being investigated by WP 5A then becomes whether an international change to the regulatory environment would still allow RLANs to operate. ISSUES Investigation of the technical and regulatory impacts on the services referred to in footnotes 5.447F and 5.450A of the Radio Regulations that would result from updating or including a new reference to the updated versions of Recommendation ITU-R M and M Ensure that no undue constraints are imposed on the services referenced in these footnotes, including, inter alia RLANs operating in the mobile service. DISCUSSION The latest working document towards draft CPM text for WRC-19 agenda item 9.1, issue 9.1.5, is contained in Annex 12 to Doc. 5A/469, the WP 5A Chairman s Report of the May 2017 meeting. It includes the text from the input contributions received so far. The working document towards draft CPM text will be progressed at the upcoming WP 5A meetings on 6-16 November 2017 and May 2018, at which time the draft CPM text will be completed. PRELIMINARY VIEWS CAN Canada supports and is participating in the studies on the technical and regulatory impacts as described in Resolution 764, which are being conducted in WP 5A. Canada is of the preliminary view that there is a need to avoid introduction of ITU-R M in the RR as there appears to be, based on current studies, significant impacts on RLAN DFS requirements if Recommendation ITU-R M were to be referred to in place of Recommendation ITU R M This is because some of the new radars (i.e., bistatic and frequency hopping radars) have substantially different system characteristics. Canada continues to follow the studies in WP 5A including those on the referencing of Recommendation ITU-R M Global Wi-Fi Market Global Forecast to 2020 Market, TC 2650, 2015 CCPII _i

110 Agenda Item 9.1.6: Urgent studies required in preparation for WRC-19 - Studies concerning Wireless Power Transmission (WPT) for electric vehicles. BACKGROUND The World Radiocommunication Conference 2015 (WRC-15) decided on the agenda for the upcoming World Radiocommunication Conference scheduled for 2019 (WRC-19). Among other items, WRC-19 agenda item 9.1, issue 6 addresses urgent studies concerning Wireless Power Transmission (WPT) for electric vehicles (EV). The related Resolution 958 (WRC-15) to the WRC-19 deals with studies to assess the impact of WPT-EV on radiocommunications services and study suitable harmonized frequency range for this system. These activities are conducted under WP 1B, responsible for ITU Documents 1B/237 Section and 3; Annexes 1 to 5. ISSUES All candidate bands are on VLF/LF portion of the radio spectrum (19-25 khz, khz, khz, khz), favorable to more effectively inductive coupling (near-field induction mechanisms) between the charging pad and the electric vehicle. Previous studies considered emission limits applied to short range devices (SRD) in ITU-R SM However recent studies performed by IARU for WP1 B (Contribution 89) states these limits are not applicable since the recommendation is devoted to devices using low power, short duration and intermittent operations, instead WPT-EV systems are configured for heavy duty cycle operation with uncertainty variability in the fundamental frequency (with possible poor sideband and phase noise performance), using very high power to drive the charging. According WP1 B Chairman s Report, Annex 1: In most use cases for passenger vehicles at their home garage, 3.3 kw or equivalent charging power could be accepted. However, some users may want to charge their cars quickly or they use their cars for specific purposes, which may need much higher power levels, e.g. 20 kw or higher. For heavy duty vehicles, this may be much higher. As an initial level, 75 kw equivalent charging power may be required. The 100 kw or higher power ranges are also taken into consideration for charging the batteries of heavy duty vehicles. These characteristics raised concerns in the generation of harmonics in several orders, able to spread across large portions of the spectrum, therefore affecting several radio services not only in VLF and LF, but also in MF and HF. The IARU document concluded, If these limits were adopted, the harmful interference will be inevitable in Amateur, Broadcasting, Maritime, scientific networks to the detection of lighting and other services from 200 khz to khz. Taking account the expectation of high density of use of WPT-EV systems in urban/suburban environments, the cumulative source of high power noise should be considered close to the domestic users of radio services. Comparisons developed in ITU-R WP1A Contribution 141 show the gap between the current ITU SM limits and the ITU-R P372 background noise level. Spurious emissions at the SM level exceed the noise level by 40 to 50 db at 10 m distance. Comparisons did in ITU-R WP1B CCPII _i

111 Contribution 283 included the CEPT and CISPR-11 limits, expressing similar degradation of the spectrum (Figure 1). Figure 1: Comparison of spurious limits at 10 m with standard man-made noise levels. A study deployed in the same contribution considered 528,280 data points of A1A 500 Hz bandwidth S/N ratios of Amateur Service happened in 2018, demonstrating how the raising of the background noise could severe impact in the service. PRELIMINARY VIEWS Brazil The Brazilian Administration supports the studies concerning Wireless Power Transmission (WPT) for electric vehicles as long as it does not impact in the operation of the incumbent radio services, providing appropriate limits are adopted for the protection of the radio services, including spurious and their harmonics.
