3 Introduction The tenth meeting of Task Group 8/1 was held in Mainz, Germany from 15 to 26 April The meeting was attended by 126 delegates from 22 Administrations and 3 international organisations, including several experts who are active members of ITU-T Study Groups (see Attachment 26): Australia Brazil Canada Côte d Ivoire Finland France Germany Hungary India Israel Italy Japan Korea Malaysia New Zealand Norway Poland Russia Spain Sweden UK USA Inmarsat INTELSAT ETSI The meeting was chaired by Mr. M.H. Callendar (Canada), Chairman of this Task Group. A total of 82 input documents as shown in Attachment 27 were considered. The meeting was conducted by way of opening, intermediate and final plenary sessions interspersed by detailed work conducted by the following appointed Program Management Team (PMT), Working Groups and Ad Hoc Groups: Group Chairperson Subject PMT * - Program Management Team WG 1 Ashok Kumar IMT-2000/FPLMTS for developing countries WG 2 Horst Mennenga Terminology for IMT-2000/FPLMTS WG 3 Gene Rappoport FPLMTS services WG 5 Alan Maclatchy Satellite component of IMT-2000/FPLMTS WG 6 David McFarlane Common radio-related functions WG 7 Garth Jenkinson Radio interfaces WG 8 Rick Engelman Migration towards IMT-2000/FPLMTS AH 1 Edgar Lycksell Electronic Working Methods AH 2 Sabah Towaij Radio interface development process AH SG 2 Davide Grillo Liaison with ITU-T SG 2 AH SG 11 Edgar Lycksell Liaison with ITU-T SG 11 The input documents were assigned to the groups as shown in Attachment 27. Forty-eight temporary documents (Docs. 8-1/TEMP/1 through 48) were produced during the meeting (Attachment 28). 2. Objectives Set The major specific objective set for this meeting was the approval of the draft new Recommendation FPLMTS.REVAL (Evaluation of Radio Transmission Technologies). Other important activities for * The members of PMT at this meeting were: Rick Engelman, Roger Fudge, Edgar Lycksell, Akio Sasaki, Robert Tompkins and Sabah Towaij (FPLMTS Program Manager).

4 - 4 - the tenth meeting included approval of any necessary updating of existing FPLMTS Recommendations and further development of radio-related common functions in Working Group Summary of Results The meeting approved draft new Recommendation REVAL (Guidelines for Evaluation of Radio Transmission Technologies for FPLMTS) * and draft revisions updating four existing Recommendations (687, 816, 819 and 1034). These documents will be submitted, in addition to draft new Recommendations TMLG and ESM which were approved at the ninth meeting of TG 8/1 in Tokyo, to the meeting of Study Group 8 on October 28th, 1996 for approval by correspondence under Resolution ITU-R 1-1. Considerable effort was spent in defining the overall process for production of recommendations for the radio interface(s) for IMT-2000/FPLMTS, i.e. proposal of radio transmission technologies to TG 8/1, evaluation and selection of technologies followed by detailed radio interface definition (RSPC Series of Recommendations). A major outcome of this work was the decision to utilize the considerable resources of individual M(m)embers of the ITU to carry out detailed evaluations of the various proposed radio transmission technologies for IMT-2000/FPLMTS. The results of these various multiple independent evaluations of the various proposed radio transmission technologies would be submitted to TG 8/1 with the objective of consensus building, possible grouping, synthesis of common features, etc. In this way "market forces" would effectively determine the level of effort applied to evaluating the various proposed technologies and "peer review" would assist TG 8/1 in the validation of the various contributions. The meeting approved the overall development process for radio interface Recommendations (Attachment 6) but was unable to agree on the detailed time scales for the various stages of the process, much of which is controlled by forces outside the ITU s control. A "best case estimate" is given in Attachment 7, further work on these matters will be carried out at the next meeting. A proposed draft new Recommendation on Framework for Modularity within FPLMTS (MOD) (Attachment 18), based on maximizing common radio related functionality across the various radio operating environments, is being prepared by Working Group 6 for approval at the 12th meeting of TG 8/1 in February This work will be the major focus of the 11th and 12th meetings of TG 8/1 as this Recommendation will assist "network evolution from second generation mobile systems and should also simplify the eventual selection of radio transmission technologies for IMT-2000/FPLMTS. For the purpose of assisting progress of the meeting, a Chairman's Steering Group was formed as in previous meetings. In order to assure close liaison with ITU-T, ITU-R and ITU-D Study Groups, nomination of liaison rapporteurs were confirmed as follows: FPLMTS Program Manager (prime link to ICG-FPLMTS) ITU-T SG 1 Sabah Towaij Gene Rappoport * Some European Administrations expressed their reservations with respect to the approval by TG 8/1 of REVAL (see Attachment 25). It is hoped that these concerns can be resolved prior to or at the 11th meeting of TG 8/1, i.e. before the meeting of Study Group 8 on October 28th, 1996.

5 ITU-T SG 2 ITU-T SG 4 ITU-T SG 11 ITU-T SG 12 ITU-T SG 13 ITU-T SG 15 ITU-R WP 8A ITU-R WP 8D ITU-R SG 9 ITU-D SG Davide Grillo Akio Sasaki Ed Chien Gene Rappoport Jose Costa Dae Gwon Jeong Robert Tompkins Allan Maclatchy Gene Rappoport Sabah Towaij Special Rapporteurs on regional activities nominated at the sixth meeting will continue to serve as follows: Region 1: Robert Tompkins (UK) Region 2: Gary Jones (USA) Jose Costa (Canada/CITEL) Region 3: Akio Sasaki (Japan) Considering the progress made at this meeting the ongoing organizational structure for TG 8/1 was agreed to be as summarized in Attachment Developing Countries (WG 1) The detailed report from the Chairman of WG 1 (Ashok Kumar, India) is given in Attachment 8. Working Group 1 reviewed the modifications to Recommendation ITU-R M.819 approved in Tokyo and in the absence of any further inputs forwarded these revisions, with minor editorial changes, to the TG 8/1 plenary for approval and submission to Study Group 8 on October 28th, A liaison statement was sent to WG 7 outlining changes to REVAL needed to reflect the importance of Fixed Wireless Access (FWA) applications of FPLMTS to the needs of developing countries. 3.2 Terminology (WG 2) This group did not meet as the only input contribution on this topic (Doc. 8-1/43) was withdrawn. 3.3 Services (WG 3) The detailed report from the Chairman of WG 3 (Gene Rappoport, USA) is given in Attachment 9. Modifications to Recommendation ITU-R M.816 based on input contributions were prepared, and liaison statements sent to ITU-T SGs 2 and 11. The Chairman of WG 3 recommended that WG 3 be discontinued as no significant additional work is foreseen since ITU-T SG 1 is now responsible for IMT-2000/FPLMTS service aspects. 3.4 Satellite (WG 5) The detailed report from the Chairman of WG 5 (Allan Maclatchy, Canada) is given in Attachment 10. The main focus of the work was to ensure that satellite issues were appropriately addressed in REVAL.

6 - 6 - There was considerable discussion as to what extent global satellite systems, which inherently provide global roaming - one of the major requirements of IMT-2000/FPLMTS, need to be considered in the REVAL process. (See Annex 1 to Attachment 10). Clearly the network, service and quality aspects of these systems would need to be appropriate for IMT-2000/FPLMTS, but the question is to what extent does the physical layer (satellite radio transmission technology) have to be evaluated in conjunction with other terrestrial/satellite SRTTs. This discussion will be carried over to the next TG 8/1 meeting but clearly the aim of maximizing commonality of the physical layer across all IMT-2000/FPLMTS radio operating environments, and hence simplifying mobile terminals for both terrestrial and satellite operation, will not be achieved if satellite radio transmission technologies are not included in the evaluation and selection processes. Liaison statements were sent to WP 8D and WP 3M. 3.5 Radio Related Functions (WG 6) The detailed report from the Chairman of WG 6 (David McFarlane, UK) is given in Attachment 11. A proposed draft new Recommendation FPLMTS.MOD: Framework for Modularity within FPLMTS is being developed within WG 6 based on a number of input contributions (see Attachment 18). This work will be a major focus of the 11th and 12th meetings of TG 8/1 with the aim of approving this Recommendation at the 12th meeting for presentation to the Study Group 8 meeting in June A correspondence group has been established to carry on the WG 6 work between meetings and contributions are urgently needed to complete this new Recommendation in the proposed time frame. Dr. Dae Gwon Jeong, Korea, was appointed liaison rapporteur to ITU-T Study Group 15 to replace Richard French who has retired. It is hoped that some SG 15 experts will attend the 11th meeting of TG 8/1 to discuss the various multimedia compression and control technologies currently being standardized by SG 15. A liaison rapporteur is urgently needed for the new wireless ATM activities currently being addressed in the ATM Forum to ensure that there is no duplication of effort with the work in the ITU. 3.6 Radio Interface(s) (WG 7) The detailed report from the Chairman of WG 7 (Garth Jenkinson, Australia) is given in Attachment 12. As a result of the REVAL Validation Group meeting, hosted by the US in Clearwater, Florida in February 1996, and the tremendous effort in Mainz, it was possible to approve REVAL at the final plenary session. Due to the new approach for carrying out evaluations on SRTTs, REVAL is now titled "Guidelines for Evaluation of Radio Transmission Technologies for IMT-2000/FPLMTS". The new approach to the evaluation of radio transmission technologies for IMT-2000/FPLMTS enables TG 8/1 to leverage the substantial technical resources of ITU M(m)embers to assist in this highly complex process. Attachment 6 defines the overall development process of radio interface specifications which includes: submission of candidate SRTTs, evaluation, selection and production of Recommendations (RSPC Series). Please note that Step 6 carries the following note: "The performance parameters for FPLMTS will be considered further during the meeting of TG 8/1 in October. A table of performance requirements will then be produced to be used for screening

7 - 7 - purposes after the receipt of the evaluation reports". In order to address this issue contributions to the October 1996 TG 8/1 meeting are urgently requested. Other areas for which contributions to the October meeting are requested are further development of the structure for the RSPC Series of Recommendations and possible updates to Recommendation ITU-R M.1036 as a result of WRC-95 and other recent developments. (See WG 7 Chairman s Report). 3.7 Migration to IMT-2000/FPLMTS (WG 8) The detailed report from the Chairman of WG 8 (Rick Engelman, USA) is given in Attachment 13. Further work towards completion of the Draft Report on Evolution and Migration to IMT-2000/FPLMTS was carried out and a correspondence group was established to continue this work between the Mainz and Geneva meetings of TG 8/1. Rick Engelman and Paul Marrangoni, USA (the WP 8A Rapporteur for migration issues) will co-chair this activity to ensure close liaison with the complementary work in WP 8A. 3.8 Program Management Team (PMT) The detailed report from the PMT is given in Attachment Electronic Working Methods (AH 1) The detailed report from the Chairman of AH 1 (Edgar Lycksell, Sweden) is given in Attachment 14. The delegates at the meeting expressed their appreciation for the great effort by the ITU-BR secretariat in getting practically all the input documents for the Mainz meeting posted on TIES so that they could be downloaded and read prior to the start of the meeting. This very valuable service has, however, involved a great deal of effort in conversion, cleaning up and alignment of the documents, so a number of proposed measures to reduce this effort were discussed and are given in Attachment 14. The use of the special TG 8/1 distribution lists and other ITU services such as on line availability of Recommendations were also discussed. Would all those involved review their e- mail address and any lists that they are involved with to bring them up to date and remove any unnecessary entries. Electronic working will be the key to managing the large amount of information expected by TG 8/1 during the REVAL process. Special servers and the use of compressed files will undoubtedly be needed to facilitate easy access to all the evaluation material likely to be available. It would be a good idea to form a small task group to begin to think about this now rather than being swamped later on! Fabio Leite requested that problems with TIES be sent directly to helpdesk@itu.ch instead of to him personally as he would have to forward them which could cause delay Radio Interface Development Process (AH 2) The detailed report from the Chairman of AH 2 (Sabah Towaij, Canada) is given in Attachment 15.

8 - 8 - A great deal of effort was devoted to the definition of the overall IMT-2000/FPLMTS radio interface development process, i.e. submission to TG 8/1 of candidate radio transmission technologies, evaluation, selection and preparation of appropriate recommendations (RSPC Series). A number of high level issues, raised in input contribution Doc. 8-1/18, were discussed to establish the views of TG 8/1 members as a basis for the definition of the overall development process. A summary of the majority views are given below (see Attachment 4 for more details): 1) There should be a formal ITU selection process for radio transmission technologies for IMT-2000/FPLMTS but it was not clear whether this selection process would result in, or should be intended to identify, a single set of RTTs. 2) The output of this selection process should result in a recommendation RKEY. 3) Further work towards the production of specifications for the radio subsystems should be undertaken within the ITU. 4) The level of ITU standardization required and the time scales involved were not resolved at this stage of the discussions. A major outcome of further discussions on the overall development process was the decision to utilize the considerable resources of individual M(m)embers of the ITU to carry out detailed evaluations, based on REVAL, of the various proposed radio transmission technologies for IMT-2000/FPLMTS. The results of these various multiple independent evaluations of the various proposed radio transmission technologies would be submitted to TG 8/1 with the objective of consensus building, possible grouping, synthesis of common features, etc. While this new approach should ensure that sufficient technical resources will be available to carry out the highly complex evaluation process, and also provides some flexibility for individual groups to refine the process somewhat, it will not necessarily make the task of reaching consensus on the requirements for the IMT-2000/FPLMTS radio interfaces any easier. The TG 8/1 plenary approved the overall development process for IMT-2000/FPLMTS radio interface Recommendations (see Attachment 6) but was unable to agree on the detailed time scales for the various stages of the process, much of which is controlled by forces outside the ITU s control. A "best case estimate" is given in Attachment 7; further work on these matters will be carried out at the next TG 8/1 meeting in October In preparation for the formal ITU request for submission of RTTs, after REVAL has received full ITU approval, a draft circular letter was prepared (see Annex 1 to Attachment 6). A summary, for inclusion with the circular letter, of IMT-2000/FPLMTS requirements and objectives based on existing approved ITU Recommendations was complied, together with an associated template to aid those submitting RTTs to provide all the relevant information, and approved by the TG 8/1 plenary (see Attachment 5 and Annex 2 to Attachment 6) Liaison to ITU-T Study Group 2 (AH SG 2) A liaison was prepared by the Chairman of AH SG 2 (Davide Grillo, Italy) to ITU-T Study Group 2 responding to their liaisons to TG 8/1.

9 Liaison to ITU-T Study Group 11 (AG SG 11) The detailed report from the Chairman of AH SG 11 (Edgar Lycksell, Sweden) is given in Attachment 16. A liaison was prepared to ITU-T Study Group 11 responding to their liaisons to TG 8/1. The possibility of further joint meetings with SG 11 experts, based on the success of the recent joint meetings in Tokyo, was discussed with November 1996/February 1997 as potential dates for the next joint meeting. ITU-T SG 11 Question 29 is now working on IMT-2000/FPLMTS security matters but as yet there is no confirmation on which ITU-T Study Group has prime responsibility for this important topic. This matter was stressed in the letter from the Chairman of TG 8/1 to the BR Director after the last TG 8/1 meeting in Tokyo and has been discussed with the Director of the Telecommunication Standardization Bureau. Urgent clarification is needed of who is responsible for this critical topic. 4. Future Work 4.1 Work before the start of the eleventh meeting Correspondence activities between the tenth and eleventh meetings of TG 8/1 have been established as shown below: Correspondence groups and future work WG Subject Dates Contact Point ( address) 5 Application of REVAL to satellite radio interface (see Annex 1 to Attachment 10) 6 Rec. FPLMTS.MOD (see Attachment 18) FPLMTS.RRF (see Attachment 20) FPLMTS.RC (see Attachment 21) 7 Performance parameters for FPLMTS Rec (FPLMTS spectrum) (see Attachment 12) FPLMTS.RSPC (see Attachment 19) 8 Report on Evolution and Migration (see Attachment 22) Before October 1996 Chairman WG 5 (tg8-1sat@itu.ch) Chairman WG 6 (tg8-1rfc@itu.ch) Editor RRF: (medici@issy.cnet.fr) Editor RC: (patrick.plas@issy.cnet.fr) Chairman WG 7 (tg8-1rad@itu.ch) Chairman SWG 7-2 (Francois.DERYCK@issy.cnet. fr) Chairman WG 8 (tg8-1mig@itu.ch)

10 Eleventh meeting in Geneva, Switzerland A major focus of the 11th meeting of TG 8/1, October 15-25th 1996, will be work towards completion of the proposed draft new Recommendation FPLMTS.MOD on Framework for Modularity within FPLMTS which is being prepared by Working Group 6 for approval at the 12th meeting of TG 8/1 in February 1997 and presentation to the Study Group 8 meeting (June 9-12th 1997). This Recommendation is important because its timely availability will greatly assist "network" evolution from second generation mobile systems and should also simplify the eventual selection of radio transmission technologies for IMT-2000/FPLMTS. Contributions to the WG 6 correspondence group and the 11th meeting are urgently required to ensure completion of the recommendation in this short time frame. It is hoped that some SG 15 experts will attend the 11th meeting of TG 8/1 to discuss the various multimedia compression and control technologies currently being standardized by SG 15. Contributions are urgently needed to develop a table of performance requirements for IMT- 2000/FPLMTS to be used for screening purposes after the receipt by TG 8/1 of evaluation reports on the various proposed radio transmission technologies (Step 6 of REVAL). Further input on the proposed time schedule for the overall radio interface development process (Attachment 7) is also required. Other areas for which contributions to the 11th meeting are requested are further development of the structure for the RSPC Series of Recommendations and possible updates to Recommendation 1036 as a result of WRC-95 and other recent developments. (See WG 7 Chairman s Report). 4.3 Activities beyond the eleventh meeting By the kind invitation of the Korean Administration, the twelfth meeting of TG 8/1 is currently planned to be held in Korea from February 18-28th 1997 and it is hoped that final details will be confirmed at the 11th meeting in Geneva. The Canadian Administration and members of the Canadian telecommunications industry indicated that they are considering hosting the thirteenth meeting of TG 8/1, possibly from September 8-19th A joint meeting with experts of ITU-T Study Group 11 is being planned, possibly as early as November 1996 or in conjunction with our 12th meeting in February It is never too early to start thinking about potential host countries for future TG 8/1 meetings, i.e. possibly in April and October The success of the work of TG 8/1 is, I believe, largely due to the generosity of the many Administrations around the world who have hosted our meetings, and in so doing provided some understanding of the culture and way of life in their regions. Without this "team building" hospitality it would have been very difficult to reach consensus on the many challenging issues we have resolved in the production of the fifteen recommendations so far approved by TG 8/1.

19 ANNEX 2 TO ATTACHMENT 1 Scope statements for all ITU-R FPLMTS Recommendations Recommendation ITU-R M Future Public Land Mobile Telecommunication Systems (FPLMTS) Starting from Questions ITU-R 39/8 and 77/1, Recommendation ITU-R M defines the objectives to be met by FPLMTS and provides the overall FPLMTS concepts with particular consideration to achieving worldwide roaming and compatibility. This Recommendation provides a high level statement on the topics of: services, architecture, network aspects, implementation, sharing, and operational characteristics. Guidance is provided, for a limited number of possible scenarios, on spectrum bandwidth and band of operation based on critical technical parameters and traffic estimates. It forms a foundation for the subject of FPLMTS and for the subsequent work activities and recommendations. Recommendation ITU-R M. [FPLMTS.TMLG] - Vocabulary of Terms for FPLMTS This Recommendation consists primarily of those terms and definitions that are considered essential to the understanding and application of the principles of FPLMTS. Included are terms that may already be defined in other ITU Recommendations. However, the definitions given here embrace only the essential concepts and on this basis it is considered that they are not inconsistent with the more specialized definitions that appear in those Recommendations. The terms defined below are not exclusive to FPLMTS, and so far as they are relevant, may also apply to other radiocommunication systems and services. Where a truncated term is widely used in an understood context, the complete term is quoted following the colloquial form. Recommendation ITU-R M Security Principles for FPLMTS The scope of this Recommendation is to provide the principles and framework for the security provided by FPLMTS. The Recommendation covers all aspects of security for FPLMTS and is intended as a basis for more detailed aspects of FPLMTS security to be integrated in various ITU-R or ITU-T Recommendations including FPLMTS requirements at a later stage. The Recommendation identifies the security requirements for FPLMTS and defines security features for FPLMTS. An informative Annex to the Recommendation contains a threat and risk analysis including the justification for the various security features defined. The system requirements on security in this Recommendation does not imply any legal responsibility of involved parties concerning the security of the communication and associated information as this will be in accordance with a country s national law. The management of security features is dealt with in Recommendation ITU-R M.1168.

20 Recommendation ITU-R M FPLMTS Network Architectures This Recommendation presents the functional network architectures and some of the resulting network configurations which are possible for FPLMTS. It should form the basis for defining the information flows within FPLMTS. Recommendation ITU-R M Satellite Operation within FPLMTS The Recommendation provides high level guidance on the integration of the satellite component into FPLMTS. In particular, it comments on the critical technical factors for selection of band of operation and identifies subsequent work to be carried out. Recommendation ITU-R M FPLMTS for Developing Countries Recognizing the disparity that exists in the telecommunication infrastructures in the world, this Recommendation points out the potential of cellular technology (and its evolution into FPLMTS technologies) to help developing countries bridge the gap. FPLMTS have been conceived primarily for mobile telecommunications which of course is of interest to developing as well as developed countries. The objective of this Recommendation is to emphasize the needs and interest of developing countries by promoting the application of FPLMTS for fixed services. It should furthermore be stressed that the use of FPLMTS for such applications is also attractive to developed countries. Recommendation ITU-R M Requirements for the Radio Interface(s) for FPLMTS The purpose of this Recommendation is to build on the FPLMTS concepts contained in Recommendation ITU-R M.687 and to provide a high-level view of the constraints placed on the radio interface(s) particularly in terms of the system requirements, user requirements, and operational requirements. It takes account of other FPLMTS Recommendations to produce recommendations on the requirements for the FPLMTS radio subsystem from an overall system perspective. Recommendation ITU-R M.[FPLMTS.ESM] - Evaluation of Security Mechanisms for FPLMTS The scope of this Recommendation is to identify classes of security mechanisms appropriate for implementing the FPLMTS security features defined in Recommendation ITU-R M.1078 on security principles for FPLMTS, and thus for satisfying the FPLMTS security requirements identified in the same Recommendation. This Recommendation is intended to be a starting point for the development of more detailed FPLMTS recommendations relevant to security which will be developed by various ITU Study Groups. Recommendation ITU-R M Spectrum Considerations for Implementation of FPLMTS in the Bands MHz and MHz At this stage of FPLMTS development it is neither appropriate or possible to produce a definitive Recommendation on FPLMTS operation in the bands MHz and MHz. However a more general Recommendation on the relevant principles covering the exploitation of these bands by FPLMTS can provide valuable early advice to Administrations to enable them to plan use of the relevant bands.

21 Thus the purpose of this Recommendation is to give principles to guide Administrations on spectrum technical issues relevant to the implementation of FPLMTS in the bands identified by WARC-92, while minimizing the impact on other systems and services in the bands and facilitating FPLMTS growth as countries require it. Recommendation ITU-R M Speech and Voiceband Data Performance Requirements for FPLMTS This Recommendation defines the speech quality and voiceband data performance requirements for the Future Public Land Mobile Telecommunication Systems (FPLMTS), including the satellite aspects. It lists the basic recommendations essential for achieving speech and voiceband data quality comparable to the fixed network by specifying natural speech, free, for example from excessive delay and echoes, that will enable users to converse easily using the FPLMTS network, taking account of the full range of impairments like transcoding and environmental noise that are to be expected. Acceptable bit error ratios are also defined. This Recommendations also defines the connection performance, concerning issues like call set up time and handover probability, to be achieved in the FPLMTS network that the user will expect in a network of comparable performance to the fixed network. Recommendation ITU-R M Framework for Services Supported on FPLMTS This Recommendation forms a framework for continued development towards detailed FPLMTS service descriptions as defined in the proposed ITU-T draft Recommendation F.115. A phased approach is adopted for the definition of FPLMTS. In this Recommendation the services required for Phase 1 are described, and an outline of the services for Phase 2 is also given. Phase 1 includes those services supported by user bit rates up to approximately 2 Mbit/s. Phase 2 is envisaged as augmenting Phase 1 with new services, some of which may require higher bit rates. Recommendation ITU-R M Framework for the Radio Interface(s) and Radio Subsystem Functionality for FPLMTS The purpose of this Recommendation is to present an overview of the radio subsystem for FPLMTS and give guidelines for the development of the structure of the radio subsystem. The radio subsystem includes the functionalities needed to provide FPLMTS services over (a) radio interface(s) to mobile terminals in all FPLMTS operating environments, as defined in Recommendation ITU-R M The Recommendation provides a high-level definition of logical elements and functionalities within the radio subsystem, including the radio interface, channel structure, link control and radio system management functions. In addition, this Recommendation identifies areas which are to be specified in detail in subsequent Recommendations. Recommendation ITU-R M Framework for the Satellite Component of FPLMTS Recommendation ITU-R M.818 sets the overall requirements of the satellite component of FPLMTS. Recommendation ITU-R M.1035 describes the framework of the radio interfaces of FPLMTS taking particular account of the terrestrial component. This Recommendation together with Recommendation ITU-R M.1035 describes the technical and operational capabilities and features of the satellite component, particularly where they are distinct

22 from those of the terrestrial component. It forms the framework for further development of the satellite component of the integrated overall systems of FPLMTS. In particular, the Recommendation comments on the aspects of integration with the terrestrial component, operational considerations, network interfaces and radio interfaces. Recommendation ITU-R M Framework of FPLMTS Management The purpose of this Recommendation is to present the conceptual and methodological framework of the definition of the management of FPLMTS. The methodology described in ITU-T Recommendation M.3020 is used to define management requirements, management services, management functions, information models, and management protocols related to the management of FPLMTS. This framework is the initial Recommendation on FPLMTS management and identifies objectives for FPLMTS management and provide guidelines for the specification of Recommendations on FPLMTS management, particularly a TMN Management Service on FPLMTS. Other Recommendations on FPLMTS management will be produced by ITU in the near future. FPLMTS.MOD - Framework for Modularity within FPLMTS The scope of this Recommendation is to identify and describe the modularity aspects of the radiorelated functions of FPLMTS. Specifications of the radio related functions and procedures form part of the FPLMTS.RSPC series of Recommendations. To minimize costs and ease service and network deployment, it is necessary to minimize the number of radio interfaces and maximize the commonality between them. From these general goals arises the approach taken in FPLMTS.RC to assess the commonality between the radio functions identified in FPLMTS.RRF. Other requirements include recognition of the convergence between fixed and mobile networks in conjunction with an easy migration of existing mobile networks. It is thus necessary to have a clearer view of the requirements lying on the transport mechanisms at the radio interface. This Recommendation provides a Framework of the commonality, complementing the more detailed information in the baseline document FPLMTS.RC. FPLMTS.RRF - Baseline Document on Radio Related Functions for FPLMTS The scope of this Baseline Document is to identify and describe all radio-related functions of FPLMTS. The list of functions identified in this Baseline Document and the associated descriptions are used as basis for the evaluation process defined in the Recommendation FPLMTS.REVAL to assess commonality. Specifications of the radio related functions and procedures form part of the FPLMTS.RSPC series of Recommendations.

23 FPLMTS.RC - Baseline Document on Radio Related Commonality This document identifies the FPLMTS radio-related functions and parameters that can be made common across multiple radio operating environments. The technical requirements and the rationale for commonality to apply are also stated. This document supports the development of the radio transmission technology selection process (in particular with respect to the definition of commonality criteria in FPLMTS.REVAL), the choice of the key radio technologies (FPLMTS.RKEY) and the specification of the radio subsystem (FPLMTS.RSPC). It also supports the development of network signalling specifications relevant to FPLMTS in ITU-T. Recommendation ITU-R M.[FPLMTS.REVAL] - Guidelines for Evaluation of Radio Transmission Technologies for FPLMTS This Recommendation provides guidelines for both the procedure and the criteria to be used in evaluating RTTs for a number of test environments. These test environments, defined herein, are chosen to simulate closely the more stringent radio operating environments. The evaluation procedure is designed in such a way that the impact of the candidate RTTs on the overall performance and economics of IMT-2000/FPLMTS may be fairly and equally assessed on a technical basis. It ensures that the overall IMT-2000/FPLMTS objectives are met. The Recommendation provides, for proponents and developers of RTTs, the common bases for the submission and assessment of RTTs and system aspects impacting the radio performance. This Recommendation allows a degree of freedom so as to encompass new technologies. The actual selection of the RTTs for IMT-2000/FPLMTS is outside the scope of this Recommendation. It deals only with the methodology for the technical evaluations that should be performed. The results of the evaluation are to be documented in an evaluation report and submitted to the ITU-R. [Recommendation FPLMTS.RKEY - Key Choices of Technologies for the Radio Interfaces of FPLMTS The purpose of this Recommendation is to define key radio technology aspects, for subsequent detailed specification in the FPLMTS.RSPC series of Recommendations, based on the application of the evaluation procedures given in FPLMTS.REVAL and further contributions. (FPLMTS.RKEY may be in the form of a Recommendation, a Report or a Task Group 8/1 internal note.)] Recommendation FPLMTS.RSPC.1 - Radio Interface Specification Outline for FPLMTS The purpose of the FPLMTS.RSPC series of recommendations is to provide a set of specifications for the radio interface(s) of FPLMTS, with sufficient detail to ensure that the overall goals of FPLMTS can be met. This series of recommendations is derived from the existing recommendation on principles, requirements, and framework for FPLMTS. The series includes protocols and procedures, physical layer, signalling and minimum performance requirements [and relevant test procedures and conditions]. The [RSPC series of Recommendations] differentiate, as far as possible, between the various layers of the FPLMTS radio protocol model for the transmission dependant parts of the radio interface(s).

24 The differentiation is intended to be an efficient means of providing the specifications to satisfy the likely divisions in the subsequent design processes. Transmission dependent parts of the radio interface(s) are specified in: RSPC.2 Radio interface [procedure] specification RSPC.3 Radio interface protocol specification RSPC.4 Mobile station and mobile earth station specification RSPC.5 Terrestrial base station specification The RSPC.1 Recommendation provides an overall specification outline for FPLMTS radio interface(s), traceability for the input parameters and the linkage between the [RSPC series of Recommendations]. [This Radio Interface Specifications Outline Recommendation is one of a number of Recommendations in the FPLMTS.RSPC series which defines the specifications for the radio interfaces of FPLMTS.]. Recommendation FPLMTS.RSPC.2 - Radio Interface [Procedures] Specification for FPLMTS This [chapter of the] Recommendation provides specification of the air interface [procedures] and characteristics that directly relate to the physical and some aspects of higher layers. In particular, it contains detailed descriptions of the functions that activate, configure and maintain the radio links, from the physical transmission of radio signals up to functions such as handover and radio resource management. [In addition, test procedures are specified which will ensure that mobile stations, or mobile earth stations, will operate with the required quality with their corresponding base stations in the FPLMTS network.] [This Radio Interface Procedure Specification Recommendation is one of a number of Recommendations in the RSPC series which defines the specifications for the radio interfaces of FPLMTS.] Recommendation FPLMTS.RSPC.3 - Radio Interface Protocol Specification for FPLMTS This [chapter of the] Recommendation gives the specific guidelines for the protocol layering used for structuring the radio interface functions of the radio subsystem. While the radio protocols include both transmission dependent and transmission independent signalling, and traverse the physical layer as well as some aspects of higher layers, this Recommendation only deals with transmission dependent aspects. [This Radio Interface Protocol Specification Recommendation is one of a number of Recommendations in the RSPC series which defines the specifications for the radio interfaces of FPLMTS.] Recommendation FPLMTS.RSPC.4 - Mobile Station and Mobile Earth Station Specification for FPLMTS This [chapter of the] Recommendation describes the specifications for the mobile and mobile earth station. It addresses only those essential elements necessary to ensure interoperability of equipment

25 from different manufacturers and to support global roaming capability, while allowing freedom of implementation to manufacturers to provide product differentiation. It addresses the topics of radio transmission and reception requirements, and global roaming requirements[, test conditions and procedures]. [This Mobile Station Specification Recommendation is one of a number of Recommendations in the RSPC series which defines the specifications for the radio interfaces of FPLMTS.] Recommendation FPLMTS.RSPC.5 - Terrestrial Base Station Specification for FPLMTS This [chapter of the] Recommendation describes the specifications for the terrestrial base station. It addresses only those essential elements necessary to ensure interoperability of equipment from different manufacturers and to support global roaming, while leaving manufacturers to choose the actual implementation and enhancements. The characteristics are divided into those common to transmission and reception, those specific to transmission, and those specific to reception. [In addition, test conditions and procedures are specified which will ensure that the terrestrial base station will operate with the required quality in the FPLMTS network.] [This Terrestrial Base Station Specification Recommendation is one of a number of Recommendations in the RSPC series which defines the specifications for the radio interfaces of FPLMTS.]
