There are also (parts of) procedures and messages which are only applicable to the RN in its communication with the E-UTRAN, in which case the specification denotes the RN instead of the UE. Such RN-specific aspects are not applicable to the UE.

21 21 TS V ( ) This specification is organised as follows: - sub-clause 4.2 describes the RRC protocol model; - sub-clause 4.3 specifies the services provided to upper layers as well as the services expected from lower layers; - sub-clause 4.4 lists the RRC functions; - clause 5 specifies RRC procedures, including UE state transitions; - clause 6 specifies the RRC message in a mixed format (i.e. tabular & ASN.1 together); - clause 7 specifies the variables (including protocol timers and constants) and counters to be used by the UE; - clause 8 specifies the encoding of the RRC messages; - clause 9 specifies the specified and default radio configurations; - clause 10 specifies the RRC messages transferred across network nodes; - clause 11 specifies the UE capability related constraints and performance requirements. 4.2 Architecture UE states and state transitions including inter RAT A UE is in RRC_CONNECTED when an RRC connection has been established. If this is not the case, i.e. no RRC connection is established, the UE is in RRC_IDLE state. The RRC states can further be characterised as follows: - RRC_IDLE: - A UE specific DRX may be configured by upper layers. - UE controlled mobility; - The UE: - Monitors a Paging channel to detect incoming calls, system information change, for ETWS capable UEs, ETWS notification, and for CMAS capable UEs, CMAS notification; - Performs neighbouring cell measurements and cell (re-)selection; - Acquires system information. - Performs logging of available measurements together with location and time for logged measurement configured UEs. - RRC_CONNECTED: - Transfer of unicast data to/from UE. - At lower layers, the UE may be configured with a UE specific DRX. - For UEs supporting CA, use of one or more SCells, aggregated with the PCell, for increased bandwidth; - Network controlled mobility, i.e. handover and cell change order with optional network assistance (NACC) to GERAN; - The UE: - Monitors a Paging channel and/ or System Information Block Type 1 contents to detect system information change, for ETWS capable UEs, ETWS notification, and for CMAS capable UEs, CMAS notification; - Monitors control channels associated with the shared data channel to determine if data is scheduled for it;

22 22 TS V ( ) - Provides channel quality and feedback information; - Performs neighbouring cell measurements and measurement reporting; - Acquires system information. The following figure not only provides an overview of the RRC states in E-UTRA, but also illustrates the mobility support between E-UTRAN, UTRAN and GERAN.

The details of the CDMA2000 state models are out of the scope of this specification. 1xRTT CS Active Handover E-UTRA RRC CONNECTED Handover HRPD Dormant HRPD Active Connection establishment/release 1xRTT Dormant Reselection E-UTRA RRC IDLE Reselection HRPD Idle Figure : Mobility procedures between E-UTRA and CDMA2000 The inter-rat handover procedure(s) supports the case of signalling, conversational services, non-conversational services and combinations of these. In addition to the state transitions shown in Figure and Figure , there is support for connection release with redirection information from E-UTRA RRC_CONNECTED to GERAN, UTRAN and CDMA2000 (HRPD Idle/ 1xRTT Dormant mode).

23 23 TS V ( ) Signalling radio bearers "Signalling Radio Bearers" (SRBs) are defined as Radio Bearers (RB) that are used only for the transmission of RRC and NAS messages. More specifically, the following three SRBs are defined: - SRB0 is for RRC messages using the CCCH logical channel; - SRB1 is for RRC messages (which may include a piggybacked NAS message) as well as for NAS messages prior to the establishment of SRB2, all using DCCH logical channel; - SRB2 is for RRC messages which include logged measurement information as well as for NAS messages, all using DCCH logical channel. SRB2 has a lower-priority than SRB1 and is always configured by E-UTRAN after security activation. In downlink piggybacking of NAS messages is used only for one dependant (i.e. with joint success/ failure) procedure: bearer establishment/ modification/ release. In uplink NAS message piggybacking is used only for transferring the initial NAS message during connection setup. NOTE: The NAS messages transferred via SRB2 are also contained in RRC messages, which however do not include any RRC protocol control information. Once security is activated, all RRC messages on SRB1 and SRB2, including those containing NAS or non- messages, are integrity protected and ciphered by PDCP. NAS independently applies integrity protection and ciphering to the NAS messages. 4.3 Services Services provided to upper layers The RRC protocol offers the following services to upper layers: - Broadcast of common control information; - Notification of UEs in RRC_IDLE, e.g. about a terminating call, for ETWS, for CMAS; - Transfer of dedicated control information, i.e. information for one specific UE Services expected from lower layers In brief, the following are the main services that RRC expects from lower layers: - PDCP: integrity protection and ciphering; - RLC: reliable and in-sequence transfer of information, without introducing duplicates and with support for segmentation and concatenation. Further details about the services provided by Packet Data Convergence Protocol layer (e.g. integrity and ciphering) are provided in TS [8]. The services provided by Radio Link Control layer (e.g. the RLC modes) are specified in TS [7]. Further details about the services provided by Medium Access Control layer (e.g. the logical channels) are provided in TS [6]. The services provided by physical layer (e.g. the transport channels) are specified in TS [3]. 4.4 Functions The RRC protocol includes the following main functions: - Broadcast of system information: - Including NAS common information;

24 24 TS V ( ) - Information applicable for UEs in RRC_IDLE, e.g. cell (re-)selection parameters, neighbouring cell information and information (also) applicable for UEs in RRC_CONNECTED, e.g. common channel configuration information. - Including ETWS notification, CMAS notification; - RRC connection control: - Paging; - Establishment/ modification/ release of RRC connection, including e.g. assignment/ modification of UE identity (C-RNTI), establishment/ modification/ release of SRB1 and SRB2, access class barring; - Initial security activation, i.e. initial configuration of AS integrity protection (SRBs) and AS ciphering (SRBs, DRBs); - For RNs, configuration of AS integrity protection for DRBs; - RRC connection mobility including e.g. intra-frequency and inter-frequency handover, associated security handling, i.e. key/ algorithm change, specification of RRC context information transferred between network nodes; - Establishment/ modification/ release of RBs carrying user data (DRBs); - Radio configuration control including e.g. assignment/ modification of ARQ configuration, HARQ configuration, DRX configuration; - For RNs, RN-specific radio configuration control for the radio interface between RN and E-UTRAN; - In case of CA, cell management including e.g. change of PCell, addition/ modification/ release of SCell(s) and addition/modification/release of STAG(s); - QoS control including assignment/ modification of semi-persistent scheduling (SPS) configuration information for DL and UL, assignment/ modification of parameters for UL rate control in the UE, i.e. allocation of a priority and a prioritised bit rate (PBR) for each RB; - Recovery from radio link failure; - Inter-RAT mobility including e.g. security activation, transfer of RRC context information; - Measurement configuration and reporting: - Establishment/ modification/ release of measurements (e.g. intra-frequency, inter-frequency and inter- RAT measurements); - Setup and release of measurement gaps; - Measurement reporting; - Other functions including e.g. transfer of dedicated NAS information and non- dedicated information, transfer of UE radio access capability information, support for E-UTRAN sharing (multiple PLMN identities); - Generic protocol error handling; - Support of self-configuration and self-optimisation; - Support of measurement logging and reporting for network performance optimisation [60]; NOTE: Random access is specified entirely in the MAC including initial transmission power estimation.

25 25 TS V ( ) 5 Procedures 5.1 General Introduction The procedural requirements are structured according to the main functional areas: system information (5.2), connection control (5.3), inter-rat mobility (5.4) and measurements (5.5). In addition sub-clause 5.6 covers other aspects e.g. NAS dedicated information transfer, UE capability transfer, sub-clause 5.7 specifies the generic error handling, subclause 5.8 covers MBMS and sub-clause 5.9 covers RN-specific procedures General requirements The UE shall: 1> process the received messages in order of reception by RRC, i.e. the processing of a message shall be completed before starting the processing of a subsequent message; NOTE 1: E-UTRAN may initiate a subsequent procedure prior to receiving the UE's response of a previously initiated procedure. 1> within a sub-clause execute the steps according to the order specified in the procedural description; 1> consider the term 'radio bearer' (RB) to cover SRBs and DRBs but not MRBs unless explicitly stated otherwise; 1> set the rrc-transactionidentifier in the response message, if included, to the same value as included in the message received from E-UTRAN that triggered the response message; 1> upon receiving a choice value set to setup: 2> apply the corresponding received configuration and start using the associated resources, unless explicitly specified otherwise; 1> upon receiving a choice value set to release: 2> clear the corresponding configuration and stop using the associated resources; 1> upon handover to E-UTRA; or 1> upon receiving an RRCConnectionReconfiguration message including the fullconfig: 2> apply the Conditions in the ASN.1 for inclusion of the fields for the DRB/PDCP/RLC setup during the reconfiguration of the DRBs included in the drb-toaddmodlist; NOTE 2: At each point in time, the UE keeps a single value for each field except for during handover when the UE temporarily stores the previous configuration so it can revert back upon handover failure. In other words: when the UE reconfigures a field, the existing value is released except for during handover. NOTE 3: Although not explicitly stated, the UE initially considers all functionality to be deactivated/ released until it is explicitly stated that the functionality is setup/ activated. Correspondingly, the UE initially considers lists to be empty e.g. the list of radio bearers, the list of measurements.
