Section: 5.3.5.16 L2 U2N or U2U Remote UE configuration
Content: The network configures the L2 U2N or U2U Remote UE with relay operation related configurations, e.g. SRAP configuration. The L2 U2N Remote UE shall: 1> if sl-L2RemoteUE-Config is set to setup or received from RRCSetup message: 2> if the sl-L2RemoteUE-Config contains the sl-SRAP-ConfigRemote: 3> if no SRAP entity has been established: 4> establish a SRAP entity as specified in TS 38.351[ NR; Sidelink Relay Adaptation Protocol (SRAP) Specification ]  [66]; 3> configure the parameters to SRAP entity in accordance with the sl-SRAP-ConfigRemote; 3> if SRB1 is included in sl-MappingToAddModList, and sl-EgressRLC-ChannelPC5 is configured: 4> release SL-RLC1, if established; 4> associate the PC5 Relay RLC channel as indicated by sl-EgressRLC-ChannelPC5 with SRB1; 3> else: (i.e. SRB1 is not included in sl-MappingToAddModList, or SRB1 is included in sl-MappingToAddModList, but sl-EgressRLC-ChannelPC5 is not configured) 4> if SL-RLC1 is not established: 5> apply the default configuration of SL-RLC1 as specified in clause 9.2.4 and associate it with the SRB1; 2> if the sl-L2RemoteUE-Config contains the sl-UEIdentityRemote: 3> use the value of the sl-UEIdentityRemote as the C-RNTI in the PCell. 1> else if sl-L2RemoteUE-Config is set to release: 2> release the relay operation related configurations. The L2 U2U Remote UE shall: 1> if sl-L2RemoteUE-Config is set to setup: 2> if the sl-L2RemoteUE-Config contains the sl-U2U-RelayUE-ToReleaseList: 3> perform the L2 U2U Relay UE release as specified in 5.3.5.16.1; 2> if the sl-L2RemoteUE-Config contains the sl-U2U-RelayUE-ToAddModList: 3> perform the L2 U2U Relay UE addition/modification as specified in 5.3.5.16.2; 1> else if sl-L2RemoteUE-Config is set to release: 2> release the related configurations.
