Section: 5.8.13.2 NR sidelink discovery monitoring
Content: A UE capable of NR sidelink discovery that is configured by upper layers to monitor NR sidelink discovery messages shall: 1> if the frequency used for NR sidelink discovery is included in sl-FreqInfoToAddModList in RRCReconfiguration message and sl-DiscConfig is included in RRCReconfiguration; or if the frequency used for NR sidelink discovery is included in sl-FreqInfoList included in SIB12 and sl-DiscConfigCommon is included in SIB12: 2> if the UE is configured with sl-DiscRxPool for NR sidelink discovery reception included in RRCReconfiguration message with reconfigurationWithSync (i.e. handover): 3> configure lower layers to monitor sidelink control information and the corresponding data using the resource pool indicated by sl-DiscRxPool for NR sidelink discovery reception in RRCReconfiguration; 2> else if the UE is configured with sl-RxPool for NR sidelink discovery reception included in RRCReconfiguration message with reconfigurationWithSync (i.e. handover): 3> configure lower layers to monitor sidelink control information and the corresponding data using the resource pool indicated by sl-RxPool for NR sidelink discovery reception in RRCReconfiguration; 2> else if the cell chosen for NR sidelink discovery reception provides SIB12: 3> if sl-DiscRxPool for NR sidelink discovery reception is included in SIB12: 4> configure lower layers to monitor sidelink control information and the corresponding data using the resource pool indicated by sl-DiscRxPool for NR sidelink discovery reception in SIB12; 3> else if sl-RxPool for NR sidelink discovery reception is included in SIB12: 4> configure lower layers to monitor sidelink control information and the corresponding data using the resource pool indicated by sl-RxPool for NR sidelink discovery reception in SIB12; 1> else: 2> if out of coverage on the concerned frequency for NR sidelink discovery: 3> if sl-DiscRxPool was preconfigured: 4> configure lower layers to monitor sidelink control information and the corresponding data using the resource pool that was preconfigured by sl-DiscRxPool for NR sidelink discovery reception in SL-PreconfigurationNR, as defined in clause 9.3; 3> else: 4> configure lower layers to monitor sidelink control information and the corresponding data using the resource pool that was preconfigured by sl-RxPool for NR sidelink discovery reception in SL-PreconfigurationNR, as defined in clause 9.3; NOTE: If sl-DiscRxPool and sl-RxPool are both included in SIB12 or preconfigured, it is up to UE implementation whether to monitor sidelink control information and the corresponding data using the resource pool indicated by sl-RxPool for NR sidelink discovery reception.
