24.1.17.2 Conformance requirements

References: The conformance requirements covered in the current TC are specified in: TS 36.331, clauses 5.10.13.2.

[TS 36.331, clause 5.10.13.2]

For a frequency used for V2X sidelink communication, if zoneConfig is not ignored as specified in 5.10.13.1, the UE configured by upper layers for V2X sidelink communication shall only use the pool which corresponds to geographical coordinates of the UE, if zoneConfig is included in SystemInformationBlockType21 of the serving cell (RRC_IDLE)/ PCell (RRC_CONNECTED) or in RRCConnectionReconfiguration for the concerned frequency, and the UE is configured to use resource pools provided by RRC signalling for the concerned frequency; or if zoneConfig is included in SL-V2X-Preconfiguration for the concerned frequency, and the UE is configured to use resource pools in SL-V2X-Preconfiguration for the frequency, according to 5.10.13.1. The UE shall only use the pool which is associated with the synchronization reference source selected in accordance with 5.10.8.2.

1> if the UE is configured to transmit on p2x-CommTxPoolNormalCommon or on p2x-CommTxPoolNormal in v2x-InterFreqInfoList in SystemInformationBlockType21 according to 5.10.13.1; or

1> if the UE is configured to transmit on p2x-CommTxPoolList-r14 in SL-V2X-Preconfiguration according to 5.10.13.1; or

1> if zoneConfig is not included in SystemInformationBlockType21 and the UE is configured to transmit on v2x-CommTxPoolNormalCommon or v2x-CommTxPoolNormalDedicated; or

1> if zoneConfig is included in SystemInformationBlockType21 and the UE is configured to transmit on v2x-CommTxPoolNormalDedicated for P2X related V2X sidelink communication and zoneID is not included in v2x-CommTxPoolNormalDedicated; or

1> if zoneConfig is not included in the entry of v2x-InterFreqInfoList for the concerned frequency and the UE is configured to transmit on v2x-CommTxPoolNormal in v2x-InterFreqInfoList or p2x-CommTxPoolNormal in v2x-InterFreqInfoList in RRCConnectionReconfiguration; or

1> if zoneConfig is not included in SL-V2X-Preconfiguration for the concerned frequency and the UE is configured to transmit on v2x-CommTxPoolList in SL-V2X-Preconfiguration for the concerned frequency:

2> select the first pool associated with the synchronization reference source selected in accordance with 5.10.8.2;

1> if zoneConfig is included in SystemInformationBlockType21 and the UE is configured to transmit on v2x-CommTxPoolNormalCommon or v2x-CommTxPoolNormalDedicated for non-P2X related V2X sidelink communication; or

1> if zoneConfig is included in SystemInformationBlockType21 and the UE is configured to transmit on v2x-CommTxPoolNormalDedicated for P2X related V2X sidelink communication and zoneID is included in v2x-CommTxPoolNormalDedicated; or

1> if zoneConfig is included in the entry of v2x-InterFreqInfoList for the concerned frequency and the UE is configured to transmit on v2x-CommTxPoolNormal in v2x-InterFreqInfoList or p2x-CommTxPoolNormal in v2x-InterFreqInfoList in RRCConnectionReconfiguration; or

1> if zoneConfig is included in SL-V2X-Preconfiguration for the concerned frequency and the UE is configured to transmit on v2x-CommTxPoolList in SL-V2X-Preconfiguration for the concerned frequency:

2> select the pool configured with zoneID equal to the zone identity determined below and associated with the synchronization reference source selected in accordance with 5.10.8.2;
