24.1.9.1 Test Purpose (TP)

(1)

with { UE is authorized for performing V2X sidelink Communication, and UE is out of coverage on the frequency used for V2X sidelink communication, and UE cannot find a cell which provides inter-frequency V2X configuration (i.e. the frequency used to transmit V2X sidelink communication is not included in v2x-InterFreqInfoList in RRCConnectionReconfiguration or in v2x-InterFreqInfoList within SystemInformationBlockType21 or SystemInformationBlockType21 is not broadcasted or there is not suitable cell) on the anchor carrier frequency as the one pre-configured in the UE/USIM and broadcasted in SystemInformationBlockType21 }

ensure that {

when { UE is triggered by an upper layer application to transmit V2X sidelink communication, and, zoneConfig is included in SL-V2X-Preconfiguration }

then { UE transmits V2X sidelink communication using the resources in the resource pool which pre-configured with zoneID equal to the zone identity determined by UE geographical coordinate }

}

24.1.9.2 Conformance requirements

References: The conformance requirements covered in the current TC are specified in: TS 36.331 subclause 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 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;

The UE shall determine an identity of the zone (i.e. Zone_id) in which it is located using the following formulae, if zoneConfig is included in SystemInformationBlockType21 or in SL-V2X-Preconfiguration:

x1= Floor (x / L) Mod Nx;

y1= Floor (y / W) Mod Ny;

Zone_id = y1 * Nx + x1.

The parameters in the formulae are defined as follows:

L is the value of zoneLength included in zoneConfig in SystemInformationBlockType21 or in SL-V2X-Preconfiguration;

W is the value of zoneWidth included in zoneConfig in SystemInformationBlockType21 or in SL-V2X-Preconfiguration;

Nx is the value of zoneIdLongiMod included in zoneConfig in SystemInformationBlockType21 or in SL-V2X-Preconfiguration;

Ny is the value of zoneIdLatiMod included in zoneConfig in SystemInformationBlockType21 or in SL-V2X-Preconfiguration;

x is the distance in longitude between UE’s current location and geographical coordinates (0, 0) and it is expressed in meters;

y is the distance in latitude between UE’s current location and geographical coordinates (0, 0) and it is expressed in meters.

The UE shall select a pool of resources which includes a zoneID equals to the Zone_id calculated according to above mentioned formulae and indicated by v2x-CommTxPoolNormalDedicated, v2x-CommTxPoolNormalCommon, v2x-CommTxPoolNormal in v2x-InterFreqInfoList or p2x-CommTxPoolNormal in v2x-InterFreqInfoList in RRCConnectionReconfiguration, or v2x-CommTxPoolList according to 5.10.13.1.

NOTE 1: The UE uses its latest geographical coordinates to perform resource pool selection.
