hical coordinates (0,0), length and width. The UE determines the zone identity by means of modulo operation using length and width of each zone, number of zones in length, number of zones in width, the single fixed reference point, and the geo- graphical coordinates of the UE's current location. The length and width of each zone, num- ber of zones in length, and number of zones in width are provided by the eNB when the UE is in-coverage, and preconfigured when the UE is out-of-coverage. The zone is configurable for both in-coverage and out-of-coverage. In an in-coverage scenario, when the UE uses autonomous resource selection, the eNB can provide the mapping between zone(s) and V2X sidelink transmission resource pools via RRC signaling. For out-of-coverage UEs, the map- ping between the zone(s) and V2X sidelink transmission resource pools can be preconfi- gured. If the mapping between zone(s) and V2X sidelink transmission resource pool is (pre- )configured, then the UE selects transmission sidelink resources from the resource pool cor- responding to the zone where it is presently located. The zone concept is not applied to exceptional V2X sidelink transmission pools as well as reception pools. Resource pools for V2X sidelink communication are not configured based on priority. For V2X sidelink transmission, during handover, transmission resource pool configurations including exceptional transmission resource pool for the target cell can be signaled in the handover command to minimize the transmission interruption. In this way, the UE may use the V2X sidelink transmission resource pools of the target cell before the handover is com- pleted, if either synchronization is performed with the target cell in case eNB is configured as synchronization source or synchronization is performed with GNSS in case GNSS is con- figured as synchronization source. If the exceptional transmission resource pool is included in the handover command, the UE uses randomly selected resources from the exceptional transmission resource pool,
