Patent ID: 11115790

Abstract:
A method for performing a V2X communication in a wireless communication system and a device therefor are disclosed. A method for performing, by a user equipment (UE), a vehicle-to-everything (V2X) communication in a wireless communication system includes receiving a transmission request of a V2X message from an upper layer, when receiving the transmission request of the V2X message, selecting a resource for the V2X communication over a PC5 interface if the UE is ‘Not served by evolved universal terrestrial radio access network (E-UTRAN) for V2X communication’, and performing a transmission for the V2X communication over the PC5 interface. If the UE is camped on a cell supporting the V2X communication, and a carrier frequency provided by the cell on which the UE is camped does not belong to a pre-configured carrier frequency the UE intends to use, the UE is considered as ‘Not served by E-UTRAN for V2X communication’.
