VEHICLE TERMINAL FOR CONTROLLING V2X MESSAGE TRANSMISSION BETWEEN VEHICLE TERMINALS THROUGH V2X SERVICE IN WIRELESS COMMUNICATION SYSTEM AND COMMUNICATION CONTROL METHOD THEREOF

Disclosed herein is a communication control method of a vehicle user equipment (UE) for controlling vehicle-to-everything (V2X) message transmission between vehicle UEs through a V2X service in a wireless communication system. The communication control method of the vehicle UE includes receiving a V2X message from a first external vehicle UE, determining whether the V2X message is transmitted to a second external vehicle UE located in a coverage area of the vehicle UE, based on relaying information indicating whether the V2X message is relayed, and transmitting the V2X message to the second external vehicle UE, upon determining that the V2X message is transmitted to the second external vehicle UE. The relaying information includes at least one of active status information, relay probability information or residual life information.
