Method and apparatus for performing V2X communication
Provided are a method for performing vehicle to everything (V2X) communication by a base station in a wireless communication system, and an apparatus for supporting the same. The base station receives resource information, which is used by a neighbor base station for V2X communication, from the neighbor base station, and determines whether to perform one of PC5 handover and Uu handover with respect to a terminal on the basis of the resource information used for V2X communication, wherein the resource information that the neighbor base station uses for V2X communication includes at least one of PC5 resource information and Uu resource information, which is used by the neighbor base station for V2X communication, and the PC5 handover may be performed using a PC5 resource of the neighbor base station and the Uu handover may be performed using a Uu resource of the neighbor base station.
1. A method performed by a base station (BS) in a wireless communication system, the method comprising:
allocating, to a user equipment (UE), a PC5 resource to perform vehicle to everything (V2X) communication;
receiving, from a neighbor BS, by a Resource Status Reporting procedure or a Load Indication procedure, resource information used for the V2X communication by the neighbor BS, wherein the resource information includes an occupancy rate of the PC5 resource and an occupancy rate of a Uu resource used by the neighbor BS for the V2X communication; and
performing a Uu handover to the neighbor BS for the UE, which moves to the neighbor BS from the BS, based on the received resource information used for the V2X communication,
wherein the Uu handover is performed using a Uu resource of the neighbor BS, and
wherein each of the BS and the neighbor BS is a BS for supporting switching between a PC5-based V2X operation and a Uu-based V2X operation.
2. The method of claim 1 , wherein the resource information includes at least one of a number of UEs using the PC5 resource to transmit the V2X message from the neighbor BS or a number of UEs using the Uu resource to transmit the V2X message from the neighbor BS.
3. The method of claim 1 , wherein the resource information includes at least one of a location of the PC5 resource used for the V2X communication by the neighbor BS or a location of the Uu resource used for the V2X communication by the neighbor BS.
4. The method of claim 1 , wherein the resource information includes at least one of a usage amount of the PC5 resource used for the V2X communication by the neighbor BS or a usage amount of the Uu resource used for the V2X communication by the neighbor BS.
5. The method of claim 1 , wherein the resource information includes a status of a load used for the V2X communication by the neighbor BS.
6. The method of claim 5 , wherein the status of a load is one of a low load status, an intermediate load state, or a high load state.
7. A method performed by a base station (BS) in a wireless communication system, the method comprising:
allocating, to a user equipment (UE), a Uu resource to perform vehicle to everything (V2X) communication;
receiving, from a neighbor BS, by a Resource Status Reporting procedure or a Load Indication procedure, resource information used for the V2X communication by the neighbor BS, wherein the resource information includes an occupancy rate of the PC5 resource and an occupancy rate of the Uu resource used by the neighbor BS for the V2X communication;
performing a PC5 handover to the neighbor BS for the UE, which moves to the neighbor BS from the BS, based on the resource information used for the V2X communication; and
wherein the PC5 handover is performed using a PC5 resource of the neighbor BS, and
wherein each of the base station and the neighbor base station is a base station for supporting switching between a PC5-based V2X operation and a Uu-based V2X operation.
