Method and apparatus for supporting vehicle to everything service
A method for supporting a vehicle communication (connected car or vehicle to everything (V2X)) service in a wireless communication system and an apparatus thereof are provided. The method includes receiving threshold information for reporting a channel busy ratio (CBR), measuring the CBR for a resource pool, identifying whether a reporting condition is satisfied by comparing the measured CBR with the threshold information, and reporting the measured CBR if the reporting condition is satisfied. The present disclosure relates to a communication technique for converging a fifth generation (5G) communication system for supporting higher data rates beyond a fourth generation (4G) system with an Internet of things (IoT) technology, and may be applied to intelligent services based on the 5G communication technology and the IoT-related technology.
1. A method by a base station for supporting a vehicle to everything (V2X) service, the method comprising:
transmitting a first message including first information on zone configuration, wherein the first information on the zone configuration includes zone-related information for identifying a zone and resource pool information corresponding to the zone identified based on the zone-related information;
receiving, from a terminal, a report message including a channel busy ratio (CBR) for a resource pool corresponding to the zone, wherein the resource pool is identified based on the resource pool information corresponding to the zone;
updating the zone configuration by adjusting a size of the zone based on the received CBR, and updating the resource pool information based on the updated zone configuration; and
transmitting a second message including second information on the updated zone configuration.
2. The method of claim 1 ,
wherein the zone is a defined area, and
wherein the zone-related information includes at least one of a width of a zone basic unit for deriving a zone identifier (ID) or a length of the zone basic unit.
3. The method of claim 1 , wherein the terminal is located in the zone.
4. The method of claim 1 , wherein the second message further includes the updated resource pool information.
5. A base station for supporting a vehicle to everything (V2X) service, the base station comprising:
a transceiver; and
a controller coupled with the transceiver and configured to control to:
transmit a first message including first information on zone configuration, wherein the first information on the zone configuration includes zone-related information for identifying a zone and resource pool information corresponding to the zone identified based on the zone-related information,
receive, from a terminal, a report message including a channel busy ratio (CBR) for a resource pool corresponding to the zone, wherein the resource pool is identified based on the resource pool information corresponding to the zone,
update the zone configuration by adjusting a size of the zone based on the received CBR, and update the resource pool information based on the updated zone configuration, and
transmit a second message including second information on the updated zone configuration.
6. The base station of claim 5 ,
wherein the zone is a defined area, and
wherein the zone-related information includes at least one of a width of a zone basic unit for deriving a zone identifier (ID) or a length of the zone basic unit.
7. The base station of claim 5 , wherein the terminal is located in the zone.
8. The base station of claim 5 , wherein the second message further includes the updated resource pool information.
9. A method by a terminal for supporting a vehicle to everything (V2X) service, the method comprising:
receiving, from a base station, a first message including first information on zone configuration, wherein the first information on the zone configuration includes zone-related information for identifying a zone and resource pool information corresponding to the zone identified based on the zone-related information;
transmitting, to the base station, a report message including a channel busy ratio (CBR) for a resource pool corresponding to the zone, wherein the resource pool is identified based on the resource pool information corresponding to the zone; and
receiving, from the base station, a second message including second information on an updated zone configuration which is updated by adjusting a size of the zone based on the CBR,
wherein the resource pool information is updated based on the updated zone configuration.
10. The method of claim 9 ,
wherein the zone is a defined area, and
wherein the zone-related information includes at least one of a width of a zone basic unit for deriving a zone identifier (ID) or a length of the zone basic unit.
11. The method of claim 9 , wherein the terminal is located in the zone.
12. The method of claim 9 , wherein the second message further includes the updated resource pool information.
13. A terminal for supporting a vehicle to everything (V2X) service, the terminal comprising:
a transceiver; and
a controller coupled with the transceiver and configured to control to:
receive, from a base station, a first message including first information on zone configuration, wherein the first information on the zone configuration includes zone-related information for identifying a zone and resource pool information corresponding to the zone identified based on the zone-related information,
transmit, to the base station, a report message including a channel busy ratio (CBR) for a resource pool corresponding to the zone, wherein the resource pool is identified based on the resource pool information corresponding to the zone, and
receive, from the base station, a second message including second information on an updated zone configuration which is updated by adjusting a size of the zone based on the CBR,
wherein the resource pool information is updated based on the updated zone configuration.
14. The terminal of claim 13 ,
wherein the zone is a defined area, and
wherein the zone-related information includes at least one of a width of a zone basic unit for deriving a zone identifier (ID) or a length of the zone basic unit.
15. The terminal of claim 13 , wherein the terminal is located in the zone.
16. The terminal of claim 13 , wherein the second message further includes the updated resource pool information.
