Abstract

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.

Claims

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.
