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 performed by a terminal in a wireless communication system, the method comprising:

receiving, from a base station, a message including zone-related information;

identifying a zone where the terminal is located in based on a location of the terminal and zone-related information;

selecting a resource pool corresponding to the zone based on resource pool information;

transmitting a data on the resource pool;

receiving, from the base station, threshold information for reporting a channel busy ratio (CBR), the threshold information including a first threshold or a second threshold;

measuring the CBR on resource pools in the resource pool information; and

reporting, to the base station, the CBR for the resource pools based on the threshold information.

2. The method of claim 1, wherein the reporting the CBR comprises:

reporting, to the base station, the CBR in case that threshold information includes the first threshold and the measured CBR is above the first threshold; and

reporting to the base station, the CBR in case that threshold information includes the second threshold and the measured CBR is below the second threshold.

3. The method of claim 1, further comprising at least one of:

identifying whether the CBR is above the first threshold;

or

identifying whether the CBR is below the second threshold.

4. The method of claim 1,

wherein the message further includes at least one of the resource pool information or threshold information for measuring the CBR, and

wherein the CBR for resource pools is measured based on the threshold information for measuring the CBR.

5. The method of claim 1, wherein the message includes at least one of a system information block (SIB) message, a radio resource control (RRC) connection reconfiguration message, or a pre-configuration message.

6. The method of claim 1, further comprising:

receiving, from the base station, transmission power information for transmitting data.

7. A terminal in a wireless communication system, the terminal comprising:

a transceiver; and

at least one processor configured to;

receive, from a base station via the transceiver, a message including zone-related information,

identify a zone where the terminal is located in based on a location of the terminal and zone-related information,

select a resource pool corresponding to the zone based on resource pool information,

via the transceiver, a data on the resource pool,

receive, from the base station via the transceiver, threshold information for reporting a channel busy ratio (CBR), the threshold information including a first threshold or a second threshold,

measure the CBR on resource pools in the resource pool information, and

report, to the base station via the transceiver, the CBR for the resource pools based on the threshold information.

8. The terminal of claim 7, wherein the at least one processor is further configured to:

report, to the base station via the transceiver, the CBR in case that threshold information includes the first threshold and the measured CBR is above the first threshold, and

report to the base station via the transceiver, the CBR in case that threshold information includes the second threshold and the measured CBR is below the second threshold.

9. The terminal of claim 7, wherein the at least one processor is further configured to perform at least one of:

identifying whether the CBR is above the first threshold, or

identifying whether the CBR is below the second threshold.

10. The terminal of claim 7, wherein the message further includes at least one of the resource pool information or threshold information for measuring the CBR.

11. The terminal of claim 10, wherein the CBR for resource pools is measured based on the threshold information for measuring the CBR.

12. The terminal of claim 7, wherein the message includes at least one of a system information block (SIB) message, a radio resource control (RRC) connection reconfiguration message, or a pre-configuration message.

13. The terminal of claim 7, wherein the at least one processor is further configured to receive, from the base station via the transceiver, transmission power information for transmitting data.
