Method and device for performing communication in wireless communication system

1. A method by which a first terminal performs communication in a wireless communication system, the method comprising:

receiving, from a base station, risk area information including synchronization signal block (SSB) identification information corresponding to a risk area;

performing SSB measurement for at least one SSB received from the base station;

identifying an SSB among the at least one SSB, based on the SSB measurement;

in case that the first terminal is located in the risk area, obtaining pedestrian-to-vehicle (P2V) data based on the SSB identification information corresponding to the identified SSB; and

transmitting, to a second terminal, the P2V data, on a resource allocated to the first terminal by the base station.

2. The method of claim 1 , further comprising:

in case that the risk area information comprises location information of the risk area,

determining whether the first terminal is located in the risk area, by comparing the location information of the risk area with location information of the first terminal.

3. The method of claim 1 ,

wherein the identifying the SSB among the at least one SSB comprises:

identifying the SSB in which a reference signal received power (RSRP) exceeds a threshold value, based on the SSB measurement.

4. The method of claim 1 , wherein the receiving of the risk area information comprises receiving the risk area information through at least one of system information, a paging signal, and a short message.

5. The method of claim 4 , wherein the receiving of the risk area information comprises:

obtaining the SSB identification information corresponding to the risk area from the system information or the paging signal; and

receiving a short message indicating that the first terminal is located in the risk area in an area covered by the SSB corresponding to the risk area.

6. A method by which a base station performs communication in a wireless communication system, the method comprising:

transmitting risk area information including synchronization signal block (SSB) identification information corresponding to a risk area;

transmitting at least one synchronization signal block (SSB);

in case that a first terminal is located in the risk area, receiving a pedestrian-to-vehicle (P2V) transmission resource allocation request from the first terminal based on the at least one SSB and the SSB identification information corresponding to the risk area; and

allocating a P2V transmission resource to the first terminal, based on the P2V transmission resource allocation request.

7. The method of claim 6 , wherein the transmitting of the risk area information comprises transmitting the risk area information through at least one of a paging signal and a short message to a cover area of the SSB corresponding to the risk area.

8. A first terminal for performing communication in a wireless communication system, the first terminal comprising:

a transceiver; and

a processor coupled with the transceiver and configured to:

receive, from a base station, risk area information including synchronization signal block (SSB) identification information corresponding to a risk area,

perform SSB measurement for at least one SSB received from the base station,

identify an SSB among the at least one SSB, based on the SSB measurement,

in case that the first terminal is located in the risk area, obtain pedestrian-to-vehicle (P2V) data based on the identified SSB and the SSB identification information corresponding to the risk area, and

transmit, to a second terminal, the P2V data, on a resource allocated to the first terminal by the base station.

9. The first terminal of claim 8 , wherein the risk area information is information indicating whether the first terminal is located in the risk area.

10. The first terminal of claim 8 ,

wherein the processor is further configured to, in case that the risk area information comprises location information of the risk area, determine whether the first terminal is located in the risk area, by comparing the location information of the risk area with location information of the first terminal.

11. The first terminal of claim 8 , wherein the processor is further configured to identify the SSB in which a reference signal received power (RSRP) exceeds a threshold value, based on the SSB measurement.

12. The first terminal of claim 8 , wherein the processor is further configured to control the transceiver to receive the risk area information through at least one of system information, a paging signal, and a short message.

13. The first terminal of claim 12 , wherein the processor is further configured to:

obtain the SSB identification information corresponding to the risk area from the system information or the paging signal; and

control the transceiver to receive a short message indicating that the first terminal is located in the risk area in an area covered by the SSB corresponding to the risk area.

14. A base station for performing communication in a wireless communication system, the base station comprising:

a transceiver; and

a processor coupled with the transceiver and configured to:

control the transceiver to transmit risk area information including synchronization signal block (SSB) identification information corresponding to a risk area,

transmit at least one synchronization signal block (SSB),

in case that a first terminal is located in the risk area, receive a pedestrian-to-vehicle (P2V) transmission resource allocation request from the first terminal based on the at least one SSB and the SSB identification information corresponding to the risk area, and

allocate a P2V transmission resource to the first terminal, based on the P2V transmission resource allocation request.
