Method for providing V2X-related service by device in wireless communication system supporting sidelink, and device therefor

1. A method for providing a vehicle-to-everything (V2X) related service by a device including a plurality of distributed antennas in a wireless communication system supporting sidelink, the method comprising:

receiving a first signal through each of the plurality of distributed antennas; and

determining whether to transmit a second signal for providing the V2X related service,

wherein the plurality of distributed antennas comprises a first distributed antenna and a second distributed antenna distributed by a predetermined distance from each other, and

wherein the second signal is transmitted based on a difference between a first reception time at which the first signal is received through the first distributed antenna and a second reception time at which the first signal is received through the second distributed antenna being less than a threshold time.

2. The method of claim 1 , wherein the plurality of distributed antennas further comprises a third distributed antenna distributed by the predetermined distance from the second distributed antenna in a direction in which the first distributed antenna and the distribute second antenna are distributed.

3. The method of claim 2 , wherein the first reception time is determined by a reception time of a distributed antenna from which the first signal was received first among the first distributed antenna and the second distributed antenna.

4. The method of claim 2 , wherein the threshold time is set differently according to a distributed antenna receiving the first signal first among the first distributed antenna, the second distributed antenna, and the third distributed antenna.

5. The method of claim 2 , wherein the predetermined distance is predetermined based on a width of a road having the device positioned thereon.

6. The method of claim 2 , wherein a signal type of the second signal is determined based on a distributed antenna receiving the first signal first among the first distributed antenna, the second distributed antenna, and the third distributed antenna.

7. The method of claim 6 , wherein, on a basis that the first signal is first received through the second distributed antenna, the second signal is a warning signal notifying nearby vehicles of presence and danger of a pedestrian on a road.

8. The method of claim 6 , wherein, on a basis that the first signal is first received through the first distributed antenna or the third distributed antenna, the second signal is a control signal for controlling a signal of an adjacent traffic light.

9. The method of claim 6 , wherein, on a basis that the first signal is first received through the first distributed antenna or the third distributed antenna, the second signal is a signal indicating correction of VRU position information included in the first signal.

10. The method of claim 1 , wherein:

the first signal is a personal safety message (PSM) transmitted from a vulnerable road user (VRU); and

the device is a road side unit (RSU).

11. A device configured to provide a vehicle-to-everything (V2X) related service in a wireless communication system supporting sidelink, the device comprising:

a plurality of distributed antennas; and

a processor connected to the plurality of distributed antennas,

wherein the processor is configured to:

control the plurality of distributed antennas to receive a first signal through each of the plurality of distributed antennas;

calculate a reception time when the first signal is received through each of the plurality of distributed antennas; and

determine whether to transmit a second signal for providing the V2X related service based on the calculated reception time and a threshold time,

wherein the plurality of distributed antennas comprises a first distributed antenna and a second distributed antenna distributed by a predetermined distance from each other, and

wherein the second signal is transmitted based on a difference between a first reception time at which the first signal is received through the first distributed antenna and a second reception time at which the first signal is received through the second distributed antenna being less than the threshold time.

12. A chipset configured to provide a vehicle-to-everything (V2X) related service in a wireless communication system supporting sidelink, the chipset comprising:

at least one processor; and

at least one memory operatively coupled to the at least one processor and configured to cause, when executed, the at least one processor to perform operations comprising:

receiving a first signal through each of a plurality of distributed antennas;

calculating a reception time when the first signal is received through each of the plurality of distributed antennas; and

determining whether to transmit a second signal for providing the V2X related service based on the calculated reception time and a threshold time,

wherein the plurality of distributed antennas comprises a first distributed antenna and a second distributed antenna distributed by a predetermined distance from each other, and

wherein the second signal is transmitted based on a difference between a first reception time at which the first signal is received through the first distributed antenna and a second reception time at which the first signal is received through the second distributed antenna being less than the threshold time.
