METHOD FOR SELECTING RESOURCE TO BE USED FOR PERFORMING V2X COMMUNICATION WITHIN RANGE SATISFYING LATENCY REQUIREMENT IN WIRELESS COMMUNICATION SYSTEM, AND TERMINAL USING SAME
The present invention provides a vehicle-to-X (V2X) operation method performed by a V2X terminal in a wireless communication system, the method comprising: selecting a resource to be used for performing a V2X communication within a range satisfying a latency requirement; and performing a V2X communication on the basis of the selected resource.
1 . A method for performing vehicle-to-x (V2X) operation in a wireless communication system, the method performed by a V2X user equipment (UE) and comprising:
selecting a resource to perform V2X communication within a duration satisfying a latency requirement; and
performing the V2X communication based on the selected resource.
2 . The method of claim 1 , wherein the V2X UE selects the resource based on configuring a selection window within the duration satisfying the latency requirement.
3 . The method of claim 2 , wherein the V2X communication is performed based on a unit of a plurality of subchannels, and
wherein the resource to perform V2X communication is selected based on sensing performed the unit of the plurality of subchannels.
4 . The method of claim 3 , wherein a sensing duration used for sensing is a duration having a size corresponding to a size of the plurality of subchannels.
5 . The method of claim 3 , wherein the V2X UE performs sensing based on an energy measurement average value of subchannels included in the plurality of subchannels.
6 . A method for performing a vehicle-to-x (V2X) in a wireless communication system, the method performed by a V2X user equipment (UE) and comprising:
selecting a resource to perform a V2X message transmission by performing sensing on a subchannel basis having a size corresponding to a size of subchannels used for the V2X message transmission; and
performing the V2X message transmission based on the selected resource.
7 . The method of claim 6 , wherein the V2X UE selects the resource based on configuring a selection window within the duration satisfying the latency requirement.
8 . The method of claim 7 , wherein a sensing duration used for sensing is a duration having a size corresponding to a size of the plurality of subchannels.
9 . The method of claim 8 , wherein the V2X UE performs sensing based on an energy measurement average value of subchannels included in the plurality of subchannels.
10 . A user equipment (UE) comprising:
a radio frequency (RF) unit that transmits and receives a radio signal; And
a processor coupled to the RF unit, wherein the processor is configured to:
select a resource to perform V2X communication within a duration satisfying a latency requirement; and
perform the V2X communication based on the selected resource.
