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 a vehicle-to-X (V2X) transmission in a wireless communication system, the method performed by a user equipment (UE) and comprising:
determining a set of resources for the V2X transmission based on monitoring a monitoring duration; and
performing the V2X transmission based on the determined set of resources,
wherein the monitoring duration, on which the UE performs the monitoring, has a boundary of a time duration which is specific to the UE.
2. The method of claim 1 , wherein the monitoring duration is based on a subframe N which is specific to the UE, and
wherein the N is a positive integer number.
3. The method of claim 2 , wherein the monitoring duration is a duration from a subframe (N−A) to a subframe (N−B),
wherein the A is a positive integer number, and
wherein the B is a positive integer number and the B is smaller than the A.
4. A method for performing a vehicle-to-X (V2X) transmission in a wireless communication system, the method performed by a user equipment (UE) and comprising:
monitoring a monitoring duration;
selecting a V2X resource for the V2X transmission based on the monitoring; and
performing the V2X transmission based on the selected V2X resource,
wherein the selected V2X resource is within a time interval which fulfils a latency requirement, and
wherein the time interval is located after the monitoring duration.
5. The method of claim 4 , wherein the time interval is based on UE implementation.
6. The method of claim 4 , wherein the time interval is an interval from a subframe (M+T1) to a subframe (M+T2),
wherein the M is a positive integer number,
wherein the T1 is a positive integer number, and
wherein the T2 is a positive integer number.
7. The method of claim 4 , wherein the UE selects the V2X resource based on performing energy measurement based on a number of at least one sub channel used for transmitting the V2X message.
8. The method of claim 4 , wherein the monitoring duration, on which the UE performs the monitoring, has a boundary of a time duration which is specific to the UE.
9. The method of claim 8 , wherein the monitoring duration is based on a subframe N which is specific to the UE, and
wherein the N is a positive integer number.
10. The method of claim 9 , wherein the monitoring duration is a duration from a subframe (N−A) to a subframe (N−B),
wherein the A is a positive integer number, and
wherein the B is a positive integer number and the B is smaller than the A.
