Abstract
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, in a selection period, a subframe excluding a subframe relating to a subframe in which transmission has been performed during a sensing period; and performing a V2X communication on the basis of the selected subframe.
Claims10
A method of performing a sidelink operation in a wireless communication system, the method performed by a user equipment (UE) and comprising:
- determining a sidelink resource set based on a candidate resource set and a candidate resource,
- wherein the candidate resource is excluded from the candidate resource set,
- wherein a time unit index of the candidate resource is determined based on a time unit index of a specific time unit in which the sidelink operation is performed within a sensing window of the UE;
- and
- performing the sidelink operation based on the sidelink resource set,
- wherein the time unit index of the candidate resource is Y,
- wherein the time unit index of the specific time unit is M,
- wherein the candidate resource is determined based on Y and M satisfying a condition that:
- Y+J*P
- =
- M+I
- ,
- wherein ∗ represents multiplication,
- wherein the J is at least one integer value of from 0 to a Cresel-1,
- wherein the Cresel is a positive integer related to a resource reselection counter,
- wherein the P is a value related to a first resource reservation interval, and
- wherein the I is a value related to a second resource reservation interval.
A User Equipment (UE) configured to perform a sidelink operation in a wireless communication system, the UE comprising:
- a transceiver;
- at least one processor;
- and
- at least one computer memory operably connectable to the at least one processor and storing instructions that, when executed by the at least one processor, perform operations comprising:
- determining a sidelink resource set based on a candidate resource set and a candidate resource,
- wherein the candidate resource is excluded from the candidate resource set,
- wherein a time unit index of the candidate resource is determined based on a time unit index of a specific time unit in which the sidelink operation is performed within a sensing window of the UE, and
- performing the sidelink operation based on the sidelink resource set,
- wherein the time unit index of the candidate resource is Y,
- wherein the time unit index of the specific time unit is M,
- wherein the candidate resource is determined based on Y and M satisfying a condition that:
- Y+J*P
- =
- M+N*I
- ,
- wherein ∗ represents multiplication,
- wherein the J is at least one integer value of from 0 to a Cresel-1,
- wherein the Cresel is a positive integer related to a resource reselection counter,
- wherein the P is a value related to a first resource reservation interval, and
- wherein the I is a value related to a second resource reservation interval.
An apparatus configured to control a User Equipment (UE) to perform a sidelink operation in a wireless communication system, the apparatus comprising:
- at least one processor;
- and
- at least one computer memory operably connectable to the at least one processor and storing instructions that, when executed by the at least one processor, perform operations comprising:
- determining a sidelink resource set based on a candidate resource set and a candidate resource,
- wherein the candidate resource is excluded from the candidate resource set,
- wherein a time unit index of the candidate resource is determined based on a time unit index of a specific time unit in which the sidelink operation is performed within a sensing window of the UE;
- and
- performing the sidelink operation based on the sidelink resource set,
- wherein the time unit index of the candidate resource is Y,
- wherein the time unit index of the specific time unit is M,
- wherein the candidate resource is determined based on Y and M satisfying a condition that:
- Y+J*P
- =
- M+N*I
- ,
- wherein ∗ represents multiplication,
- wherein the J is at least one integer value of from 0 to a Cresel-1,
- wherein the Cresel is a positive integer related to a resource reselection counter,
- wherein the P is a value related to a first resource reservation interval, and
- wherein the I is a value related to a second resource reservation interval.
