10. A user equipment (UE) for sidelink communication, comprising:
a processor; and
a transceiver for communicating with at least one terminal,
wherein the processor is executed to perform:
configuring a first resource sensing window for identifying whether resources of a candidate resource set to be used for sidelink DRX communication are reserved or used;
identifying whether the resources of the candidate resource set are reserved or used based on the first resource sensing window through the transceiver;
determining a selected resource set based on a result of the identification;
configuring a second resource sensing window for identifying whether resources of the selected resource set to be used for sidelink DRX communication are reserved or used, wherein the second resource sensing window is configured within a DRX inactive time based on information on a DRX active time of a receiving terminal, which is received from the receiving terminal;
identifying whether the resources of the candidate resource set are reserved or used by another terminal based on the second resource sensing window through the transceiver;
updating the selected resource set based on a result of the identification on the second resource sensing window; and
transmitting data to the receiving terminal through the transceiver by using a resource of the updated selected resource set.
