1. A method for performing, by a first device, wireless communication, the method comprising:
obtaining information related to a resource pool;
obtaining a sidelink (SL) discontinuous reception (DRX) configuration including information related to a SL DRX cycle and information related to a plurality of timers including a first timer for a first SL DRX active time and a second timer for a second SL DRX active time;
generating a medium access control (MAC) protocol data unit (PDU) related to groupcast communication; and
selecting at least one SL resource for a transmission of the MAC PDU among a plurality of candidate resources in the resource pool, based on sensing,
wherein a first SL resource included in the at least one SL resource is included in the first SL DRX active time,
wherein the first SL resource being selected outside the first SL DRX active time is not allowed, based on the MAC PDU being related to groupcast transmission,
wherein at least one second SL resource included in the at least one SL resource is included in the first SL DRX active time or the second SL DRX active time, and
wherein the second timer is not running at the time of selecting the at least one SL resource.
