1. A method for performing, by a first device, wireless communication, the method comprising:
obtaining sidelink (SL) discontinuous reception (DRX) configuration;
starting an SL DRX on-duration timer of the SL DRX configuration;
receiving first sidelink control information (SCI) for scheduling of a physical sidelink shared channel (PSSCH), from a second device, through a physical sidelink control channel (PSCCH);
receiving a medium access control (MAC) protocol data unit (PDU) and second SCI including a 16-bit layer (L)1 destination identifier (ID) and an 8-bit L1 source ID, from the second device, through the PSSCH;
comparing the L1 destination ID and a 16 least significant bit (LSB) of an L2 source ID of the first device;
comparing the L1 source ID and an 8 LSB of an L2 destination ID of the first device; and
starting an SL DRX inactivity timer of the SL DRX configuration, based on the L1 destination ID beingis the same as the 16 LSB of the L2 source ID, and the L1 source ID being the same as the 8 LSB of the L2 destination ID.
