1. A method for performing wireless communication by a first device, the method comprising:
receiving, from a second device, a physical sidelink control channel (PSCCH);
receiving, from the second device, a physical sidelink shared channel (PSSCH) related to the PSCCH,
wherein sidelink control information (SCI) is received through the PSCCH or the PSSCH related to the PSCCH, and
wherein the SCI includes information representing whether the PSSCH is a last PSSCH transmission;
determining a physical sidelink feedback channel (PSFCH) resource based on an index of a slot and an index of a sub-channel related to the PSSCH;
transmitting, to the second device, sidelink (SL) hybrid automatic repeat request (HARQ) acknowledgment (ACK) information through the PSFCH resource; and
entering a sleep state, based on the SCI including information representing that the PSSCH is the last PSSCH transmission and the SL HARQ ACK information being transmitted through the PSFCH resource by the first device.
