1. A method for performing, by a first device, wireless communication, the method comprising:
obtaining a sidelink (SL) discontinuous reception (DRX) configuration including an SL DRX hybrid automatic repeat request (HARQ) round trip time (RTT) timer value for HARQ disabled sidelink transmission;
receiving SCI for scheduling of a physical sidelink shared channel (PSSCH); and
starting an SL DRX HARQ RTT timer, based on a physical sidelink feedback channel (PSFCH) resource being configured to an SL grant related to the SCI and a HARQ feedback being disabled,
wherein the SL DRX HARQ RTT timer is started in a slot following an end of a transmission through the PSSCH, based on resources for one or more retransmission opportunities being scheduled in the SCI, and
wherein the SL DRX HARQ RTT timer is started in a slot following an end of the PSFCH resource and runs as long as the SL DRX HARQ RTT timer value, based on resources for one or more retransmission opportunities being not scheduled in the SCI.
