Abstract: Proposed are a method by which a first device performs wireless communication, and an apparatus supporting same. For example, the first device may obtain a DRX configuration including information related to a HARQ RTT timer. For example, the first device may obtain information related to a sidelink (SL) resource pool. For example, the first device may start the HARQ RTT timer. For example, the HARQ RTT timer may be a minimum duration before an SL retransmission grant is expected by the first device. For example, based on (i) a physical uplink control channel (PUCCH) configuration not being configured, and (ii) a physical sidelink feedback channel (PSFCH) resource not being configured in the SL resource pool, a value of the HARQ RTT timer may be 0.
