Abstract: Provided are a method for performing wireless communication by a first device, and an apparatus for supporting same. The method may comprise: obtaining a sidelink (SL) discontinuous reception (DRX) configuration including information related to a timer for an active time and information related to a hybrid automatic repeat request (HARQ) round trip time (RTT) timer; starting the timer for the active time; receiving, from a second device through a physical sidelink control channel (PSCCH) based on a first SL resource, a first sidelink control information (SCI) for scheduling of a physical sidelink shared channel (PSSCH) and a second SCI; and receiving, from the second device through the PSSCH based on the first SL resource, the second SCI and data. Herein, based on resource allocation information for a second SL resource being included in the first SCI, the first device may not monitor retransmission of the data from the second device in a time domain between the first SL resource and the second SL resource, and based on the resource allocation information for the second SL resource not being included in the first SCI, the HARQ RTT timer included in the SL DRX configuration may be started by the first device.
