Abstract: Proposed are a method by which a first device performs wireless communication and an apparatus supporting same. For example, the first device may acquire an SL DRX configuration including information related to an active time of a second device. For example, the first device may monitor SL HARQ feedback information for the MAC PDU on a PSFCH resource determined on the basis of an index of a sub-channel and an index of a slot, which are related to the PSSCH. For example, the first device may transmit, on the UL resource to the base station, information for allowing an additional SL resource not to be allocated from the base station, on the basis that the number of times the SL HARQ feedback information is not received reaches a threshold value.
