1. A method for performing sidelink (SL) communication by a first apparatus, the method including:
receiving information related to a plurality of resources from a second apparatus;
receiving a physical sidelink share channel (PSSCH) and a physical sidelink control channel (PSCCH) from the second apparatus on a first resource among the plurality of resources;
determining resources after the first resource among the plurality of resources as a candidate resource for SL transmission by the first apparatus based on a successful decoding of a transport block received through the PSSCH; and
performing SL communication based on the candidate resource for the SL transmission by the first apparatus,
wherein the resources after the first resource determined as the candidate resource are resources after a processing time required for the first apparatus to transmit hybrid automatic repeat request (HARQ) feedback information through a physical sidelink feedback channel (PSFCH) related to the PSSCH to the second apparatus has elapsed or after processing of the HARQ feedback information is completed by the second apparatus after the second apparatus receives the HARQ feedback information.
