1. A method for performing wireless communication by a first device, the method comprising:
receiving, from a base station, information related to a configured grant (CG) resource, wherein the CG resource includes at least one of a first resource related to CG type 1 or a second resource related to CG type 2;
receiving, from the base station, information related to a dynamic grant (DG) resource; and
performing a first sidelink (SL) transmission based on one of the CG resource or the DG resource,
wherein the CG resource or the DG resource overlaps in a time domain,
wherein, based on the first SL transmission that is initial transmission, the first SL transmission is performed based on a resource related to the first SL transmission among the CG resource or the DG resource, and
wherein, based on second SL transmission that is retransmission, the second SL transmission is not performed based on a resource related to the second SL transmission among the CG resource or the DG resource.
