1. A method for performing, by a first device, wireless communication, the method comprising:
receiving, from a base station, information related to a physical uplink control channel (PUCCH) transmission occasion for sidelink (SL);
receiving, from the base station, an SL grant related to the PUCCH transmission occasion, including a retransmission resource for a transmission to a second device;
generating a medium access control (MAC) protocol data unit (PDU) to be retransmitted based on the SL grant;
obtaining SL discontinuous reception (DRX) configuration of the second device;
determining that the retransmission resource is not in an active time of the SL DRX configuration; and
transmitting, to the base station, negative acknowledge (NACK) through the PUCCH transmission occasion.
