1. A method for performing wireless communication by a first device, the method comprising:
receiving, from a base station, information related to a sidelink (SL) grant and information related to a physical uplink control channel (PUCCH) resource;
obtaining a medium access control (MAC) packet data unit (PDU);
generating hybrid automatic repeat request (HARQ) feedback information related to the MAC PDU; and
transmitting, to the base station, the HARQ feedback information based on the PUCCH resource,
wherein, based on that the first device does not transmit the MAC PDU, due to prioritization, the HARQ feedback information is generated as a negative acknowledgment (NACK).
