1. A method for performing, by a first device, wireless communication, the method comprising:
receiving, from a base station, a first sidelink grant;
obtaining a medium access control (MAC) packet data unit (PDU) for the first sidelink grant, wherein a logical channel configured with hybrid automatic repeat request (HARQ) feedback disabled and a logical channel configured with HARQ feedback enabled cannot be multiplexed into the MAC PDU; and
transmitting, to the base station, negative acknowledgement on a physical uplink control channel (PUCCH) resource, based on (i) the PUCCH resource configured for the first device, (ii) HARQ feedback disabled for the MAC PDU, and (iii) no sidelink grant available for next retransmission of the MAC PDU.
