1. A method for performing wireless communication by a first device, the method comprising:
obtaining a medium access control (MAC) protocol data unit (PDU) for which hybrid automatic repeat request (HARQ) feedback is enabled;
performing an (N−1)-th transmission of the MAC PDU to a second device;
determining that the (N−1)-th transmission of the MAC PDU has failed;
transmitting, to the second device, control information for disabling the HARQ feedback for an N-th transmission of the MAC PDU for which the HARQ feedback is enabled, based on a failure of the (N−1)-th transmission of the MAC PDU; and
performing the N-th transmission of the MAC PDU to the second device,
wherein N is a maximum number of transmissions related to the MAC PDU and is a positive integer.
