A method for a HARQ feedback transmission includes receiving a multicast broadcast service (MBS) transport block (TB) from a base station, decoding the MBS TB, and transmitting, to the base station, a HARQ feedback in a form of a negative acknowledgement (NACK)-only report when the UE incorrectly decodes the MBS TB.
