Claim 22:
23. An apparatus for wireless communication at a user equipment (UE), comprising:
at least one processor; and
at least one memory coupled with the at least one processor, with instructions stored in the at least one memory, the instructions being executable by the at least one processor to cause the apparatus to:
receive radio resource control signaling indicating a number of protocol data units that the UE is configured to store in a buffer at the UE for decoding lost protocol data units;
identify that the UE failed to receive or decode a protocol data unit scheduled to be transmitted by a network entity in a broadcast or unicast transmission;
transmit, to the network entity, a status protocol data unit indicating that the UE failed to receive or decode the protocol data unit;
receive, from the network entity and responsive to the status protocol data unit, a repair protocol data unit comprising redundant bits of a plurality of protocol data units including the protocol data unit that the UE failed to receive or decode, the repair protocol data unit indicating a range of sequence numbers of the plurality of protocol data units for which redundant bits are included in the repair protocol data unit; and
combining at least one correctly decoded protocol data unit stored in the buffer with the redundant bits of the protocol data unit in an attempt to decode at least the protocol data unit that the UE failed to receive or decode.
