Multi-user packet for user equipment assisted retransmission

A method for wireless communications performed by a base station (BS), comprising:

• transmitting a multi-user physical (MUP) downlink shared channel (PDSCH) communication (MUPC) comprising a plurality of payloads to a plurality of UEs;
• receiving a negative acknowledgement (NACK) from a first UE of the plurality of UEs in response to the MUPC;
• receiving an acknowledgement (ACK) from a second UE of the plurality of UEs in response to the MUPC;
• and
• transmitting, to the second UE in response to receiving the NACK from the first UE and the ACK from the second UE, a first message requesting the second UE to retransmit at least one payload of the plurality of payloads.

A user equipment (UE) for wireless communication, comprising:

• a memory, and
• at least one processor operatively coupled to the memory, the memory and the at least one processor configured:
• to receive a multi-user physical (MUP) downlink shared channel (PDSCH) communication (MUPC) comprising a plurality of payloads;
• to transmit an acknowledgement (ACK) in response to decoding the MUPC;
• to receive a message requesting retransmission of at least one payload of the plurality of payloads;
• and
• to transmit the at least one payload in response to the message.
