Multiple feedback control for group common-physical downlink shared channel (GC-PDSCH) in multimedia broadcast multicast service (MBMS)

A network entity comprising:

• at least one processor;
• and
• a memory coupled with the at least one processor and storing processor-readable code that, when executed by the at least one processor, is configured to:
• transmit, to a plurality of user equipments (UEs), a plurality of multicast transmission grants that respectively schedule a plurality of multicast transmissions, including a first multicast transmission grant that schedules a first multicast transmission, each of the multicast transmission grants including a respective common feedback timing indicator (K1) and a respective plurality of physical uplink control channel (PUCCH) resource indicators (PRIs) for acknowledgement/negative-acknowledgement (ACK/NACK) feedback associated with the respective multicast transmission associated with the multicast transmission grant, the common K1 being shared by the plurality of UEs, each PRI of the plurality of PRIs being associated with a respective UE of the plurality of UEs;
• transmit, to the plurality of UEs, the first multicast transmission in accordance with the first multicast transmission grant;
• and
• receive, from a first UE of the plurality of UEs, on a first feedback resource associated with the common K1 and the respective PRI associated with the first UE in the first multicast transmission grant, a first feedback codebook including ACK/NACK feedback associated with the first multicast transmission.

A method for wireless communication performed by a user equipment (UE), the method comprising:

• receiving, from a network entity, a plurality of multicast transmission grants, addressed to a plurality of UEs including the UE, that respectively schedule a plurality of multicast transmissions, including a first multicast transmission grant that schedules a first multicast transmission, each of the multicast transmission grants including a respective common feedback timing indicator (K1) and a respective plurality of physical uplink control channel (PUCCH) resource indicators (PRIs) for acknowledgement/negative-acknowledgement (ACK/NACK) feedback associated with the respective multicast transmission associated with the multicast transmission grant, the common K1 being shared by the plurality of UEs, each PRI of the plurality of PRIs being associated with a respective UE of the plurality of UEs;
• receiving, from the network entity, the first multicast transmission in accordance with the first multicast transmission grant;
• and
• transmitting, to the network entity on a first feedback resource associated with the common K1 and the respective PRI associated with the UE in the first multicast transmission grant, a first feedback codebook carrying ACK/NACK feedback associated with the first multicast transmission to the base station.
