1. A method for wireless communication performed by a user equipment (UE), comprising:
receiving, from a network device on a granting group common (GC)-physical downlink control channel (PDCCH), a multimedia broadcast multicast service (MBMS) downlink grant that schedules an MBMS transmission for a group of UEs that includes the UE;
receiving, from a network device, a search space parameter that configures a search space associated with a triggering GC-PDCCH, a length associated with the triggering GC-PDCCH, a radio network temporary identifier (RNTI) associated with the triggering GC-PDCCH, and one or more feedback bit fields associated with the triggering GC-PDCCH;
receiving, from a network device, on the triggering GC-PDCCH in association with monitoring the search space, the one or more feedback bit fields indicating respective feedback resources for each UE of the group of UEs;
and
transmitting, to a network device via the respective feedback resources for the UE, a feedback report associated with the MBMS transmission.
