Discontinuous reception operation for new radio multicast communications

An apparatus for wireless communication at a user equipment (UE), comprising:

• a processor,
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• receive, in an active duration of a multicast discontinuous reception cycle, downlink control information indicating resources of a downlink data channel for a multicast message for a plurality of apparatuses, including the apparatus;
• monitor the indicated resources for the multicast message;
• transmit, based at least in part on the monitoring the indicated resources, a feedback message corresponding to the multicast message;
• and
• initiate a multicast feedback timer based at least in part on the monitoring the indicated resources for the multicast message, the multicast feedback timer indicating a time to begin monitoring for a retransmission of the multicast message, the multicast feedback timer different than a unicast feedback timer associated with unicast messages for the UE.
