Abstract:
Methods, systems, and devices for wireless communications are described. A base station may transmit a downlink control information (DCI) message to one or more user equipments (UEs) scheduling a multicast data message in a multicast downlink shared channel, the DCI message indicating a feedback process identifier (ID) for the multicast data message. The base station may transmit an additional DCI message to a UE scheduling a retransmission of the multicast data message in a unicast downlink shared channel and indicating a feedback process ID for the retransmission of the multicast data message. The feedback process ID for the retransmission may be the same as, or different from, the initial transmission of the multicast data message. The UE may transmit feedback for the multicast data message based on receiving the initial transmission of the multicast data or the retransmission of the multicast data and the feedback process IDs.
