Multicast transmission feedback and buffer processing

A method for wireless communications at a user equipment (UE), comprising:

• receiving broadcast signaling having a periodicity above a first threshold, a transport block size below a second threshold, or both;
• receiving a multicast downlink transmission that is configured without feedback processing;
• and
• processing the multicast downlink transmission and the broadcast signaling during a same time period based at least in part on a remainder of a baseband processing budget for broadcast signaling processing.

An apparatus for wireless communications 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 first control signaling indicating a first radio network temporary identifier and a first feedback process identifier, wherein the first radio network temporary identifier indicates scheduling of a unicast downlink transmission;
• receive second control signaling indicating a second radio network temporary identifier and a second feedback process identifier, wherein the second radio network temporary identifier indicates scheduling of a multicast downlink transmission;
• and
• manage a hybrid automatic repeat request process at the UE associated with the unicast downlink transmission and the multicast downlink transmission based at least in part on the first radio network temporary identifier, the first feedback process identifier, the second radio network temporary identifier, and the second feedback process identifier.
