1. A method for wireless communications at a user equipment (UE), comprising:
receiving 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;
receiving 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, wherein a combined data rate for the unicast downlink transmission and the multicast downlink transmission is less than a component carrier data rate; and
processing the multicast downlink transmission or the unicast downlink transmission as a new data transmission irrespective of whether a new data indicator value is toggled in the first control signaling or the second control signaling, the processing 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.
