Abstract
Wireless communications systems and methods related to acknowledgement/negative-acknowledgement (ACK/NACK) feedback operations for multicast communications are provided. A first user equipment (UE) receives, from a base station (BS), a multicast feedback configuration indicating a first resource configuration for a negative-acknowledgement (NACK) feedback mode; and a second resource configuration for an acknowledgement/negative-acknowledgement (ACK/NACK) feedback mode. The first UE receives, from the BS, a first multicast communication. The first UE transmits, to the BS, a NACK feedback for the first multicast communication based on the first resource configuration. The first UE receives, from the BS, a second multicast communication. The first UE transmits, to the BS, an ACK feedback or a NACK feedback for the second multicast communication based on the second resource configuration.
