1. A method of wireless communication at a user equipment (UE), comprising:
receiving a first configuration associated with transmission on a first channel for transmitting hybrid automatic repeat request (HARQ) acknowledgement (ACK) feedback associated with unicast communication, the first configuration including a first value of a parameter;
receiving a second configuration associated with transmission on a second channel for transmitting HARQ ACK feedback for multicast data, the second configuration being separate from the first configuration, the second configuration including a second value of a parameter;
receiving a downlink control information (DCI) message;
receiving, from a network entity, a first data transmission;
detecting that the first data transmission is a multicast data transmission based on a radio network temporary identifier (RNTI) associated with the first data transmission; and
in response to receiving the first data transmission and the detection, transmitting, to the network entity, a first HARQ ACK feedback message for the multicast data transmission on a first resource identified for transmitting multicast acknowledgement feedback, wherein the first resource is identified based at least in part on a number of bits in uplink control information (UCI) and a physical uplink control channel (PUCCH) resource indicator (PRI) associated with the DCI message and application of the second value of the parameter included in the second configuration.
