1. A method for wireless communications at a user equipment (UE), comprising:
receiving an indication of uplink control channel resources for reporting acknowledgement feedback by the UE for multicast communications, the uplink control channel resources to be shared by UEs associated with the multicast communications;
measuring one or more multicast channels or one or more signals monitored by the UE to determine a set of channel state information for UE receipt of the multicast communications;
selecting one of the uplink control channel resources based at least in part on an association between the set of channel state information and the one of the uplink control channel resources, and based at least in part on the UE being associated with a first group of UEs;
determining that a condition of the one or more multicast channels has changed by a threshold amount, wherein the UE becomes associated with a second group of UEs based at least in part on the condition changing by the threshold amount;
selecting a different one of the uplink control channel resources based at least in part on the UE being associated with the second group of UEs; and
transmitting an acknowledgement feedback message over the one of the uplink control channel resources.
