1. A method for wireless communication at a user equipment (UE), comprising:
receiving a configuration message identifying a set of resources available for use by a plurality of UEs for transmission of feedback indications of multi-cast or broadcast transmission to the plurality of UEs, the set of resources comprising at least spatial resources divided into a plurality of subsets of resources, each subset of resources being associated with a corresponding channel metric for each UE of the plurality of UEs receiving the multi-cast or broadcast transmission;
receiving control information indicating one or more resources to select from within each subset of resources in the set of resources, the one or more resources corresponding to a UE-specific feature;
determining that a feedback indication is to be provided in response to the multi-cast or broadcast transmission;
selecting, based at least in part on a channel metric of the UE, a first subset of resources of the plurality of subsets of resources;
selecting the one or more resources within the first subset of resources in accordance with the UE-specific feature and the control information; and
transmitting the feedback indication in a feedback message for the multi-cast or broadcast transmission using at least the one or more resources within the first subset of resources.
