1. An apparatus for wireless communications at a user equipment (UE), comprising:
one or more processors;
one or more memories coupled with the one or more processors; and
one or more processor-readable instructions stored in the one or more memories and executable by the one or more processors, individually or collectively, to cause the apparatus to:
receive, from a network device via a first downlink channel, a message indicating an acknowledgment feedback configuration for multicast messages;
receive, from the network device via the first downlink channel, a downlink control information message that is associated with scheduling the multicast messages, the downlink control information message comprising an indication that configures whether the UE is enabled to provide acknowledgment feedback for the multicast messages in accordance with the acknowledgment feedback configuration;
receive, from the network device via a second downlink channel, a multicast data message; and
transmit, to the network device via an uplink channel, an acknowledgment feedback message in accordance with the acknowledgment feedback configuration, the acknowledgment feedback message being transmitted in response to the received multicast data message based at least in part on the received downlink control information message comprising the indication that configures whether the UE is enabled to provide the acknowledgment feedback for the multicast messages.
