1. A method for wireless communications at a user equipment (UE), comprising:
receiving, from a network device, configuration information for group-based acknowledgment feedback for one or more of a first downlink transmission group or a second downlink transmission group;
receiving downlink control information from the network device, wherein the downlink control information schedules a first uplink transmission in which acknowledgment feedback for one or more of the first downlink transmission group or the second downlink transmission group is to be multiplexed with uplink data in the first uplink transmission, and wherein the downlink control information provides a first downlink assignment indicator value;
determining, based at least in part on the configuration information for the group-based acknowledgment feedback and the first downlink assignment indicator value, an acknowledgment feedback format for an acknowledgment feedback report associated with the first downlink transmission group, the second downlink transmission group, or both;
formatting the acknowledgment feedback report with an acknowledgment feedback codebook associated with a fixed downlink transmission group associated with the first downlink assignment indicator value; and
transmitting the acknowledgment feedback report to the network device in the first uplink transmission.
