A method for wireless communications at a user equipment, UE, the method comprising: receiving a first downlink control information transmission from a base station that provides a first set of group-based acknowledgment feedback parameters associated with a first downlink transmission, wherein the first set of group-based acknowledgment feedback parameters includes a first new acknowledgment feedback indicator and a first feedback timing that indicates a first uplink transmission that is to include a first group-based acknowledgment feedback; receiving a second downlink control information transmission from the base station that provides a second set of group-based acknowledgment feedback parameters associated with a second downlink transmission, wherein the second set of group-based acknowledgment feedback parameters includes a second new acknowledgment feedback indicator that is different than the first new acknowledgment feedback indicator, and a second feedback timing that indicates the first uplink transmission that is to include the first group-based acknowledgment feedback, and the first new acknowledgment feedback indicator and the second new acknowledgment feedback indicator indicate that a downlink assignment indicator field is reset; and determining , based at least in part on which of the first new acknowledgment feedback indicator or the second new acknowledgment feedback indicator is received latest in time, the first group-based acknowledgment feedback which is associated with the first downlink control information transmission and the second downlink control information transmission. receiving a first downlink control information transmission from a base station that provides a first set of group-based acknowledgment feedback parameters associated with a first downlink transmission, wherein the first set of group-based acknowledgment feedback parameters includes a first new acknowledgment feedback indicator and a first feedback timing that indicates a first uplink transmission that is to include a first group-based acknowledgment feedback; receiving a second downlink control information transmission from the base station that provides a second set of group-based acknowledgment feedback parameters associated with a second downlink transmission, wherein the second set of group-based acknowledgment feedback parameters includes a second new acknowledgment feedback indicator that is different than the first new acknowledgment feedback indicator, and a second feedback timing that indicates the first uplink transmission that is to include the first group-based acknowledgment feedback, and the first new acknowledgment feedback indicator and the second new acknowledgment feedback indicator indicate that a downlink assignment indicator field is reset; and the second set of group-based acknowledgment feedback parameters includes a second new acknowledgment feedback indicator that is different than the first new acknowledgment feedback indicator, and a second feedback timing that indicates the first uplink transmission that is to include the first group-based acknowledgment feedback, and the first new acknowledgment feedback indicator and the second new acknowledgment feedback indicator indicate that a downlink assignment indicator field is reset; and determining , based at least in part on which of the first new acknowledgment feedback indicator or the second new acknowledgment feedback indicator is received latest in time, the first group-based acknowledgment feedback which is associated with the first downlink control information transmission and the second downlink control information transmission. <EOS>
