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.
