CPC H04L 1/1621 (2013.01) [H04B 7/0456 (2013.01); H04W 72/1273 (2013.01); H04W 72/23 (2023.01)] | 14 Claims |
1. A method for wireless communication at a user equipment (UE), comprising:
receiving, from a base station, configuration information for group-based acknowledgment feedback for at least a first group of downlink transmissions to the UE and a second group of downlink transmissions to the UE, wherein one or more of the first group of downlink transmissions or the second group of downlink transmissions are configured for acknowledgment feedback at a code-block-group level or a transport-block level;
receiving a downlink control information transmission from the base station that schedules a first uplink transmission in which acknowledgment feedback for one or more of the first group of downlink transmissions or the second group of downlink transmissions is to be multiplexed with uplink data in the first uplink transmission, wherein:
group-based acknowledgment feedback is to be provided for one or more of the first group of downlink transmissions or the second group of downlink transmissions, in the first uplink transmission;
receiving the downlink control information transmission comprises receiving uplink total downlink assignment indicator fields for each of the first group of downlink transmissions and the second group of downlink transmissions;
the acknowledgment feedback is determined based at least in part on the uplink total downlink assignment indicator fields; and
the uplink total downlink assignment indicator fields for each of the first group of downlink transmissions and the second group of downlink transmissions include one or more of a first downlink assignment indicator field associated with a first codebook for transport-block level acknowledgment feedback of the first group of downlink transmissions or a second downlink assignment indicator field associated with a second codebook for code-block-group level acknowledgment feedback of the first group of downlink transmissions;
determining, based at least in part on the configuration information for the group-based acknowledgment feedback and the downlink control information transmission, acknowledgment feedback associated with at least one of the first group of downlink transmissions or the second group of downlink transmissions; and
transmitting the acknowledgment feedback to the base station in the first uplink transmission.
