1. A user equipment (UE) for wireless communication, comprising:
at least one memory; and
at least one processor coupled with the at least one memory and configured to cause the UE to:
receive a first plurality of downlink control information (DCI) formats for scheduling a second plurality of physical downlink shared channel (PDSCH) transmissions on at least one serving cell of the UE, wherein each of the first plurality of DCI formats schedules one or more PDSCH transmissions of the second plurality of PDSCH transmissions and includes an indicator for the UE to generate a hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook for the second plurality of PDSCH transmissions, and wherein the indicator indicates a respective quantity of scheduled PDSCH transmissions up to a current serving cell and a current physical downlink control channel (PDCCH) monitoring occasion;
receive the second plurality of PDSCH transmissions based on the first plurality of DCI formats;
generate the HARQ-ACK codebook based on the indicators in the first plurality of DCI formats; and
transmit the HARQ-ACK codebook.
