receiving first Downlink Control Information (DCI) scheduling a first Physical Downlink Shared Channel (PDSCH);
determining an index of a first PDSCH group is zero in response to the first DCI not including a first indicator that indicates the index of the first PDSCH group, wherein the first PDSCH group includes at least the first PDSCH;
determining whether new Hybrid Automatic Repeat reQuest Acknowledgement (HARQ-ACK) feedback is requested for the first PDSCH group; and
transmitting a first HARQ-ACK codebook for the first PDSCH group, wherein the first HARQ-ACK codebook includes HARQ-ACK feedback for each PDSCH of the first PDSCH group.
