1. A method performed by a terminal in a communication system, the method comprising:
receiving, from a base station, higher layer signaling configuring two physical downlink shared channel (PDSCH) groups;
receiving, from the base station, first downlink control information (DCI) scheduling a first PDSCH corresponding to a first PDSCH group of number n, wherein the first DCI includes a first new feedback indicator (NFI) for the first PDSCH group, where n corresponds to 0 or 1;
receiving, from the base station, second DCI scheduling a second PDSCH corresponding to a second PDSCH group of number (n+1) mod 2, wherein the second DCI includes a second NFI for the first PDSCH group and at least one of a first downlink assignment index (DAI) or a second DAI for the second PDSCH group, and a third DAI for the first PDSCH group, and group codebook indication information; and
in case that the group codebook indication information indicates a feedback of hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook of both the first PDSCH group and the second PDSCH group:
generating a HARQ-ACK codebook for the first PDSCH group and a HARQ-ACK codebook for the second PDSCH group; and
transmitting, to the base station, both of the HARQ-ACK codebook for the first PDSCH group and the HARQ-ACK codebook for the second PDSCH group,
wherein the third DAI in the second DCI corresponds to both a first HARQ-ACK sub-codebook associated with a transport block (TB)-ACK and a second HARQ-ACK sub-codebook associated with a code block group (CBG)-ACK for the first PDSCH group.
