1. A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
receiving first downlink control information (DCI), wherein the first DCI includes a single physical downlink shared channel (PDSCH) group index value and a value of a number of requested PDSCH groups, and wherein a first PDSCH group index of a first PDSCH group of two PDSCH groups is set to the single PDSCH group index value and a second PDSCH group index of a second PDSCH group of the two PDSCH groups that is different from the first PDSCH group index is determined based on the single PDSCH group index value;
receiving PDSCHs, wherein each of the PDSCHs belongs to one of the two PDSCH groups;
receiving second DCI for scheduling a physical uplink shared channel (PUSCH), wherein the second DCI includes a single downlink assignment index (DAI); and
transmitting hybrid automatic repeat request (HARQ)-acknowledgement (ACK) information,
wherein based on i) the HARQ-ACK information including ACK/negative ACK (NACK) information for both the first PDSCH group and the second PDSCH group and ii) the first PDSCH group index is 0, the single DAI is used to generate a HARQ-ACK codebook for the first PDSCH group.
