1. A method performed by a terminal in a wireless communication system, the method comprising:
receiving a physical downlink control channel (PDCCH), the PDCCH including downlink control information (DCI) for scheduling one or more physical downlink shared channels (PDSCHs);
receiving the PDSCHs according to the DCI;
transmitting a hybrid automatic repeat request acknowledgement (HARQ-ACK/NACK) codebook for the PDSCHs;
grouping, for a plurality of PDSCHs that are fed back in the HARQ-ACK/NACK codebook, the PDSCHs according to a DCI format of the DCI for scheduling each of the PDSCHs, wherein PDSCHs scheduled by DCI of a given DCI format belong to a given PDSCH group; and
determining the codebook for each PDSCH group.
