Claim 4:
5. A method performed by a base station in a communication system, the method comprising:
transmitting, to a terminal, a plurality of semi persistent scheduling (SPS) physical downlink shared channel (PDSCH) configurations, wherein the plurality of SPS PDSCH configurations respectively including SPS configuration indexes;
transmitting, to the terminal, a plurality of downlink control information (DCI) formats indicating activations of SPS PDSCHs respectively corresponding to the SPS configuration indexes;
transmitting, to the terminal, a single DCI format indicating a plurality of SPS PDSCH releases; and
receiving, from the terminal, a hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook including HARQ-ACK information corresponding to the plurality of SPS PDSCH releases,
wherein a location in the HARQ-ACK codebook for the HARQ-ACK information is same as for a corresponding SPS PDSCH reception with a lowest SPS configuration index among the plurality of SPS PDSCH releases, and
wherein the plurality of SPS PDSCH releases are indicated based on a value of a HARQ process number field in the single DCI format.
