1. A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
receiving, from a base station (BS), configuration information regarding a hybrid automatic repeat and request-acknowledgement (HARQ-ACK) retransmission via higher layer signaling;
transmitting, to the BS, a first HARQ-ACK codebook, on a first slot;
receiving, from the BS, a downlink control information (DCI);
according to the configuration information, identifying an offset for the HARQ-ACK retransmission based on values of a modulation and coding scheme (MCS) field included in the DCI, wherein the offset indicates an interval between a slot carrying the DCI and the first slot; and
retransmitting the first HARQ-ACK codebook, which is transmitted in the first slot, on a second slot.
