Abstract: Methods and apparatuses are provided in a wireless communication system. Configuration information regarding a hybrid automatic repeat and request-acknowledgement (HARQ-ACK) retransmission is received from a base station (BS) via higher layer signaling. Downlink control information (DCI) is received from the BS. An offset for the HARQ-ACK retransmission is identified as a value of a modulation and coding scheme (MCS) field included in the DCI, based on the configuration information. The HARQ-ACK retransmission is performed on a slot identified based on the offset.
