1. A method performed by a terminal in a wireless communication system, the method comprising:
receiving, from a base station, downlink control information (DCI) for scheduling a physical downlink shared channel (PDSCH), wherein the DCI comprises information associated with a slot for a physical uplink control channel (PUCCH) and information associated with a PUCCH format among at least one PUCCH format;
applying a sequence and an orthogonal sequence to hybrid automatic repeat request acknowledgement (HARQ-ACK) information for the PDSCH; and
transmitting, to the base station in the slot, a demodulation reference signal (DMRS) for the HARQ-ACK information and the HARQ-ACK information applied with the sequence and the orthogonal sequence based on the PUCCH format,
wherein a number of symbols of the PUCCH format comprises variable and even number, and
wherein the DMRS for the HARQ-ACK information is mapped to at least one symbol with even-numbered index including index 0 within the symbols of the PUCCH format and the HARQ-ACK information is mapped to at least one symbol with odd-numbered index within the symbols of the PUCCH format.
