1. A method performed by a base station in a wireless communication system, the method comprising:
allocating a first physical uplink control channel (PUCCH) resource of a format 3 to a first terminal;
identifying a position of a first demodulation reference signal (DMRS) for the first PUCCH resource;
allocating a second PUCCH resource of a format 0 to a second terminal, the second PUCCH resource is allocated to the position of the first DMRS;
transmitting information on allocation of the first PUCCH resource and the second PUCCH resource; and
receiving uplink control information through the first PUCCH resource and the second PUCCH resource,
wherein the first DMRS and the second PUCCH resource are multiplexed in the position of the first DMRS, and
wherein a residual cyclic shift of the format 3 is determined for the second terminal.
