1. A method performed by a terminal for transmitting an uplink signal in a wireless communication system, the method comprising:
receiving, from a base station, a higher layer signal comprising first information indicating an orthogonal cover code (OCC) index for a long physical uplink control channel (PUCCH) format;
generating uplink control information to be transmitted on a PUCCH based on the long PUCCH format;
determining N symbols in which the uplink control information is to be transmitted; and
transmitting, to the base station on the PUCCH based on the long PUCCH format, the uplink control information and a demodulation reference signal (DMRS),
wherein:
a first spreading code for a first uplink control information symbol in a first hop is determined based on the first information and a first symbol duration of the first uplink control information symbol,
a second spreading code for a first DMRS symbol in the first hop is determined based on the first information and a second symbol duration of the first DMRS symbol,
a third spreading code for a second uplink control information symbol in a second hop is determined based on the first information and a third symbol duration of the second uplink control information symbol, and
a fourth spreading code for a second DMRS symbol in the second hop is determined based on the first information and a fourth symbol duration of the second DMRS symbol.
