Classification: CPC H | IPC H

Claim 8:
9. A method performed by a base station for receiving an uplink signal in a wireless communication system, the method comprising:
transmitting, to a terminal, a higher layer signal comprising first information indicating an orthogonal cover code (OCC) index for a long physical uplink control channel (PUCCH) format; and
receiving, from the terminal on a PUCCH based on the long PUCCH format, uplink control information and a demodulation reference signal (DMRS) for the uplink control information based on N symbols,
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.
