Classification: CPC H | IPC H

Claim 4:
5. A terminal for transmitting an uplink signal in a wireless communication system, the terminal comprising:
a transceiver configured to transmit and receive signals; and
a controller configured to:
receive, 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,
generate uplink control information to be transmitted on a PUCCH based on the long PUCCH format,
determine N symbols in which the uplink control information is to be transmitted, and
transmit, 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.
