Method and device for transmitting uplink control channel in wireless cellular communication system

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.
