Claim:
A method for transmitting an uplink control information in a terminal, the method comprising: multiplying symbols including the control information by a frequency domain orthogonal sequence and a time domain orthogonal sequence (C 0 , C 1 , C 2 , C 3 ) with a length of 4; mapping the symbols multiplied by the frequency domain orthogonal sequence and the time domain orthogonal sequence to an uplink control channel (PUCCH) comprising seven OFDM symbols; and transmitting the uplink control channel to a base-station, wherein a first two elements (C 0 , C 1 ) of the time domain orthogonal sequence are orthogonal to a first two elements (C 0 , C 1 ) of a time domain orthogonal sequence of another terminal using the same frequency domain orthogonal sequence with the terminal, and a last two elements (C 2 , C 3 ) of the time domain orthogonal sequence are orthogonal to a last two elements (C 2 , C 3 ) of the time domain orthogonal sequence of the another terminal.
