A method and apparatus for transmitting uplink control information (UCI) performed by a terminal in a wireless communication system are provided. The method performs channel coding on information bits of UCI to generate encoding information bits, modulates the generated encoding information bits to generate modulation symbol sequences, Block-wise spreading of the modulation symbol sequence into an orthogonal sequence to generate a spreading sequence, and the spreading sequence is transmitted to a base station through an uplink control channel. The information bits of the UCI include a first UCI bit sequence and a second UCI information bit. |
