The present invention relates to a wireless communication system. More specifically, the present invention relates to a method for transmitting control information through a PUCCH in a wireless communication system and an apparatus thereof, comprising the steps of: dividing a modulation symbol set for the control information so that the divided sets are equivalent to two slots on the PUCCH; spreading the modulation symbol sets divided to be equivalent to first slots, by using a first code, so that the spread sets are equivalent to a plurality of SC-FDMA symbols; DFT-converting, in an SC-FDMA symbol unit, the modulation symbol sets spread to be equivalent to the plurality of SC-FDMA symbols on the first slots; spreading the modulation symbol sets divided to be equivalent to second slots, by using a second code, so that the divided sets are equivalent to a plurality of SC-FDMA symbols; DFT-converting, in an SC-FDMA symbol unit, the modulation symbol sets spread to be equivalent to the plurality of SC-FDMA symbols on the second slots; and transmitting DFT-converted signals through the corresponding SC-FDMA symbols on the first and second slots, wherein the length of the second code is varied according to the number of the SC-FDMA symbols for PUCCH transmission. |
