PROBLEM TO BE SOLVED: To provide a method and a device for transmitting control information through PUCCH (physical uplink control channel) in a radio communication system.SOLUTION: The control information transmission method includes: spreading a first modulation symbol sequence in a manner to associate with a plurality of SC-FDMA symbols in a first slot to acquire a plurality of second modulation symbol sequence associated with the plurality of SC-FDMA symbols; performing DFT precoding to the plurality of second modulation symbol sequence to acquire a plurality of complex symbol sequences; and transmitting the plurality of complex symbol sequences through a PUCCH. To the plurality of second modulation symbol sequences, scramble is applied on an SC-FDMA symbol level.SELECTED DRAWING: Figure 29a |
