Abstract  Abstract

The present invention relates to a wireless communication system. More particularly the present invention relates to a method in which a terminal transmits control information in a wireless communication system and to an apparatus for the method wherein the method comprises the following steps: spreading a control information block corresponding to one single carrier frequency division multiplexing (SC-FDMA) symbol such that the spread control information blocks correspond to a plurality of first SC-FDMA symbols; performing a discrete Fourier transform (DFT) precoding process on the spread control information blocks on an SC-FDMA symbol basis; transmitting in the plurality of first SC-FDMA symbols in a subframe the DFT precoded control information blocks; and transmitting in a plurality of second SC-FDMA symbols in the subframe a reference signal sequence wherein an orthogonal code is applied to the plurality of second SC-FDMA symbols in a time domain.
