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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for transmitting control information in a wireless  communication system","description":"The present invention relates to a wireless communication system.
