Abstract

The present invention relates to a wireless communication system. More specifically, the present invention relates to a method for transmitting control signal via a PUCCH in a wireless communication system, and to an apparatus for the method, wherein the method comprises the following steps: joint-coding a plurality of pieces of control information to obtain a single codeword; obtaining a first modulation symbol sequence from the single codeword; obtaining, from the first modulation symbol sequence, a plurality of second modulation symbol sequences corresponding to each slot in the PUCCH; cyclically shifting the plurality of second modulation symbol sequences in a time domain to obtain a plurality of third modulation symbol sequences; performing a discrete Fourier transform (DFT) precoding process on the plurality of third modulation symbol sequences to obtain a plurality of complex symbol sequences in a frequency domain; and transmitting the plurality of complex symbol sequences via the PUCCH.
