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.

Abstract: A method for a base station to transmit a channel-state-information reference signal for up to 8 antenna ports includes mapping, in accordance with a predetermined pattern, the channel-state-information reference signal for up to 8 antenna ports onto a data region of a downlink subframe having an extended cyclic prefix (CP) structure, and transmitting the downlink subframe onto which the channel-state-information reference signal for up to 8 antenna ports has been mapped; and, in the predetermined pattern, the channel-state-information reference signal for up to 8 antenna ports in mapped onto 2 OFDM symbols on the data region of the downlink subframe, with a definition for mapping onto at least one of 4 subcarrier wave positions in each of the 2 OFDM symbols, and the 4 subcarrier wave positions defined in the predetermined pattern can be disposed at 3 subcarrier wave intervals.

Abstract: The present system relates to a method for transmitting control information in a wireless communications system that supports coordinated multi-point (CoMP) including N (N>1) transmission points. The method comprises: generating control information for downlink transmission of the N transmission points; and transmitting the generated control information to a user device, wherein the control information contains a control information region for transmission of intrinsic control information on a reference transmission point among the N transmission points, and N?1 control information regions for transmission of intrinsic control information on the N?1 transmission points.

Abstract: A method for transmitting a band bitmap in a wireless communication system is provided. The method includes selecting at least one selection band from a plurality of bands, the plurality of bands being distributed throughout a whole frequency band, grouping the plurality of bands into a plurality of band groups, setting a primary bitmap for each band group according to whether the selection band is included in each band group and setting a secondary bitmap for bands in each band group, and transmitting the primary bitmap and the secondary bitmap. Radio resources used to transmit a band bitmap can be reduced by decreasing the number of bits of the band bitmap.

Abstract: A method of transmitting a control signal in wireless communication system includes generating a multiplexed control signal by multiplexing a first control signal and a second control signal, and transmitting the multiplexed control signal on a control channel. Overhead due to control signaling can be reduced by transmitting or receiving a multiplexed control signal through one channel.
