    • The present invention relates to a wireless communication system, and more particularly, to a method and apparatus for transmitting signals using codebooks in a wireless communication system that supports multiple antennas. A method in which a base station transmits downlink signals according to one embodiment of the present invention comprises the following steps: receiving a first precoding matrix indicator (PMI) and a second precoding matrix indicator from a terminal; determining a first matrix (W1) from a first codebook including precoding matrixes indicated by the first PMI, determining a second matrix (W2) from a second codebook, including precoding matrices indicated by the second PMI, and determining a precoding matrix (W) based on the first matrix (W1) and second matrix (W2); performing precoding on one or more layers, to which the downlink signals are mapped, using the determined precoding matrix (W); and transmitting the precoded signals to the terminal. Each of the precoding matrices included in the first codebook is a block diagonal matrix, and one block has, as compared to the other block, a form multiplied by a predetermined phase value.

    • The present invention relates to a wireless communication system. More particularly, the present invention relates to a method for transmitting control information in a wireless communication system and to an apparatus for the method, wherein the method comprises a step of receiving a plurality of scheduling information for transmission using a plurality of physical uplink shared channels (PUSCHs), and a step of transmitting uplink control information (UCI) through one PUSCH among the plurality of PUSCHs, if the transmission using the plurality of PUSCHs is present in the subframe which requires a UCI transmission. If a PUSCH transmission is present on a primary resource in the subframe, the UCI is transmitted through the PUSCH of the primary resource. If a PUSCH transmission is not present on the primary resource in the subframe, the UCI is transmitted through the PUSCH of the secondary resource having the smallest index among a plurality of secondary resources on which PUSCH transmissions are present.
    • 无线通信系统技术领域本发明涉及一种无线通信系统。 更具体地说,本发明涉及一种用于在无线通信系统中发送控制信息的方法和该方法的装置,其中该方法包括以下步骤:使用多个物理上行链路共享信道接收用于发送的多个调度信息 (PUSCH)的发送,以及在需要UCI发送的子帧中存在使用多个PUSCH的发送的情况下,在多个PUSCH中通过一个PUSCH发送上行链路控制信息(UCI)的步骤。 如果在子帧中的主资源上存在PUSCH传输,则通过主资源的PUSCH发送UCI。 如果子帧中的主资源不存在PUSCH传输,则通过存在PUSCH传输的多个辅助资源中具有最小索引的辅助资源的PUSCH来发送UCI。
