    Abstract: A method for transmitting, by a user equipment (UE), an aperiodic sounding reference signal (SRS) in a wireless communication system; and the UE are discussed. The method includes receiving a downlink control information (DCI) format, which schedules a physical uplink shared channel (PUSCH) and includes an SRS request for triggering transmission of an aperiodic SRS, from a base station (BS); detecting the SRS request; and transmitting, when the UE is not configured with a carrier indicator field (CIF), the aperiodic SRS to the BS on a first uplink (UL) component carrier (CC) in which the PUSCH is scheduled, or, when the UE is configured with the CIF, the aperiodic SRS to the BS on a second UL CC in which the PUSCH is scheduled with a value of the CIF.

    Abstract: The present invention relates to a method for generating an uplink reference signal in a system supporting plural uplink-access transmission modes. The method comprises: a step for transmitting the reference signal configuration information about the configuration of a reference signal from a base station to a user device through an uplink grant PDCCH (Physical Downlink Control Channel), and a step for receiving from the user device a sub-frame including the reference signal that is generated based on the reference signal configuration information. The reference signal configuration information is prepared for plural uplink access transmission modes and includes a cyclic shift value for the sequence of the reference signal. The reference signal is supposed to be transmitted to an uplink, and the user device is set up to be operated in the uplink-access transmission mode that corresponding to the reference signal configuration information.

    Abstract: The present invention relates to a method for transmitting, by a base station, a downlink signal using a plurality of transmission antennas comprises the steps of: applying a precoding matrix indicated by the PMI, received from a terminal, in a codebook to a plurality of layers, and transmitting the precoded signal to the terminal through a plurality of transmission antennas. Among precoding matrices included in the codebook, a precoding matrix for even number transmission layers can be a 2×2 matrix containing four matrices (W1s), the matrix (W1) having rows of a number of transmission antennas and columns of half the number of transmission layers, the first and second columns of the first row in the 2×2 matrix being multiplied by 1, the first column of the second row being multiplied by coefficient “a” of a phase, and the first column of the second row being multiplied by “−a”.
