    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”.

    Abstract: A method and a user equipment (UE) for generating a reference signal sequence in a wireless communication system are discussed. The method according to an embodiment includes receiving a cell-specific sequence hopping parameter from a base station. The cell-specific sequence hopping parameter is used to enable a sequence hopping for a plurality of UEs in a cell if a cell-specific group hopping parameter is used to disable a group hopping for the plurality of UEs in the cell. The method includes receiving a UE-specific sequence group hopping (SGH) parameter, specified to the UE, from the base station. The UE-specific SGH parameter is used to disable the sequence hopping, enabled by the cell-specific sequence hopping parameter. The method includes generating the reference signal sequence based on a base sequence number within a base sequence group. The base sequence number within the base sequence group is determined by the UE-specific SGH parameter.
