    • A rotating reference codebook used in a multiple input multiple output (MIMO) communication system is provided. The reference codebook includes codewords from a discrete Fourier transform (DFT) codebook. A base station and a terminal may calculate a rotation matrix based on a previous preferred codeword and a random codeword among codewords included in the DFT codebook. A reference codebook may be rotated using the rotation matrix and may be transformed to a new codebook. The reference codebook may include codewords of a polar cap codebook and the codewords of the DFT codebook. Even though the codewords of the DFT codebook are rotated, the codewords of the DFT codebook may remain in the new codebook as elements of the DFT codebook.
    • 提供了一种在多输入多输出(MIMO)通信系统中使用的旋转参考码本。 参考码本包括来自离散傅里叶变换(DFT)码本的码字。 基站和终端可以基于DFT码本中包括的码字中的先前优选码字和随机码字来计算旋转矩阵。 参考码本可以使用旋转矩阵旋转并且可以被转换为新的码本。 参考码本可以包括极帽码本的码字和DFT码本的码字。 即使DFT码本的码字被旋转,DFT码本的码字也可以作为DFT码本的元素保留在新码本中。

    • A multiple input multiple output (MIMO) communication system using a first codebook and a second codebook is provided. The first codebook and the second codebook may independently exist, or may exist in a form of an overall codebook in which the first codebook and the second codebook are integrated with each other. A receiver may extract a first precoding matrix indicator from the first codebook, and may extract a second precoding matrix indicator from the second codebook. The receiver may also extract the first precoding matrix indicator and the second precoding matrix indicator from the overall codebook. The first precoding matrix indicator and the second precoding matrix indicator may be fed back to a transmitter. The transmitter may determine a precoding matrix based on the first precoding matrix indicator and the second precoding matrix indicator.
    • 提供了使用第一码本和第二码本的多输入多输出(MIMO)通信系统。 第一码本和第二码本可以独立地存在,或者可以以第一码本和第二码本彼此集成的整体码本的形式存在。 接收机可以从第一码本提取第一预编码矩阵指示符,并且可以从第二码本中提取第二预编码矩阵指示符。 接收机还可以从总码本中提取第一预编码矩阵指示符和第二预编码矩阵指示符。 第一预编码矩阵指示符和第二预编码矩阵指示符可以反馈到发射机。 发射机可以基于第一预编码矩阵指示符和第二预编码矩阵指示符来确定预编码矩阵。
