    • The present invention relates to a Multi-Input Multi-Output (MIMO) communication system and more particularly, to a method for Correlation matrix feedback in a multi-cell wireless communication system. A method for transmitting correlation matrix feedback information of a mobile station considering adaptive feedback mode in a multi-cell wireless communication system according to one embodiment of the present invention comprises measuring a channel between the mobile station and a serving base station using a signal received from the serving base station; determining a first matrix indicating channel state information and a first precoder using the measured channel; generating a second matrix using a Fourier matrix and the first matrix; and transmitting feedback information including at least one of information of the first precoder and diagonal values of the second matrix.
    • 多输入多输出(MIMO)通信系统技术领域本发明涉及多输入多输出(MIMO)通信系统,更具体地说,涉及一种用于多小区无线通信系统中的相关矩阵反馈的方法。 在根据本发明的一个实施例的在多小区无线通信系统中考虑自适应反馈模式的移动站的相关矩阵反馈信息的传输方法包括:使用接收到的信号来测量移动站与服务基站之间的信道, 服务基站; 使用所测量的信道确定指示信道状态信息的第一矩阵和第一预编码器; 使用傅立叶矩阵和所述第一矩阵生成第二矩阵; 以及发送包括第一预编码器的信息和第二矩阵的对角线值中的至少一个的反馈信息。
