    • Provided is a communication system for a multi-cell cooperative communication. A serving base station and at least one neighboring base station may communicate with at least one terminal through mutual cooperation. Each of the serving base station and the at least one neighboring base station may shift a phase of at least one element among elements included in a precoding matrix, using a phase shift matrix, and precode at least one data symbol. A terminal may feed back preferred phase shift matrix information to the serving base station, so that the serving base station and the at least one neighboring base station may adaptively determine a phase shift matrix. The terminal may calculate the phase shift matrix with small calculation amounts. The serving base station, the at least one neighboring base station, and the terminal may pre-store a plurality of candidate matrices with respect to the phase shift matrix.
    • 提供了一种用于多小区协作通信的通信系统。 服务基站和至少一个相邻基站可以通过相互协作与至少一个终端进行通信。 服务基站和至少一个相邻基站中的每个可以使用相移矩阵来移位包括在预编码矩阵中的元素中的至少一个元素的相位,并且对至少一个数据符号进行预编码。 终端可以将优选的相移矩阵信息反馈到服务基站,使得服务基站和至少一个相邻基站可以自适应地确定相移矩阵。 终端可以以较小的计算量计算相移矩阵。 服务基站,至少一个相邻基站和终端可以相对于相移矩阵预存储多个候选矩阵。
