在无线通信的两个通信节点之间，第一通信节点向第二通信节点传输信号，第二通信节点向第一通信节点反馈信道状态信息，第一通信节点根据接收到的信道状态信息确定传输方案，从而提高传输的效率。如图1所示：例如，基站向终端传输信号，终端向基站反馈信道状态信息。再例如，第一基站向第二基站传输信号，第二基站向第一基站反馈信道状态信息。再例如，第一终端向第二终端传输信号，第二终端向第一终端反馈信道状态信息。
在无线通信中，第一通信节点以空分复用的方式向第二通信节点传输多层信号，这样提高了通信的效率。第一通信节点将信号通过预编码矩阵映射到天线端口上传输，传输多层信号；这样所传输的各层信号与预编码矩阵中的各列矢量分别对应。其中一个特殊的情况是，第一通信节点向第二通信节点传输一层信号。其中第一通信节点依据所接收到的第二通信节点反馈的信道状态信息确定空分复用的传输方案。其中，第二通信节点反馈的信道状态信息包括预编码矩阵的信息。

具体而言，第一目标频带是预编码矩阵信息的适用频带，也就是预编码矩阵信息是为这些频带反馈的。第二目标频带是信道状态信息中除预编码矩阵信息以外的其它信道状态信息的适用频带，也就是其它信道状态信息是为这些频带反馈的。其它信道状态信息，例如包括信道质量指示信息，例如包括信道强度信息。第二通信节点确定第一目标频带，才能精确地确定目标频带上的预编码矩阵信息，从而精确地反馈所述目标频带上的预编码矩阵信息。第二通信节点确定第二目标频带，才能精确地确定信道状态信息中除预编码矩阵信息以外的其它信道状态信息，从而精确地反馈对应目标频带上的其它信道状态信息。第一通信节点获取第一目标频带，才能准确确定所接收到的预编码矩阵信息所适用的频带，从而确定适当的预编码使用方案。第一通信节点获取第二目标频带，才能准确确定所接收到的其它信道状态信息所适用的频带，从而确定适当的其它信道状态信息使用方案。
