Abstract

本发明涉及时分双工复用多输入多输出系统中的信号发送方法及装置。根据本发明的第一方面，提供了一种在时分双工复用多输入多输出系统的基站中用于发送信号的方法，包括以下步骤：A.接收来自一个空分复用分组的用户终端的信号并根据接收到的信号估计上行信道传输特性；B.确定上行信道传输特性与下行信道传输特性之间的互逆性校准信息；C.根据上行信道特性和校准信息采用迫零法来确定下行预编码矩阵并根据所确定的下行预编码矩阵向所述空分复用分组的用户终端发送下行信号；其中，所述步骤B还包括接收所述空分复用分组的用户终端所反馈的与下行向量信道矩阵有关的信息，并根据所述与下行向量信道矩阵有关的信息选择性地更新校准信息。
