Abstract

本申请公开了一种通信方法、终端及基站，方法包括：终端接收基站发送的指示信息，指示包含在第一预编码矩阵集合中的预编码矩阵以及预编码矩阵对应的传输秩，预编码矩阵用于将r个传输层上的发射数据流进行预编码得到在终端的N个传输端口上发送的信号；当r＞1时，第一预编码矩阵集合中传输秩为r的预编码矩阵的非标量部分，是由r个预编码矩阵的非标量部分的列合并而成，r个预编码矩阵是从传输秩为1的所有预编码矩阵中选取的预编码矩阵；终端根据指示信息，确定对发射数据流进行预编码的预编码矩阵。秩>1的预编码矩阵由秩＝1的预编码矩阵拼接而成，可以降低终端的实现复杂度，保证较小的下行信令指示开销和较优的传输性能。
