Abstract

本申请公开一种反馈参数上报方法和装置，方法包括：终端设备获取基站下发的天线形态配置参数和正交基生成控制参数；根据这些参数生成至少两个正交基，每个所述正交基的构造与基站侧的天线形态有关；接收来自基站的下行信道状态信息参考信号CSI‑RS，根据CSI‑RS确定信道参数；选择目标正交基；以及所述信道参数和目标正交基提取反馈参数，并将其上报给所述基站，其中，所述反馈参数的参数个数小于所述信道参数的个数。由于该目标正交基做投影映射后的向量或者矩阵中存在少量幅度较大值，进而将这些幅度较大值等信息作为反馈参数上报给基站，避免将所有特征向量元素都上报，从而减少了上行反馈所占用的承载资源，节约了资源开销。
