Abstract

本申请实施例提供一种信道信息处理方法、设备及存储介质，终端设备接收网络设备发送的下行参考信号，并根据该下行参考信号进行信道估计得到信道估计的下行信道信息，进一步，向网络设备发送量化后的下行信道信息和信道估计的下行信道信息之间的误差信息、以及信道估计的下行信道信息的量化信息，使得网络设备可根据该误差信息和该信道估计的下行信道信息的量化信息重构得到重构的下行信道信息，由于重构的下行信道信息的准确性高于量化后的下行信道信息的准确性，当网络设备根据该重构出的下行信道信息确定终端设备对应的预编码矩阵时，可提高预编码矩阵的准确性，网络设备根据预编码矩阵对下行数据进行预编码，从而提高网络设备的下行传输性能。
