Abstract

一种信道信息传输装置、方法和***，以提高信道信息的反馈精度。一种第一设备，包括：接收模块，用于接收来自第二设备的参考信号；处理模块，用于根据参考信号得到预编码矩阵，以及生成用于指示预编码矩阵的第一信道信息和第二信道信息；发送模块，用于向第二设备发送第一信道信息和第二信道信息；其中，第一信道信息的精度比第二信道信息的精度高；第一信道信息包括预编码矩阵的每一个元素的相位信息，第二信道信息包括预编码矩阵的每一个元素的幅度信息。对于还原信道矩阵比较关键、精度要求高的预编码矩阵的相位信息比幅度信息的精度高，一方面可以降低信道信息反馈的开销，另一方面，还能够保证信道信息反馈的精度。
