Title: CHANNEL INFORMATION REPORTING METHOD, APPARATUS AND SYSTEM
Abstract:
A channel information reporting method, apparatus and system, for use in improving adaptive performance of a link. A first device comprises: a reception module, used for receiving a reference signal from a second device; a processing module, used for performing channel estimation according to the reference signal, so as to obtain a channel matrix; decomposing the channel matrix to obtain a precoding matrix that is not quantized; and generating channel information used for describing the precoding matrix that is not quantized; and a sending module, used for sending, to the second device, the channel information used for describing the precoding matrix that is not quantized. Because the second device sends the channel information used for describing the precoding matrix that is not quantized, so that quantization errors are avoided, so that the precoding matrix obtained by the first device is more accurate, thereby effectively improving adaptive performance of a link.
