Abstract
A codebook based channel information feedback method, device and system are provided in the present invention. The codebook based channel information feedback method includes: measuring, by a terminal in a communication system, a parameter of a downlink channel between the terminal and a base station of the communication system; selecting a plurality of precoding matrixes from a precoding codebook by using the parameter of the downlink channel, wherein a plurality of the precoding matrixes can be used by both of single-user multi-input multi-output (MIMO) transport mode and multi-user MIMO transport mode, and the precoding codebook is an aggregation of precoding matrixes; and feeding back a first information for indicating a plurality of the precoding matrixes to the base station.
