Abstract
The present invention discloses a method for feeding back channel information, which includes: configuring a same codebook space at a data transmitting end and a data receiving end (101); the data receiving end selecting, from the codebook space, a codeword matched with a channel, and transmitting a sequence number corresponding to the codeword to the data transmitting end (102); and the data transmitting end extracting, according to the sequence number, a corresponding codeword from a locally-configured codebook space to obtain channel state information (103). The present invention also discloses a system for feeding back channel information, which includes a data transmitting end and a data receiving end. The method and system for feeding back channel information solve the problem that there is no channel information feedback method for dual-polarized channels.
