Including the feedback method, the present invention provides a channel of information: at least one time, determine the current channel information corresponding to at least one data stream relative to the channel information of a previous time difference information; the difference of information feedback. The invention also provides a feedback device for channel information. In the invention, differential information of channel information corresponding to at least one data stream is fed back. Because of the difference of information channel information relative to the amount of information of the channel information to be small, so the number of bits used by the feedback channel information difference of information than the number of bits used in the feedback channel information, thus saving the cyber source.
