The present invention discloses an information multiplexing method, comprising: coding multiple feedback information according to number of the feedback information and a linear block code sequence, and truncating corresponding coded information according to a target length of the feedback information coded (S302); dividing the truncated coded information into multiple feedback information logic units sequentially, and multiplexing together the multiple feedback information logic units, multiple rank indication information logic units, multiple control information logic units and data information logic units are; wherein the control information logic units, the multiple rank indication information logic units, the data information logic units, and the feedback information logic units contain the same bit number (S304). Transmission of more than two ACK/NACKs is achieved by the present invention and transmission performance of the system is improved.
