    • A method and device for reporting channel quality indicator, the method comprising: select a channel quality indicator CQI from channel bandwidth as reference information (101); differentially modulate the CQI information and the reference information of the resource port to be reported, respectively, to obtain CQI difference information of the resource port (102); obtain difference CQI grade of the resource port on the basis of the CQI difference information of the resource port and a difference CQI grade-CQI difference information cross-reference list (103,104,105); and report the reference information and the difference CQI grade of the resource port to base station (106). The device comprises a differential modulator (301, 401), a CQI information processor (302, 402) and a transmitter (303, 403). The invention can report CQI information of all resource ports in a whole channel, and meanwhile keep signaling length reported every time to be changeless, so as to simplify the process for signaling decoding. And it can also report CQI information of several resource ports whose channel quality is best, and keep channel quality report to be correct at the time of economizing signaling cost.
