The present invention provides an aperiodic channel quality information sending method and a mobile terminal. The method comprises: a mobile terminal and network side pre-appointing one or more transmission modes which support the forming of dual flow beam, and aperiodic channel quality information CQI feedback mode(s) corresponding to the transmission modes; the network side indicating the mobile terminal with one pre-appointed transmission mode to be adopted, wherein when the mobile terminal receiving the indication of adopting the one pre-appointed transmission mode, the mobile terminal adopts the aperiodic CQI feedback mode corresponding to the one pre-appointed transmission mode to feed back the CQI information to the network side. The method of the present invention facilitates the reduction of signaling overhead and feedback overhead, the increase of the feedback dimensionality of the channel information, and the improvement of the throughput of the system. |
