Claim:
An aperiodic channel quality information sending method comprises: a mobile terminal pre-appointing one or more transmission modes which support the forming of dual flow beam and aperiodic channel quality information CQI feedback mode corresponding to the transmission modes with a network side; the mobile terminal receiving an indication of adopting the one pre-appointed transmission mode from the network side, and adopting the aperiodic CQI feedback mode corresponding to the one pre-appointed transmission mode to feed back the CQI information to the network side; wherein the step of the mobile terminal and the 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 corresponding to the transmission modes comprises: the mobile terminal and the network side pre-appointing that a transmission mode 8 supports the forming of dual flow beam which needs or does not need the pre-coding information feedback, wherein the aperiodic CQI feedback mode of the transmission mode 8 is the feedback mode 2-0, the feedback mode 3-0, the feedback mode 1-2, the feedback mode 2-2 or the feedback mode 3-1; and in the step of feeding back the CQI information to the network side, the mobile terminal also adopts the aperiodic CQI feedback mode corresponding to the one pre-appointed transmission mode to feed back the pre-coding information PMI to the network side when the PMI is needed wherein the step of adopting the aperiodic CQI feedback mode corresponding to the one pre-appointed transmission mode to feed back the CQI information to the network side comprises: adopting the feedback mode 2-0 or the feedback mode 3-0 to feed back the CQI information of the first flow; or adopting the feedback mode 1-2, the feedback mode 2-2 or the feedback mode 3-1 to feed back the CQI information, the rank RI information and the PMI information of each flow.
