<p>A method and device for feeding channel status information back and determining a multipoint cooperation mode belong to communications technology field. The method for feeding the channel status information back includes: obtaining a plurality of channel status information of a plurality of cells in the multipoint cooperation mode (101); selecting preset amount of uncorrelated channel status information from the plurality of channel status information, and feeding the selected channel status information back to the corresponding network side device (102). By feeding the uncorrelated channel status information back to the corresponding network side device by a terminal device, the embodiment of the present invention enables the network side device to calculate the rest channel status information in the multipoint cooperation mode according to the received channel status information and further to select the multipoint cooperation mode with the best channel status from more channel status information, so as to ensure the quality of transmitting downstream data information.</p> |
