Abstract

A method and system for feeding back channel information to coordinated cells, the method including: measuring channel qualities of downlink channels between coordinated cells and user equipment; classifying the coordinated cells into different coordinated cell classes according to the measured channel qualities; based on different channel quality intervals corresponding to different coordinated cell classes, respectively selecting channel information feedback modes with different feedback enhancement degrees for different coordinated cell classes; and using the selected channel information feedback modes with different feedback enhancement degrees to determine the channel information to be fed back to the coordinated cells in each coordinated cell class according to a pre-determined order, and sending the determined channel information to the coordinated cells.
