Provided in embodiments of the present invention are a method and device for feeding back channel information, the method comprising: determining a set of channel measurement resources, the set of channel measurement resources comprising M channel measurement resources, where M is a positive integer; performing channel measurement on the M channel measurement resources; selecting N channel measurement resources from M channel measurement resources according to the channel measurement result, where N is a positive integer, and N≤M; feeding back indication information of the selected N channel measurement resources. The embodiments of the present invention may solve the problem in the related art that a technology for selection of channel measurement resources is incapable of effectively corresponding to multiple paths, leading to low system robustness and transmission efficiency. Thus, when selecting channel measurement resources, it is possible to correspond to multiple paths, thus improving the system robustness and transmission efficiency.
