The present invention relates to the technical field of mobile communications, and in particular, to a feedback method and apparatus of channel state information. The method comprises: a user equipment acquiring first channel state information on the basis of a first channel state information measurement resource, configured by a base station and correspondingly indicating a horizontal dimension, of a first antenna port; acquiring second channel state information on the basis of a second channel state information measurement resource, configured by the base station and correspondingly indicating a vertical dimension, of a second antenna port; and feeding back channel state information to the base station, comprising: feeding back the first channel state information to the base station in a first feedback mode, and feeding back the second channel state information to the base station in a second feedback mode, wherein the second feedback mode is different from the first feedback mode; or feeding back third channel state information in a third feedback mode, wherein the third channel state information is obtained by the user equipment on the basis of the first channel state information and the second channel state information. |
