The present invention relates to the field of mobile communications technologies, and in particular, to a feedback method and apparatus of channel state information. The method includes: acquiring, by user equipment, first channel state information based on a first channel state information measurement resource that is configured by a base station and that corresponds to a first antenna port representing a horizontal dimension; and acquiring, based on a second channel state information measurement resource, which is configured by the base station, of a second antenna port representing a vertical dimension, second channel state information; and feeding back channel state information to the base station, which includes: feeding back the first channel state information to the base station according to a first feedback mode, and feeding back the second channel state information to the base station according to a second feedback mode, where the second feedback mode is different from the first feedback mode; or feeding back third channel state information according to a third feedback mode, where the third channel state information is obtained by the user equipment and based on the first channel state information and the second channel state information. |
