    Abstract: Example channel feedback information transmission methods are disclosed. In one example method, a terminal performs channel estimation on a subcarrier on which a downlink pilot is located, and obtains first channel information. The terminal performs a channel interpolation calculation on a channel of a data subcarrier according to the first channel information, and obtains second channel information according to a result of the channel interpolation calculation. The terminal determines a feedback factor, and obtains third channel information from the second channel information according to the feedback factor, where an amount of the third channel information is less than an amount of the second channel information. The terminal feeds back the third channel information to a base station. Some channel information is selected and fed back by means of a feedback factor.
