Abstract
The present invention provides an uplink feedback method, user equipment, and a base station, where the method includes: detecting, by user equipment, downlink data in at least two consecutive downlink sub-frames; performing joint encoding, by the user equipment, for a feedback for the downlink data in the at least two consecutive downlink sub-frames; and transmitting, by the user equipment in an uplink sub-frame corresponding to the last sub-frame of the at least two consecutive downlink sub-frames, joint uplink feedback information for the at least two consecutive downlink sub-frames, so as to resolve the issue of how to perform uplink feedback when downlink bandwidth is different from uplink bandwidth.
