Claim:
1. An uplink feedback method, comprising: detecting, by user equipment, downlink data in at least two consecutive downlink sub-frames; joint encoding, by the user equipment, feedback signals responding to the downlink data in the at least two consecutive downlink sub-frames to obtain joint uplink feedback information; 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, the joint uplink feedback information for the at least two consecutive downlink sub-frames; wherein a sum of lengths of the at least two consecutive downlink sub-frames on a single carrier is equal to a length of the uplink sub-frame; and at least one of: a downlink bandwidth is different from an uplink bandwidth; and an uplink transmission time interval is greater than a downlink transmission time interval.
