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 issue how uplink feedback is performed when downlink bandwidth is different from uplink bandwidth.
Claims20
An uplink feedback method, comprising:
- detecting, by a 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 using for transmitting feedback information for one of the at least two consecutive downlink sub-frames, the joint uplink feedback information for the at least two consecutive downlink sub-frames.
An uplink feedback method, comprising:
- transmitting, by a base station, downlink data to a user equipment;
- and
- receiving, by the base station in an uplink sub-frame using for transmitting feedback information for one of at least two consecutive downlink sub-frames, joint uplink feedback information responding to the at least two consecutive downlink sub-frames from the user equipment.
A user equipment, comprising a processor coupled with a non-transitory storage medium storing executable instructions;
- wherein the executable instructions, when executed by the processor, cause the processor to:
- detect downlink data in at least two consecutive downlink sub-frames;
- jointly encode feedback signals responding to the downlink data in the at least two consecutive downlink sub-frames to obtain joint uplink feedback information;
- and
- transmit in an uplink sub-frame using for transmitting feedback information for one of the at least two consecutive downlink sub-frames, the joint uplink feedback information for the at least two consecutive downlink sub-frames.
An apparatus, comprising a processor coupled with a non-transitory storage medium storing executable instructions;
- wherein the executable instructions, when executed by the processor, cause the processor to:
- transmit downlink data to a user equipment;
- and
- receive in an uplink sub-frame using for transmitting feedback information for one of at least two consecutive downlink sub-frames, joint uplink feedback information responding to the at least two consecutive downlink sub-frames and transmitted by the user equipment.
