Uplink feedback method, user equipment, and base station

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 used 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;
• wherein length of the uplink sub-frame used for transmitting the feedback information is N multiplied by length of one downlink sub-frame in the at least two consecutive downlink sub-frames, wherein N is an integer greater than 2.

A user equipment, comprising:

• a receiver;
• a transmitter;
• and
• a processor coupled to a non-transitory computer-readable storage medium storing executable instructions, such that when the executable instructions are executed by the processor, the processor facilitates performing:
• detecting, by the receiver, downlink data in at least two consecutive downlink sub-frames;
• jointly encoding 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 transmitter, in an uplink sub-frame used 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;
• wherein length of the uplink sub-frame used for transmitting the feedback information is N multiplied by length of one downlink sub-frame in the at least two consecutive downlink sub-frames, wherein N is an integer greater than 2.

An apparatus, comprising;

• a receiver;
• a transmitter;
• and
• a processor coupled to a non-transitory computer-readable storage medium storing executable instructions, such that when the executable instructions are executed by the processor, the processor facilitates performing:
• transmitting, by the transmitter, downlink data to a user equipment;
• and
• receiving, by the receiver, in an uplink sub-frame used 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;
• wherein length of the uplink sub-frame used for transmitting the feedback information is N multiplied by length of one downlink sub-frame in the at least two consecutive downlink sub-frames, wherein N is an integer greater than 2.
