Hybrid Automatic Repeat Request-Acknowledgement Information Feedback Method, Terminal Device, and Network Device

A hybrid automatic repeat request-acknowledgement (HARQ-ACK) information feedback method, the method comprising:

• performing, by a communication device, data channel detection on a first downlink subframe;
• performing, by the communication device, data channel detection on a second downlink subframe, wherein the second downlink subframe does not overlap with the first downlink subframe in time domain;
• sending, by the communication device, first HARQ-ACK information to a network device by using a first uplink channel when determining that the first downlink subframe comprises a first downlink data channel and that the second downlink subframe does not comprise a second downlink data channel,
• wherein the first HARQ-ACK information indicates a receiving status of the first downlink data channel, and
• wherein a first length of a time domain resource corresponding to the first downlink data channel is greater than a second length of a time domain resource corresponding to the second downlink data channel;
• and
• sending, by the communication device, second HARQ-ACK information to the network device by using a second uplink channel when determining that the first downlink subframe comprises the first downlink data channel and that the second downlink subframe comprises the second downlink data channel,
• wherein the second HARQ-ACK information indicates the receiving status of the first downlink data channel, and
• wherein a radio resource occupied by the first uplink channel is different from that occupied by the second uplink channel.

A device comprising:

• a non-transitory memory storing program instructions;
• and
• at least one processor in communication with the memory, wherein the at least one processor is configured to execute instructions to:
• perform data channel detection on a first downlink subframe;
• perform data channel detection on a second downlink subframe, wherein the second downlink subframe does not overlap with the first downlink subframe in t time domain;
• and
• send first hybrid automatic repeat request-acknowledgement (HARQ-ACK) information to a network device by using a first uplink channel when a detector determines that the first downlink subframe comprises a first downlink data channel and that the second downlink subframe does not comprise a second downlink data channel,
• wherein the first HARQ-ACK information indicates a receiving status of the first downlink data channel, and
• wherein that a first length of a time domain resource corresponding to the first downlink data channel is greater than a second length of a time domain resource corresponding to the second downlink data channel;
• and
• send second HARQ-ACK information to the network device by using a second uplink channel when the detector determines that the first downlink subframe comprises the first downlink data channel and that the second downlink subframe comprises the second downlink data channel,
• wherein the second HARQ-ACK information indicates the receiving status of the first downlink data channel, and
• wherein a radio resource occupied by the first uplink channel is different from that occupied by the second uplink channel.

A non-transitory computer-readable storage medium comprising instructions which, when executed by a computer hardware, cause the computer hardware to:

• perform data channel detection on a first downlink subframe;
• perform data channel detection on a second downlink subframe, wherein the second downlink subframe does not overlap with the first downlink subframe in time domain;
• and
• send first hybrid automatic repeat request-acknowledgement (HARQ-ACK) information to a network device by using a first uplink channel when a detector determines that the first downlink subframe comprises a first downlink data channel and that the second downlink subframe does not comprise a second downlink data channel,
• wherein the first HARQ-ACK information indicates a receiving status of the first downlink data channel, and
• wherein a first length of a time domain resource corresponding to the first downlink data channel is greater than a second length of a time domain resource corresponding to the second downlink data channel;
• and
• send second HARQ-ACK information to the network device by using a second uplink channel when the detector determines that the first downlink subframe comprises the first downlink data channel and that the second downlink subframe comprises the second downlink data channel,
• wherein the second HARQ-ACK information indicates the receiving status of the first downlink data channel, and
• wherein a radio resource occupied by the first uplink channel is different from that occupied by the second uplink channel.
