Hybrid automatic repeat request (HARQ) feedback method and apparatus

A hybrid automatic repeat request (HARQ) feedback method, being applicable to a Machine Type Communication (MTC) device, comprising:

• determining a plurality of target HARQ results;
• wherein the plurality of target HARQ results correspond to a plurality of respective target physical downlink shared channels (PDSCHs) which are scheduled by a current physical downlink control channel (PDCCH);
• determining, based on the plurality of target HARQ results, one target physical uplink control channel (PUCCH) from a plurality of candidate PUCCHs and a combined HARQ result;
• wherein the target PUCCH comprises a target resource carrying the combined HARQ result, and the combined HARQ result and the target resource are configured to represent the plurality of target HARQ results;
• and
• sending the target PUCCH that comprises the target resource carrying the combined HARQ result to a base station.

A hybrid automatic repeat request (HARQ) feedback apparatus, being applicable to a Machine Type Communication (MTC) device, comprising:

• a processor;
• and
• memory for storing instructions executable by the processor;
• wherein the processor is configured to:
• determine a plurality of target HARQ results;
• wherein the plurality of target HARQ results correspond to a plurality of respective target physical downlink shared channels (PDSCHs) which are scheduled by a current physical downlink control channel (PDCCH);
• determine a combined HARQ result based on the plurality of target HARQ results;
• wherein the combined HARQ result is configured to represent the plurality of target HARQ results;
• determine one target physical uplink control channel (PUCCH);
• wherein the target PUCCH comprises a target resource carrying the combined HARQ result;
• and
• send the target PUCCH that comprises the target resource carrying the combined HARQ result to a base station.
