1. A method for hybrid automatic repeat request (HARQ) feedback, applied to a time division duplexing (TDD) machine type communication (MTC) device, the method comprising:
determining at least one target HARQ result corresponding to at least one target physical downlink shared channel (PDSCH), wherein the at least one target PDSCH comprises at least one PDSCH from all PDSCHs scheduled by a current physical downlink control channel (PDCCH), and wherein HARQ results corresponding to the at least one target PDSCH are to be fed back through a current sub-frame;
determining a target PUCCH and a combined HARQ result in at least one candidate physical uplink control channel (PUCCH) according to the at least one target HARQ result, wherein corresponding target PUCCH resource of the target PUCCH is configured to carry the combined HARQ result, and the combined HARQ result and the target PUCCH resource are configured to identify the at least one target HARQ result; and
carrying the combined HARQ result through the target PUCCH resource, and sending the target PUCCH to a base station.
