1. A hybrid automatic repeat request (HARQ) feedback method, applied in a base station, comprising:
configuring target indication information for a terminal, wherein the target indication information indicates frequency domain resource identification information corresponding to at least one first candidate frequency domain resource;
sending the target indication information to the terminal; and
after a physical downlink shared channel (PDSCH) is sent to the terminal, receiving an HARQ result for the PDSCH fed back by the terminal through a target frequency domain resource;
wherein the target frequency domain resource comprises a frequency domain resource for carrying the HARQ result determined by the terminal from a preset frequency domain resource and the at least one first candidate frequency domain resource.
