The present disclosure provides a method for transmitting hybrid automatic repeat request (HARQ) feedback information, a terminal, and a base station. The method applied in the terminal includes: acquiring preset downlink HARQ configuration information, and the preset downlink HARQ configuration information is used for informing a terminal of transmission characteristics for target downlink control signaling, and the target downlink control signaling is used for bearing HARQ feedback information for at least two uplink data transmissions of any terminal; determining feature information of the target downlink control signaling according to the preset downlink HARQ configuration information; acquiring the target downlink control signaling of the terminal according to the feature information; and parsing the target downlink control signaling to obtain HARQ feedback information for at least two uplink data transmissions.
