Method and apparatus for transmitting HARQ feedback information, base station and terminal

A method of transmitting downlink Hybrid Automatic Repeat reQuest (HARQ) feedback information, being applicable to a base station, and comprising:

• determining downlink HARQ configuration information, wherein the downlink HARQ configuration information informs at least two preset terminals about transmission configuration information of target downlink control signaling, the target downlink control signaling carries pieces of downlink HARQ feedback information for the at least two preset terminals, and a piece of the downlink HARQ feedback information is HARQ feedback information with respect to uplink data transmission from a terminal;
• sending the downlink HARQ configuration information to each of the at least two preset terminals;
• loading the downlink HARQ feedback information for each of the at least two preset terminals into the target downlink control signaling according to the downlink HARQ configuration information;
• and
• sending the target downlink control signaling to each of the at least two preset terminals,
• wherein the downlink HARQ configuration information comprises identification information of the target downlink control signaling and configuration information of information fields;
• wherein the identification information of the target downlink control signaling informs the at least two preset terminals about how to identify the target downlink control signaling;
• and
• wherein the configuration information of the information fields instructs the at least two preset terminals to search for corresponding target information fields from preset locations in the target downlink control signaling;
• wherein determining the downlink HARQ configuration information comprises:
• determining terminal information corresponding to the target downlink control signaling, wherein the terminal information comprises at least a terminal identifier of each of the at least two preset terminals;
• and
• determining configuration information of an information field for each of the at least two preset terminals according to the terminal information.
