1. A hybrid automatic repeat request (HARQ) feedback enhancement method, comprising:
sending downlink control information comprising first indication information to a terminal,
wherein the first indication information is used for indicating a quantity of downlink transmission blocks received by the terminal on a subframe after a current subframe and a subcarrier after a current subcarrier in a current hybrid automatic repeat request (HARQ) feedback window;
wherein the downlink control information further comprises second indication information, the second indication information is used for indicating the terminal to send HARQ feedback of first transmission blocks and/or HARQ feedback of second transmission blocks, the first transmission blocks are the transmission blocks decoded by a first codebook currently using, and the second transmission blocks are the transmission blocks decoded by a second codebook used before the first codebook; and
wherein numerical information determined by a bit number occupied by the second indication information is used for indicating the terminal is to determine the quantity of the second transmission blocks conducting HARQ feedback when HARQ feedback of the first transmission blocks and HARQ feedback of the second transmission blocks are sent.
