Embodiments of the present invention provide a data transmission method, apparatus, and device. The method includes: receiving a P th piece of hybrid automatic repeat request HARQ process data sent by a data transmit end at an N th moment, where P is a positive integer greater than or equal to 1, and N is a positive integer greater than or equal to 1; and sending Q pieces of hybrid automatic repeat request feedback HARQ-ACK information to the data transmit end at an M th moment, where the Q pieces of HARQ-ACK information are feedbacks corresponding to Q pieces of HARQ process data whose HARQ-ACK information is not received by the data transmit end before the M th moment, the Q pieces of HARQ-ACK information include a P th piece of HARQ-ACK information corresponding to the P th piece of HARQ process data, and M is a positive integer greater than N. According to the method provided in the present invention, a frequency spectrum resource of a carrier aggregation system between base stations can be fully used, which improves a peak transmission rate of a user. |
