The embodiments relate to the wireless communication field, and a data transmission control method and a data transmission device are provided. The method includes: receiving from a sender and buffering data in a buffer, and then forwarding the buffered data to a receiver; receiving an acknowledgement (ACK) returned by the receiver, where the ACK indicates that the data is received; adding or reducing the ACK returned by the receiver according to a volume of data unsent in the buffer; and sending the processed ACK to the sender. The data sending rate of the sender is controlled by the processed ACK. This makes the data transmission be reliable and highly efficient. |
