1. A data transmission method, wherein the method comprises:

  • sending, by a base station, a first data block to a user equipment (UE) by using a Hybrid Automatic Repeat Request (HARQ) process having a process number in a first HARQ buffer;

    determining, by the base station, that statuses of all HARQ processes in a first hybrid automatic repeat request HARQ buffer are in non-idle states;

    receiving, by the base station, a feedback, for the first data block, of the UE, whereinif the feedback comprises a negative acknowledgement (NACK), a second data block is a data block, corresponding to the NACK, in the first data block;

    or, if the feedback comprises an acknowledgement ACK, the second data block is a data block different from the first data block; and

    sending, by the base station, the second data block to the user equipment UE by using an HARQ process in an idle state in a second HARQ buffer, whereinthe first HARQ buffer and the second HARQ buffer are different HARQ buffers disposed in the base station.
