Abstract
The present invention provides a data transmission method, device, and system, and relates to the communications field, which can improve data transmission efficiency. The method includes: determining, by a second base station, that statuses of all HARQ processes in a first hybrid automatic repeat request HARQ buffer are occupied states; and sending, by the second base station, a second data block to a user equipment UE by using an HARQ process in an idle state in a second HARQ buffer, where the first HARQ buffer and the second HARQ buffer are different HARQ buffers disposed in the second base station. The data transmission method, device, and system are applicable to data transmission in carrier aggregation.
