<p>Disclosed are a data transmission method and device, mainly comprising: determining downlink data scheduled by a downlink hybrid automatic repeat request (HARQ) process corresponding to the uplink feedback message sent by a terminal device based on a first cell device receiving an uplink feedback message sent by a second cell device, and according to the time information associated with the uplink feedback message and determined by the second cell device contained in the received uplink feedback message. As a result, for the uplink feedback message sent by the terminal device, the first cell device accurately determines the downlink data scheduled by the HARQ process corresponding to the uplink feedback message sent by the terminal device by receiving the time information associated with the uplink feedback message and determined by the second cell device and the time relationship with the second cell device, thus overcoming the difficulty in determining for which downlink data scheduled by the HARQ process the received uplink feedback message is fed back, and improving scheduling capability of the downlink data.</p> |
