Patent attributes
The present disclosure relates to an unmanned aerial vehicle (UAV), a terrestrial station thereof and a data transmission method. A data transmission method is applied to a terrestrial station and the method includes: receiving data packets continuously sent by a UAV; detecting continuity of data packet sequence numbers of the received data packets; and sending a data packet retransmission request to the UAV according to a lost data packet sequence number if it is detected that the data packet sequence numbers corresponding to the data packets are discontinuous. Adopting the UAV, the terrestrial station and the data transmission method that are provided in the present disclosure can effectively improve utilization of an uplink transmission link.
