Abstract

A communication method, an unmanned aerial vehicle and a control device for the unmanned aerial vehicle. Co-existing interference can be reduced in an application scenario where multiple users coexist, thereby promoting user experience. The method in the embodiment of the present invention is used for enabling the control device for the unmanned aerial vehicle to be in communication with the unmanned aerial vehicle based on a time division duplex (TDD) mode, and comprises: in an uplink slot in the TDD mode, a control device for an unmanned aerial vehicle utilizes a first carrier to send an uplink signal to the unmanned aerial vehicle; and in a downlink slot in the TDD mode, the control device for the unmanned aerial vehicle utilizes a second carrier to receive a downlink signal sent by the unmanned aerial vehicle, wherein the first carrier corresponds to a first frequency band, the second carrier corresponds to a second frequency band, and the first frequency band and the second frequency band are not overlapped.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a communication method, an unmanned aerial vehicle and a control device for the unmanned aerial vehicle. Background technique [0002] At present, the application of unmanned aerial vehicles is penetrating into various industries, and with the increasing popularity of civilian use of unmanned aerial vehicles, providing stable point-to-point two-way communication (communication between the unmanned aerial vehicle and the control device of the unmanned aerial vehicle) in the user experience, in the air Safety requirements are becoming more and more urgent. [0003] The existing UAV control device usually adopts TDD (Time Division Duplexing, Time Division Duplexing) mode to communicate with the UAV, wherein, TDD distinguishes the wireless channel in time during the downlink operation of the frame period and the time for continuing the uplink operation. A technique where recep...
