Data returning method and device, terminal, unmanned aerial vehicle and readable storage medium

Abstract

The invention relates to a data returning method and device, a terminal, an unmanned aerial vehicle and a readable storage medium. The method comprises the steps that a terminal receives a downlink control signal issued by an unmanned aerial vehicle according to a preset frame structure, the downlink control signal carries an instruction used for indicating the terminal to receive and analyze service data, and the terminal is in wireless direct connection communication with the unmanned aerial vehicle; Wherein the preset frame structure comprises a downlink control channel sub-frame for directly transmitting a downlink control signal, an uplink control channel sub-frame for directly transmitting an uplink control signal and a service channel sub-frame for directly transmitting service data; And the terminal sends a response to the unmanned aerial vehicle on a frequency domain resource corresponding to the uplink control channel subframe according to the downlink control signal, and receives service data directly transmitted by the unmanned aerial vehicle on the frequency domain resource corresponding to the service channel subframe. By adopting the method, the unmanned aerial vehicle can directly return the service data to the terminal, base station transfer is not needed, the physical structure is simple, and the robustness is high.

Description

technical field [0001] The present application relates to the field of communication technology, and in particular to a data return method, device, terminal, unmanned aerial vehicle and readable storage medium. Background technique [0002] With the development of UAV technology, more and more fields have begun to use UAVs for cruising shooting, acquiring image information of targets, and returning the image information for analysis and application. [0003] Generally, the UAV can transmit the UAV status data or the image data and video data obtained by the UAV to the UAV ground controller, computer or mobile phone and other terminals through the base station to realize data return. [0004] However, the above data return method needs to be relayed through the base station, the physical structure is complex, and there is a problem of poor robustness. Contents of the invention [0005] Based on this, it is necessary to provide a simple physical structure and high robustnes...
