Data sending method/transmission system, storage medium, unmanned aerial vehicle and control terminal

Abstract

The present invention provides a data transmission method / transmission system, a storage medium, an unmanned aerial vehicle and a control terminal. The method includes: using a variable-length physical layer frame structure to load narrowband data or / and broadband data for transmission; Layer frame structure includes frame synchronization part, control part, narrowband data part or / and broadband data part; frame synchronization part is used to carry frame synchronization sequence and synchronization related information; control part is used to define the channel number of narrowband data part and its level Related parameters, or / and the number of channels of the broadband data part and its first-level related parameters; the control part is used to define the detection channel position of the frame structure, the duplex mode of the frame structure, the frame length of the frame structure, or / and the frame structure Uplink and downlink channel allocation; the narrowband data part is used to carry narrowband data; the broadband data part is used to carry broadband data. The frame length of the frame structure of the present invention can be freely defined, flexibly changed, and applicable to any different application scenarios.

Description

technical field [0001] The invention belongs to the technical field of data communication and relates to a data transmission method, in particular to a data transmission method / transmission system, a storage medium, an unmanned aerial vehicle and a control terminal. Background technique [0002] The frame structure and control channel of traditional wireless data transmission usually adopt a fixed design, thus focusing on broadband or narrowband applications. Narrowbands include NB-IOT, Zigbee, etc., and broadband includes WiFi, microwave, etc. With the rapid development of the mobile Internet and the Internet of Things, the previous single narrowband transmission or broadband transmission can no longer meet the needs of increasingly rich and diverse scenarios. For example, the flight control and image transmission of drones, the access and backhaul of IoT gateways, etc., all require the system to meet the needs of large bandwidth data and video transmission while supportin...
