Relay device based on cognitive radio communication UAV for including the same and Relay method based on cognitive radio communication using the UAV

摘要

Disclosed is a cognitive wireless communication-based relay device, an unmanned aerial vehicle including the same, and a cognitive wireless communication-based relay method using the unmanned aerial vehicle. The disclosed relay device is a relay device attached to the unmanned aerial vehicle, a communication unit for sensing a channel near the space where the unmanned aerial vehicle is located, and performing data communication with an external device; And controlling the communication unit, calculating a location where a frequency resource that can be used is the maximum based on the channel sensing result, and managing the calculated location through the communication unit when the unmanned aerial vehicle is present in the calculated location. Containing a base station and the cognitive radio communication based channel use negotiation; includes, but, when occupying the frequency resource A through the channel use negotiation, the control unit to provide a short-range wireless communication signal using the frequency resource A Control.
