Reconfigurable intelligent surface (RIS) is one of the potential key technologies for sixth generation (6G) communications, which has the characteristics of low cost, low complexity, and easy deployment. By applying control signals to adjustable elements on the electromagnetic unit, it has the ability to adjusting the wireless communication environments, which provides a new opportunity to improve the high energy-efficiency performance of wireless communication systems. This paper provides a comprehensive overview of channel modeling and characteristics analysis for RIS-assisted unmanned aerial vehicle (UAV) high energy-efficiency communications. Firstly, based on the research basis of the UAV communications technologies, we clarify the necessities of introducing the RIS into UAV communications. Then, we summarize the key technologies for channel modeling and characteristics analysis for RIS-assisted UAV communications. Finally, we point out some future research directions in RIS-assisted UAV channel modeling and characteristics analysis. |
