An unmanned aerial vehicle, UAV, is an aerial vehicle without a directing pilot and is controlled remotely by humans. UAVs have applications in emergency rescue missions, surveillance, package delivery, and weather and traffic management. UAVs can also be used to improve the characteristics of wireless or mobile communication technologies. It can also be used as a wireless access point in wireless ground communications. To turn the above applications into reality, UAV requires control over wireless transmission channels to operate remotely and safely. The radio propagation standard characteristics in which it operates are entirely different from the conventional ground users (GUEs). Considering all these challenges, studies have been taking place with the aim of cooperating with UAV communication in today’s wireless mobile networks. Reconfigurable intelligent surfaces are emerging hardware technology that can be used to improve transmission medium characteristics and improve energy efficiency. RIS can be used in wireless networks to generate a smart radio environment. By using RIS, it enables the user to configure the transmission of electromagnetic waves in a user-programmable manner. RIS can receive radio signals from the transmitter and beamform inactively toward the receiver by inciting a manageable phase shift. This increases the signal energy and improves the data rate also. RIS can control the wireless transmission channels partially and provide us with more favorable propagation characteristics. For this reason, it is well suited for UAV cellular communications by which it is possible to improve the communication quality and provide a reconfigurable propagation environment.
