In order to realize the concept of massive wireless connectivity and Internet of Everything (IoE), the scientific community is focusing on technological evolution that will reach out to every corner of the world. In this context, intelligent reflecting surface (IRS) and unmanned aerial vehicle (UAV) are two prominent technologies aiming to magnify the wireless communication networks’ performance in terms of achievable data rate, reliability, security, extended coverage, and more. But all these come with some challenges. In this chapter, the authors have provided an overview of the challenges corresponding to the UAV communication system. We also discuss the possible emerging physical layer technologies corresponding to IRS-assisted UAV (IRS-UAV) systems along with their benefits and challenges. Particularly we discuss the joint optimization approaches related to the UAV trajectory and IRS passive beamformation. Finally, a case study is presented to demonstrate the importance of active and passive beamformation for a IRS-UAV system to improve the overall sum rate of the network.
