  Intelligent reflecting surfaces (IRSs) with the ability to reconfigure
inherent electromagnetic reflection and absorption characteristics in real-time
provide unparalleled prospects to improve wireless connectivity in adverse
circumstances. Unmanned aerial vehicles (UAV)-assisted wireless networks are
evolved as a reliable solution to combat non-line of sight (NLoS) scenarios.
Thereby, the IRS-empowered UAV-assisted cellular networks will be a significant
role-player to improve the coverage and user experiences. The paper aimed to
minimize the path loss and maximize the achievable data rate in
IRS-UAV-assisted networks. In this context, the work analyzed path loss and
achievable rate utilizing millimeter wave (mmWave) carrier considering the
conventional UAV model and IRS-empowered UAV communication model. The research
obtained that the IRSempowered UAV communications model can significantly
minimize path loss and maximize the achievable data rate compared to the
conventional UAV-assisted model.
