The article proposes new methods to jointly apply IRS and UAV in integrated air-ground wireless networks, exploiting their complementary advantages and addressing the different limitations they face in practice, achieving better communication performance.
Intelligent reflecting surface (IRS) and unmanned aerial vehicle (UAV) have emerged as two promising technologies to boost the performance of wireless communication networks by proactively altering wireless communication channels via smart signal reflection and maneuver control, respectively. However, they face different limitations in practice, which restrain their future applications. In this article, we propose new methods to jointly apply IRS and UAV in integrated air-ground wireless networks by exploiting their complementary advantages. Specifically, the terrestrial IRS is used to enhance the UAVground communication performance, while the UAV-mounted IRS is employed to assist in terrestrial communication. We present their promising application scenarios, new communication design issues, as well as potential solutions. In particular, we show that it is practically beneficial to deploy both terrestrial and aerial IRSs in future wireless networks to reap the benefits of smart reflections in 3D space.
