Intelligent reflecting surfaces-assisted petahertz mobile communication system

This paper proposes an intelligent reflecting surfaces (IRSs)-assisted Petahertz mobile communication system. The IRSs are utilized in this system to assist the base station for beam tracking and reduce the impact of obstacles by path replanning and real-time power distribution. The scheme of auxiliary beam deflection and tracking is purposed based on the working principle of phase controlled IRSs. Since signals can be deflected freely among multiple IRSs, two multi-path power allocation schemes for optimal system performance are also proposed. Experiments and simulation are presented for verification.
