Abstract

Abstract:

The performance impact of Reconfigurable Intelligent Surface (RIS) technology in the practical multi-cell scenarios is analyzed based on the passive characteristics of the RIS hardware. Based on the amplitude-frequency and phase-frequency response characteristics of RIS technology, this paper proposes a statistical model for RIS reflected signals, which is a uniformed methodology to model the behavior of RIS reflections for the signals at different frequency bands. In addition, a system level simulation is provided to evaluate the interferences related to RIS assisted communication systems in the multiple cell scenarios, and an analysis and outlook on the deployment requirements for RIS assisted communication are provided.

Key words: reconfigurable intelligent surface, RIS assisted communication, multi-cell networks, statistical model, system level simulation, phase-frequency response
