摘要:

基于智能超表面(Reconfigurable Intelligent Surface,RIS)技术的无源工作特点,分析了RIS技术在多小区组网的实际环境中的性能影响。根据RIS技术的幅频和相频响应特性,提出了RIS反射信号的统计建模方法,为不同频率的电磁信号的RIS反射行为提供了统一的建模方法。另外,对多小区环境下的RIS辅助通信系统的干扰情况进行了系统仿真评估,并且对RIS辅助通信的组网部署要求做了分析和展望。

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
