论文摘要
可重新配置的智能表面（RIS）辅助通信似乎是第六代（6G）无线网络的潜在推动者之一，它通过为电信运营商提供了系统设计的新自由度。特别是，RIS授权的毫米波（MMWave）通信系统可能是提供宽带和无处不在的连通性的补救措施。本文旨在通过为MMWave频率提供物理，准确，开源且广泛适用的RIS通道模型来填补开放文献的重要空白。我们的模型不仅适用于各种室内和室外环境，而且还包括通过考虑5G无线电通道条件在RISS存在下无线传播的物理特征。为RIS提供了各种部署方案，并从潜在的RIS用例及其有效定位的角度为系统设计人员提供了有用的见解。揭示了使用RIS的情况很大，或者可能不会对通信系统的性能产生重大影响。本文还介绍了开源和全面的Simris频道模拟器。
Reconfigurable intelligent surface (RIS)-assisted communication appears as one of the potential enablers for sixth generation (6G) wireless networks by providing a new degree of freedom in the system design to telecom operators. Particularly, RIS-empowered millimeter wave (mmWave) communication systems can be a remedy to provide broadband and ubiquitous connectivity. This paper aims to fill an important gap in the open literature by providing a physical, accurate, open-source, and widely applicable RIS channel model for mmWave frequencies. Our model is not only applicable in various indoor and outdoor environments but also includes the physical characteristics of wireless propagation in the presence of RISs by considering 5G radio channel conditions. Various deployment scenarios are presented for RISs and useful insights are provided for system designers from the perspective of potential RIS use-cases and their efficient positioning. The scenarios in which the use of an RIS makes a big difference or might not have a big impact on the communication system performance, are revealed. The open-source and comprehensive SimRIS Channel Simulator is also introduced in this paper.
