摘要:

可重构智能表面(RIS)辅助通信通过向电信运营商提供系统设计中的新自由度而作为第六代(6G)无线网络的潜在使能器之一出现。特别地,RIS授权的毫米波(mmWave)通信系统可以是提供宽带和无处不在的连接的补救措施。本文旨在通过为毫米波频率提供物理,准确,开源和广泛适用的RIS信道模型来填补公开文献中的一个重要空白。我们的模型不仅适用于各种室内和室外环境,而且通过考虑5G无线电信道条件,还包括存在RIS时无线传播的物理特性。各种部署方案提出的RIS和有用的见解提供了系统设计师从潜在的RIS用例和他们的有效定位的角度。揭示了RIS的使用对通信系统性能有很大影响或可能没有很大影响的场景。本文还介绍了开源的、功能全面的SimRIS信道模拟器。

英文摘要:

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.
