摘要
可重构智能表面(Reconfigurable Intelligent Surfaces, RISs)构成了可编程电磁传播环境的关键赋能技术,近来被视为满足下一代无线网络严苛的连接性、可靠性、定位与可持续性需求的候选物理层技术。在本文中,我们首先介绍在正在进行的欧盟 Horizon 2020 RISE-6G 项目内近期设计的 RIS 赋能智能无线环境的部署场景,以及将 RIS 与现有标准化接口集成的网络架构。我们识别了多种 RIS 部署策略,并根据 RIS 硬件架构及相应能力,勾勒出在 RIS 控制与信令方面的核心架构需求。此外,借助仿真与反射阵列测量,我们引入并讨论了在 RIS 赋能无线系统背景下出现的两个新度量:RIS 带宽与影响区域。对其的广泛研究证实了在未来网络中仔细部署与规划 RIS 技术的必要性。
