AI总结:

本文从工业界视角分析可重构智能表面(RIS)商业化与标准化面临的挑战,并提供了使RIS在工业上可行的清晰路线图。

摘要:

随着第5代(5G)无线网络的标准制定和商业化以前所未有的速度完成,学术界和工业界的研究人员、工程师和高管们已将目光转向支持下一代无线网络的候选技术。可重构智能表面(RIS),有时被称为智能反射表面(IRS),已被确定为未来无线网络的潜在组件,因为它们能够利用低成本的无源设备重新配置无线信号的传播环境。这样做可以预期显著增加小区的覆盖范围以及网络的整体吞吐量。RIS不仅已成为一个极具吸引力的研究领域,还引发了多个项目以开发适当的解决方案,从而实现硬件演示和原型的搭建。与此同时,一些地区已经开始了面向标准化的技术讨论和活动。推动RIS集成到未来商业网络并取得商业成功,需要在区域级标准制定组织(SDO)和国际SDO(如第3代合作伙伴计划,3GPP)层面进行大量的标准化工作。尽管许多研究论文探讨了如何使用和优化RIS,但鲜有努力致力于分析商业化RIS的挑战以及如何对RIS进行标准化。本文旨在从工业界视角对RIS进行阐述,并提供一条使RIS在工业上可行的清晰路线图。

英文摘要:

With both the standardization and commercialization completed in an unforeseen pace for the 5th generation (5G) wireless network, researchers, engineers and executives from the academia and the industry have turned their sights on candidate technologies to support the next generation wireless networks. Reconfigurable intelligent surfaces (RIS), sometimes referred to as intelligent reflecting surfaces (IRS), have been identified to be potential components of the future wireless networks because they can reconfigure the propagation environment for wireless signals with low-cost passive devices. In doing so, the coverage of a cell can be expected to increase significantly as well as the overall throughput of the network. RIS has not only become an attractive research area but also triggered a couple of projects to develop appropriate solutions to enable the set-up of hardware demonstrations and prototypes. In parallel, technical discussions and activities towards standardization already took off in some regions. Promoting RIS to be integrated into future commercial networks and become a commercial success requires significant standardization work taken place both at regional level standards developing organizations (SDO) and international SDOs such as the 3rd Generation Partnership Project (3GPP). While many research papers study how RIS can be used and optimized, few effort is devoted to analyzing the challenges to commercialize RIS and how RIS can be standardized. This paper intends to shed some light on RIS from an industrial viewpoint and provide a clear roadmap to make RIS industrially feasible.
