论文摘要
集成的感应和通信(ISAC)正在成为解决日益增长的频谱拥塞问题并满足无处不在感应和交流需求不断增长的关键推动者。通过共享各种资源和信息,ISAC实现了更高的光谱,能源,硬件和经济效率。同时,可重构智能表面(RIS)技术被认为是一种有前途的方法,因为它有能力以能量和硬件有效的方式智能操纵无线传播环境。在本文中,我们分析了部署RIS以改善ISAC系统中的沟通和感应性能的潜力。我们首先描述了RIS的基本原理及其在传统的传播和传感系统中的应用,然后介绍ISAC和概述RIS辅助ISAC的现有探索原理,然后进行一个案例研究,以验证在ISAC系统中部署RIS的优势。最后,讨论了开放的挑战和研究方向,以刺激这一研究线,并为实际应用铺平道路。
Integrated sensing and communication (ISAC) is emerging as a key enabler to address the growing spectrum congestion problem and satisfy increasing demands for ubiquitous sensing and communication. By sharing various resources and information, ISAC achieves much higher spectral, energy, hardware, and economic efficiencies. Concurrently, reconfigurable intelligent surface (RIS) technology has been deemed as a promising approach due to its capability of intelligently manipulating the wireless propagation environment in an energy and hardware efficient manner. In this article, we analyze the potential of deploying RIS to improve communication and sensing performance in ISAC systems. We first describe the fundamentals of RIS and its applications in traditional communication and sensing systems, then introduce the principles of ISAC and overview existing explorations on RIS-assisted ISAC, followed by one case study to verify the advantages of deploying RIS in ISAC systems. Finally, open challenges and research directions are discussed to stimulate this line of research and pave the way for practical applications.
