摘　　要：IS能以节能和高效的方式构建良好无线电传播环境,被认为是6G关键技术之一。ISAC通过共享各种资源和信息,正成为解决日益严重的频谱拥塞问题并满足日益增长的无处不在的传感和通信需求的关键技术。首先描述了IS的基本原理及其在传统通信和传感系统中的应用,然后介绍了ISAC原理并概述了IS辅助ISAC的现有工作,最后对IS辅助ISAC的未来研究方向进行了展望,以进一步扩展这一研究方向并为实际应用铺平道路。Intelligent surface (IS) has been deemed as one of the key technologies for 6G due to its capability of intelligently manipulatingthe wireless propagation environment in an energy-efficient and highly effective manner. By sharing various resources andinformation, integrated sensing and communication (ISAC) is emerging as a key technology to address the growing spectrumcongestion problem and satisfy the increasing demands for ubiquitous sensing and communication. This paper providesthe basic principle of IS and its applications in conventional communication and sensing systems. Furthermore, this paperintroduces the ISAC principle and outlines the existing work of IS-aided ISAC. Finally, the future research directions of ISassistedISAC are prospected to further expand this research field and pave the way for practical applications.
