摘要

通信感知一体化（integrated sensing and communication，ISAC）是6G的主流趋势，将ISAC引入智能超表面（reconfigurable intelligent surface，RIS）系统，具有扩展系统覆盖范围、提升通信和感知性能、降低系统成本和功耗三大优势。在概述和分析RIS系统ISAC研究现状的基础上，提出了两种非正交ISAC方法，支持盲区用户在非正交时频资源上的通信和感知，最后探讨了 RIS 系统 ISAC 的技术挑战和未来发展。

Abstract

Integrated sensing and communication (ISAC) is the dominant trend of the sixth generation mobile communication networks (6G).The introduction of ISAC into the reconfigurable intelligent surface (RIS) system can expand the system coverage

improve both communication and sensing performances

and reduce the hardware cost as well as the power consumption of the system.On the basis of outlining and analyzing the research status of ISAC in RIS systems

two non-orthogonal ISAC methods were proposed to support concurrent communication and sensing for blind-zone users on non-orthogonal time-frequency resources.Finally

the technical challenges and future development of ISAC in RIS systems were discussed.
