arXiv:2610.27695v1 Announce Type: new Abstract: Reconfigurable intelligent surfaces (RISs) have emerged as one of the most promising technologies for the next-generation wireless networks, offering advantages such as cost efficiency, low power consumption, flexible deployment, and large effective aperture. Extensive studies have demonstrated the capabilities of RISs to enhance communication performance, including coverage extension, sum-rate improvement, interference suppression, security enhancement, etc. As 6G networks continue to evolve, wireless sensing is expected to play a pivotal role alongside communication. Undoubtedly, RISs possess great potential to enable seamless integration of sensing and communication by supporting both passive and active sensing paradigms. This paper explores how RISs can revolutionize wireless networks by enhancing both communication and sensing capabilities. Specifically, we highlight the fundamental principles, potential applications, and future trends of RIS-assisted integrated sensing and communication (ISAC), anticipating that RIS-enabled ISAC will become a key enabler in the upcoming 6G era.
