Reconfigurable Intelligent Surface Empowered Simultaneous Communication, Localization, and Mapping for Vertical Applications

As 6G communication continues to advance rapidly, it is opening up new frontiers in diverse domains such as smart cities, autonomous transportation, and industrial automation. A key enabler of these advancements is the ability to perform simultaneous communication, localization, and mapping (SCLAM) tasks. Reconfigurable intelligent surfaces (RIS) have emerged as a transformative technology to enhance communication, localization, and mapping capabilities, thereby improving system efficiency and reliability. However, the full potential of RIS in enabling these simultaneous capabilities has yet to be thoroughly explored. This article proposes innovative approaches to address real-world challenges across vertical industries, including smart cities, autonomous vehicles, and industrial automation, by integrating RIS with SCLAM systems. We discuss the anticipated benefits and technical challenges of this integration, particularly the tradeoffs between communication efficiency and the Cramér-Rao bound (CRB) for parameter estimation. Additionally, we highlight the crucial role of artificial intelligence (AI) and machine learning in achieving these goals and offer clear directions for future research in RIS-powered SCLAM systems.
