The next 6G cellular networks will be a rendez-vous between localization, sensing, and communication. Indeed, through their codesign, new applications, such as cross/augmented reality, radio holography, and autonomous vehicle navigation, will be enabled at an unprecedented accuracy and reliability. Towards this vision, large intelligent surfaces (LISs) have already been identified as a potential technology thanks to the possibility to shape the electromagnetic environment intelligently, enhancing ambient awareness. For example, the high mobility of users (e.g., drones and vehicles) might be assisted by LIS for easing the handover failures or supporting autonomous navigation and localization-based applications. Nevertheless, LISs are expected to be beneficial not only in terms of achievable spatial accuracy or system scalability but also continuity, e.g., for overcoming most pathological non-line-of-sight conditions. They shall indeed enable a timely/localized adaptation to various location-based application requirements and on-demand service provision in complex multi-user multi-operator contexts, e.g., in terms of both localization and sensing accuracy and/or addressed/preferred spatial dimensions. All these capabilities raise open research questions related to, e.g., multi-objective multi-constraint optimization, localization-oriented RIS control and cooperative mechanisms, and suitable estimation algorithms at both single-link and multi-link levels. In addition, localization and sensing will coexist with communication in the same radio spectrum by sharing the same hardware. Hence, their codesign will be essential, as well as the capability to minimize overhead, power consumption and re-deployment cost, i.e., in comparison with ad-hoc conventional localization and sensing approaches. In the next joint EuCNC & 6G summit, this special session aims to host innovative scientific contributions on these topics, capable of orienting the discussion on the latest localization and sensing solutions.
