Radio Positioning in 6G Communication Systems

ABSTACT: Enabling sensing functionality with cellular network infrastructure is envisioned as one of the disruptive features of the sixth-generation (6G) networks. By doing so, future networks will be able to “see” the physical world through radio imaging and measuring the surrounding environment, and offer advanced location-aware services and applications. Joint design of communication and sensing in a so called Integrated Communication and Sensing (ICaS) system requires careful optimization of the available system resources between the two functions to meet their respective target requirements. In this talk, I will first motivate and present the background of ICaS systems. Thereafter I will highlight our latest research results on a 5G New Radio (NR)-based cooperative multi-monostatic sensing framework for passive target localization. Our fusion-based estimation process can mitigate the effect of multipath and increase the localization accuracy in a bandwidth limited scenario. Finally, I will conclude the talk by identifying and discussing major open challenges and future directions in designing ICaS systems.
