Grant-free Random Access with Self-conjugating Metasurfaces
Davide Dardari, Marina Lotti, Nicolò Decarli +1
Recently, grant-free random access schemes have received significant attention in the scientific community as a solution for extremely low-latency massive communications in new ind…
Radio SLAM for 6G Systems at THz Frequencies: Design and Experimental Validation
Marina Lotti, Gianni Pasolini, Anna Guerra +3
Next-generation wireless networks will see the convergence of communication and sensing, also exploiting the availability of large bandwidths in the Terahertz (THz) spectrum and el…
Two-Timescale Joint Precoding Design and RIS Optimization for User Tracking in Near-Field MIMO Systems
Silvia Palmucci, Anna Guerra, Andrea Abrardo +1
In this paper, we propose a novel framework that aims to jointly design the reflection coefficients of multiple RISs and the precoding strategy of a single BS to optimize the self-…
Near-field Localization with Dynamic Metasurface Antennas
Qianyu Yang, Anna Guerra, Francesco Guidi +5
Sixth generation (6G) cellular communications are expected to support enhanced wireless localization capabilities. The widespread deployment of large arrays and high-frequency band…
LoS MIMO-Arrays vs. LoS MIMO-Surfaces
Marco Di Renzo, Davide Dardari, Nicolo' Decarli
The wireless research community has expressed major interest in the sub-terahertz band for enabling mobile communications in future wireless networks. The sub-terahertz band offers…
Two-Timescale Transmission Design and RIS Optimization for Integrated Localization and Communications
Fan Jiang, Andrea Abrardo, Kamran Keykhoshravi +3
Reconfigurable intelligent surfaces (RISs) have tremendous potential to boost communication performance, especially when the line-of-sight (LOS) path between the user equipment (UE…
