This subproject aims to integrate reconfigurable intelligent surfaces (RIS) into the network infrastructure for communication tasks, detection, localisation, and computation.
Main results of the research carried out in this sub-project:
– Design principles of an O-RAN compatible testbed.
– Data sets collected from a large set of experiments.
– An AI-based intelligent radio controller (AIRIC) to organise vRAN computing resources.
– Risk-aware decision-making framework for contextual bandit problems, considering constraints and continuous action spaces.
– Optimal design of a virtual reality network assisted by a multi-user intelligent reconfigurable surface.
– Efficiency of cache allocation mechanisms to reduce total energy consumption in O-RANs.
– CloudRIC, a system that addresses the limitations of current vRANs.
– ARES, a system capable of autonomously optimising the configuration of intelligent reconfigurable surfaces.
– RISENSE, a protocol based on transmitting amplitude modulation (AM) signals over 5G orthogonal frequency division modulation (OFDM) signals to control smart reconfigurable surfaces to minimise the load on the 5G network.
