RIS Control through the Lens of Stochastic Network Calculus: An O-RAN Framework for Delay-Sensitive 6G Applications
This paper proposes DARIO, an O-RAN-compliant framework that leverages a novel Stochastic Network Calculus model to dynamically assign Reconfigurable Intelligent Surfaces (RIS) to users, achieving significant uplink delay reductions for heterogeneous 6G applications by solving a near-optimal nonlinear integer program with low computational overhead.
