RIS-Assisted 6G Networks: Challenges and Tradeoffs in Control Standardization

In contrast to the significant theoretical advancements in reconfigurable intelligent surfaces (RISs), relatively few studies focus on developing realistic models and prototype-based evaluations. Most current research emphasizes characterizing RIS devices, leaving network-level studies particularly scarce, despite their critical role in understanding RIS effects on network performance and supporting standardization—especially within the context of 6G. In this paper, we identify and investigate key characteristics of RIS-assisted links as a foundation for networklevel operation. By exploring various use cases and associated challenges, we propose a control plane approach. Numerical results highlight certain limitations of RIS-assisted 6G networks from a control plane perspective.
