🧠 What is it about?
In this work, we propose SORIS, a novel self-organized reconfigurable intelligent surface (RIS) hardware architecture that enables autonomous channel estimation and configuration without requiring dedicated links to the transmitter or receiver. By combining:
đź«´ a microcontroller-enabled RIS architecture,
đź«´ low-latency channel estimation using a small subset of transmitting RIS elements, and
🫴 a low-complexity machine learning framework that exploits spatial channel correlation,
SORIS can efficiently acquire channel state information and dynamically reconfigure itself to assist wireless communications. We also provide a detailed complexity, wiring density, and control signaling analysis, and validate the feasibility and performance of the proposed design through Monte Carlo simulations.

🌱 This work contributes to the development of energy-efficient, scalable, and intelligent RIS-assisted wireless systems, aligning with the vision of green and sustainable communications.

Abstract: Holographic metasurfaces have emerged as a pivotal technology in advancing sixth-generation (6G) networks, facilitating smart environments that manipulate electromagnetic (EM) waves to enhance signal coverage and robustness. High data rate communication and high-resolution sensing are essential for 6G wireless networks. Yet, developing a unified hardware system that integrates communication and sensing (ISAC) at these standards remains a formidable challenge. A critical issue is the EM interference between the sensing and communication signals, which can undermine both the effectiveness and reliability of the system. This paper introduces a novel architectural approach for holographic metasurfaces which operate across mmWave for communication and integrate THz graphene antennas for sensing, crucial for the deployment of future 6G networks. We outline potential applications of this integrated THz-mmWave system and discuss various challenges and considerations essential for its effective implementation and commercial viability, aiming to ensure robust, efficient, and scalable network performance.
