Reconfigurable Intelligent Surfaces (RIS) Assisted Wireless Networks: Collaborative Regulation, Deployment Modes, and Field Testing

This article analyzes and discusses the two deployment modes of RIS-Assisted wireless networks, namely Network Controlled Mode and Standalone Mode. It presents three typical collaboration scenarios of RIS networks, including multi-RIS collaboration, multi-user access, and multi-cell coordination, and proposes collaborative regulation mechanisms for RIS. The article also establishes simulation models of these scenarios and provides numerical simulation results, as well as builds an actual field test environment to conduct preliminary field tests and verification.
