RIS Dynamic Control Strategies in Smart EM Environments for 6G Networks

The concept of Reconfigurable Intelligent Surfaces (RISs) is attracting a considerable academic and industrial interest in view of their potential adoption in 6G networks. Nevertheless, several important challenges still need to be addressed from the technological and methodological viewpoint to enable the deployment and effective exploitation of RISs. This is specifically relevant concerning the surface dynamic control algorithms to be implemented for a successful integration of RISs in existing wireless environments. In this framework, the objective of this work is to illustrate the recent advances and emerging solution strategies for RIS configuration and adaptation in next generation networks.
