Integrating Reconfigurable Intelligent Surfaces (RISs) into Indoor D-MIMO Networks for 6G
Paper in proceeding, 2024
We concentrate on indoor use cases with large user equipment (UE) populations where the service coverage is low due to the high obstacle density. To that end, we propose dynamic user-centric AP clustering and RIS placement techniques adapted for serving multi-user indoor systems. Here, we use an alternating optimization method as a sub-optimal solution for RIS phase-shift configuration, keeping the computation complexity low. We show that the integration of RISs in D-MIMO systems is an attractive approach to enhance energy efficiency and provide the scalability required in 5G and beyond (6G).
