Optimizing RIS and Power for D2D Links

This paper studies device-to-device (D2D) links enhanced by reconfigurable intelligent surfaces (RIS) in a cellular network. It presents analysis of outage probability, and proposes a framework to jointly optimize RIS placement and D2D transmitter power allocation. This is done to minimize outage probability under constraints on interference and power budgets. Results show a 44% and 20% improvement over benchmark schemes.
