RIS Reflection and Placement Optimisation for Underlay D2D Communications in Cognitive Cellular Networks

Reconfigurable intelligent surface (RIS) is considered a promising technology in sixth-generation (6G) networks due to its ability to configure the phase of signals using low-cost reflecting elements. An RIS-aided device-to-device (D2D) communication system operating in underlay mode is considered i…
