Abstract
Future 5G mobile networks are expected to support high numbers of simultaneously connected devices and to achieve high system spectrum efficiency at low power consumption. To attain these goals, device-to-device (D2D) communication is a key component. We allow any cellular user equipment to share its radio resource with multiple D2D devices and then develop the MiSo algorithm, which considers spectrum reuse and power control jointly. Simulation results confirm that compared with several algorithms, MiSo achieves highest system throughput and power efficiency with shortest run time.
