Device-to-Device (D2D) communication, MU-MIMO and mmWave are among the key technologies in the next generation (5G) cellular network as they can significantly improve the system performance on connectivity, spectrum efficiency and energy efficiency. In this talk, we will address how to exploit these technology advantages and tackle the key technical challenges to achieve high system performance gains. In particular, we will present three schemes based on these technologies and their related performance study in 5G/IoT settings. These three schemes include a distance based power control scheme for D2D communication underlay cellular network, beamforming and NOMA based MU-MIMO in a downlink cellular network with underlay D2D users, and relay-assisted Millimeter Wave cellular networks. The talk will present detailed 5G system model, technology background, mathematical approaches and performance results based on both analysis and simulations. Key technical insights from these studies will be provided.
