Abstract

the fifth-generation (5G) aims to support the 1000-fold increase in mobile data traffic, massive connectivity, user fairness, and low transmission latency. Millimeter-wave (mm-Wave) is a reliable technology with 30-300 GHz. Such bands work with Massive multiple-input-multiple-output (Massive MIMO) to enable a broad antenna array in a small space for accommodating high-degree beamforming gain. At the same time, they integrate with Non-Orthogonal Multiple Access (NOMA) to meet such requirements. On the other hand, simultaneous wireless information and power transfer (SWIPT) improves the energy efficiency of a whole system thatuses a power splitting receiver to extracts informationand harvest energy. This paper proposes incorporating the above technologies with hybrid precoding, user grouping algorithms, and power allocation methods. It is noted that this paper covers a wide range of topics.Overall we see the technique proposed here easily outperforms the other approaches as shown in simulation results.
