In recent years, Wireless Powered Communication Network (WPCN) has been a promising technology that can be applied to existing low-power sensor networks and the Internet of Things (IoT). Sensor nodes or IoT devices are usually battery-powered. It is possible to use naturally collectable energy such as solar and wind without using a battery, but this is not a stable supply of energy. Therefore, the idea of operating a sensor network by separately setting a base station that continuously supplies power with radio waves has been presented. ThMris paper proposes an approach for how to combine Non-Orthogonal Multiple Access (NOMA) and Time-Division Multiple Access (TDMA) among various multiple access protocols applicable to wireless powered communication networks. There are some problems using TDMA alone. If a time slot is allocated so that the sum-throughput is maximized, the fairness of nodes is not guaranteed. To cope with these shortcomings, NOMA, which is known as a method to improve fairness, is mixed. Our approach is that cells are divided into sectors so that TDMA is used among sectors while NOMA is used within sectors. In addition, optimization of the sector by sector time allocation for maximum sum-throughput can lead to residual energy in certain sectors. Therefore, a directional digital beamforming adapted to the transmission for each sector is used for efficient energy transmission. Unlike the previous user clustering, we attempt to generalize the number of nodes for NOMA from the fixed two nodes to any nodes by introducing the sector-based system model. The simulation results show that there is a trade-off between the sum-throughput and fairness because the sum-throughput increases but the fairness decreases as the number of sectors increases. As a result, we can suggest that a balanced range lies in between three and six sectors to satisfy both the sum-throughput and fairness at the same time. Finally, it is proven that our hybrid approach improves fairness significantly with the increasing number of nodes, as compared to the original TDMA only.
