Analysis of UAV-based RF Energy Harvesting Wireless Communication Network

This paper investigates a novel UAV-based wireless communication system combined with energy harvesting and NOMA. All UAVs are served as dynamic small base stations and connect with the main base station in a given area. The unit time slot is split into two phases: the downlink (DL) phase for energy harvesting and the uplink phase for data transmission (uplink). In other words, users (UEs) will first gather energy from all UAVs and main base station transmissions before using that energy to provide uplink information transmission. To address the problems, this paper considers both inter-cell and intra-cell interference in the throughput calculation. The UVA-based system solved the inter-cell interference, which plays an important role in the performance of total system throughput in previous work. The simulations in this paper match the numerical analysis results and show that there exists an optimal
$T$
to achieve the maximum throughput. In addition, it also shows that the system throughput increases significantly based on our new system model.
