To meet the ever-increasing mobile data demands, spectrum reuse via small cells and Device-to-Device (D2D) communication are envisioned to substantially enhance the Fifth-Generation (5G) cellular networks’ capacity. However, co-channel interference is a penalty for excessive and unregulated spectrum reuse, which results in overall network performance. Therefore, exploring interference-aware spectrum reuse strategies is essential to leverage the benefits of small cells and D2D communications. In this work, we aim to maximize the throughput of a UAV-assisted small cell network by proposing a socio-hypergraph coloring-based subchannel assignment technique. Our proposed technique considers the cumulative interference experienced by the User Equipments (UEs) while assigning subchannels. Additionally, we consider the strength of social ties between UEs to adjust the transmit power of cellular UEs to limit interference on D2D users. The simulation results show that our proposed technique performs the best in terms of system throughput as compared to the existing techniques.
