D2D-Assisted UAV Resource Assignment

With the rapid development of information and communication technology, air-to-ground communication, represented by unmanned aerial vehicles (UAVs), is playing an increasingly important role. UAVs can provide wireless access to devices in the absence of ground network infrastructure. Simultaneously, in order to address the issue of network congestion, the establishment of Device-to-Device Pair (DP) communication within cellular networks has become a way to enhance wireless network capacity. In this paper, we focus on the assignment of scarce spectrum resource and terminal energy consumption, proposing an air-ground communication model and emphasizing the optimization of Energy Efficiency (EE).
