Wireless communication using unmanned aerial ve-hicles (UAVs), such as drones, is expected to be a promisingsolution for improving spectral efficiency in 5G wireless networks. Moreover, full-duplex (FD) has been in the spotlight as a keytechnology for improving network performance. In this work,we design an energy-efficient medium access control (MAC)protocol for a UAV base-station (UAV–BS) aided FD wirelesscommunication network and demonstrate a comprehensive ana-lytical model considering the FD pair probability. In the proposedFD MAC protocol, the FD UAV-BS focuses on energy efficiencywhen establishing the FD pair. Throughput is also enhanced bytransmitting downlink data without decreasing the uplink datarate. We consider the FD pair probability to improve the accuracyof the analytical model. Although the FD pair probability isan important parameter for performance analysis, it has rarelybeen addressed in most previous works. We analyze FD pairprobability according to the altitude of the FD UAV-BS and thenode transmission power. The analytical model can reflect anactual network better than prior works by considering the FDpair probability. Through extensive simulations using MATLABand the Riverbed Modeler, we verified the superiority of theproposed FD MAC protocol and the accuracy of the analyticalmodel.
