摘要: Drone-mounted base stations (DBSs) are promising solutions to provide ubiquitous connections users and support many applications in the fifth generation of mobile networks while full duplex communications has potential improve spectrum efficiency. In this paper, we have investigated backhaul-aware uplink a full-duplex DBS-aided HetNet (BUD) problem with objective maximize total throughput network, is decomposed into two sub-problems: DBS Placement (including vertical position horizontal position) joint UE association, power bandwidth assignment (Joint-UPB) problem. Since BUD NP- hard, propose approximation algorithms solve sub-problems another, named AA-BUD algorithm, guaranteed performance. The performance AA- algorithm been demonstrated via extensive simulations, results show that superior benchmark algorithms.
