In heterogeneous networks (HetNets), although deploying numerous small base stations
(SBSs) can effectively enhance spectral efficiency (SE), it is difficult to achieve seamless …

Integrating unmanned aerial vehicles (UAVs) as user equipment (UE) and base-stations
(BSs) into an existing LTE-Advanced heterogeneous network (HetNet) can further enhance …

Unmanned aerial vehicles (UAVs) can supplement the existing ground-based
heterogeneous cellular networks (Het-Nets), by replacing/supporting damaged …

An integrated access and backhaul (IAB) network architecture can enable flexible and fast
deployment of the next-generation cellular networks. However, mutual interference between …

Unmanned aerial vehicles (UAVs) have the capability of supplementing as well as
improvising terrestrial cellular communications as aerial base stations to improve network …

In this paper, we consider the sum rate maximization problem in a downlink unmanned
aerial vehicles (UAV) assisted heterogeneous networks (HetNets) to mitigate existing …

Unmanned aerial vehicles (UAVs) can play a key role in meeting certain demands of cellular
