Replacing base stations with unmanned aerial vehicles (UAVs) to serve the communication
of ground users has attracted a lot of attention recently. In this paper, we study the joint …

We consider multiple unmanned aerial vehicles (UAVs) serving a density of ground
terminals (GTs) as mobile base stations. The objective is to minimize the outage probability …

Unmanned aerial vehicles (UAVs) can be deployed as flying base stations (BSs) to leverage
the strength of line-of-sight connections and effectively support the coverage and throughput …

Cellular networks assisted by flexibly placed high-maneuverability unmanned aerial
vehicles (UAVs) have attracted virtual interests recently. In this paper, the utility maximization …

In this paper, we mainly studied the joint resource allocation and UAV trajectory optimization
for maximizing the total energy efficiency in UAV-based non-orthogonal multiple access …

Unmanned aerial vehicles (UAVs) employed as airborne base stations (BSs) are considered
the essential components in future sixth-generation wireless networks due to their mobility …

This work considers the orthogonal frequency division multiple access (OFDMA) technology
that enables multiple unmanned aerial vehicles (multi-UAV) communication systems to …

Recently, Unmanned Aerial Vehicles (UAVs) have attracted much attention due to their
flexibility and low cost. However, there are limitations for multiple UAVs such as limited …

In this paper, we consider a unmanned aerial vehicle (UAV)-enabled multiple-input single-
output (MISO) non-orthogonal multiple access (NOMA) system for a smart city environment …

In this paper, we study a joint placement, resource allocation, and user association problem
for UAV-assisted wireless networks with constrained backhaul links, where multiple UAV …
