The use of unmanned aerial vehicle (UAV)- based communication in millimeter-wave (mmWave) frequencies to provide on-demand radio access is a promising approach improve capacity and coverage beyond-5G (B5G) systems. There are several design aspects be addressed when optimizing for the deployment such UAV base stations. As traffic demand mobile users varies across time space, dynamic algorithms that correspondingly adjust locations essential maximize performance. In addition careful tracking...
The deployment of millimeter-wave (mmWave) 5G New Radio (NR) networks is hampered by the properties mmWave band, such as severe signal attenuation and dynamic link blockage, which together limit cell range. To provide a cost-efficient flexible solution for network densification, 3GPP has recently proposed integrated access backhaul (IAB) technology. As an alternative approach to terrestrial deployments, utilization unmanned aerial vehicles (UAVs) IAB-nodes may additional flexibility topology...
The use of drone-cells in 5G wireless systems is a topic ongoing discussions the 3GPP standardization community. A major advantage employing drones that they can dynamically and timely improve capacity coverage cellular networks. To address this challenge, efficient network planning tools targeting spontaneous rapidly changing scenarios for dynamic design need to be developed. Complementing recent studies on optimal static drone-cell positioning Poisson point process user equipment (UE)...
There is a strong interest in utilizing commercial cellular networks to support unmanned aerial vehicles (UAVs) send control commands and communicate heavy traffic. Cellular are well suited for offering reliable secure connections the UAVs as facilitating traffic management systems enhance safe operation. However, full-scale integration of that perform critical high-risk tasks, more advanced solutions required improve wireless connectivity mobile networks. In this context, integrated access...
Unmanned aerial vehicles (UAVs) are increasingly employed for numerous public and civil applications, such as goods delivery, medicine, surveillance, telecommunications. For the latter, UAVs with onboard communication equipment may help temporarily offload traffic onto neighboring cells in fifth-generation networks beyond (5G+). In this paper, we propose evaluate use of traveling over area interest to relieve congestion 5G+ systems under spontaneous fluctuations. To end, assess two...
Recently proposed by 3GPP, Integrated Access and Backhaul (IAB) technology promises to deliver a cost-efficient flexible solution for network densification in 5G/6G systems. Since IAB architecture is based on multi-hop topology advanced functionalities, such as multi-connectivity transmission multi-routing, the potential utilization of systems raises an issue efficient system design. In this paper, we develop optimization framework capable jointly selecting paths allocating radio resources...
