Abstract
In this work, we consider a UAV-assisted cell in a single user scenario. We consider the Quality of Experience (QoE) performance metric calculating it as a function of the packet loss ratio. In order to acquire this metric, a radio-channel emulation system was developed and tested under different conditions. The system consists of two independent blocks, separately emulating connections between the User Equipment (UE) and unmanned aerial vehicle (UAV) and between the UAV and Base station (BS). In order to estimate scenario usage constraints, an analytical model was developed. The results show that, in the described scenario, cell coverage can be enhanced with minimal impact on QoE.
Highlights
5th generation (5G) networks are standardized and deeply researched, which allows network operators to fully implement them in their architectures
We considered that the transmitted traffic uses an iLBC voice codec, and, in order to properly collect the data from the emulator, the Base station (BS) sent a constant stream of data to the User Equipment (UE)
In view of the fact that we consider a single user scenario, the optimal location of the unmanned aerial vehicle (UAV) relative to the user is strictly above him. In this case, when the user moves along the network border, it should lead to losses and, a decrease in bandwidth and QoS/Quality of Experience (QoE), which is evaluated after the emulation is carried out
Summary
5th generation (5G) networks are standardized and deeply researched, which allows network operators to fully implement them in their architectures. A number of new communication scenarios are predicted, which include holographic calls, e-medicine, flying networks, and Internet of skills [4] This in turn imposes ambitious requirements for new networks. It is assumed that a level of reliability comparable to wired networks will be provided To achieve such a performance, especially in emergency situations or in cases when the coverage of the terrestrial BSs is limited due to terrain conditions, the development of non-terrestrial networks (NTNs) is being considered. The implementation of HAPs and satellites as network elements allows for a larger coverage area, especially in difficult terrain conditions. They present a number of significant disadvantages, such as high transmission delay, low bandwidth and high deployment complexity. The experimental results show that our proposed model allows us to enhance the cell coverage while still maintaining the required QoE levels
