Special Issue Information

Dear Colleagues,

The global telecommunication network is the largest technological object ever created by human society. It is being constantly enhanced and improved to keep up with our needs to exchange, store and process huge, ever-growing amounts of data. Network Performance directly affects the Quality of Service (QoS) of traffic flows and the Quality of Experience (QoE) perceived by users of communication services. Technologies evolve all the time and new communication systems emerge quickly; while it takes much longer to design, deploy and operate a full-scale network, this is when quality of service deficiencies may be revealed. To cover this gap, almost in parallel with new technologies, scholars and engineers develop new and enhance existing techniques and even theories to analyze the performance of emerging communication systems.

In this Special Issue, we focus the attention of authors and readers on the problems of performance and quality of 5G wireless networks, which are already under operation, and even 6G ones, which are at the initial stage of research. We are interested in new system models, scenario cases, approaches to the analysis of performance metrics, simulation and measurement results, etc., i.e., everything that is hidden behind the title of the Special Issue.

The roll-outs of fifth-generation (5G) New Radio (NR) systems operating in the millimeter-wave (mmWave) frequency band are essential for satisfying IMT-2020 requirements set forth by ITU-R in terms of the data rate at the access interface. To overcome mmWave-specific propagation phenomena, a number of radio access network densification options have been proposed, including a conventional base station (BS) as well as integrated access and backhaul (IAB) with terrestrial and aerial IAB nodes. The aim of this paper is to qualitatively and quantitatively compare the proposed deployments using coverage, spectral efficiency and BS density as the main metrics of interest. To this end, we develop a model capturing the specifics of various deployment options. Our numerical results demonstrate that, while the implementation of terrestrial relaying nodes potentially improves coverage and spectral efficiency, aerial relays provide the highest coverage, three times that of a direct link connection, and also significantly reduce the required BS density. The main benefit is provided by the link between the BS and the aerial relay. However, gains are highly dependent on a number of elements in antenna arrays and targeted outage probability. The use of terrestrial relays can be considered a natural trade-off between coverage and the aggregate rate. Full article

Integrated Access and Backhaul (IAB) is an enabling technology for efficient 5G millimeter wave (mmWave) New Radio (NR) deployment. The key feature of IAB is multi-hop wireless backhauling, allowing utilizing relaying IAB-nodes to provide cost-efficient access network densification and alleviate the problem of blockages. One of the critical performance measures in such systems is the latency of packet delivery over the multi-hop paths. The paper aims at assessing the impact of multi-hop transmission on the end-to-end delay in an IAB radio access network, taking into account the half-duplex constraint. We build a detailed queuing theory model for latency assessment in time-division-multiplexing (TDM)-based IAB deployments and evaluate the delay due to queuing in the network nodes for several cell topologies and under different time allocation strategies between access and backhaul. The paper considers a practical Manhattan-style urban deployment, which is characteristically impaired by the blockage of buildings. The numerical results show that balancing the access and backhaul micro phases is crucial for reducing the end-to-end packet delay, at least in the uplink, while increasing the number of network hops yields a linear increase in the total packet delay for both the uplink and downlink. The numerical results were obtained via simulation using the open-source software OMNeT++. Full article
