“…In our paper, we qualitatively and quantitatively characterize different types of 5G mmWave NR deployment options, including (i) conventional BS-based systems, (ii) terrestrial IAB systems, and (iii) aerial IAB systems. Similarly, terrestrial coverage was studied in [19]; however, the study focused on transmission power impact to coverage, whereas we consider antenna arrays and outage probability as parameters and also give a comparison against aerial IABs. We account for specific mmWave propagation conditions, including blockage by small dynamic and large static objects.…”

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.

“…The user equipment (UE) that is outside the coverage of the DgNB may associate with the nearest available IAB node, thus benefiting from coverage extension provided by the emerging IAB architecture [4]. The performance of an IAB network with respect to the coverage extension has been extensively investigated in the literature [5]. Resource partitioning is addressed in [6] while topology formation problem is solved in [7], [8].…”

The recently proposed NR-ready integrated access and backhaul (IAB) architecture promises to bring a costefficient deployment solution for both coverage extension and capacity boosting in future 5G/5G+ systems. While its impact on the coverage extension was thoughtfully addressed in the literature, the effect of advanced functionalities such as multi-hop, multi-connectivity, and multi-beam operations on the throughput remains unclear. We review and characterize the system-level impact of these capabilities on the performance of self-backhauled IAB systems operating in half-duplex mode and utilizing millimeter-wave (mmWave) technology across both access and backhaul. Our results indicate that the throughput gain of multi-hopping and multi-beaming is significant even without multi-connectivity operation. Another important learning is that in all-mmWave systems with link blockage, multi-connectivity with link switching allows achieving self-load balancing. Finally, we outline future research directions.
