This study analyzes the performance of 3rd Generation Partnership Project (3GPP)-inspired multi-cell wideband single-hop backhaul millimeter-wave-in-band-full-duplex (IBFD)-integrated access and backhaul (IAB) networks using stochastic geometry. We modeled the wired-connected Next Generation NodeBs (gNBs) as the Matérn hard-core point process (MHCPP) to meet real-world deployment requirements and reduce the cost caused by wired connections in the network. We first derive association probabilities that reflect the likelihood that typical user-equipment is served by a gNB or an IAB-node based on the maximum long-term averaged biased-received-desired-signal power criteria. Furthermore, by leveraging the composite Gamma-Lognormal distribution, we derived the closed-form signal to interference plus noise ratio coverage, capacity with outage, and ergodic capacity of the network. To avoid underestimating the noise, we consider the sidelobe gain on the inter-cell interference links and analog-to-digital converter quantization noise. Compared with half-duplex transmission, the numerical results show an enhanced capacity with outage and ergodic capacity provided by the IBFD under successful self-interference cancellation. We also study how the power bias and density ratio of the IAB-node to gNB and the hard-core distance can affect system performance.INDEX TERMS Millimeter-wave, integrated access and backhaul, in-band-full-duplex, Matérn hard-core point process, stochastic geometry.

“…However, dealing with self-interference (SI), which can be more than 100 dB higher than the desired signal, is the biggest challenge in realizing IBFD transmission. Fortunately, a combination of antenna [9], analog [8], [10], and digital [11] SI cancellation (SIC) can achieve satisfactory performance in mmWave IBFD networks.…”

Deploying access and backhaul as wireless links, a.k.a. integrated access and backhaul (IAB), is envisioned as a viable approach to enable flexible and dense networks. Even further, mobile IAB (mIAB) is a candidate solution to enhance the connectivity of multiple user equipment (UE) moving together. In this context, different of other works from the literature, the present work overviews the basis for the deployment of mIAB by presenting: 1) the current status of IAB standardization in the fifth generation (5G) new radio (NR); 2) a new taxonomy for state-of-the-art works regarding fixed IAB and mIAB; 3) an extensive performance analysis of mIAB based on simulation results; and 4) open challenges and potential future prospects of mIAB. Specifically, the proposed taxonomy classifies IAB works according to different perspectives and categorizes mIAB works according to the type of mobile node. For each type of mobile node, the main studied topics are presented. Regarding the performance evaluation, we consider an urban macro scenario where mIAB nodes are deployed in buses in order to improve the passengers' connection. The results show that, compared to other network architectures, the deployment of mIAB nodes remarkably improves the passengers' throughput and latency in both downlink and uplink.
