“…The interference avoidance was obtained due to the adopted TDD scheme (Table 3), which did not allow transmissions in the access links of mIAB nodes when IAB donors were operating in DL in their access links. The topic of exploiting a TDD scheme for interference handling in mIAB networks is addressed in [130].…”

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.

“…For example, one can perform power control in the mIAB nodes access links in order to reduce/avoid interfering with nearby UEs connected to the IAB donor. Another option is to insert slots of silence on the TDD frame pattern, as investigated in [130].…”
