“…For example, both algorithms achieved rates of more than 12 nats/sec/Hz (1 nat ≈ 1.443 bits). Similarly, authors in [45], [77] also reported the benefits of resource sharing between cellular access link with out-of-vehicle links.…”

“…The sidehaul communication also takes place over X2 interface. The OVantenna and AL-antenna are linked together using Common Communication Unit (CCU) which also controls resource and power allocation for access, backhaul, and sidehaul links [45]. It is important to mention that the architecture of moving networks is not yet standardized and a detailed discussion is presented in Section IV.…”

“…The wireless backhaul has low cost of deployment (i.e., CAPEX) and is more suitable for outdoor urban environments. Hence, majority of researchers have considered wireless backhaul for moving networks [41], [45], [72]- [78] etc. These researches discuss two competing technologies (IEEE 802.11p and cellular backhaul) to connect mobile cells to the backbone network.…”

“…The problem with these approaches is that they do not increase the spectral efficiency as the resource sharing was split in time to avoid the high levels of interference between backhaul and access link antennas.. In [45], [77], Jaffry et al demonstrated the sub-channel sharing between in-vehicle and out-of-vehicle links in the same sub-frame. The authors exploited vehicular penetration losses to enable resource sharing with minimal interference.…”

“…It is worth noting that the macro-cell base station does not always transmit backhaul signals to the mobile cells. Hence, in the absence of backhaul signals, [45] proposed algorithms to extend sub-channel sharing between in-vehicle access link and of out-of-vehicle macro-cell users' access link in [45]. The authors further used Successive Interference Cancellation (SIC) technique at the backhaul antenna to further reduce the in-band interference from spatially closer AL-antenna.…”

The unprecedented increase in the demand for mobile data, fuelled by new emerging applications and usecases such as high-definition video streaming and heightened online activities has caused massive strain on the existing cellular networks. As a solution, the fifth generation (5G) of cellular technology has been introduced to improve network performance through various innovative features such as millimeter-wave spectrum and Heterogeneous Networks (HetNet). In essence, HetNets include several small cells underlaid within macro-cell to serve densely populated regions like stadiums, shopping malls, and so on. Recently, a mobile layer of HetNet has been under consideration by the researchers and is often referred to as moving networks. Moving networks comprise of mobile cells that are primarily introduced to improve Quality of Service (QoS) for commuting users inside public transport because the QoS is deteriorated due to vehicular penetration losses and high Doppler shift. Furthermore, the users inside fast moving public transport also exert excessive load on the core network due to large group handovers. To this end, mobile cells will play a crucial role in reducing overall handover count and will help in alleviating these problems by decoupling in-vehicle users from the core network. This decoupling is achieved by introducing separate in-vehicle access link, and out-of-vehicle backhaul links with the core network. Additionally sidehaul links will connect mobile cells with their neighbors.To date, remarkable research results have been achieved by the research community in addressing challenges linked to moving networks. However, to the best of our knowledge, a discussion on moving networks and mobile cells in a holistic way is missing in the current literature. To fill the gap, in this paper, we comprehensively survey moving networks and mobile cells. We cover the technological aspects of moving cells and their applications in the futuristic applications. We also discuss the use-cases and value additions that moving networks may bring to future cellular architecture and identify the challenges associated with them. Based on the identified challenges we discuss the future research directions.

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.
