“…Akdeniz et al [63] evaluate millimeter-wave systems also with a full buffer traffic model. In contrast to the previously mentioned publications, Hui and Axnas [9] and Baldemair et al [49] consider self-backhauled multi-hop networks. Routing and resource allocation for a wireless mesh is analyzed by Hui and Axnas [9], by employing a simple traffic model where a certain number of UEs are randomly selected to transmit and receive data.…”

“…It is straightforward to statically allocate each a certain share of the radio resources in advance, which is in the case of TDM a set of time slots, but this will not necessarily be optimal. On the other hand, a dynamic resource allocation [9] has to adapt to quickly changing traffic conditions. As 5G networks are expected to offer very high data rates, download/upload times are expected to be very short for most use cases.…”

“…This would enable a dense cellular network with minimal deployment cost. Furthermore, the mobile access and backhaul interfaces would use the same millimeter-wave frequencies; in other words, they would be in-band [7][8][9]. Therefore, mobile access and backhaul have to share resources and can cause each other interference, but it is not necessary to reserve an additional frequency band for backhaul only [10].…”

In recent years, mobile access networks operating at millimeter wavelengths have received a great deal of attention, as they promise previously unattainably high mobile data rates. At these frequencies, mobile access links are expected to use highly directional beamforming antennas, which are also well suited to backhaul links. Therefore, access points can efficiently act as self-backhauled relays by using the same spectrum, circuits and antennas for mobile access and backhaul links, thus forming a multi-hop in-band backhaul network. The contributions of our paper are extensive simulations to investigate user level performance in such multi-hop networks. We specifically take into account the momentary data traffic of every link in order to calculate the interference. Results quantify the detrimental effect of interference on user level performance. Furthermore, the potential benefit of using the combination of in-band and dedicated backhaul links is evaluated. Additionally, this paper investigates the user level effects of the sudden loss of a link in the backhaul mesh network, and underlines the importance of effective rerouting algorithms. The feasibility of the inband concept is demonstrated, and we can confirm that the user level experience will surpass the performance provided by previous generation mobile networks.

“…For such networks, the backhaul is a major bottleneck that can limit the throughput and deployment cost [1]. Wireless multihop backhaul is an attractive solution that can substantially reduce the deployment cost [2]. Due to the limited range of radio signals at high frequencies [3], a multihop wireless connection may need to be established between each access node (AN) and an aggregation node (AgN) where an optical wired or high speed radio link connection is available.…”

In this paper we present a novel transmission scheme for wireless multihop backhaul networks. The scheme consists of group successive relaying that efficiently exploits halfduplex relays and a coding scheme that improves quantize-mapand-forward (QMF). We derive an achievable rate region of the proposed scheme and attain a closed-form expression in the asymptotic case for several network models of interests. It is shown that the proposed scheme outperforms multihop routing, a common practical solution. Furthermore, the performance gap increases as a network becomes denser. Based on the proposed scheme, we present energy-efficient routing referred to as energyharvesting in which each node requires a lower transmission power to achieve a desired performance compared to other schemes.
