“…Such a relay enables the detected and remodulated mmWave signal to be conveyed through a waveguide to a transmit antenna mounted on an interior wall at the floor where the reference MT is located. Then, the signal is wirelessly dispatched to the reference MT 8 . Such a proposed architecture is illustrated in Fig.…”

“…Consequently, the rooftop relays form a homogeneous PPP, denoted by Φ Relays , with intensity equal to λ Blockages . 8 The proposed architecture is similar to the distributed antenna system architecture for in-building wireless communications [32]. As far as the cell association is concerned, similar to the scenario without the relays we assume that the rooftop relay of the reference building is associated with its closest BS.…”

“…Hence, the migration to mmWave bands is essential to be combined with cell densification in order to leverage the substantially higher available bandwidth [6]. Otherwise, relaying can be used to assist the BS-MT communication if high cell densification is not feasible [7][8][9].…”

In this work, we examine the feasibility of serving an indoor mobile terminal (MT) by an outdoor base station (BS) in urban millimeter-wave (mmWave) cellular networks. Towards this, we consider two scenarios: i) The signal reaches the reference MT directly by penetrating the building where it is located; ii) The communication is assisted by a relay placed on the rooftop of the building that conveys through a waveguide the desired signal to an indoor transmit antenna located at the floor where the reference MT is located. By using a stochastic-geometry based framework, we derive for both scenarios analytical expressions for the coverage and average rate, which exhibit a good match with respect to the simulations. In addition, from these expressions we gain important insights regarding the performance comparison of the two scenarios. In particular, it is analytically proved and validated by the simulations that relaying notably enhances the performance of the low-rate MTs even under substantial waveguide losses. However, for such losses the average rate in the relaying case can become worse than the case without relays.

“…Semiari et al also addressed backhaul challenges via the integration of mmWave and sub–6 GHz wireless backhauling. Eshraghi et al proposed an outage probability analysis of the mmWave relaying system in both amplify‐and‐forward and decode‐and‐forward modes. Again, backhaul issues are addressed, and the intermittent connectivity of mmWave is modeled using a line‐of‐sight (LOS) probability function.…”

As operation cost and energy consumption problems deteriorate with network densification toward 5G, traditional radio resource management and networking strategies must be upgraded. It is observed that when the access network is dealing with a large amount of user traffic, the backhaul (BH) network turns out to be the new bottleneck hindering the cellular system from further increasing its capacity and efficiency. Although wired transmission technologies, such as passive optic fiber networks, are generally available between base stations, the resulting capital expenditure and operational expenditure are prohibitive in an ultradense deployment scenario. To redesign the BH network in 5G, multihop millimeter‐wave transmission is considered as a cost‐efficient and well‐performing candidate. In this paper, we propose a low‐complexity method based on millimeter‐wave transmission to minimize the energy consumption from both the access network and the BH network through joint admission‐power‐traffic control. Concretely, a self‐organizing heuristics is created through which the access and backhaul joint energy efficiency of both the base station and the whole system is maximized under the assumption of predefined user rate requirements. Simulation results show that our proposed method achieves significant reduction (∼95%) in algorithm execution time compared with the branch‐and‐bound search at the expense of little extra energy cost (∼7%). In addition, our proposed method satisfies the quality‐of‐service requirements of user equipment in the system with a lower transmission delay in terms of hops than that of the branch‐and‐bound search. A baseline algorithm called MR‐MPF (maximum reference signal receiver power admission control with minimum power flooding) is also compared to demonstrate our algorithm's superiority in energy saving.
