Recently, a mmWave-based access and backhaul integration HetNetsarchitecture (mABHetNets) has been envisioned to provide the high link capacity in both access and backhaul links. In mABHetNets, the access link and the backhaul link will share the same mm-wave spectral resources to serve cellular users as well as to maintain the backhaul capacity of the SBSs. However, a large spectrum bandwidth are occupied by the backhaul link to maintain the backhaul link capacity. Up to 50\% mmWave spectrum…

Throughput Analysis in Cache-enabled Millimeter Wave HetNets with Access and Backhaul Integration

An analytical framework is developed to characterize cache-enabled mABHetNets and the signal-to-interference-plus-noise ratio (SINR) distributions in line-of-sight (LoS) and non-line- of- Sight (NLoS), and the average potential throughput (APT) is derived.

Bandwidth Partitioning and Downlink Analysis in Millimeter Wave Integrated Access and Backhaul for 5G

An analytical framework for IAB-enabled cellular network is developed using which its downlink rate coverage probability is accurately characterized and shows that depending on the choice of the partition strategy, there exists an optimal split of access and backhaul BW for which the rate coverage is maximized.

Point-to-multipoint in-band mmwave backhaul for 5G networks

An analysis is presented to persuade the readers of the feasibility of in-band wireless backhaul, realistic deployment and system assumptions are discussed, and a scheduling scheme for inter- BS communications is presented that can be used as a baseline for further improvement.

Dynamic resource allocation in mmWave unified access and backhaul network

Three dynamic resource allocation algorithms are proposed in this paper, which investigate maximization of network capacity and the fairness among stations, respectively and can well achieve a trade off between capacity and fairness guarantee.

Tractable Model for Rate in Self-Backhauled Millimeter Wave Cellular Networks

A general and tractable mmWave cellular model capturing these key trends and characterize the associated rate distribution is proposed and shows that, in sharp contrast to the interference-limited nature of UHF cellular networks, the spectral efficiency of mmWave networks also increases with the BS density, particularly at the cell edge.

On the Feasibility of Sharing Spectrum Licenses in mmWave Cellular Systems

The theoretical feasibility of spectrum license sharing among mmWave cellular operators is established and it is shown that sharing spectrum licenses increases the per-user rate when antennas have narrow beams and is also favored when there is a low density of users.

Millimeter Wave Beamforming for Wireless Backhaul and Access in Small Cell Networks

This paper proposes the use of outdoor millimeter wave communications for backhaul networking between cells and mobile access within a cell, and proposes an efficient beam alignment technique using adaptive subspace sampling and hierarchical beam codebooks.

Millimeter-wave access and backhauling: the solution to the exponential data traffic increase in 5G mobile communications systems?

This article overviews the technologies that will pave the way for a novel cellular architecture that integrates high-data-rate access and backhaul networks based on millimeter-wave frequencies (57-66, 71-76, and 81-86 GHz), and evaluates the feasibility of short- and medium-distance links at these frequencies.

Proactive Caching Strategies in Heterogeneous Networks With Device-to-Device Communications

A proactive caching policy is proposed to exploit all communication opportunities and reduce congestion on the backhaul link, with the goal of minimizing the system cost, e.g., in terms of energy or bandwidth wastage.

Energy Efficiency of Downlink Networks With Caching at Base Stations

It is shown that caching at the BSs can improve the network EE when power efficient cache hardware is used and the caching EE gain is large when the backhaul capacity is stringent, interference level is low, content popularity is skewed, and when caching at pico BSs instead of macro BSs.

A general framework to evaluate the coverage and rate performance in mmWave cellular networks is proposed, and the results show that dense mmWave networks can achieve comparable coverage and much higher data rates than conventional UHF cellular systems, despite the presence of blockages.
