The increasing stress on mobile radio access performance in a context of declining revenues for operators is requiring the evolution of transport networks (backhaul and fronthaul), which currently work decoupled. The heterogeneity of the nodes and transmission technologies inter-connecting the fronthaul and backhaul segments makes the network quite complex, costly and inefficient to manage flex...

Recent work has shown that multi-cell co-operations in cellular networks, enabling distributed antenna systems and joint transmission or joint detection across cell boundaries, can significantly increase system capacity and user fairness. Most publications in this field assume that an infinite amount of information can be exchanged between the co-operating base stations, neglecting the main dow...

Multicell processing in the form of joint encoding for the downlink of a cellular system is studied under the assumption that the base stations (BSs) are connected to a central processor (CP) via finitecapacity links (finite-capacity backhaul). To obtain analytical insight into the impact of finite-capacity backhaul on the downlink throughput, the investigation focuses on a simple linear cellul...

Sparse Beamforming Design for Network MIMO System with Limited Backhaul Binbin Dai Master of Applied Science Graduate Department of Electrical and Computer Engineering University of Toronto 2014 This thesis considers a downlink multicell cooperation model in which the basestations (BSs) are connected to a central processor via rate-limited backhaul links and each scheduled user is cooperatively...

The paper discusses a DVB/IP backhaul networking environment that enables users to access triple-play IP services at a guaranteed end-to-end QoS level. Utilising the DVB-T stream in a regenerative configuration, it presents the formation of a QoS aware backhaul that interconnects intermediate distribution nodes and service/content providers (e.g. ISPs, IPTV multicasters, etc.), for enabling alw...

In this paper, we propose two secure virtual private network architectures for the long-term evolution backhaul network. They are layer 3 Internet protocol (IP) security virtual private network architectures based on Internet key exchange version 2 mobility and multihoming protocol and host identity protocol. Both architectures satisfy a complete set of 3GPP backhaul security requirements such ...

The heterogeneous deployment of high-power macro cells and low-power nodes (LPNs) is now widely acknowledged as an essential requirement towards meeting the continued demand for mobile data capacity. The selection of the optimum backhaul solution for the LPNs obliges operators to consider not only the capacity of the backhaul but also other key factors so as to fully leverage the benefits provi...

Operators, struggling to continuously add capacity and upgrade their architecture to keep up with data traffic increase, are turning their attention to denser deployments that improve spectral efficiency. Denser deployments make the problem of user association challenging, and much work has been devoted to finding algorithms that strike a tradeoff between user quality of service (QoS), and netw...

This white paper analyzes the requirements for mobile wireless backhaul. In particular, it focuses on the backhaul technology required for deploying 3G/4G small cells, which have their own specif ic characteristics and requirements. The technology has matured to the point where E-band radios, in conjunction with Carrier Ethernet networking, can support the backhaul needs accompanying deployment...

Executive summary Backhaul is a crucial enabler for mobile operators deploying new high-capacity technologies like Long Term Evolution (LTE), as they look for a solution that meets their performance requirements and minimizes costs – in particular opex, the largest contributor to backhaul costs. Backhaul prominence will rise further with the deployment of small cells, and with the associated in...
