Introduction

In order to meet the capacity requirements of future cellular networks in the long term, it is targeted to establish an overlay of mm-wave cells on top of the current cellular network. This approach involves the two above-mentioned methods to increase network capacity promising the highest gains: network densification and spectrum extension. In contrast to current approaches, that aim for increasing the capacity by adding smaller cells operating in the same frequency band and hence run into interference limitations, no interference is induced by the mm-wave overlay. Furthermore, a huge frequency bandwidth can be exploited, globally harmonised over more than 6 GHz spectrum.

The successful adoption of mm-wave technology as a versatile wireless transmission option will be advocated by MiWEBA providing high speed access using mm-wave nano-cells on the one hand and using licence free mm-wave links for backhaul to small cells or as wireless front haul extensions in e.g. C-RAN architectures on the other hand. Once, sufficient market penetration with terminals supporting mm-wave technology is reached, direct link type device-to-device communication will enable direct user data exchange when in close vicinity.

Research Goals in MiWEBA

Millimetre-wave Radio Access Links

The MiWEBA system concept rationale is to overcome the current limitations by an integrated holistic approach using mm-wave technology. A fundamental ingredient is the separation of control and user-plane. The control plane (C-plane) will be operated at the regular cellular frequencies e.g. between 700 MHz and 2.7 GHz and the data link layers (u-plane) of the cellular network and the millimetre-wave band as a high capacity deployment overlay. In this overlay the wide coverage area of the c-plane allows to track user links and exchange information on channel state and link quality and therefore to enable seamless handover between the robust low and moderate data rate cellular band and the high data rate mm-wave band.

Wireless Backhaul and Fronthaul links

The basic difference between backhaul and front haul links is the position of the logical split in the network architecture. While the backhaul link usually transports the pure user data (e.g. IP packets) the front haul link carries data often transports already encoded and preprocessed digital signals prepared for the access link. As a consequence this leads to different requirements on the latency, robustness and bandwidth that these links have to provide.
A typical macro and small cell deployment challenge is the provisioning of cost efficient fixed line type connectivity between base band units (BBU) and remote radio units (RRU) if fiber is either not deployed or not available at certain locations, setting an urging need for wireless connections supporting carrier grade connectivity between BBU and RRU in the C-RAN architecture. More specifically, reliability, latency, synchronisation jitter, load adaptive wireless front haul capacity, daisy chaining and quasi zero installation and maintenance effort are a few out of many key requirements for such wireless links. In the context of this project we will focus on mm-wave technology to fulfil these C-RAN and HetNet specific requirements. The mm-wave wireless front- and backhaul links are required to support point-to-point (P2P) and point-to-multipoint (P2MP) topologies and to be set-up and operated in a self-organised and self-optimised manner. Furthermore the density of such mm-wave front- and backhaul links might be very high at certain locations requiring advanced link coordination schemes to satisfy carrier grade QoS.

Access Link Optimization

Though only short distances are to be bridged to the users within a mm-wave cell, suitable techniques have to be used to overcome the high path loss. A much-discussed approach is to establish highly directional adaptive links and track them by beam steering techniques. This guarantees a sufficient signal level at the receiver while reducing potential interference between neighbouring nano-cells. Consequently, the available millimetre-wave band can be used efficiently and a joint signal processing is not required. However, new challenges arise concerning the beam tracking, decentralised handover strategies (“intelligent edge”) and the medium access control (MAC).

Work packages

WP1: Scenarios, Use cases, Business Models

The first work package is of a more general technical nature. Scenarios and use cases are defined according to the project vision and serve as input to the technical work packages 2 through 5. Furthermore business models for the final phase of the project, exploitation, are formulated.

WP2: Design of front- & backhaul links

The front- and backhaul links are inner parts of the mobile radio networks that are invisible to the end user. Within this WP, a replacement for these links using mm-wave or terahertz technology and the integration into the network structure is researched.

WP3: Design of access links

The access link is the connection between the user device and the network. This work package consists of the redesign of these links with the new frequency bands.

WP4: Radio Resource Management

The introduction of the overlay nano-cells leads to a new heterogeneous network structure. The radio resource management has to be adapted to the new degree of freedom introduced with the overlay.

WP5: Propagation & Antennas

The knowledge on outdoor channels in the new frequency bands utilised by MiWEBA is nowhere near that of the well-established frequency bands. Within this work package, these channels will be thoroughly characterised and appropriate steerable high gain antennas will be developed. The channel model will also serve as input to the previous three work packages 2 through 4.

WP6: Proof of concept, Integration

The outputs of the work packages 2 to 5 will be combined within this work package to provide a proof of concept in respect to the scenarios and use models defined in the first WP.

WP7: Dissemination & Exploitation

This work package concentrates on the dissemination and exploitation of the project results.

Access : 4-3-53 Nakanoshima Kita-ku Osaka-city, Japan)

LIVE BROADCAST http://www.ustream.tv/channel/cchetnet-live

Passcode: cchetnet_workshop_live

The International Workshop on Cloud Cooperated Heterogeneous Networks organized by the ICT EU-Japan MiWEBA Steering Committee and held in conjunction with IEICE SR Technical Committee 2013 October Conference, 23 – 25 October, 2013, Osaka, Japan is now cordially inviting your participation.

We will have thirteen interesting invited talks by specialists from both academic institutes and industrial companies, following by a panel discussion on the latest research topic of Cloud Cooperated Heterogeneous Networks. Especially, we will focus on the aspect of efficient deployment of future heterogeneous networks where wideband mm-wave small cells are introduced inside the coverage of conventional micro-wave marcocell. A banquet dinner following the workshop will be organized for both the speakers and the workshop participants.

Scope

Due to explosion of smart phones and tablets, mobile data traffic increases exponentially which pushes evolution of the current cellular networks. The increasing rate of the traffic is about 2-fold per year. It indicates that at least 1,000 times system rate improvement is needed to accommodate increased traffic in 10 years. A promising approach to solving this problem is the novel cellular architecture of cloud cooperated HetNet with heterogeneous deployment of base stations connected to C-RAN for enabling cooperated transmission. Especially, tremendous capacity enhancement can be realized through introducing ultra wideband mm-wave small cells inside the coverage of conventional micro-wave cells owing to advancement of mm-wave technologies nowadays. The main objective of the workshop is to offer an opportunity for academic and industrial researchers for spreading and sharing the latest research results and discussing about the future of cloud cooperated cellular networks embedded with ultra wideband mm-wave small cells.
