The IEEE International Workshop on 5G Architecture will be held in New Orleans, LA, USA on March 9, 2015 in conjunction with IEEE WCNC 2015.


The goal of 5GArch workshop is to expose latest insights from industry and academia on 5G architecture design, a quickly growing topic. Indeed, over the last couple of years different trends emerged calling for a rethinking of the current 4G architecture, which does not scale to the relentless traffic demand, signaling overhead, etc. In particular, from a technology perspective, the emergence of virtualization at the core network and (partly) at the radio access network is seen as crucial going beyond 4G networks. Also the increase in small cell base station density and the number of carrier components is set to follow its course spanning both microwave and milimeterwave spectrum. The idea of separation between data and control (a.k.a. Phantom Cell-like) and between downlink and uplink due to traffic asymmetry imbalance is gaining significant grounds. In addition, the use of distributed content caching in different parts of the network (EPC/RAN/edge) is considered as one of the most disruptive paradigms in 5G from both an architectural and edge intelligence point of view. From a service perspective, the emerging importance of new services requiring a very low latency or/and a very high reliability, coupled with the prevalence of internet of things services which cannot be enabled by today’s architecture, are crucial. All these aspects mandate a clean-slate approach to tackling the increasingly complex problems.

Topics of interest include but are not limited to the following:

  • Architectural enablers for new services, e.g. low latency, high reliability, machine type communication
  • Native inclusion of small cells
  • Native inclusion of aggregation, with licensed and unlicensed spectrum
  • Native inclusion of alien systems such as Wifi
  • Smart content caching and content distribution
  • Separation between data and control
  • Separation between downlink and uplink, dual connectivity
  • Architectural enablers forD2D communications
  • multi-RAT/tier/carrier integration

The workshop accepts only novel, previously unpublished papers. All submissions should be written in English with a maximum paper length of 6 printed pages (10-point font) including figures. Please follow this link to EDAS for submission.

  • Submission deadline: 1 November 2014
  • Author Notification: 15 December 2014
  • Final Manuscript: 10 January 2015

Keynote Speakers

Keynote 1: 5G Physical Layer: Technology Opportunities and Challenges

Reinaldo. A. Valenzuela
Director, Wireless communications Research Department Bell Labs, Alcatel-Lucent
Abstract: The insatiable demand for media rich content and the increasing availability of advanced devices such as smart phones, tablets, etc., is forcing the mobile communications eco system to start in earnest to consider the next generation solutions to address these needs. Some of the options being mentioned as ingredients for such 5th Generation mobile radio systems include Small Cells, HetNets, Carrier Aggregation, Machine-to-Machine, Internet-of-Things, Relays, Device-to-Device and operation in the millimeter wave spectrum range, among others. In this talk, I will review some of the background trends driving the evolution of broadband wireless access that will impact the technology choices beyond 2020. Then, I will consider in some detail some of the most intriguing options service providers may consider.

Keynote 2: Looking Ahead to 5G; Building a virtual zero latency gigabit experience

Rapeepat Ratasuk
Nokia Solutions and Networks
Abstract: Wireless data traffic is projected to skyrocket more than 10,000 fold beyond 2020 due to increased usage of smart-phones, tablets, new wireless devices and IoT. The 5G research is just starting and the industry does not have a complete view of the key requirements of a new technology generation. In this talk, we will present an overview of 5G technology covering 3-100 GHz band with emphasis on 5G requirements, spectrum considerations, propagation and channel modeling, air-interface and multi-antenna design. We will also briefly discuss the standards and commercialization timeline of next generation wireless systems. Finally, we conclude with the vision that 5G technology will provide a scalable service experience everywhere and anytime where people and machines will enjoy virtual zero latency gigabit experience when and where it matters.

Keynote 3: Coverage and Capacity Analysis of MmWave Cellular Systems

Robert Heath
Professor in Wireless communications, The University of Texas at Austin
Abstract: Millimeter wave (mmWave) spectrum may be the solution to the spectrum gridlock in cellular systems. mmWave systems overcome potentially high pathloss by using large antenna arrays at both the transmitter and receiver, to provide enough beamforming gain to reverse, if not benefit from, the effects of the higher carrier. In this talk, we introduce the concept of mmWave cellular systems. Then we examine the system-level performance of mmWave cellular systems with a special focus on coverage and capacity. This talk presents an analysis of mmWave cellular systems using the mathematical framework of stochastic geometry, which has been used to analyze the conventional cellular and ad-hoc networks. The analysis incorporates mmWave's key differentiating factors such as the limited scattering nature of mmWave channels, and the use of RF beamforming strategies (also known as beam steering) to provide highly directional transmission with limited hardware complexity. To model mmWave signals' increased susceptibility to signal blockage (shadowing) in urban environments, an exciting new tool is leveraged known as random shape theory to model blockages due to buildings and users’ self-bodies. The results show that, in general, coverage in mmWave systems can rival or even exceed coverage in the conventional systems assuming that the link margins promised by existing mmWave system designs are in fact achieved. This comparable coverage translates into a superior average rate performance for mmWave systems as a result of the larger bandwidth available for transmission.
