IEEE 6th Int. Workshop on Heterogeneous and Small Cell Networks (HetSNets)


IEEE 6th Int. Workshop on 
Heterogeneous and Small Cell Networks (HetSNets) 
in conjunction with IEEE Globecom December 8-12,
2014, Austin, TX, USA

In recent years, with the advent of more easy-to-use and powerful mobile user equipment (UEs) such as smartphones and tablets, and with the development of more appealing Internet applications, mobile data traffic has been increasing in an exponential manner. This trend is expected to continue during the next decade. In this context, heterogeneous and small cell networks (HetSNets), which are characterized by a large number of network nodes with different transmit power levels and radio frequency coverage areas, including macrocells, remote radio heads, microcells, picocells, femtocells and relay nodes, have attracted much momentum in the wireless industry and research community. They have also gained the attention of standards bodies such as the 3rd Generation Partnership Project (3GPP), overseeing the development of the LTE/LTE-Advanced standards, and the Institute of Electrical and Electronics Engineers (IEEE), overseeing the development of Mobile Worldwide Interoperability for Microwave Access (WiMAX). The impending worldwide deployments of HetSNets bring about not only opportunities but also challenges. Despite many accomplishments in HetSNets development and deployment in the last few years, many technical challenges to efficient rollouts of HetSNets remain. Among these are the co-existence and inter-working of mixed-type neighbouring and/or overlapping cells, inter-cell interference and mobility management, front-haul and backhaul provisioning, energy saving issues, self-organization, and capacity enhancements through multi-flow technologies and coordinated multiple input multiple output (MIMO) operations. These challenges need to be addressed in order for HetSNets to deliver on their promise. This calls for a thorough reappraisal of contemporary wireless network technologies, such as network architecture, protocol designs, spectrum allocation strategies, radio access management mechanisms, etc. In order to do so, those in the wireless industry, academia and even end-users need to better understand the technical details and the full potential of HetSNets.

This workshop, which is a new edition of a successful series of workshops, i.e., IEEE Globecom 2010 Intl. Workshop on Femtocell Networks, IEEE ICC 2011 Intl. Workshop on Heterogeneous Networks, IEEE Globecom 2011 Intl. Workshop on Femtocell Networks, IEEE Globecom 2012 Intl. Workshop on Heterogeneous and Small Cell Networks and IEEE Globecom 2013 Intl. Workshop on Heterogeneous and Small Cell Networks will bring together academic and industrial researchers to identify and discuss technical challenges and recent results related to HetNets. Topics of interest include, but are not limited to the following:

General topics:
  • New front- and back-haul architectures to facilitate HetSNets operations (cloud radio access network (RAN), user and control plane split, multi-flow, etc.)
  • Self-organizing HetSNets and issues in self-configuration, self-optimization and self-healing
  • Radio resource management (RRM) techniques for HetSNets (network synchronization, cell range expansion, loading balancing, dynamic TDD transmissions, etc.)
  • Improved mobility management in HetSNets and small-cell discovery mechanisms
  • Concepts for energy efficiency enhancements in HetSNets and dormant mode operation of small cells
Topics for co-channel deployment:
  • Inter-cell interference coordination (ICIC) in HetSNets (cell clustering, cell on/off techniques, carrier based ICIC, time based ICIC, power based ICIC, etc.)
  • Coordinated multi-point transmission (CoMP) techniques in HetSNets (coordinated beamforming, network MIMO, etc.)
  • Advanced receivers and interference cancellation in HetSNets
Topics for non-co-channel deployment:
  • Use of higher frequency bands, radio propagation models and measurement campaigns for small cell networks
  • Inter-node carrier aggregation and dual connectivity in HetSNets
  • Semi-static or dynamic switch between the macrocell and small cell tiers at UEs
  • Inter-working among various radio access technologies (WiFi offloading, etc.)
The workshop accepts only novel, previously unpublished papers. Prospective authors are encouraged to submit a standard IEEE conference style paper to this workshop through the EDAS submission system. (If any problem during submission is encountered, please contact the workshop chair). All submissions should be written in English with a maximum paper length of six (6) printed pages (minimum 10-point font) including figures, without incurring additional page charges. One (1) additional page is allowed with a charge of USD100, if accepted. Accepted papers must be presented at the workshop. The presenter must register for the workshop before the deadline for author registration. Failure to register before the deadline will result in automatic withdrawal of the paper from the workshop proceedings and the program. All papers selected for publication will be included in the IEEE Globecom proceedings and IEEE digital library.
