Commission C - "Sub-Nyquist Sampling for Green Radio"

Convener: Yves Louet, Sumit Darak

Radio frequency (RF) allows modulation of narrow band signals with a high carrier frequency. In some cases, signals can be sparse as they are composed of a small number of narrow band transmissions spread across a wide spectral band. However, current wireless applications put severe requirements and constraints on spectrum and energy efficiency. To meet these objectives, analog to digital converter (ADC) design and associated signal processing has received a lot of attention in the past few years. This led to sub-Nyquist sampling of wideband signals so as to minimize energy and complexity. This session aims to cover all work related to sub-Nyquist sampling. It includes ADC architectures, signal processing (including non uniform sampling but not limited to reconstruction) and applications (cognitive radio, 5G mobile communications, radio-astronomy etc).

Commission C - "Communications for the Smart Grid"

Convener: Jacques Palicot, Kostas Berberidis

The electrical grid will become a smart system. Introducing smartness is all about increasing communications between local entities in order to coordinate all the elements of the global system. Indeed, it is mandatory to refer to communications when we talk about the Smart Grid. The data volume exchanged by the different actors is such that it would be impossible to transport the data without a reliable and distributed communication system. The final communication architecture for the Smart Grid has not yet been really decided even if a particular model is often mentioned. It comprises : Home Area Network (HAN) that communicates with various smart devices such as smart meters in order to provide information to the customers. Neighborhood Area Network (NAN) that connects multiple HANs networks via HAN gateway to a single NAN gateway. NAN gateways make the links between transmission and distribution networks; Wide Area Network (WAN) that provides communication links between the NANs and utilities. The WAN makes the link between the data center or control center and the transmission network. The communication technologies will be different according to the area network HAN, NAN and WAN and researchers from the Smart Grid community argue on which technology has to be used in those networks. But a point on which they almost all agree is: instead of making huge research on creating one single technology/standard to achieve the communication in the Smart Grid, to create standards that will bring interoperability between existing technologies. From this point of view Cognitive radio could be an efficient way to transport the data without overloading the frequency spectrum and to offer this interoperability. This session will discuss the communication problem of smart grid and the different possibilities to solve this problem.

Commission C - "Enabling Technologies for Smart Cities"

Convener: Shengrong Bu, Richard Yu, Hongjian Sun

Cities are growing at an unrivalled pace. Currently about 50% of the world's population lives in an urban environment, and this number is expected to be up to 70% by 2050. This dense population creates new challenges for both people and governments. "Smarter" solutions are needed to meet the increasing strain on urban environments, and there is a great need for sustainable strategies for city development. However, the problems of the urban environment and complex and their solutions must bring together many disciplines. Advances in information and communication technology, including mobile crowdsourcing, internet of things, big data analytics tools and cloud services, have the potential to act as enabling technologies to make cities smart. These technologies can help streamline the delivery of a city's core services, including health care, transit, utilities, and environmental management. Fundamental research on the combination of these technologies and their application to the smart city must be undertaken to meet these challenges. This track aims to facilitate these research efforts and enhance international collaboration by disseminating cutting-edge research results. Participants will be able to share perspectives and novel research findings, and further identify new directions in the emerging research areas of smart cities.

Commission C - "5G Small Cell Networks"

Convener: Jie Zhang, Andres Glazunov, Xiaoli Chu

With rapidly growing usage of smart phones and tablets, mobile operators have experienced tremendous data traffic increase in the last few years. It is predicted that this trend will continue at least until 2020 with a CAGR of 60-100%. Hence, the traffic (mostly data) carried by a mobile operator's network in 2020 could be over 1000 times of that in 2010. This exponential traffic growth presents a huge challenge to the mobile industry. On top of meeting this traffic increase, operators have obligations to cut energy consumptions, which normally compromise spectrum efficiency in macrocell scenarios. Dense small cell deployment is one of the most promising ways to meet the exponential traffic growth. In this session, we will solicit contributions from both academia and industry to discuss the challenging issues arising from dense small cell deployment, including but are not limited to:

  • mmWave channel modelling for typical small cell deployment scenarios;
  • massive MIMO mmWave antennas for small cells;
  • interference management in small cell/HetNets;
  • SON for small cell networks;
  • small cell backhaul;
  • green small cell networks;
  • joint indoor-outdoor small cell deployment;
  • device-to-device communications;
  • pCell;
  • LTE-LAA/WiFi co-existence.

The session will encourage industry and academia interactions, and will be very attractive for network operators, telecom vendors and research institutions.
