Presentation 1 – Dr. Sergey Andreev
Title: Future of Ultra-Dense Networks Beyond 5G: Harnessing Heterogeneous Moving Cells

For past 40 years, cellular industry has been relying on static radio access deployments with gross over-provisioning. However, to meet the exponentially growing volumes of irregular data, the very notion of a cell will have to be rethought to allow them be (re-)configured on-demand and in automated manner. We advocate for a novel vision of moving networks to match dynamic user demand with network access supply in the beyond-5G heterogeneous cellular systems. The resulting adaptive and flexible network infrastructures will leverage more intelligent devices, such as connected cars and drones, by employing appropriate user incentivization mechanisms. This talk is a concise recollection of the corresponding research activities by the W.I.N.T.E.R. Group in Tampere, Finland to benefit from moving access networks in different contexts. These vary from opportunistic employment of mobile relays for small data delivery to tighter engagement of moving cells on a par with conventional (static) cellular access infrastructure, with a specific emphasis on communication challenges in extremely high frequencies.

Dr. Sergey Andreev is Senior Research Scientist at Tampere University of Technology (Finland), where he is coordinating W.I.N.T.E.R. Group (http://winter-group.net/) focusing on 5G and IoT centric research. He has (co-)authored over 150 papers, several patents, and a number of IEEE and 3GPP standardization contributions in the areas of multi-radio heterogeneous networking, cooperative and proximate communications, energy efficiency, and machine-to-machine applications. This innovation activity has been well covered in media on both national and international levels. Sergey has been reviewer for numerous visible conferences and top-level international journals; he was named Exemplary Reviewer by IEEE Communications Letters in 2013. He has also been invited expert at a number of workshops, held many guest lectures at industry and academia worldwide, as well as acted as a keynote speaker. Previously, he has been recipient of highly competitive personal research grant by the Academy of Finland (9% success rate), as well as several other prestigious scholarships and awards.

Presentation 2 – Vitaly Petrov
Title: On the Synergy of Communications and Radar in V2V Scenarios

Joint vehicular radar and communications systems operating in the millimeter and low terahertz band have been recently suggested to simultaneously enable high data-rate vehicle-to-vehicle communications and high-resolution radars in future vehicular networks. However, massive deployment of such systems may potentially lead to significant interference, affecting the reliability of both the radar and the communications modules. To address this problem we propose to combine the radar and telecom modules, such that the strength of one regime will assist in the other’s weakness. Particularly, the CSMA-based channel access provided by the telecom module protects the radar sequences from the co-channel interference. Meanwhile, the proposed radar-aided channel assessment enables CSMA for the data transmissions and minimizes the deafness problem. Using a combination of measurement- and simulation-based methods we illustrate that the proposed concept can potentially bring notable performance gains over the existing solutions.

Vitaly Petrov received the M.Sc. degree in information systems security from the Saint Petersburg State University of Aerospace Instrumentation, Saint Petersburg, Russia, in 2011, and the M.Sc. degree in communications engineering from the Tampere University of Technology, Tampere, Finland, in 2014, where he is currently pursuing the Ph.D. degree, where he is involved in enabling terahertz band communications for beyond 5G wireless networks. He was a Visiting Scholar with Georgia Institute of Technology, Atlanta, USA, in 2014, and a Strategic Intern with Nokia Research Center, Helsinki, Finland, in 2012. He has been the recipient of Best Student Paper Award at IEEE VTC-Fall’15 and Best Student Poster Award at IEEE WCNC’17. His current research interests include the Internet-of-Things, terahertz band communications, nanonetworks, cryptology, and network security.
