This talk will discuss some relevant networking issues for 5G mmWave cellular systems. First, we will give an extensive discussion on the potential benefits and technical challenges of spectrum sharing in a mmWave context. We will show that from this points of view this scenario is much more promising than traditional cellular systems in sub-6 GHz bands. We will also discuss the role of coordination between different operators for the purpose of managing the inter- and intra-system interference, which is shown to be the ultimate limiting factor in spectrum sharing. Second, we will discuss how directionality makes it more difficult to implement and operate network management functionalities, with specific reference to Initial Access and Cell Search, where the energy/latency/detection tradeoff is of particular interest. Finally, we will briefly describe our full-stack 5G mmWave cellular simulator, which includes the whole protocol suite as well as detailed mmWave channel models, and present some examples of system-level results it can provide.
Michele Zorzi received his Laurea and Ph.D. degrees in electrical engineering from the University of Padova in 1990 and 1994, respectively. During academic year 1992/1993 he was on leave at the University of California San Diego (UCSD). After being affiliated with the Dipartimento di Elettronica e Informazione, Politecnico di Milano, Italy, the Center for Wireless Communications at UCSD, and the University of Ferrara, in November 2003 he joined the faculty of the Information Engineering Department of the University of Padova, where he is currently a professor. His present research interests include performance evaluation in mobile communications systems, random access in mobile radio networks, ad hoc and sensor networks and IoT, energy constrained communications protocols, 5G millimeter-wave cellular systems, and underwater communications and networking. His work is widely cited, with a total of close to 25000 citations and an h-index of 72. He was Editor-in-Chief of IEEE Wireless Communications from 2003 to 2005, Editor-in-Chief of IEEE Transactions on Communications from 2008 to 2011, and is currently the founding Editor-in-Chief of IEEE Transactions on Cognitive Communications and Networking. He was Guest Editor for several Special Issues in IEEE Personal Communications, IEEE Wireless Communications, IEEE Network, and IEEE JSAC. He served as a Member-at-Large in the Board of Governors of the IEEE Communications Society from 2009 to 2011, and as its Director of Education from 2014 to 2015. He is a Fellow of the IEEE.
