Abstract：
The high demand for wireless Internet including emerging Internet of Things (IoT) applications expected to dominate 5G networks is putting extreme pressure on better utilisation of the available radio spectrum. The expected spectrum “crunch” requires highly efficient radio resource management schemes with low complexity and high responsiveness to the changing network conditions. Spectrum sharing is regarded as an essential approach to regaining access to otherwise unused spectrum and it is considered an essential component in the development of IoT and 5G networks. Radio frequency regulatory agencies in Europe and USA have put forward more flexible frameworks for spectrum sharing allowing use of spectrum under a secondary license. These frameworks referred to as Licensed Shared Access in Europe and Spectrum Access System in USA assume initially a long spectrum sharing timescale between incumbents and other users.
Spectrum sharing can be conducted at different time scales. As the time scale of the operation of spectrum sharing decreases, the possibility for utilising more available spectrum holes increases. However, the shorter time scale brings with it challenges. Efficient decisions regarding the use of spectrum sharing require accurate knowledge of the spatial and temporal spectrum use in a geographical area of interest. This knowledge can be represented in Radio Environmental Maps which need to be generated efficiently and accurately. In this presentation, we give an overview of the spectrum sharing concept and its emergence in standards activities for 5G networks. We also present our research on spectrum sharing including methods for efficient and accurate generation of Radio Environmental Maps and a practical radio spectrum measurements testbed.
Bio：
Professor Eryk Dutkiewicz obtained his Bachelor of Electrical and Electronic Engineering from the University of Adelaide, Australia in 1988, his Master of Science in Applied Mathematics from the University of Adelaide, Australia in 1992 and his PhD (Telecommunications) from the University of Wollongong, Australia in 1996. From 1999 to 2004 he worked at Motorola Laboratories in Sydney where he managed a wireless research laboratory. During that time he was also deeply involved in the development of the popular WiFi technology. Since returning to academia in 2004 he has worked closely with industry partners including Motorola, Freescale, Intel Nokia. He is currently the Head of School of Electrical and Data Engineering at the University of Technology Sydney in Australia. He is an author of over 250 research papers and several book chapters. His professional activities in recent years included participation on various International Steering Committees. He was the General Chair of IEEE VTC 2017-Spring in Sydney.
