Abstract：
5G research at University of Technology Sydney covers a wide range of activities including research into antennas, signal processing, networking and devices. In this presentation we give an overview of these activities and then focus on spectrum sharing research for 5G. The high demand for wireless Internet is putting extreme pressure on better utilisation of the available radio spectrum. The expected spectrum “famine” 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 5G networks. Spectrum Sharing can be conducted at different time scales. Due to a potentially high cost of setting up the necessary infrastructure, initially the use of Spectrum Sharing may only be attractive to network operators over long time scales of months or years. This approach is currently taken in standards development activities as exemplified by the emergence of the Leased Spectrum Access concept. 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 (REMs) which need to be generated efficiently and accurately. As the deployment of Spectrum Sharing evolves from longer to shorter time scales of operation, an important design consideration is how to achieve this evolution in a seamless manner. In this presentation we give an overview of the Spectrum Sharing concept and its emergence in standards activities.
Prof. Eryk Dutkiewicz 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, and Intel on projects involving wireless sensor networks, 4G and 5G mobile communications networks and medical wireless body area networks. He is currently the Head of School of Computing and Communications at the University of Technology Sydney in Australia. Prof. Dutkiewicz has held visiting professorial appointments at the Chinese Academy of Sciences, Shanghai Jiao Tong University, City University of Hong Kong and Coventry University in the UK. He is an author of over 200 research papers and several book chapters. His professional activities in recent years included participation on various International Steering Committees. He is the General Chair of IEEE VTC 2017-Spring in Sydney.
