报告题目(Title): Grant-Free Massive Access in 5G IoT

报告人姓名(Speaker): Lieliang Yang

时间(Date&Time): 14:00-16:00, 2017.11.30

地点(Location): B240,School of IoT

报告摘要(Abstract): Future 5G IoT networks are expected to be the ultra-dense wireless networks aiming at providing a wide-range services, from high-rate continuous applications to low-rate sporadic short-burst services. Explicitly, radio access for sporadic short-burst IoT traffic based on the traditional multiple-access schemes used, such as, in LTE/LTE-A, is inefficient, due to the resultant high overhead ratio. Therefore, in this talk, we first address the main challenges of radio access in 5G massive IoT networks. Then, in order to reduce the overhead ratio, the problems and technical sulutions for grant-free massive access are explored. Furthermore, we introduce two types of low-complexity detection schemes that are efficient for operation in heavily loaded IoT systems. We emphasise the advantages, disadvantages and challenges for the practical implementation of these optional techniques. We conclude the talk by discussing some open problems for future research.

报告人简介(Biography): Lie-Liang Yang received his PhD degree in communications and  electronics from Northern (Beijing) Jiaotong University, Beijing, China in 1997. Since December 1997, he has been with the school of Electronics and Computer Science (ECS) at the University of Southampton, United Kingdom, where he is the professor of wireless  communications. He has research interest in wireless communications, wireless networks and signal processing for wireless communications, as well as molecular and nano communications. He has published 350+ research papers in journals and conference proceedings, authored/co-authored three books and also published several book chapters. The details about his publications can be found at http://users.ecs.soton.ac.uk/lly/. He is a fellow of the IEEE, a fellow of the IET (previously IEE), and a distinguished lecturer of the IEEE Vehicular Technology Society. He has served as associate editor to several academic journals, co-organized several special issues, and acted as different roles for conference organization.
