Title: 5G and the future of communications

Abstract: Future of communications is driven by evolving human needs and multiple different technical and economical developments. Demanding new services and use cases require system level solutions and holistic architecture. 5G is an important piece but there are also many other areas of the networks we need to evolve to provide truly new services. These include transport and distributed clouds but most importantly end-to-end management and orchestration utilizing analytics and AI. We will look at the evolution of different, connected areas within the framework of the Future X architecture and what may lie further in the future.

Biography: Lauri Oksanen is Vice President for Research and Technology in Nokia. He heads The Industry Standards Group in Nokia Bell Labs, responsible for all industry activities in Nokia. He started his industrial career 30 years ago in fiber opticsin Nokia. Then Lauri moved to mobile networks where he has worked with all major wireless technologies from GSM to 5G. Lauri has worked in various advanced technology management positions covering fixed and wireless access, core, management and services, including also the HW and SW platforms and cloud and security technologies. Lauri has Master's and Licentiate degrees in Telecommunications from Helsinki University of Technology (now Aalto), where he also worked as a researcher before joining Nokia.

Title: Three Stories on IoT (Internet-of-Things) Connectivity: Ultra-Reliability, Massiveness, and Blockchains

Abstract: The future wireless landscape will feature multiple types of connectivity for the Internet of Things (IoT). The two generic IoT classes associated with 5G are Ultra-Reliable Low-Latency Communication (URLLC), and massive Machine Type Communication (mMTC). However, this initial classification undergoes a revision to accommodate new types of requirements, such as broadband transmissions or trusted data exchanges. This talk will speak about three different aspects of IoT connectivity. The first story is related to mission-critical IoT and explains why ultra-reliability is a feature that must be treated with the tools of statistical machine learning. The second story is related to massive IoT connectivity, where we revise the common assumption used in random access protocols, according to which the activation and the data of each IoT device is independent from the other devices. It is shown how massive IoT can be transformed into an ultra-reliable system when the devices transmit correlated data. The third story is dedicated to the challenges that occur when the autonomous interactions among the IoT devices are powered by distributed ledger technology (DLT), blockchain, and smart contracts. It is shown how blockchains transform the IoT traffic patterns, as well as what are the challenges that the combination blockchain-IoT poses to the communication architecture.

Title: Physical layer for next generation wireless: Lessons learned from 5G and directions for 6G

Abstract: The performance and quality-of-service bottleneck of wireless networks will always remain at the physical layer.  The main physical-layer technology component for sub-6 GHz in 5G, Massive MIMO, improves performance over conventional wireless access by orders of magnitude.  In this talk, I will explain how in the last decade, massive MIMO evolved from a wild academic idea to a vibrant research topic to a main component of 5G.  I will also talk about some important lessons learned from the development of the fundamental theory behind this technology, and some misconceptions that still prevail. Furthermore I will discuss future directions and visions for 6G technology, especially scalable cell-free massive MIMO and grant-free random access for massive machine-type communications.

Biography: Erik G. Larsson is Professor at Linköping University, Sweden, and a Fellow of the IEEE. He co-authored Fundamentals of Massive MIMO (Cambridge, 2016) and Space-Time Block Coding for Wireless Communications (Cambridge, 2003).

Title: When Quantum-Signal Processing & Communications Meet

Abstract: The marriage of ever-more sophisticated signal processing and wireless communications has led to compelling ’tele-presence’ solutions - at the touch of a dialing key... However, the ’quantum’ leaps both in digital signal processing theory and in its nano-scale based implementation is set to depart from classical physics obeying the well-understood laws revealed by science. We embark on a journey into the weird & wonderful world of quantum-physics, where the traveler has to obey the sometimes strange new rules of the quantum-world. Hence we ask the judicious question: can the marriage of applied signal processing and communications extended beyond the classical world into the quantum world?

Biography: Lajos Hanzo is a Foreign Member of the Hungarian Academy of Science, Fellow of the Royal Academy of Engineering, of the IEEE, of the IET and of the EURASIP. He is also a Wolfson Fellow of the Royal Society. During his career in telecommunications he has held various research and academic posts in Hungary, Germany and the UK. Since 1986 he has been with the School of ECS, University of Southampton, UK, where he holds the Chair in Telecommunications.
