As the 5G enters a stable phase in terms of the system architecture, 3GPP Release 17 starts to investigate advanced features that would shape its evolution. This talk aims to provides an insight analysis for mobile networks beyond 5G considering the advancements and implications introduced by the evolution of softwarization, agile control and deterministic services. It elaborates the 5G landscape elaborating new business prospects, emerging use cases and key technologies that constitute the pillars for the evolution beyond 5G considering new radio paradigms, micro-service oriented core network, native IP based user plane, network analytics and the support of low latency – high reliability.
Konstantinos Samdanis received the M.Sc. and Ph.D. degrees from King’s College London in 2003 and 2009, respectively. He worked for NEC Europe, Heidelberg, between 2009 to 2016 as a Senior Researcher and a Broadband Standardization Specialist, involved in numerous EU projects, including 5G-NORMA, iJOIN, BeFemto, and standardization activities in BBF, focusing on Mobile Backhaul and 3GPP SA5 in the area of Self-Organized Networks. From 2016 to 2018 he moved to Huawei Technologies, Munich taking the role of Principal Researcher for 5G carrier networks, where he was involved in strategy and research for 5G architectures and transport networks. His main actives involved the specification of the Mobile-Transport API for network slicing in BBF and 3GPP SA5, while he was also involved as a delegate at IETF in the Network and Routing Area WG focusing on SR and VPN+. Since 2019 he is a Research Project Manager at Nokia Bell Labs, Munich involved in standardization activities on 5G core and network management concentrating on network analytics and AI/ML, while also acting as a delegate in 3GPP SA5 and SA6. Konstantinos served as an Editor on the Network Slicing feature topic at the IEEE Communications Magazine in 2017 and as Guest Editor for the IEEE JSAC Series on Network Softwarization and Enablers. He has arranged and authored a book in Green Communications with Wiley and is the author of over 80 academic publications and 30 patent applications.

The need for optimizing resource management (e.g., transmit power, channels, users) has been a constant concern in mobile communication networks and has exacerbated in 5G, where massive number of users and wide range of services are expected. The talk will provide fundamentals on the optimization process and the differences between continuous and integer optimization. The talk will also discuss some approaches to resource allocation with application in MIMO systems, dynamic spectrum allocation, OFDM communications, and spectral efficiency in 5G.
J.J. Escudero-Garzás received his Ph.D. degree in Electrical Engineering from the University Carlos III de Madrid (UC3M). He is currently with the Department of Signal Theory and Communications, UC3M. From 1997 to 2002, he worked for Spanish telcos as a Provisioning Engineer and as the Head of the Communications Network Maintenance Department. He was a Post-Doctoral Fellow with the Universitat Autònoma de Barcelona (2010-2012), and a Visiting Researcher with the University of Virginia (2013), the University of Florida (2017), and Texas A&M University (2018-2019). He has published around 40 contributions in international journals and conference proceedings. He has participated in 5 international research projects (3 of them in the USA) and more than 15 national projects and contracts with the industry. His research interests include optimization of wireless communication systems and resource management for 5G networks.

With the large adoption of small and smart objects, the Internet of Things aims to provide a large and universal access to a very heterogeneous set of devices. Specifically, the Industrial Internet of Things (IIoT) aims to connect time-critical devices, for industrial applications. These environments rely on wireless infrastructures, able to provide low end-to-end delays, and high-reliability. The slow channel hopping MAC approaches propose to combat external interference (e.g. Wi- Fi, Bluetooth) by exploiting the whole radio spectrum. For industrial applications, they also rely on a strict schedule of the transmissions: a device knows when it has to receive or transmit a frame, and when it can turn its radio off to save energy. In this talk, a panorama of the existing challenges and solutions for these channel hopping networks will be presented.
