Title: The implications of Open RAN adoption on AI-driven Management of 5G and Beyond Networks
Abstract: Current 5G networks and incoming beyond 5G (B5G) networks are expected to support a wide range of emerging use-cases such as holographic communication and autonomous vehicles, with diverse requirements in terms of throughput, latency, and reliability. Supporting such multi-faceted requirements mandates a highly flexible end-to-end network architecture, enabled by network slices spanning from the Radio Access Network (RAN) to the mobile core. Legacy RAN solutions rely on closed-box functions and proprietary interfaces, which makes RAN and end-to-end slicing difficult. Therefore, in recent years, there has been a push toward adopting the principles of disaggregation, virtualization, and open interfaces in the RAN, known as Open RAN (ORAN). The concept of ORAN improves the flexibility of the mobile RAN, and benefits operators by increasing innovation rates and reducing operational costs. However, realizing the full potential of ORAN dramatically increases the complexity of resource management in the infrastructure and necessitates automated network management powered by advanced data processing and AL/ML techniques. This talk will discuss some of the challenges and benefits of incorporating ORAN into 5G autonomous network management with particular focus on programmable network monitoring, unsupervised learning for fault detection and localization, and reinforcement learning for online slicing and admission control.

Title: Why 6G has to be a federation of autonomous domains?
Abstract: The communications solutions evolve in order to fulfil new expectations regarding network functions and services, and the progress in hardware and software technologies fuels this evolution. The ever-growing functionality of networks makes networking solutions more and more complicated. Network virtualization combined with Service Based Architecture changed the way of network design, providing, on the one hand, multiple benefits, including low cost of total ownership, short time to market and efficient usage of (shared) infrastructure resources.
On the other hand, the approach (or its present implementation) raises some issues related to NFV-based orchestration, 5G-based network slicing, integration of different service platforms (O-RAN, MEC and 5GC), reliability and the use of AI-driven management. It is expected that the 6G network will solve the shortcomings and will be able to cope with new requirements. These requirements, among others, include end-to-end self-manageability, the ability to use NTNs and exploit the mobility of NTNs nodes (this includes UAVs as mobile computing nodes) and the ability to use virtualized resources of the end-user terminals.
The expected features of the 6G network, like D2D communication and NTN integration, make it a good candidate for a mission-critical solution. However, such a solution has some additional requirements. In the talk, 5G constraints and how to fulfill the above mentioned requirements will be discussed. A high-level concept of 6G, designed as a federation of flexible and intelligent domains, will be presented as an exemplary solution. The proposed integration of domains is immersive – it allows one domain to offer services to other domains.

Bio: In 1994 Sławomir Kukliński received a PhD with honours from Warsaw University of Technology, and since then, he has been an assistant professor. His PhD thesis concerned neural networks (now part of AI). For about 20 years, he also works for Orange Polska as Research Expert. At the beginning of his career, he was involved in digital signal processing for military (radar systems) and non-military applications (voice compression and recognition).
Later, he worked on wireless mesh networks (MANET), VANET (V2X), and SDN. For about 15 years, he has been involved in research concerning autonomic network management and mobile networks. Actually, he is working on network slicing 5G, 6G and autonomic and cognitive techniques applied to network management and control. As a principal investigator, he was involved in more than ten EU-funded projects, including FP6 MIDAS, FP7 4WARD, FP7 EFIPSANS, Celtic COMMUNE (Cognitive Network Management under Uncertainty), 5G!Pagoda, 5G-DRIVE, 5G!Drones, MonB5G and Hexa-X (6G flagship project in Europe). He has been involved in ITU-T standardization concerning future networks (SG13). Slawomir Kukliński has published more than 80 scientific papers, has been a TPC member of many conferences and has given several invited keynotes.
Title: Novel Index Modulation Techniques for Low-power Ultra-high Data Rate System
Abstract: Wireless data demand is continuously increasing, and thus, additional breakthroughs are required to cope with beyond 5G requirements, where the sub-TeraHertz (THz) bands are considered as key enablers. Recent communication standards considered different techniques like MIMO spatial multiplexing, higher QAM modulation order, and wider bandwidth to increase data rate. However, the higher-order QAM are limited by RF impairments and technological limitations that increase at higher carrier frequencies. In order to increase the spectral efficiency while using low order QAM, Index Modulation (IM) was introduced. In this talk, a generalized MIMO Spatial Multiplexing (SMX) system with IM is discussed, where a part of the information bits is conveyed in the signal domain (e.g. QAM) and the second part is conveyed through the indexation of the filter shape in the filter IM domain that generalizes time and frequency IM domains. This particular Filter Shape (FS) IM is called FSIM. In this talk, a comparison will be provided between existing systems and recent advanced schemes achieving high spectral efficiency (SE) gain with the help of IM for wireless sub-THz communications.
