⬛ Title: Unveiling the Future: Exploring 6G Development through ICDT Integrated Networks

The 5G era marked the seamless integration of information and communication technology (ICT), paving the way for the next generation – 6G. The evolution towards 6G envisions the seamless integration of ICT with big data and artificial intelligence, giving rise to the paradigm of ICDT (Information, Communication, Big Data Technology) integration. This talk delves into the technical insights surrounding the development of 6G wireless communications from the perspective of an ICDT-integrated network. ICDT-integrated 6G is an end-to-end information processing and service system, incorporating a mobile information network characterized by robust connectivity, powerful computing capabilities, advanced intelligence, and heightened security measures. Our exploration of ICDT-integrated 6G consists of three categories of potential technologies. First, we discuss new research trends such as semantic communications and AI big models. Second, we investigate enhanced radio technologies, exemplified by integrated sensing and communications (ISAC), innovative MIMO transmission schemes, and more. Lastly, we introduce new network architectures, such as the service wireless network, digital twin network, and other new concepts. Throughout the discussion, the conceptual framework, application scenarios, and associated challenges are presented. Our analysis is complemented by system-level technical insights regarding the potential of the ICDT-integrated network paradigm.

⬛ Title: 6G and sustainability

The importance of sustainability to the welfare of humanity and the planet has become increasingly clear in recent years. Mobile wireless technologies have evolved to the extent that they are now considered critical infrastructure on which society depends world-wide. The evolution of these technologies towards 6Gprovides new challenges and opportunities to address the sustainability of 6Gand the ability of 6G to enhance sustainability in other sectors of the economy. A key to improved sustainability is to minimize the overhead in terms of energy consumed as well as materials used in enabling the use cases that 6Gwill serve. This requires flexibility during operation enabled by good design during standardization and product development, as well as smart network management during operation. Open RAN will play a role in all these aspects. This talk will address sustainability in the context of 6G and discuss these aspects.

⬛ Title: Toward Digital Twin Networks: Tools and Early Results

Digital Twin Networks (DTNs) are digital replicas of physical wireless networks. They allow for the design and operation of future wireless networks, such as 6G. Their applications range from use as “gyms” for training of environment specific communication schemes over network monitoring and control to “what-if” analyses. In this talk, we discuss the required steps and tools to create physically accurate and environmentally specific DTNs. We show how scene geometries can be accurately captured and how ray tracing allows to model radio propagation. Further, we propose differentiable ray tracing as a method to automatically learn electromagnetic material properties from channel measurements. Finally, demonstrate the benefits of training neural receivers for a specific environment and conclude the talk by a discussion of open challenges in the field of DTNs.

⬛ Title: Building a Connected world with Network Digital Twins – Opportunities and Challenges

A Digital Twin is the digital representation of a physical object, system or process, which runs alongside the real world counterpart and provides a linkage between the physical , digital, and human worlds. Digital Twin technology has been adoptedly various industries to model complex dynamic systems with the aim to increase efficiency, productivity, quality, safety and to optimize costs. A Network Digital Twin (NDT) is the twin of a communications network, or some part of one. Today, communication services have become an essential part of modern societies, and are expected to become even more heterogenous to meet thneeds of emerging, highly dynamic use cases with stringent requirements. A Network Digital Twin can serve as a key enabler of effective management of today’s and future communication networks and its services. An NDT’s dynamicbehavioral modelling and situation awareness capabilities allow for realistic real-time testing of network changes, without jeopardizing the physical network. This presentation outlines NDT principles, capabilities and interworking with the Digital Twins of vertical industries to build a connected world (e.g. metaverse), illustrated with tangible examples from Nokia.

Dr. Venki Ramaswamy, MITRE, USA

⬛ Title: O-RAN and MEC Enabled Architecture for “Network-as-a-Sensor” System

Integrating sensing functionality into communication infrastructure enables distributed sensing capability that is required for accurately and reliably predicting a radio environment. This capability is very critical in a variety of applications, not least in spectrum sharing use-cases (e.g., CBRS systems). This feature eliminates the need for an external dedicated sensing capability that could put additional restrictions on transmissions and operations thereby improving efficiency and performance. In this talk, we propose a new architecture that relies on programmable switches, multi-access edge computing (MEC) and the O-RAN RIC to enable a very dynamic and intelligent spectrum sensing capability. This approach can embed a sophisticated distributed sensing capability to existing cellular infrastructure that can natively do sensing for critical applications. Finally, we discuss some challenges and future research directions.
