Light-based Wireless Communications
6G research is on the way, and one element in 6G is ‘new spectrum’ in order to be able to cope with the ever-increasing mobile data traffic. The visible light and infrared spectrum is 2600 times larger than the entire radio frequency spectrum. Visible light communications and LiFi are therefore, target technologies in 6G. Crucially, the optical spectrum already underpins our data backbone through the massive deployment of core and metro networks. Consequently, there are optical devices that are optimized for high-speed communications. Although the step of taking this spectrum into the wireless world seems straightforward and logical, there are a few fundamental challenges that need to be overcome. This course will describe these challenges and will offer solutions based on more than two decades of research in VLC, and even longer research in infrared optical wireless communications. We will go on to provide a general background to the subject of optical wireless communications, followed by a brief summary of the history of visible light communication VLC and wireless infrared (IR) communication. We will discuss the relationship between VLC and LiFi (light fidelity), introducing the major advantages of VLC and LiFi and discuss existing challenges. Recent key advancements in physical layer techniques that led to transmission speeds greater than 100 Gbps will be discussed. Moving on, we introduce channel modelling techniques, and show how this technology can be used to create fully-fledged cellular networks achieving orders of magnitude improvements of area spectral efficiency compared to current technologies. The challenges that arise from moving from a static point-to-point visible light link to a LiFi network that is capable of serving hundreds of mobile and fixed nodes will be discussed. We will also discuss the benefits of optical intelligent reflecting surfaces (IRSs). Finally, an overview of recent standardization activities will be provided given that a new LiFi standard, IEEE 802.11bb, is expected to be fully ratified by the end of 2022. Lastly, we will discuss commercialization challenges of this disruptive technology and provide results of pilot studies.

Next-Generation Unlicensed Spectrum Technologies
Wi-Fi and cellular networks carry most of the wireless access traffic together and will continue to do so. So far, the cellular network is mainly for wide-area coverage and mobility, while Wi-Fi is mainly for indoor use thanks to its much lower deployment costs. This divide-and-conquer approach succeeds because the combination of licensed spectrum for cellular networks and unlicensed spectrum for Wi-Fi enables different models of spectrum use, different business models and different wireless infrastructure owners. However, the traditional boundaries that differentiated earlier generations of cellular and Wi-Fi are blurring, with 5G NR-U supporting specific enterprise requirements. This is not just about the number of connections, but also for the range of use cases that will grow and in directions beyond those we can envisage today. What will happen for the Next-Generation Unlicensed Spectrum Technologies? This session will gather experts actively participating in the field of unlicensed spectrum of Wi-Fi and cellular networks. New use cases of unlicensed spectrum technologies will be discussed, from traditional telecoms to emerging vertical applications. Topics in scope of this session will also include new technologies for Wi-Fi 7&8, 5G and beyond, such as innovative access schemes and co-existence schemes, as well as the regulation aspects regarding the introduction of unlicensed spectrum into cellular networks. The session will also explore the possible future deployment and business models of the two technologies, especially in the vertical industry scenarios, as well as the complementary/harmonization between the two technologies. We expect a lively exchange of views, since the relationship between the two unlicensed spectrum technologies is a bit diverse. It is hoped that new research and development activities will be stimulated by such discussions that will help define future technology evolution and business models.

The First 15 Years of Edge Computing and What’s Next
This is the decade of 6G development. We will discuss the fundamental differences 6G will likely mark compared to 5G, the key R&D opportunities in 6G, and the unique “lab to life” 6G deployment at Purdue University’s Innovation Campus in Indiana, USA. We will go through a roadmap toward an edgy, open, heterogeneous 6G, where applications will drive the evolution of architecture and optimization this decade.
XR/AR Evolution and Commercialization Aspects
With the increased adoption and take-off of 3GPP 5G-NR in commercial networks, interest in eXtended Reality (XR) devices including Augmented Reality (AR), Virtual Reality (VR) and Mixed Reality (MR) has also significantly increased. These devices would merge the world as experienced through text, images, videos, etc. thereby enhancing and augmenting real/quasi-real experiences in commercial applications. Since such augmentation is contingent on increased data rates and reduced latencies, 5G-NR is naturally poised to address these challenges. The scope of this session would be to present the state-of-the-art in XR evolution aspects as seen from a technology perspective in Release 18 (and beyond) of 5G-NR as these releases start to fructify. This session would also chart out the future scope of commercialization aspects in this area and present a well-rounded overview of this area including the opportunities and challenges in the road from paper design to products and commercialization. The speakers in this session include well-established researchers in XR with a fundamental understanding in the arenas of R&D, standardization and practical deployments.
End-to-End Time-Deterministic Networking Technologies
With the advent of 5G era, interest in time-sensitive services is growing, and even more so with upcoming 6G. Hyper-immersive interactive service such as hologram communication, and high-precision vertical service such as remote control of machine/ robot/drone are two representative time-sensitive service types. In order to realize the services end-to-end, not only mobile communication but also packet network technology must be considered together. This presentation will briefly introduce recent packet network technologies guaranteeing in-time/on-time and lossless delivery of data to meet the service requirements, discuss their limitations and issues, and share ETRI’s approach to solve them.
The Next Generation Computing Paradigms For Ambient And Immersive Computing
Recent advances in AI are enabling the next generation of AI applications across new emerging fields like metaverse, ambient computing, and immersive computing. These AI applications greatly enhance the existing user experiences while seamlessly enabling novel user experiences on existing and new devices. For instance, it is expected that between 2020 and 2026, VR market will shoot from a value of $17.25 billion to around $184.66 billion while AI being one of the most important drivers of the VR revolution. To enable AI features in these new emerging fields and novel use-cases, 5G is perhaps the most valuable technology in addition to increased computing capability needs. Through faster connections and exchange of data, AI applications can reduce latency, improve mobility and immerse their users deeper into these new AI-enabled experiences. In this talk, we will provide an overview of how the rise of 5G connectivity could eliminate some of the major bottlenecks and problems that would otherwise prevent companies and users from embracing and enabling metaverse, ambient computing, and immersive computing. Combined with other disruptive technologies like AI and IofT connections, 5G will represent a new frontier for metaverse, ambient computing and immerse computing.
Evolution of Edge Computing and Edge AI Towards 6G
Mobile edge computing (MEC) is a 5G/6G paradigm in communication and computing. The main feature of MEC is to push mobile computing, AI, control, and storage to the network edge (e.g., servers near base stations and access points) so as to enable intelligent, computation-intensive, and latency-critical applications at the resource-limited mobile devices. The promised gains of MEC have motivated extensive efforts by both the academia and industry on developing relevant technologies. In particular, MEC will provide a platform for realizing edge intelligence in 6G systems. In this session, several leading researchers from the industry will discuss the latest advancements in edge computing and edge AI in the areas and how relevant technologies will impact the ongoing 6G evolution.

Quantum Key Distribution (Qkd) from Academic Research to Industrial Practice
With the significant publicity campaigns around Quantum Technologies and specifically Quantum Communication, and the flurry of Standardization and Certification as well as industrial cooperation activities (ETSI, ISO, ITU-T, CEN-CENELEC, GSMA) we intend to have a serious discussion on the practical applicability of Quantum Key Distribution (QKD). On the one hand it is paramount to understand what are the realistic or to be anticipated risks against which QKD can ensure protection. On the other it is to be elaborated, how QKD can be compared to suggested alternatives, specifically Post Quantum Cryptography (PQC). Further the utilization strategy of QKD is to be discussed. Very often some partially unrealistic and often exaggerated requirements such as dedicated fiber infrastructures and trust centers at short distances plus expectations for a specific and very expensive technology are put forward that make QKD technology appear unaffordable financially, This is to be addressed critically in conjunction with issues such as authentication in these cases. It is to be understood what practically relevant but affordable use cases can be addressed using QKD.
Reconfigurable Intelligent Surfaces (RIS) for 5G-Advanced
With the deployment of 5G networks and the start of standardizing 5G-Advanced, both academia and industry are exploring actively into future technologies for next generation wireless communication systems. Reconfigurable intelligent surfaces (RISs) have been envisioned to reduce the energy consumption and improve the spectral efficiency of wireless networks by artificially re-configuring the propagation environment of electromagnetic waves. RIS-based transmission, in which the large number of small, low-cost, and passive elements on RIS only reflect the incident signal with an adjustable reflection amplitude and phase shift without requiring a dedicated energy source for radio frequency processing, decoding or encoding, is completely different from existing active relays and open up a new area of research for wireless communications. RISs are being discussed actively in regional and global standardization development organizations and are likely to become a critical component of 5G-Advanced networks.
5G Towards 6G - The Continuation of Paradigm
Mobile communication technologies have been changing our lives at a steady pace with a regular cycle of decade. Now 6G is becoming one of the hot keywords while we are still evolving our 5G standards to 5G Advanced for extension of its business deployment covering more and more business sectors including verticals. In the past generations, we have seen how mobile services and applications boosted the innovation, industry eco-system and economy, and gradually re-shaped our human society. When we talk about the future of mobile communications, we must learn from the past and face concurrent challenges. Following the paradigm of mobile communications technology evolution, adopting mobile services in vertical segments, and ensuring sustainable market development will enlighten the evolution path towards 5G-Advanced and 6G. Continuous advancements of emerging wireless technologies will fuel the smooth 5G Advanced evolution towards 6G.
AI-Enabled Communication Networks
With the recent deployment of commercial 5G systems, the technology evolution is moving towards more autonomous, self-configuring, intelligent networks and devices to support the new forthcoming data- and process-hungry applications of the next generation of the communication system. AI is considered a good fit for complicated non-convex optimization problems that are lacking optimal analytical solutions, and computation-intensive problems that are too costly to solve in real-time. Research works have provided promising results in applying AI in different use cases, ranging from physical- to application-layers, from edge- to core network-services and applications. Taking also into consideration the advances in big data computing technology, AI applied to the wireless domain has the potential to reshape the design and deployment of wireless networks and enable the formation of a self-adaptive, more power-aware, smart, and resilient communication ecosystem. In the proposed panel, we will explore and discuss the potentials and challenges of leveraging AI for the next generation of communication networks.

Intelligent Autonomous Vehicles
Intelligent and autonomous driving has been emerging as one of the most prominent advances in the industry of vehicles. Road vehicles including passenger cars and trucks as well as aerial vehicles like drones are expected to be capable of sensing their environment and moving safely with little or no human input, thereby making people’s daily lives safer, more efficient, and more convenient. Connectivity is considered as a key component in enabling such an advance, and 5G has been designed from its beginning as a communication tool for intelligent and autonomous vehicles. 5G’s high data rate is suitable to deliver rich map and sensor information to the vehicles in order to enhance environment sensing. Support of ultra reliability and low latency communications (URLLC) in 5G allows the vehicles to send and receive critical information that should be delivered with a very short latency and almost zero error for the safe decision of vehicles’ maneuver and reaction to an emerging risk. There are a lot of efforts to launch successful commercialization of 5G-based intelligent/autonomous vehicles, and in parallel with it, evolution is ongoing towards Beyond-5G in the standardization organizations and academia to find out technical solutions that can address the industry requirements better.
Non-Terrestrial Networks (NTN)
In recent years, due to the development of innovative satellite launch vehicle technologies, the cost of launching and producing satellites has rapidly decreased. Consequently, a large number of operators have emerged to provide global communication services through low-orbit satellite clusters such as OneWeb, SpaceX, Project Kuiper, and Telesat. Also, the global market of unmanned aerial vehicles such as smart airlines, flying taxis (air taxis), and drones is expected to increase rapidly. The area of communication that provides Gbps grade internet service will be expanded to non-terrestrial networks (NTN) to support not only service enhancement and coverage extension on the ground, but also in a three-dimensional (3D) space and at sea. Therefore, terminals will be able to receive Gbps grade internet service anytime, anywhere. In order to provide such a service, B5G/6G NTN technologies for providing communication coverage in the 3D space are required beyond the limit of a ground-oriented mobile communication service. It is expected that it will be possible to provide reliable internet services to various moving vehicles in the air and on the ground through integrated satellite and terrestrial network technologies. The integrated satellite-terrestrial networks leverage on various technologies to make the architecture of heterogeneous networks operationally effective as seamless service coverage, robust service supporting ability, and high-efficiency performance. New handover schemes to tackle frequent handover due to satellite movement will be developed. The improvement of beam management will be required for mobility of satellites and aerial vehicles, long round-trip time (RTT), wide beam coverage, and various beam types. Antenna technologies for LEO satellite payload will be crucial. Also, the support of mobile edge cloud and edge intelligence through NTN connectivity will be important. 3GPP NTN Standardisation Roadmap Networks Detached from Ground – the Rise of NTN in 5G Advanced and 6G Taming Aerial Communications with 6G Smart Surfaces What about Satellite Communication in 6G?
