Abstract: Wireless information and communication technologies (ICT) have been already researched and developed for many years, and results in many successes in academia and industry. However, the more successful research and a business are, the more competitive and deeper their research and business are used to be for challenging unsolved problems. To break through the problems and make a new paradigm it is necessary to approach any other technologies such as data science, metaverse, security, quantum, AI/ML computing, chat GPT, DX, etc. with wireless ICT. In a medical healthcare field, wireless body area network (BAN) has a huge potential to create innovation by promoting integrated research and development with cloud networks and data science such as integrated BAN/5G/AI platform. This talk focuses on comprehensive research, development, standard, regulation, field trials, business, and social services of universal platform with advanced information communication technology (ICT) and AI data science to achieve sustainable medical healthcare and other SDGs. 5G and Beyond 5G(6G) infrastructure networks could be applied with dependable wireless BAN and machine-learning with data mining for medical social platform using advanced ICT and data science. In particular, NICT projects on brain-machine-interface (BMI) and elderly people day care using ultra-wide band(UWB) wireless BAN and machine-learning are introduced as examples of integration among ICT, AI, and medical science. To manage make comprehensive design and operation of such a universal platform is not so easy but a key for sustainable success. This speech addresses latest business promotion with clinical trials, international standard of wireless BAN with enhanced dependability such as IEEE802.15.6ma, ETSI SmartBAN, and regulation update with regulatory scientific approach, and bigger market of the universal platform in automotive industry, social infrastructure maintenance, etc. Moreover, education of such a balanced expert for multidisciplinary fields could be covered.

6G WAVEFORM OPTIONS

Professor, Istanbul Medipol University

Abstract Today’s wireless services and systems have come a long way since the rollout of the conventional voice-centric cellular systems. While 4G indicated that the evolution of cellular systems was directed more towards broadband connectivity than voice communications, 5G promised a paradigm shift with promising applications such as massive machine-type connectivity and ultra-reliable low-latency communication for variety of use cases including Industry 4.0 and Internet of things (IoT). This trend of increasing heterogeneity in terms of use cases and applications is bound to continue with the next-generation networks with even more stringent requirments related to cost, power efficiency, spectrum efficiency, extreme reliability, low latency, robustness against diverse channel conditions, cooperative networking capability and coexistence, dynamic and flexible utilization of wireless spectrum.
Given that wireless connectivity is becoming an imperative part of our existence, not just from the communication but also sensing perspective, it is important for the enabling technologies to keep up with the ever increasing requirements. Consequently, 6G envisions a network empowered with intelligent, aware, and flexible technologies that can scale with the various use cases, applications, and deployment scenarios. The emergence of software-defined networks allows the
automatic configuration of devices and their parameters, systems, and services according to the user’s context. Some of the more-popular technologies in this regard include integrated sensing and communication, non-terrestrial networks, non-orthogonal techniques for increased efficiency, higher frequency bands (mmWave and THz), smart radio environments etc.
A fundamental part of any wireless communication standard is the PHY/MAC design. In this regard, the current OFDM technology has enjoyed unprecedented success with it being the only waveform being used for multiple generations of cellular systems (albeit with the introduction of multiple numerologies). However, given its limitations in terms of satisfying the new requirements, it is high time to look at potential alternatives for 6G PHY. Accordingly, in this presentation, we will identify the waveform design criteria for the upcoming 6G standards. The potential directions and research opportunities to address the challenges and requirements of the 6G vision will be discussed. Some of the discussions can be listed as below:
- Waveform for integrated sensing and communication
- mmWave and THz waveform design issues
- Multi-connectivity and synchronization
- NTN and waveform relations
- Secure waveforms
- Flexibility in waveform design
- Non-orthogonal waveforms
- Hybrid waveforms and multi-numerology
- OFDM, OTFS, OTSM, FMCW

Future Life With Beyond 5G/6G And R&D Activities In NICT
Kentaro Ishizu
Director, Beyond 5G Design Initiative
NICT
Abstract: In the 2030s, services will become more diverse, not only from traditional networking companies but also from various industries. These services will rely on advanced Beyond 5G/6G technologies that are being actively developed through research and development efforts. However, the current mobile communication system’s architecture primarily emphasizes network performance and is not designed to effectively support a wide range of potential systems. In this discussion, we will start by outlining our vision for life in the 2030s based on a white paper published by NICT. We will then delve into the R&D activities required to realize this vision. We introduce a novel concept of Beyond 5G as a cross-industry service platform, where systems from different industries are thoughtfully organized and optimized for users. We will also showcase the architecture for Beyond 5G/6G, along with practical demonstration systems that have been implemented using this
architecture. Our goal is to foster collaboration across different industries, making this presentation as accessible as possible to researchers
from a wide range of fields.
Enhancing Angle Estimation In MmWave: When Nonuniform Array Meets Hybrid Beamforming

Abstract: The millimeter wave (mmWave) band provides abundant bandwidth suitable for future wireless networks and services emphasizing on intelligence everywhere that relies on integrated communications, control and computation. The short wavelength and high attenuation of mmWave necessitate massive miltiple input multiple output (mMIMO) techniques. However, the cost, power comsumption and heat dissipation issues make implementing mMIMO challenging. The hybrid beamforming (HBF) architecture stands out as a practical tradeoff between these issues and performance. In general the performance of HBF is limited by the number of RF chains which is usually much smaller than the number of antenna elements. In this talk, we consider non-uniform array processing to alleviate the performance loss of HBF and enhancing the degree of freedom (DOF), hence detectable signal dimension, beyond the number of RF chains. An HBF structure with non-uniform array connection will be introduced to avoid the ambiguity often seen in angle of arrival (AOA) estimation in HBF systems. The related analog sub-array design and more effective signal processing algorithms, such as those based on compressed sensing, in order exploit as much potential DOF as possible will be discussed. AOA estimation examples will be presented to show the superior performance of the proposed HBF architecture.
