Trends in Radio Frequency Policies in Japan
Yuji Nakamura (Director of Radio Policy Division, Radio Department, Telecommunications Bureau, Ministry of Internal Affairs and Communications)
In Japan, various efforts are being made to realize the Vision for a Digital Garden City Nation, which aims to solve regional problems by creating a new wave of innovation through the development of digital infrastructure. The 5G, Beyond 5G, and other radio systems are essential infrastructures for digital infrastructure development.
Against the background of rapidly increasing demand for the use of radio waves, this lecture introduces the latest trends in radio frequency policies, including the rollout of new systems promoting the more efficient use of radio waves.

Next-Generation 3D Spatial Cellular Configuration Integrated HAPS and Beyond 5G/6G in Mobile Communication
Teruya Fujii (Specially Appointed Professor, Tokyo Inst. of Tech., Fellow, SoftBank Corp.)
HAPS started as a millennium initiative in 2000 AD, but was put on hold. Recently, the "HAPS cellular system" using HAPSs has been re-evaluated as a means of expanding cellular communication service areas and as a means of communication in times of disaster, and research and development for its practical application is actively underway.
In this presentation, a three-dimensional spatial cellular configuration will be described as a next-generation mobile communication system that integrates the HAPS cellular system and the terrestrial cellular system such as Beyond 5G/6G to realize the same frequency from the ground to the sky.

REAL Base Station and Related Device Techniques for 5G and Beyond 5G mm-Wave Systems
Organizer / Chair :  Kazuya Yamamoto (Mitsubishi Electric Corp.), Kenjiro Nishikawa (Kagoshima Univ.)
More than three years have passed since 5G services started in several country's carriers. 5G sub-6 GHz services, so-called FR1 services, are rapidly becoming popular in cellular communications. However, 5G mm-wave services, so-called FR2 (28 to 39GHz) services have NOT been popular still now. From a viewpoint of device technology, in the sub-6GHz base stations, GaN HEMTs are becoming a main player for higher efficiency operation, compared to Si-LDMOS. In contrast, in the mm-wave base stations, Si-based transistors, such as SiGe HBT and SOI-CMOS, contribute to the realization of most of the real FR2 systems. This workshop will introduce REAL base station techniques and their supporting REAL device techniques for 5G and beyond 5G mm-wave systems. The feature of this workshop is that the latest information of not only Si-based MIMO and related devices but also GaN-based MIMO and related devices is given at a time.
The workshop attendees, therefore, will be able to learn and understand a variety of technical issues, their countermeasures, and the latest results related to base station transmitters and devices of 5G FR2 at a time. Thus, it is expected that this workshop will be very useful for 5G amplifier designers; students, beginners, or less-experienced circuit/device designers as well as experienced designers engaged in circuit- and device-suppliers for use in 5G and beyond 5G systems.

High-Precision Space-Time Synchronization Technology "Wi-Wi" : Recent Trends of Communication and Robotics Applications for Beyond 5G Era
Organizer / Chair :  Suguru Kameda (Hiroshima Univ.), Kenichi Takizawa (NICT)
High-precision space-time synchronization technology that can be used anywhere is one of the fundamental technologies essential for the realization of beyond 5G and cyber-physical systems, and has attracted a lot of interest. Especially, for indoor applications, the lack of practical solutions for high-precision space-time synchronization methods could bottleneck these developments.
In this workshop, we will introduce the latest technology of NICT's pioneering "Wireless Two-Way Interferometry (Wi-Wi)", including the development of compact devices with providing picosecond jitter and their applications. This workshop will cover a comprehensive range of topics from components to applications: high-performance crystal oscillators, bounded-delay communication, and robot position estimation.

Microwave Technology for Carbon Neutrality Applied to Materials Industry
Organizers :  Satoshi Fujii (NIMS)
Chair :  Koji Yamanaka (Mitsubishi Electric Corp.)
The Japanese government has stated its goal of becoming a carbon-neutral, decarbonized society by reducing overall greenhouse gas emissions to zero by 2050. The industrial sector accounts for 46% of Japan's total energy consumption, and approximately 80% of this is accounted for by the materials manufacturing industry, including steel, chemicals, and ceramics. Therefore, microwave-band electromagnetic waves, which can directly supply energy to chemical reaction fields, are attracting attention. Microwave chemistry is expected to be an energy-saving technology for materials manufacturing because of its features such as high reaction speed, selective heating, and low reaction temperature. However, there are issues of large-scale microwave heating and commercialization, as well as the need for evaluation as a lifecycle.
Therefore, this workshop will introduce high-frequency heating including microwave band and its latest technologies in actual manufacturing sites.
