The Super Smart Society Promotion Consortium (SSS Promotion Consortium), led by Tokyo Tech, held a hybrid technical forum titled International Perspectives for 6G Communications towards Super Smart Society on September 30. The event was joined by 119 participants on site and 429 participants online.
With an eye on the approaching 6G era, this fall's forum featured a total of eight speakers who introduced to the diverse audience innovative technologies and cutting-edge knowledge on a wide range of topics, including elemental technologies and wireless communication services that will help realize a super-smart society. The forum also included an exhibition introducing the technological initiatives and activities of the consortium's participating organizations.
After opening remarks by Tokyo Tech Executive Vice President for Education Jun-ichi Imura and Director Hisashi Kanazashi from the IT Industry Division of the Commerce and Information Policy Bureau at the Ministry of Economy, Trade and Industry (METI), three speakers offered their insight on the latest innovative technologies and findings in a wide range of fields relevant to the 6G era.
Professor, University of Tokyo
In his talk, Professor Hiroyuki Morikawa first introduced the changes in social and global views amidst COVID-19 and the role of digital technologies during the pandemic. He then described how to confront 5G/Beyond 5G/6G from three perspectives &emdash; entering the 5G arena, the importance of diversity, and the expansion of stakeholders. He emphasized that, with the increase in intangible assets, it is important to involve people from diverse backgrounds to identify problems, create new value, and facilitate innovations. He also touched on the importance of corporate transformation (CX) in relation to the advancement of 5G/Beyond 5G/6G.
NTT DOCOMO, INC.
Satoshi Nagata described the importance of industry-academia-government collaboration, which connects the communication industry with all other industries, using logistics as one prime example. He then highlighted the need for reviewing 5G technology, the pros and cons of 5G standardization, and the strengths and weaknesses of 5G commercialization. He also spoke about the objectives of 6G technology, the latest 6G research, and NTT DOCOMO's activities in areas such as non-terrestrial networks, intelligent reflecting surfaces, and the extension of the 6G frequency spectrum.
Director, Secure System Platform Research Laboratories, NEC Corporation
Takanori Iwai first described the importance of information network technology as the infrastructure to realize digital transformation, the role of 5G/6G networks, and end-to-end quality of experience (QoE) control. He then introduced NEC's AI-based intelligent wireless communication control technology, offering three examples: application identification technology with which the application can be identified by analyzing the feature parameters of traffic flow without seeing the content, application-aware RAN optimization with which the RAN can be automatically controlled according to the conditions of the application and network, and a remote vehicle monitoring system which can detect critical areas and send alert notifications.
At the end of the morning session, Professor Nobuyuki Iwatsuki, chair of the Consortium Steering Committee, gave a briefing on the progress of the consortium's activities.
A technology exhibition by the consortium's participating institutions was held at Tokyo Tech Front on Ookayama Campus during the lunch break. Each of the 12 SSS partners set up a booth and gave a presentation on their technology, with some institutions including both poster displays and actual exhibits. In front of the Ookayama Campus Main Building, a company conducting joint research with Tokyo Tech demonstrated a new service using 5G terminals. A live camera report of the exhibition was also available for online participants. Exhibition participants included the following organizations and teams:
During the afternoon session, five other experts shared their views on a variety of interesting topics.
Coordinator, Super Smart Society Promotion Consortium
Dean, Tokyo Tech Academy for Super Smart Society
Professor, School of Engineering
Tokyo Tech Professor Kei Sakaguchi explained the current status of 5G, and then presented his vision for Beyond 5G and 6G. He also introduced the concept of the SSS Service Platform, which integrates a wide range of technologies such as digital twin technology, multi-access edge computing, cloud technology, sensors, and actuators with 5G/6G as one element. He also introduced the Beyond 5G Test Field and Super Smart Town Ookayama built on Ookayama Campus together with the research outcomes obtained based on these creations.
Director, Beyond 5G Design Initiative, Beyond 5G Research and Development Promotion Unit, National Institute of Information and Communications Technology (NICT)
DIrector Kentaro Ishizu introduced the Beyond 5G/6G White Paper, in which technical issues were extracted by backcasting from the ideal state of telecommunications and society in the 2030s. First, four specific scenarios of people's lives in the future were presented, and a list of key technologies to realize these scenarios was clearly shown. A vision of the architecture that Beyond 5G should aim for was also presented. Ishizu also stressed the importance of discussions among people from different organizations and specialized backgrounds.
Chief technology officer, Ericsson Japan K.K.
CTO Masanobu Fujioka introduced the paradigm shift from 5G to 6G, and enumerated the technical challenges to realize this shift. He then introduced Ericsson Japan's specific efforts to solve such challenges. In particular, he emphasized the Cognitive Network that automatically configures desirable connections, the Network Computer Fabric that is an advanced technology of edge computing, network reliability and resilience, and joint communication and sensing as important future research issues.
Professor, RWTH Aachen University
Project coordinator, 6GEM
RWTH Aachen's Professor Haris Gacanin introduced the 6GEM project that he is leading. He began by describing the five research areas, six test fields, and the team composition for the project. Next, he presented the need for metaverse-ready networking technology and the technical challenges regarding its realization. He then spoke about 6GEM's efforts to solve these issues and touched on test fields for rescue robots. During the Q&A session, future collaboration between the SSS Promotion Consortium and the 6GEM project was confirmed, and concrete initiatives were discussed.
Co-Chairman, Natural Resources Working Group, Digital Twin Consortium
John Reynolds first introduced the Digital Twin Consortium, and explained the importance of digital twins and the current situation surrounding this technology. He then offered some examples of digital twin success stories. He also gave a detailed explanation of the Digital Twin Composition Platform, which enables the end-to-end construction of a digital twin. In addition, he introduced activities for integration of the technology in the telecommunications field.
To complete the forum, Professor Kotaro Inoue, dean of Tokyo Tech's School of Engineering, gave his closing remarks.
In the post-event survey, many participants of this forum left behind positive feedback:
Once again, the Super Smart Society Promotion Forum proved to be a very fruitful event for all those involved. The SSS Promotion Consortium plans to continue to hold technical forums on cutting-edge technological themes in the future.
