Japan wants to seize the industrial opportunity to promote 6G research and development

Japan, which has not excelled in 5G development, is aiming at 6G (sixth generation communication technology) and has taken several measures to promote 6G research and development. In the supplementary budget, Japan has allocated funds to promote 6G research and development, in an attempt to step up efforts to promote 6G research and development, to take advantage of the market at the next track.

The supplementary budget supports the development of 6G

The Japanese government passed the third supplementary budget for 2020 at an interim cabinet meeting on December 15, the Nikkei reported. The additional fiscal expenditure reached 21.8353 trillion yen, which made the total general accounting budget for 2020 reach 175.6878 trillion yen, an increase of more than 70 percent over the 2019 budget.

Japanese media previously reported that the government will set aside 50 billion yen in the supplementary budget to promote the research and development of 6G advanced wireless communication services and strengthen public-private cooperation to help Japanese companies catch up with overseas competitors in the field of communication 5G base station infrastructure. The announced budget includes a total of 140 billion yen for 6G R&D.

Japan plans to set up a 30 billion yen fund to support long-term research and development. The National Institute of Communications Technology, affiliated with the Ministry of Communications, has commissioned private companies and universities to do 6G research and development. In addition, the government will spend 20 billion yen to build a hardware environment where companies and other institutions can test the technologies they have developed.

Meanwhile, the communications ministry will consider using spectrum royalties paid by mobile phone companies to boost the Y30bn research and development fund.

Japan’s Yomiuri Shimbun reported earlier that the government would link the fund to the Information and Communications Research Institute under the auspies of the Ministry of Public Affairs and Communications to push the technology into practical use by 2030. The government also plans to increase the size of the fund in the future, for example by levying “airwave usage fees”.

Initially, the communications ministry discussed setting up a fund of about Y100bn with the finance ministry. Japan hopes to have the core technology for a 6G system in place by 2025 and aims to have the new technology in commercial use by around 2030.

A number of measures to promote 6G research and development

Japan’s holding rate of essential patents for 4G LTE and 5G standards is lower than that of China and the United States. To reverse the lag, the Japanese government is targeting 6G as early as around 2030.

Compared to 5G, 6G is expected to be 10 times better in terms of ultra-fast communication and the number of devices that can be connected at the same time, while communication security is also expected to be improved by leaps and bounds, while 6G communication latency is only one-tenth of 5G. Japan expects 6G technology to be used in the medical and nursing fields in the future, as well as technological infrastructure to help solve social problems such as labor shortages.

To that end, Japan has rolled out a number of measures to start developing 6G.

In April, the Ministry of Internal Affairs and Communications and the Ministry of Communications issued Japan’s 2025 “6G Comprehensive Strategy” and key technology strategic goals, which will compile a comprehensive strategy aimed at promoting the establishment of key technologies in 2025 and ensuring international competitiveness through financial support and tax incentives. The goal is to increase the 6G key technology target’s share of the global infrastructure market to 30 percent by 2025 from 2 percent now, with Japanese companies’ global share of 6G-related patents increasing from 5.5 percent to more than 10 percent by 2025.

Japan’s Ministry of Internal Affairs launched its “Beyond 5G Promotion Strategy” in June to kick-start support for businesses. In 2020, the center set up by the Ministry of General Affairs will subsidize the travel expenses of enterprises to participate in standardisation-related international conferences, and will also establish a pool of talents with negotiation experience on international conferences. Through the national talent pool, it is hoped that talents who can actually achieve results in negotiations will be obtained. At the same time, companies, governments and universities will work together to discuss the direction of Japan’s research and development in key technology areas in standardization.

The Ministry of Internal Affairs and Communications of Japan and the Information and Communication Research Institute (NICT) recently launched a cooperation, in this year to open the “Beyond 5G new business strategy center”, aiming to start and carry out 6G related research work as soon as possible. At present, the launch ceremony of the center has been held on December 10. Beyond 5G new business strategy center will cooperate with the forces of production, education and officials to jointly commit to the acquisition and standardization of intellectual property rights. Major future activities will include the development of specific courses of action in the light of the latest global developments; Providing a place for Beyond 5G participants to build partnerships; Establish a database of experts related to standardization and intellectual property rights, and dispatch consultants; Hold seminars on human resource development.

The discourse power of 6G technology will be fiercely contested

At present, 5G has begun to be popularized worldwide, and some countries and enterprises have begun to aim at 6G, the next generation of communication technology. The competition in this field will be equally fierce in the future. Japan’s layout of 6G in advance is intended to be able to compete for the discourse power of 6G in the future.

Prime Minister Yoshihide Suga has said earlier that ¥1 trillion will be spent on digitization as part of the new economic stimulus package. He also said Japan would lead the development of 6G mobile technology and would set up an unprecedented Y2,000bn fund to support innovative companies over the next decade.

The United States and China are also securing research budgets and developing strategies, and “[Japan] must not fall behind” on the goal of achieving 6G commercialization by 2030, Foreign Affairs Minister RYOTA Takeda made clear. He believes that Japan should promote the standardization of research and development and intellectual property rights with the integration of industry, government and education to achieve the highest level of research and development environment in the world. He added that research will be focused on in the next five years and the results will be presented to the world at the Osaka World Expo in 2025.

The US announced the official launch of 6G trials in August, and the 6G Alliance was formed in October. Eu have also started to prepare 6 g wireless network technology, and funding a program called “Hexa – X” network planning, members include telecoms equipment maker Ericsson, action carriers Orange, Spain’s telefonica and companies like Intel, Siemens, and so on, in spite of 5 g network deployment is still in its infancy, the world has 100 wireless carriers in the limited area to provide services, and around the world have more than one area began to prepare for 6 g development. Huawei, Ericsson and Nokia, which have accounted for 80 percent of the international 5G communication market, have all taken 6G technology research and development as an important target.

The Nihon Keizai Shimbun reported on December 9 that Japan wants to promote its 6G technology to become an international standard, but from the perspective of global competition, it is quite difficult.
