Japan Leads with Comprehensive 6G Technology Roadmaps

Earlier this year, in a blog post on the Connectivity Technology Blog, I explained how the XG Mobile Promotion Forum (XGMF) was formed. The XGMF aims to promote the expansion of mobile services and the development of mobile businesses to meet the evolving needs of mobile communications. Its goal is to help strengthen the growth potential of the information and communications industry by taking an international leadership role in the Beyond 5G and 6G era. It seeks to drive innovation and create new use cases that go beyond conventional wisdom and established norms.

The XGMF 6G Radio Technology Project recently published the white paper Beyond 5G White Paper 6G Radio Technology Project Ver.1.0, which presents the outcomes of research carried out by five dedicated Working Groups. These groups focused on the following areas:

In addition to these, version 4.0 of the 'Beyond 5G White Paper: ~Message to the 2030s~' has also been released. This comprehensive 361-page document explores traffic trends, market dynamics in the telecommunications sector, developments in other industries, required capabilities and KPIs for Beyond 5G, and key technology trends. It outlines a detailed vision for the 2030s, where mobile communication becomes a vital part of everyday infrastructure supporting Society 5.0.

The paper highlights expected traffic growth, use cases across 15 industry sectors, and the performance requirements needed to support them. It also illustrates Japan’s strategic approach to co-developing 6G in partnership with industry and academia. This includes integrating technologies such as AI, sensing, non-terrestrial networks, and sustainability into a cohesive system. Furthermore, the white paper underpins Japan’s contribution to global 6G discussions and aligns with international frameworks such as ITU and IMT 2030.
