5G Lessons learned
With the vision to empower the vertical industries, 5G has successfully attracted attention from various industry sectors, e.g., smart manufacturing, agriculture, healthcare, logistics, and entertainment. While industries are considering how to make commercial use of 5G in their domains, some challenging use cases might not be fully addressed in 5G and, hence, are likely to initiate 6G discussions. Technical challenges (e.g., ultrahigh industrial-grade requirements with guaranteed service level agreement, etc.) along with other aspects such as social acceptance, enhancing communications between humans and things, expanding communication from terrestrial to non-terrestrial and improving cyber-physical fusion are driving many research directions to start thinking about visions and considerations for 6G. To realize these visions around 2030 and beyond, when 6G is anticipated, we have to enable support for the novel use cases and applications from vertical domains/industries, either by exceeding the capabilities of 5G or by finding methods to meet conflicting requirements. Typical vertical use cases and scenarios investigated by one6G include healthcare, maritime and aerial, factory, education, agriculture, and transportation/logistics.
To facilitate research and innovation, it is essential to develop a networked, virtualized simulation and trial platform for the deployment and testing of 6G use cases and scenarios, with demonstrable benefits and a vision when the proposed solution becomes mature. For this reason, it is important to initialize relevant activities on evaluation, testbeds, prototyping, and pilots of 6G key technologies.
- 6G enabling technology development in multiple domains, e.g., radio access, system architecture, native intelligence, sustainability, etc.
- Technology planning, elaborating principles for technology selection, roadmap evolution, and spectrum allocation requirements.
- Technology validation, joint innovation and prototyping activities leading to integration, verification, and trials.
- Requirement engineering, defining and harmonizing use cases, business plans, and go-to-market ideas.
- Regulatory aspects contributing to the evolution of related policies in accordance with the needs and possibilities due to technology development.

- 6G connected simulation and trial platform initiative aims to define a methodology for a sharable research, demonstrations, and prototyping infrastructure, whose elements will be made available to members, even if the full set of tools is still under development
- evaluation guidelines for all simulation, emulation, and prototyping methodology framework for simulations, emulations, and demonstrations is proposed with references to 3GPP for system and link-level simulation assumptions
- technology demonstration 6G use cases and key technologies
The 5G Vision Recommendation , published in September 2015 by ITU-R, an international standardization organization under the United Nations, triggered the commercialization of 5G services in 2019. Although various goals have been achieved, it is also true that there are still many tasks that are far from achieving the goals even after 4 years after commercialization.
- A variety of visionary services were expected, but there was no killer service
- Gap between 5G Vision Recommendations and customer expectations
- Need to consider various frequency bands and technology maturity
