Panel 04: Promising technologies for Beyond5G/6G

Wednesday 14 September, 15:30-17:00 (UTC +9)


The Beyond5G/6G Vision/Concept has been discussed in the world, and many white papers have been published. As the next step, it is important to discuss what kind of technologies are needed to realize the Beyond5G/6G. In this panel, the participants will introduce the technologies to realize Beyond5G/6G. Then, the participants will discuss from many points what technologies are necessary to realize Beyond5G/6G. One points are differences of user’s usage and technologies between 5G and Beyond5G/6G. The others are a key KPI, how to harmonize in the world and how to provide the highest throughput like as 100Gbps.


  1. What is a main difference of user’s usage between 5G system and Beyond5G/6G system?
  2. What is a main difference of technology between 5G and Beyond5G/6G?
  3. What is a key KPI in Beyond5G/6G?
  4. How to harmonize for realizing Beyond5G/6G technologies in the world, such as a research and a standardization?
  5. How to provide the highest throughput (like as 100Gbps) in Beyond 5G/6G system, such as a utilization of high frequency band (mmWave or terahertz) and something promising technologies?
