While the mobile industry is now focusing on the realization of what 5G technologies promised, we can see that initial consideration about the next generation of mobile communications, i.e., 6G, is already happening. Considering the general trend of introducing new services with higher requirements over different generations of communication systems, it would be natural to expect that 6G technologies need to be developed to envision more advanced services than 5G. Examples of such new services include truly immersive XR, mobile hologram, and digital replica. Initial investigation already suggests rough estimates of performance requirements for 6G such as 1 Tbps peak rate, 1 Gbps user-experienced data rate, and 0.1 ms air latency. Use of terahertz spectrum would naturally be considered to provide such high data rate. Novel approaches, e.g., reconfigurable intelligent surfaces, further advanced duplex technologies, use of AI/ML, would need to be considered to satisfy the expected performance requirements. The proposed panel will be a good opportunity to exchange initial views about vision, technologies, and roadmap for 6G.
