Co-evolution" of Terahertz Wireless and Existing Systems
The next-generation mobile communication standard "6G," aiming for commercialization around 2030, plays a role that transcends mere increases in communication speed. Focusing on Cyber-Physical Systems (CPS), which highly integrate the physical and cyber worlds, and Terahertz (THz) wireless, this presentation proposes guidelines centered on the "co-evolution" with existing information and communication systems. 6G is defined not as a replacement for existing technologies, but as a "co-evolution" model where existing networks and new technologies mutually enhance each other within an AI-native environment. Furthermore, regarding design principles, we describe a shift from a "device-centric" approach to a "human-centric" perspective that blends into existing living spaces and liberates human potential. On the technical side, the discussion covers progress in prioritized frequency bands, waveform design, and compact antenna technologies, as well as challenges in radio wave propagation and device heat generation. Finally, based on the international standardization trends of ITU-R, 3GPP, and IEEE 802, we summarize the prospects for a next-generation social infrastructure where existing systems and THz technology are seamlessly integrated.

Trends Toward the Integration of Terrestrial and Non‑Terrestrial Networks in Beyond 5G/6G
In the Beyond 5G/6G era, communication services are expected to provide an environment in which anyone can access connectivity anytime and anywhere. To realize this vision, communication networks are required to achieve flexible coverage and quality through satellite communications, to adopt a multi‑orbit architecture that combines geostationary and non‑geostationary satellites as well as high‑altitude platforms (HAPS) as non‑terrestrial networks (NTNs), and to further integrate with terrestrial networks (TNs). This presentation introduces domestic and international trends in NTNs that are entering the “multi‑orbit era,” as well as trends toward the integration of TN and NTN.
