| Abstract for Research Report |
Innovations in the fundamental systems that support information and communications are required to meet the numerical targets for performance indices in the various use cases targeted by the next-generation mobile communication systems (B5G/6G). In addition to terrestrial cellular networks, development of vertical wireless communications, i.e., UAVs (Unmanned Aerial Vehicles, so-called drones), stratospheric communications platforms (HAPS), and low earth orbit satellite (LEO) communications, such as Starlink, is being conducted with large investments of capital. In addition to upgrading existing technologies, the development of new technologies is also underway. In addition to upgrading existing technologies, there is a need for innovation in completely new technologies that are not bound by existing methods. a significant change in direction, analogous to the change in direction from 3G (CDMA) to 4G (OFDM), requires a robust mathematical theory to serve as the foundation. Therefore, in addition to the insight to extract the essence of communications, ideas and mathematical theories from different fields are required. Through the organization of workshops, the exchange of human resources engaged in fundamental research that will lead to true innovation will be promoted. Millimeter waves (radio waves in the frequency band above 30 GHz), which have strong linearity, have conventionally been used for automotive radar and other applications, but after 5G, they will also be used for mobile communication applications. Against this background, research on Joint Sensing and Communication (JSAC), which combines and integrates radar (sensing) and communication functions, is being conducted worldwide from the basic theoretical level to the practical application level. The invited speaker, Dr. Hamdi Joudeh, has given important research results[2] in information theory-based research that provides the mathematical basis for Joint Sensing and Communications (JSAC). Future collaborations with the participants are expected. |
