Abstract (in Japanese) (See Japanese page) 
(in English) In sixth-generation (6G) mobile communication system, it is expected that a extreme hgih data rate coomunication with a peak data rate over 100 Gbps should be provided by exploiting higher frequency bands in addition to millimeter-wave bands such as 28 GHz. The higher frequency bands are assumued to be millimeter wave and terahertz wave where the wider bandwidth is available compared with 5G, and hence 6G needs to promote research and development to exploit so-called terahertz wave targeting the frequency from 100 GHz to 300 GHz. In the terahertz wave, there are fundamental issues that straightness and reachable distance of the radio wave are stronger and shorter than that in the 28 GHz band, respectively. To solve these issues, it is very important to clarify channel characteristics of the terahertz wave and establish a channel model, to advance 6G radio access technologies suitable for the terahertz wave based on the channel model, and to develop radio-frequency device technologies for such higher frequency bands. This report introduces a direction of studies on 6G radio access technologies to explore the higher frequency bands and issues on the radio-frequency device technologies, and then a potential of extreme hgih data rate over 100 Gbps is clarified by basic computer simulations in 100 Gbps transmission using the 100 GHz band.
