| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | A key issue in the research and development of next-generation mobile communication systems (Beyond 5G/6G) is the availability of novel frequency bands. Currently, the frequency band below 6 GHz, which is suitable for mobile communications, is already tight, and technologies for highly efficient utilization of finite spectrum resources are required. Therefore, many researches have been conducted on the practical application of dynamic spectrum sharing technology for the effective use of spectrum. For this technology, it is important to precisely estimate the spectrum utilization of the wireless system and the propagation characteristics changes in each environment. Furthermore, in Beyond 5G/6G, non-terrestrial networks (NTNs) such as satellites and drones are expected to be utilized to expand the communication area, which will require spectrum management in the height direction. In this paper, we have designed and developed a 5-dimensional (5D) spectrum database that extends the spectrum database of radio environment information from the 2-dimensional plane of latitude and longitude to a 3-dimensional space that includes height information, as well as time and frequency. We describe the details of the design and the test results of the experiments. | |
