[Invited Lecture] Interference Power Estimation Method Using the Radio Map and the 3D Map for Spectrum Sharing
SunaoMiyamoto, Takeo Fujii (UEC) SR2021-93
Abstract (in Japanese) (See Japanese page) 
(in English) In recent years, spectrum sharing technology is attracting attention to solve the problem of spectrum shortage. In order to maximize the spectrum utilization efficiency while avoiding interference from the Secondary User to the Primary User, it is necessary to perform highly accurate propagation estimation. In recent years, a radio map is attracting attention as a highly accurate radio propagation estimation method. The radio map is constructed by collecting observed data sets acquired by terminals in a database server and statisticalized for each area mesh. Therefore it is necessary to estimate the height pattern characteristics and extrapolate the observed values on the ground level in order to estimate the radio propagation in places where there are no observed data sets such as the upper sky. In this papter, we propose a height pattern estimation method using the radio map and the 3D map. In the proposed method, find the main structure on the propagation path, and find a dominant propagation path between antennas. Then, estimate the height pattern by calculating the loss value due to the structures around the propagation path using the main structure and the dominant propagation path information. The evaluation results using the measurement datasets show that the estimated performance of the proposed method is improved compared to without extrapolation.
