日本第五代移动通信系统的商用服务于2020年春季开始。本文讨论了基于时域有限差分技术的大尺度电磁场仿真对办公环境下28ghz毫米波室内传播特性的高精度预测。利用北海道大学信息创新中心的高性能计算机系统进行计算机仿真。尽管它们通常需要大量的计算机资源和较长的运行时间，但它们可以一次为我们提供包括目标在内的时域有限差分问题空间中的电磁场分布的细节。本文将LOS环境下计算得到的路径损耗指数、阴影因子、交叉极化判别等路径损耗模型参数与其他研究组的实测数据进行了比较，验证了数值结果的有效性和路径损耗模型参数预测的准确性。
The commercial service of fifth generation mobile communication system started in the spring of 2020 in Japan. This paper discusses a highly precise prediction of 28 GHz millimeter wave indoor propagation characteristics in an office environment by using a large-scale electro-magnetic field simulation based on the finite difference time domain technique. The computer simulations are carried out using the high-performance computer system operated in Information Initiative Center, Hokkaido University. They give us a detail of electromagnetic field distributions in an FDTD problem space including targets at once although they require a lot of computer resources and a long running time in general. The paper compares calculated path loss model parameters such as path loss exponents, shadow factors and cross-polarization discriminations in the LOS environment with the measured ones demonstrated by the other research groups to confirm the effectiveness of numerical results and the accurate prediction of path loss model parameters.
