近来，第五代移动的通信系统（5G）已经被广泛研究以适应增加的移动的用户业务。在5G系统中，尽管期望利用6GHz频带以上的更高频带，但是由于与微波频带相比不同的无线电信道特性，因此仍然需要对移动的通信的适用性进行详细研究。在本文中，11 GHz频段MIMO信道测量进行了街道微小区环境。结果表明，与微波波段的结果相比，镜面路径的延迟和角扩展较小。与室内环境的测量结果相比，散射信号分量较弱。该结果有望为更高频段的MIMO信道建模提供参考。
Recently, the fifth-generation mobile communication system (5G) has been widely investigated to accommodate increasing mobile users' traffic. In the 5G system, although the utilization of the higher frequency band above the 6 GHz band is expected, the detailed investigation for the applicability to the mobile communication is still necessary because of different radio channel characteristics compared with microwave bands. In this paper, 11 GHz band MIMO channel measurements were conducted in a street micro-cell environment. The result shows that the delay and the angular spreads of the specular paths were smaller compared with the results in the microwave band. The scattered signal component was weak compared with measurement results of indoor environments. The result is expected to utilize for the MIMO channel modeling in the higher frequency band.
