摘　　要：高频段由于具有非常大的频谱宽度而受到下一代(5G)移动通信系统的青睐.高频段同时具有大的传播损耗、准光学特性等特征.为了能够充分挖掘、选择和评估可用高频段,需要对高频段信道进行充分测量和研究.目前高频段信道测量设备主要有基于矢量网络分析仪的探测器和定制化宽带探测器两种.该文对当前开展的高频段信道测量活动进行总结,包括天线配置、测试场景与关注参量,以及相应的测量设备.最后对几个新提出的高频段信道模型进行介绍,如METIS、MiWEBA、mmMAGIC、5GCM、3GPP-HF等,指出现有模型的主要特点和适用范围,以及预计未来测量和建模方面加强的方向.Because the high frequency band has a very large spectral bandwidth,it is a promising candidate band for the next generation （5G） mobile communication systems. High frequency band also has strong propagation loss, quasi-optical characteristics and other characteristics. In order to fully utilize, select and evaluate the available high frequency band, it is necessary to adequately measure and research on the high frequency channel. Currently there are mainly two kinds of sounders, customized broadband and vector network analyzer based, are used for high frequency channel measurement. The paper reviews the high frequency channel measurement campaigns currently undertaken, including the antenna configuration, scenarios, focused parameters and the corresponding measurement equipments. Finally, several high frequency band channel models newly proposed, e. g. METIS, MiWEBA, mmMAGIC, 5GCM and 3GPP-HF, are summarized and pointing out the key features and application scope of the existing model, as well as the direction on channel measurement and modeling to be strengthened.
