Abstract

Millimeter-wave propagation characteristics and channel models are being recently studied for applicability of the fifth generation (5G) mobile communication systems. To overcome the larger path loss on the higher frequency band above 6 GHz, highly directive antennas or beamforming techniques using large array antennas can be used to establish a reliable communication link between a transmitter and a receiver. In this paper, a recently conducted channel measurement campaign is introduced which makes use of a direction-scanning-sounding technique to study channel characteristics of 28 GHz millimeter-wave propagation in indoor environments. The measurement campaign has been conducted in passenger terminals at Seoul Railway Station and Incheon International Airport, which are representative indoor hotspot regions in Korea. Based on our experimental data, we investigate the relationship between the beamwidth of antenna and r.m.s. delay spread characteristics.

基于28GHz室内信道测量的方向延迟扩展特性

为了第五代(5G)移动通信系统的适用性，最近正在研究毫米波传播特性和信道模型。为了克服6ghz以上较高频段的较大路径损耗，可以使用高定向天线或使用大阵列天线的波束成形技术在发射机和接收机之间建立可靠的通信链路。本文介绍了一项利用方向扫描测深技术研究28ghz毫米波在室内环境中传播的信道特性的信道测量活动。在国内代表性的室内热点地区首尔火车站和仁川国际机场候机楼进行了测量活动。在实验数据的基础上，研究了天线波束宽度与均方根延迟扩展特性的关系。
