Abstract

With the upcoming commercialization of the fifth generation (5G) mobile communication system, more and more base stations (BSs) will be deployed in urban areas and consume a large amount of energy. Hence, in order to study how to reduce BS energy consumption and provide the larger connectivity range, we present a measurement and modeling campaign of the urban macro-cellular (UMa) scenario in this paper. The channels were sounded at 3.5 and 28 GHz with the maximun horizontal distance of 240 meters, in a modern residential area. The transmitter (TX) was equipped with two antennas and was fixed on the roof of a building with 68 meters heigh, which was regarded as a BS. The receiver (RX) was installed on a cart to emulate a mobile user equipment (UE). Based on the measurement data, we propose the statistical channel model for the large-scale fading and analyze the channel characteristics in the C and millimeter wave (mmWave) bands in this UMa environment. Furthermore, we derive and evaluate the channel capacity per unit bandwidth based on our channel measurement results and model. This work provides a better knowledge of the UMa channels at sub-6G and mmWave frequency bands and guidance for the energy-efficient deployment for the 5G network coverage.
5G UMa场景下路径损耗测量与建模及信道容量分析
随着第五代(5G)移动通信系统的商用化,城市地区将部署越来越多的基站(BSs),消耗大量的能源。因此,为了研究如何降低BS能耗并提供更大的连接范围,本文提出了城市宏蜂窝(UMa)场景的测量和建模活动。在一个现代住宅区内,以3.5 GHz和28 GHz的频率进行探测,最大水平距离为240米。发射机(TX)装有两个天线,安装在68米高的建筑物的屋顶上,被认为是一个BS。接收机(RX)安装在推车上模拟移动用户设备(UE)。基于实测数据,提出了大规模衰落的统计信道模型,并分析了该UMa环境下C波段和毫米波(mmWave)频段的信道特性。此外,我们根据我们的信道测量结果和模型推导并评估了单位带宽的信道容量。这项工作有助于更好地了解sub-6G和毫米波频段的UMa信道,并为5G网络覆盖的节能部署提供指导。
