论文摘要
3GPP空气界面标准支持仪表级位置在蜂窝网络中的位置。在MMWave频率下可用的较宽的带宽和狭窄的天线束宽,现在蜂窝网络有可能为每个用户提供子米位置位置。在这项工作中,我们提供了用于视线传播的3GPP位置位置技术的概述。我们讨论了3GPP标准所需的其他测量值,该测量标准可实现基于多路径的非视线位置位置。此外,我们通过使用现场数据来测试基于地图的位置位置算法在室内办公环境中验证概念,该位置位置算法的尺寸为35 m x 65.5 m。我们演示了与办公室的3D地图一致的到达角度和飞行信息的融合如何在28 GHz时提供5.72 cm的平均准确性,在140 GHz时为6.29 cm,超过23个接收器距离,范围超过4.2 m至32.3 m,使用了单个基础站和非线观点。我们还对基于地图的位置位置算法中遇到的典型错误进行了理论分析,并表明基于地图的算法的复杂性足够低以允许实时实现。
3GPP air interface standards support meter-level position location of a user in a cellular network. With wider bandwidths and narrow antenna beamwidths available at mmWave frequencies, cellular networks now have the potential to provide sub-meter position location for each user. In this work, we provide an overview of 3GPP position location techniques that are designed for line-of-sight propagation. We discuss additional measurements required in the 3GPP standard that enable multipath-based non-line-of-sight position location. Further, we validate the concepts in this paper by using field data to test a map-based position location algorithm in an indoor office environment which has dimensions of 35 m by 65.5 m. We demonstrate how the fusion of angle of arrival and time of flight information in concert with a 3-D map of the office provides a mean accuracy of 5.72 cm at 28 GHz and 6.29 cm at 140 GHz, over 23 receiver distances ranging from 4.2 m to 32.3 m, using a single base station in line-of-sight and non-line-of-sight. We also conduct a theoretical analysis of the typical error experienced in the map-based position location algorithm and show that the complexity of the map-based algorithm is low enough to allow real-time implementation.
