Abstract
Positioning problem can be solved with several approaches in 5G. This paper introduces RT (Ray Tracing) technique for small-cell Outdoor positioning and tracking for systems with distributed architecture with multipath processing gain. Proposed approach exploits highresolution angular spectrum estimation and known radio propagation environment. It solves positioning problem robustly even in NLOS cases via CoMP (Cooperative Multi Point) reception and joint processing at cloud CPU. The aim of this paper is to disclose proposed algorithm for NR and compare it to GNSS measurements.
在5G中，定位问题可以通过几种方法解决。本文介绍了一种基于多径处理增益的分布式系统小单元室外定位跟踪技术。该方法利用了高分辨率角频谱估计和已知的无线电传播环境。通过CoMP (Cooperative Multi Point)接收和云CPU的联合处理，即使在NLOS情况下也能鲁棒地解决定位问题。本文的目的是公开提出的NR算法，并将其与GNSS测量结果进行比较。
