Abstract

The integration of Positioning, Navigation, and Timing (PNT) services within the 5G non-terrestrial networks (NTN) infrastructure is necessary to eliminate the need for a GNSS receiver in the user terminal. Using the positioning reference signal (PRS) in an NTN scenario presents significant challenges, such as interference analysis from the transmission of multiple PRS signals. This study provides a stochastic model for the interference generated by PRS transmissions in a 5G NTN scenario. This model has been derived empirically from a Monte Carlo simulator designed specifically for this purpose, showing that the distribution that best fits the interference is a Generalized Extreme Value (GEV) distribution. The parameters of this distribution are also modeled based on the PRS configuration. Therefore, a designer can use this model to evaluate the probability of encountering certain levels of interference.

5G NTN 中定位参考信号的干扰分析与建模

在5G非地面网络（NTN）基础设施中集成定位、导航和授时（PNT）业务是必要的，以消除对用户终端中GNSS接收器的需求。在NTN场景中使用定位参考信号（PRS）存在重大挑战，例如来自多个PRS信号传输的干扰分析。本研究为5G NTN场景下PRS传输产生的干扰提供了一个随机模型。该模型是由专门为此目的设计的蒙特卡罗模拟器经验导出的，表明最适合干扰的分布是广义极值（GEV）分布。该分布的参数也基于PRS配置建模。因此，设计者可以使用这个模型来评估遇到一定程度的干扰的概率。
