摘要

为更好地保障低空立体组网的性能，可采用天线主瓣向上的方式覆盖低空。与传统地面组网场景相比，低空组网面临干扰小区数量多、干扰影响范围广、干扰受高度影响大等难题。分析了低空立体组网的分层特征，揭示了其干扰特性，并基于该特性，结合多小区三角投影的关系，对天线上倾场景下的低空组网的下行干扰进行了数学建模。该模型仅采用倾角以及用户与基站的相对位置信息，即可获得低空覆盖的性能，简化了低空场景下的性能和干扰分析过程。

Abstract

To better ensure the performance of low-altitude networking

the antenna main lobe can be used to cover low-altitude. Compared to traditional ground networking scenarios

it faces interference challenges such as a large number of interfering cells

a wider range of interference impact

and high interference susceptibility. The layered characteristics of the low-altitude three-dimensional networking were analyzed

and its interference characteristics were revealed. Based on these characteristics

combined with the relationship of multi-cell triangular projection

a mathematically model was developed for the downlink interference in low-altitude networking with upward-tilted antennas. This model could obtain the performance of low-altitude coverage using only the angle of tilt and the relative position information between users and base stations

thereby simplifying the process of performance and interference analysis in low-altitude scenarios.
