最近的实验研究表明，城市毫米波(MmWave)信道通常同时受到视线(LOS)和几何相关的一阶反射路径的支配。在这种环境中，来自周围干扰物的任何LOS和/或反射分量都可能严重恶化链路质量。然而，在缺乏适当的毫米波网络干扰模型的情况下，分析此类影响是具有挑战性的。在这篇通信论文中，我们通过提供一个分析随机几何模型来解决这一挑战，该模型可以量化网络干扰总量。我们的研究表明，密集的毫米波网络通常是干扰有限的。几何相关的一阶反射干涉是毫米波网络分析和设计中不可缺少的组成部分。
Recent experimental studies reveal that urban millimeter wave (mmWave) channels are often dominated by both the line-of-sight (LoS) and geometry-dependent first-order reflection paths. In such environments, it is possible that any LoS and/or reflection components from surrounding interferers can critically deteriorate the link quality. Analyzing such impacts is, however, challenging in the absence of appropriate mmWave network interference models. In this correspondence paper, we address this challenge by providing an analytical stochastic geometry model that quantifies the total amount of network interference. Our study reveals that dense mmWave networks are often interference limited. The geometry-dependent first-order reflection interference is a dispensable component and must be encountered when analyzing and designing mmWave networks.
