论文摘要
在5G的框架内，MMWave带中发生的阻塞效应至关重要。先前的作品描述了隔离和多个链接中的障碍物的效果，用于简单阻止对象，并以数学工具（例如随机几何形状和随机形状理论）建模。我们的研究使用这些工具来表征具有$ n $链接的方案，其中包括在阻止几种阻止对象模型的情况下它们之间的可能相关性。我们包括数值评估，强调，假设链接的阻塞元素之间的独立性是过于简化的，并且无法准确描述实际情况。本文还采用了针对$ n $链接开发的公式，以优化MMWave单元中的继电器定位以增强覆盖范围，即最大程度地减少通信故障概率。我们还表明，链接预算和阻塞都会影响继电器的最佳定位，因为它们对于成功传输至关重要。
Within the framework of 5G, blockage effects occurring in the mmWave band are critical. Previous works describe the effects of blockages in isolated and multiple links for simple blocking objects, modeled with mathematical tools such as stochastic geometry and random shape theory. Our study uses these tools to characterize a scenario with $N$ links, including the possible correlation among them in terms of blocking for several models of blocking objects. We include numerical evaluations highlighting that assuming independence among the links' blocking elements is a too-brief simplification and does not accurately describe the real scenario. This paper also applies the formulation developed for the case of $N$ links to optimize the relay positioning in mmWave cells for coverage enhancement, that is, to minimize the communication failure probability. We also show that both link budget and blockages affect the optimum positioning of the relays as they are both essential for successful transmission.
