标题： Performance Analysis of Infrastructure Sharing Techniques in Cellular Networks: A Percolation Theory Approach

摘要： 在5G的背景下，基础设施共享已被认为是降低蜂窝网络投资成本的潜在解决方案。 特别是，它可以帮助低收入地区更经济地建设5G网络，进一步缩小数字鸿沟。 基础设施共享主要有两种类型：被动共享（即站点共享）和主动共享（即接入共享），分别要求移动网络运营商（MNOs）共享其非电子元件或电子元件。 由于共建共享可以在较低投资下实现更广的覆盖范围，通过渗流理论，我们研究不同的共享策略如何提供大规模连续服务。 首先，我们检查信号干扰加噪声比（SINR）覆盖图中的渗流特性以及渗流的必要条件。 其次，我们提出一个“平均覆盖半径”来基于吉尔伯特圆盘模型，以较低的基站（BS）密度近似SINR图。 最后，我们估计不同共享策略下MNOs的BS密度临界条件，并比较不同基础设施共享策略下的渗流概率。 显示英文摘要

摘要： In the context of 5G, infrastructure sharing has been identified as a potential solution to reduce the investment costs of cellular networks. In particular, it can help low-income regions build 5G networks more affordably and further bridge the digital divide. There are two main kinds of infrastructure sharing: passive sharing (i.e. site sharing) and active sharing (i.e. access sharing), which require mobile network operators (MNOs) to share their non-electronic elements or electronic elements, respectively. Because co-construction and sharing can achieve broader coverage with lower investment, through percolation theory, we investigate how different sharing strategies can deliver large-scale continuous services. First, we examine the percolation characteristics in signal-to-interference-plus-noise ratio (SINR) coverage graphs and the necessary conditions for percolation. Second, we propose an 'average coverage radius' to approximate the SINR graph with a low base station (BS) density based on the Gilbert disk model. Finally, we estimate the critical conditions of BS densities of MNOs for different sharing strategies and compare the percolation probabilities under different infrastructure sharing strategies.
