摘要：
在5G背景下，基础设施共享被视为降低蜂窝网络投资成本的潜在方案，尤其能帮助低收入地区更经济地建设5G网络，进一步弥合数字鸿沟。基础设施共享主要分为被动共享（即站点共享）和主动共享（即接入共享）两类，分别要求移动网络运营商（MNOs）共享非电子元素或电子元素。由于共建共享能以更低投资实现更广覆盖，本文通过渗流理论研究不同共享策略如何提供大规模连续服务：首先分析信号与干扰加噪声比（SINR）覆盖图的渗流特性及渗流必要条件；其次基于吉尔伯特圆盘模型，提出“平均覆盖半径”以近似低基站（BS）密度下的SINR图；最后估算不同共享策略下MNOs基站密度的临界条件，并比较不同基础设施共享策略的渗流概率。
英文摘要：
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.
