密集小小区无线网络理论分析简史
A Brief History on the Theoretical Analysis of Dense Small Cell Wireless Networks
摘要：
本文深入探讨了密集和超密集小小区无线网络的基本原理，讨论了密集和超密集小小区网络与稀疏小小区网络根本不同的原因，以及为什么后者中众所周知的容量与基站（BS）密度的线性缩放定律不适用于前者。更详细地，我们回顾了以下因素对超密集网络（UDN）的影响：（i）封闭接入操作和视线条件，（ii）近场效应，（iii）小小区BS和用户设备（UE）之间的天线高度差，以及（iv）空闲模式使能的小小区BS相对于UE的剩余。结合所有这些网络特性和特征，我们提出了一个更现实的容量缩放定律的UDN，这表明（i）存在一个最佳的BS密度，以最大化的面积频谱效率（ASE）为一个给定的有限的UE密度，以及（ii）存在一个最佳的UE密度，可以同时调度在网络上，以最大化的ASE为一个给定的有限的BS密度。
英文摘要：
This article provides dives into the fundamentals of dense and ultra-dense small cell wireless networks, discussing the reasons why dense and ultra-dense small cell networks are fundamentally different from sparse ones, and why the well-known linear scaling law of capacity with the base station (BS) density in the latter does not apply to the former. In more detail, we review the impact of the following factors on ultradense networks (UDNs), (i) closed-access operations and line-of-sight conditions, (ii) the near-field effect, (iii) the antenna height difference between small cell BSs and user equipments (UEs), and (iv) the surplus of idle-mode-enabled small cell BSs with respect to UEs. Combining all these network characteristics and features, we present a more realistic capacity scaling law for UDNs, which indicates (i) the existence of an optimum BS density to maximise the area spectral efficiency (ASE) for a given finite UE density, and (ii) the existence of an optimum density of UEs that can be simultaneously scheduled across the network to maximise the ASE for a given finite BS density.
