论文摘要
在这项研究中，我们调查了用户数基于阈值的基站（BS）开/关控制的操作，当活动用户的数量小于特定的阈值时，BS关闭了BS。本文介绍了BS ON/OFF控制系统的空间分析，应用了随机几何方法。特别是，我们得出了具有基于用户数阈值的ON/OFF控件的均质网络（HOMNET）的覆盖概率的近似闭合形式表达。此外，分析得出了最大化覆盖范围概率的最佳用户数阈值。除Homnet外，我们还得出了异质网络（HETNET）的总体覆盖概率和最佳用户数阈值。结果表明，HETNET的分析似乎是棘手的，可以以与加权密度的线性组合的形式进行分析。此外，每个层的最佳用户数阈值是独立于其他层的。本文介绍的建模和分析不仅限于基于用户数阈值的ON/OFF控制的情况，而且还适用于其他带有次要修改的小说开/关。最后，通过与模拟结果进行比较，可以验证这项研究的理论贡献。
In this study, we investigate the operation of user-number threshold-based base station (BS) on/off control, in which the BS turns off when the number of active users is less than a specific threshold value. This paper presents a space-based analysis of the BS on/off control system to which a stochastic geometric approach is applied. In particular, we derive the approximated closed-form expression of the coverage probability of a homogeneous network (HomNet) with the user-number threshold-based on/off control. Moreover, the optimal user-number threshold for maximizing the coverage probability is analytically derived. In addition to HomNet, we also derive the overall coverage probability and the optimal user-number thresholds for a heterogeneous network (HetNet). The results show that HetNet, the analysis of which seems intractable, can be analyzed in the form of a linear combination of HomNets with weighted densities. In addition, the optimal user-number threshold of each tier is obtained independently of other tiers. The modeling and analysis presented in this paper are not only limited to the case of user-number threshold-based on/off control, but also applicable to other novel on/off controls with minor modifications. Finally, by comparing with the simulated results, the theoretical contributions of this study are validated.
