摘要

本文提出了一个全面的框架来分析以用户为中心的协作毫米波蜂窝网络的性能,其中多个基站(BSs)共同传输以形成协作小区。我们将非视距(NLOS) BSs和地理中心的位置建模为两个独立的泊松点过程(PPPs)。为了捕获位置相关性,将用户和视距(LOS) BSs聚集在地理中心周围。利用典型用户与干扰BSs之间的距离序列分布,得到了Thomas聚类过程(TCP)和Matern聚类过程(MCP)下干扰拉普拉斯变换的精确表达式。在此基础上,分别计算了两种聚类处理下的信干扰比(SIR)覆盖概率和遍历容量。我们的分析和仿真表明,与非合作相比,所提出的以用户为中心的协作毫米波网络提供了更高的覆盖概率和容量增益。

Modeling and Analysis of User-Centric Collaborative Millimeter-Wave Cellular Networks
This paper proposes a comprehensive framework to analyze the performance of the user-centric collaborative millimeter-Wave (mmWave) cellular networks, where multiple base stations (BSs) jointly transmit to form a cooperative cell. We model the locations of non-line-of-sight (NLOS) BSs and geographical centers as two independent Poisson point processes (PPPs). To capture the location correlation, users and line-of-sight (LOS) BSs are clustered around geographical centers. Applying the distributions of the distance sequences between the typical user and the interfering BSs, accurate formulas for the Laplace transform of interference are obtained for the case of Thomas cluster process (TCP) and Matern cluster process (MCP). Furthermore, we compute the signal to interference ratio (SIR) coverage probability and ergodic capacity under these two cluster processes, respectively. Our analysis and simulations show that the proposed user-centric collaborative mmWave network provides higher coverage probabilities and capacity gains compared with non-cooperation.
