Abstract

In this work, we implemented line-of-sight (LoS) ray tracing functionality to investigate problems in millimetre-wave propagation modelling and network planning in 3D city model environments. First, we validated an existing LoS propagation probability model expressed as an exponential rule with the link distance. By fitting ray tracing simulation results under different scenarios to the model, the relationships between key parameters in the model and factors including the building density and the transmitter height were qualitatively analysed. Next, we developed a network planning framework for a multi-hop outdoor urban network by formulating a mixed-integer linear programming problem which minimises the overall deployment cost through optimal site selection. Taking the sets of potential site locations and potential links as inputs, we selected a subset of the sites that comprise a tree-structured network that satisfies all the user demands at a minimum deployment cost. We also analysed the time required for solving this optimisation problem in order to provide a prediction of the execution time for larger-sized problems.

城市5G毫米波网络:视距概率和最佳站点位置

在这项工作中，我们实现了视距(LoS)光线追踪功能，以研究3D城市模型环境中毫米波传播建模和网络规划中的问题。首先，我们验证了现有的LoS传播概率模型，该模型表示为与链路距离的指数规则。通过将不同场景下的光线追踪模拟结果拟合到模型中，定性分析了模型中关键参数与建筑密度、发射机高度等因素之间的关系。其次，我们开发了一个多跳室外城市网络的网络规划框架，通过制定混合整数线性规划问题，通过最优选址最小化总体部署成本。将潜在站点位置和潜在链接的集合作为输入，我们选择了包含树状结构网络的站点子集，该网络以最小的部署成本满足所有用户需求。我们还分析了解决此优化问题所需的时间，以便预测大型问题的执行时间。
