由于其具有多数gabit和低延迟无线链路的潜力，因此预计毫米波（MMWave）技术将在第五代（5G）蜂窝系统中发挥核心作用。尽管在理解MM Wave物理层方面取得了很大进展，但在访问和核心网络中，协议堆栈的所有层都需要创新。离散事件网络模拟对于端到端，跨层的研发至关重要。本文提供了有关在广泛使用的开源NS-3模拟器中集成到最近开发的全栈MM波模块的教程。该模块包括许多详细的统计通道模型以及合并实际测量或射线追踪数据的能力。例如，物理和中型访问控制层是模块化的，并且可以自定义，从而易于集成算法或比较正交频施加命理命理。该模块与NS-3长期演化（LTE）模块的核心网络连接，以进行端到端连接的全堆栈模拟，并且也可以使用高级体系结构特征（例如双连接性）。为了促进对模块的理解并验证其正确的功能，我们提供了几个示例，这些示例显示了自定义MM波堆的性能以及专门用于有效利用MMWave通道的自定义拥塞控制算法。
Due to its potential for multi-gigabit and low latency wireless links, millimeter wave (mmWave) technology is expected to play a central role in 5th generation (5G) cellular systems. While there has been considerable progress in understanding the mm Wave physical layer, innovations will be required at all layers of the protocol stack, in both the access and the core network. Discrete-event network simulation is essential for end-to-end, cross-layer research and development. This paper provides a tutorial on a recently developed full-stack mm Wave module integrated into the widely used open-source ns-3 simulator. The module includes a number of detailed statistical channel models as well as the ability to incorporate real measurements or ray-tracing data. The physical and medium access control layers are modular and highly customizable, making it easy to integrate algorithms or compare orthogonal frequency division multiplexing numerologies, for example. The module is interfaced with the core network of the ns-3 Long Term Evolution (LTE) module for full-stack simulations of end-to-end connectivity, and advanced architectural features, such as dual-connectivity, are also available. To facilitate the understanding of the module, and verify its correct functioning, we provide several examples that show the performance of the custom mm Wave stack as well as custom congestion control algorithms designed specifically for efficient utilization of the mmWave channel.
