Abstract—Fifth generation (5G) networks should use millimeter-wave (mmWave) frequencies to provide high data transmission rate. However, the performance of such networks significantly suffers from the Transmission Control Protocol (TCP) used by various applications for data transmission. In this article, it is shown that the data download rate in 5G networks is much lower than the capacity of the mmWave link because of the Slow Start algorithm used in the TCP. We analyze various approaches to the problem and propose to use the xStream platform for adjusting TCP parameters. This approach significantly increases the download rate and does not require any changes to the software of client devices, which simplifies the implementation of the proposed approach in real systems.

摘要—第五代（5G）网络应使用毫米波（mmWave）频率来提供高数据传输速率。但是，这种网络的性能明显受到各种应用程序用于数据传输的传输控制协议（TCP）的影响。本文表明，由于TCP中使用了慢启动算法，因此5G网络中的数据下载速率远低于mmWave链路的容量。我们分析了解决该问题的各种方法，并建议使用xStream平台来调整TCP参数。这种方法显着提高了下载速率，并且不需要对客户端设备的软件进行任何更改，从而简化了在实际系统中所提出方法的实现。
