中文摘要: 5G / B5G移动通信系统的高带宽、高可靠性和低延迟的通信需求需要更多新技术的支持. 毫米波由于其丰富的频谱资源和极高的带宽容量而成为5G/B5G移动通信系统的研究热点之一. 不同于以往由有线网络主导的互联网架构, 如今的移动互联网已经成为无线接入网和高速核心网的融合. 但是目前对毫米波端到端通信传输性能的研究工作还相对较少, 而且多采用仿真实验. 本文利用真实网络设备, 通过开展真实网络环境下的实验, 对毫米波链路基本传输性能和5G/B5G毫米波网络端到端通信系统中TCP传输性能进行测量分析, 研究5G/B5G毫米波网络传输过程中的链路瓶颈, 为设计毫米波端到端网络传输协议, 提高网络传输吞吐率奠定基础.

Abstract:The high bandwidth capacity, high reliability, and low latency communication requirements of 5G/B5G mobile communication systems require more novel technology support. Millimeter wave (mmWave) has become one of the research hotspots of 5G/B5G mobile communication systems due to its rich spectrum resources and extremely high bandwidth capacity. Different from the past Internet architecture dominated by wired networks, the mobile Internet has become a fusion of wireless access networks and high-speed core networks, so the network transfer performance is facing huge challenges. However, the research work on the transfer performance of mmWave end-to-end communication is still relatively small and simulation experiments are basically used. In this study, we use the actual network devices to carry out experiments under real network environment to analyze the link bottleneck in the transfer process of 5G/B5G mmWave mobile network by measuring the basic transfer performance of 5G/B5G mmWave link and the end-to-end TCP transfer performance in the 5G/B5G mmWave mobile network. The results lay the foundation for designing mmWave end-to-end network transmission protocols and improving network transmission throughput.
