AI 中文摘要
5G的发展及其向6G的演进路径使虚拟化尽可能接近天线。原生3GPP系统现在是在服务器上运行的软件，并由加速卡增强以应对计算密集型的信号处理。与此同时，射频（RF）前端仍然是专有硬件，承载着特定的物理层流程，如带通放大/调制。这种方法利用了软件的灵活性，同时保持了现代电信系统中复杂的微秒级信号处理性能。本文提供了关于在通用软件无线电外设（USRP）平台上运行的OpenAirInterface（OAI）5G协议栈的核心网和无线接入网的教程材料。一组蓝图展示了OAI提供具有不同传输能力的虚拟化5G网络的能力，以及将其与商用手机配合使用的可能性。在安装和部署说明之后，进行了配置讨论和吞吐量基准分析。我们的结果表明，使用OAI和USRP前端进行5G原型设计可以实现良好的可重复性和一致的吞吐量。
英文摘要
The development of 5G and its evolutionary path to 6G brings virtualization as close as possible to the antennas. Native 3GPP systems are now software running at servers boosted by accelerator cards to cope with computationally intense signal processing. Meanwhile, the Radio Frequency (RF) front-end is still proprietary hardware, sheltering specific PHY-layer procedures like passband amplification/modulation. This approach takes advantage of the software's flexibility while keeping the complex microsecond signal processing performance from modern telecommunication systems. This paper provides tutorial material on the Core Network and Radio Access Network of OpenAirInterface (OAI) 5G stack on top of Universal Software Radio Peripheral (USRP) platforms. A set of blueprints showcases OAI's ability to provide a virtualized 5G network with different transmission capabilities and the possibility to use it with commercial mobile phones. Configuration discussions and throughput benchmark analyses follow installation and deployment instructions. Our results show that 5G prototyping using OAI and USRP frontends can lead to good reproducibility and consistent throughput.
