SA Mode According to 3GPP 38.521-1

Device certification for compliance with 3GPP specifications is a crucial step in the launch of 5G NR user equipment (UE). As the demand for high-performance connectivity continues to rise, ensuring that devices meet industry standards is essential for delivering reliable and efficient service. To ensure optimal modem performance, RF pre-conformance testing, also known as design verification, needs to be initiated early in the product development process. This approach enables teams to swiftly identify and address potential issues, minimizing delays and enhancing the overall quality of the final product.The R&S®CMX500 3GPP RF pre-conformance WebGUI solution offers a fast and intuitive platform for executing NR-FR1 Standalone (SA) test cases based on the 3GPP 38.521-1 specification. Its manual verification capabilities make it particularly well-suited for early-stage validation, debugging, and step-by-step verification of test cases, leveraging the comprehensive toolset provided by the R&S®CMX500 WebGUI. Test case procedures are optimized for R&D use cases, while using the most relevant configurations from the specification.This application note serves as a comprehensive guide for R&D professionals, detailing the setup, configuration, execution, and verification of selected 3GPP pre-conformance test cases with just a few clicks in the GUI. Please note that the test steps outlined in this document require the CMX-KC661B license (SA FR1 3GPP RF Test Scenarios), in addition to the NR signaling license CMX-KS600B and the NR FR1 measurement license CMX-KM600. All descriptions, configurations and limits are based on 3GPP TS38.521-1 V18.4.0 (2024-11).

TDD 下行链路模式的 NR FR1 解决方案和技巧

5G 新空口 (NR) 是 3GPP 规定的一项无线电技术，在 3GPP R15 规范中首次被提出。此技术旨在用于三个目标用例：增强型移动宽带 (eMBB)、大规模物联网 (mMTC) 和超可靠低延迟通信 (URLLC)。其中 eMBB 实际上代表移动宽带通信自 LTE 标准以来的进一步演进。根据 IMT-2020 规定的技术性能要求，部署 5G 技术预计可使 eMBB 应用的下行链路 (DL) 和上行链路 (UL) 峰值数据率分别达到 20 Gbps 和 10 Gbps。eMBB 的典型用例包括需要海量数据的应用，例如高分辨率 8K 视频流、虚拟现实 (VR) 和增强现实 (AR) 等。在产品的设计阶段，需要在受控且确切的测试条件下验证 5G 用户设备 (UE) 可实现的最大数据吞吐量。识别数据吞吐量瓶颈以验证设备性能，根据金机进行产品基准测量可以显著改善最终用户体验。本文聚焦 5G NR 频率范围 1 (FR1)，并重点介绍 E-UTRAN 新空口双连接 (ENDC) 操作模式下的 TDD 双工模式。由于 5G NR 物理层非常灵活，本文旨在提供相关参数设置指南以激励被测设备 (DUT) 实现最大吞吐量。本应用指南描述了文档编制时罗德与施瓦茨解决方案的现状。文中显示的功能集不断演变，因此所用屏幕截图和所示参数可能有所变化。
