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).

Soluciones y consejos para NR FR1 en modo de enlace descendente con TDD

5G New Radio (NR) es una tecnología de radiotransmisión especificada por 3GPP y se publicó por primera vez en la release 15 de 3GPP. Está diseñada para dar respuesta a tres casos de uso, a saber: banda ancha móvil mejorada (eMBB), comunicaciones tipo máquina masivas (mMTC) y comunicaciones de ultra-alta fiabilidad y baja latencia (URLLC). De estos tres casos de uso, eMBB representa en realidad un paso evolutivo de la comunicación de banda ancha móvil del estándar LTE. Conforme a los requisitos de rendimiento técnico que define IMT-2020, con el despliegue de la tecnología 5G se esperan con la aplicación eMBB velocidades de transferencia de datos máximas de hasta 20 Gbps en el enlace descendente (DL) y de 10 Gbps en el enlace ascendente (UL), respectivamente. Los casos de uso típicos de eMBB son aplicaciones con alto consumo de datos, como el streaming de vídeo en 8K de alta definición, realidad virtual (VR), realidad aumentada (AR), etc.La verificación de un equipo de usuario (UE) compatible para 5G en cuanto a su caudal de datos máximo en condiciones de test controlables y determinísticas es un proceso fundamental durante la fase de diseño del producto. La verificación enfocada en el rendimiento mediante la identificación de cuellos de botella que frenan el caudal de datos, la evaluación comparativa de productos con respecto a un «golden device», mejora de forma decisiva la experiencia de usuario.Este documento se centra en el rango de frecuencias 1 (FR1) de 5G NR con modo dúplex por división de tiempo (TDD) en modo de operación E-UTRAN New-radio Dual Connectivity (ENDC). Puesto que la capa física de 5G NR ofrece una enorme flexibilidad, la motivación consiste aquí en aportar algo similar a una pauta de ajustes de parámetros relevantes para estimular la capacidad de rendimiento máximo del dispositivo bajo prueba (DUT). Se describe el statu quo de las soluciones de R&S en el momento en el que se creó la nota de aplicación. Los conjuntos de funciones expuestos varían continuamente, de modo que las capturas de pantalla y los parámetros mostrados pueden cambiar.
