Rohde & Schwarz mobile network testing launches the world’s first 5G NR network measurement solutionWith the world’s first commercially available 5G NR network measurement solution from Rohde & Schwarz, users measure the 5G NR network coverage accurately – one of the biggest challenges in network planning. With this solution, users can also verify the correct operation of beamforming and interworking between 5G and other technologies.
Test Solutions Based on R&S®CMX500 Platform
The evolution of mobile communication enters 5G New Radio (NR) era with pivotal features. Voice call service is however still considered as an indispensable element for mobile devices and worldwide network operators continue to maintain the voice service for their subscribers. In comparison to other Over-the-Top (OTT) voice services, such as WhatsApp©, Teams© etc., Voice over NR (VoNR) and Voice over LTE (VoLTE) maintain QoS, support well established handover mechanism and emergency call, and do not require to pre-install OTT app on the phone.In order to provide premium voice service and enhance the superb user experience, audio tests on mobile devices are essential before the product launch. Different audio test aspects among which acoustic, functional, performance and field tests need to be considered.This application note describes the performance test with focus on VoNR audio quality measurement via electrical interface of the mobile device. The test solution is based on R&S®CMX500 with its integrated POLQA algorithm.

Solutions and Tipps for NR FR1 in TDD Downlink Mode
5G New Radio (NR) is a radio technology specified by 3GPP and was first released in 3GPP release 15. It is designed to target three use cases, i.e. enhanced mobile broadband (eMBB), massive machine type communication (mMTC) and ultra-reliable low latency communication (URLLC). Among these three use cases, eMBB represents actually a further evolution of mobile broadband communication from LTE standard. According to the technical performance requirement defined by IMT-2020, by deploying 5G technology, peak data rates of eMBB application are expected to reach 20 Gbps in downlink (DL) and 10 Gbps in uplink (UL) direction, respectively. Typical use cases of eMBB are data hungry applications, such as high resolution 8K video streaming, virtual reality (VR), augmented reality (AR) etc.Verification of a 5G capable user equipment (UE) with respect to its achievable maximum data throughput under controllable and deterministic test conditions is an essential process during the design phase of the product. Performance centric verification through identification of the data throughput bottleneck, product benchmarking against a golden device enhances tremendously the user experience in the end.This document focuses on 5G NR frequency range 1 (FR1) with TDD duplex mode in E-UTRAN New-radio Dual Connectivity (ENDC) operating mode. As 5G NR physical layer offers a plethora of flexibility, the motivation here is to provide a kind of guideline of relevant parameter settings to stimulate device under test (DUT)'s max throughput capacity. The status quo of the R&S solutions at the time when the application note is created are described. Shown feature sets are constantly evolving, so the screenshots used and the parameters shown may change.
