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.

Calibration and Verification Solution

The UWB (Ultra-Wideband) technology is a short range wide-band radio technology specified for device to device communication operating in unlicensed spectrum. It is an RF positioning technology that enables accurate and secure peer-to-peer ranging between mobile devices with robust resistance to interference while consuming very low energy and coexisting well with other radio communication systems. UWB is used for a variety of different applications, such as asset tracking, secure payment, personal tracker, real time location services and keyless access and start of a vehicle etc. According to ABI Research forecasts, there will be well over 1 billion UWB annual device shipments by 2026. Almost every smart phone shipped in 2026 will support UWB services.Talking about testing aspect of a UWB device, in general two test methodologies can be adopted as other wireless products, either the traditional testing mode (so-called conducted test mode) with wired RF connection between the test measurement equipment and device under test (DUT) or over the air (OTA) test mode in an OTA anechoic chamber. Sometimes, it is not always possible or necessary to perform the tests under conducted mode due to the limiting factors, e.g. cost, space, complexity and direct access to the RF connectors of the product. In this case, OTA testing is then becoming a non-evitable approach. Moreover, OTA testing reflects the usage of DUT in a real condition.In this application note, R&S® OTA test solution covering transmitter (Tx), receiver (Rx) and Time of Flight (ToF) testing in Wireless Automated Testing (WMT) environment is described. The measurement results throughout the whole document are based on NXP Trimension™ NCJ29D5 UWB automotive IC.
