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.

Comprehensive test solutions guide for production and R&D
Small cell is a compact base station with smaller form factor and lower transmission power in comparison to the conventional macro base station. It covers relatively small area and serves less users. Usually, small cell can be integrated into the existing mobile network. By the evolution of radio access technology, the role of small cell has been changing through the evolution path. In the 2G/3G time, its role was to provide coverage in corner cases. Later during LTE, networks are not just providing coverage but capacity too. Small cells were then used to provide the addition capacity where required without adding additional spectrum. Now in 5G era, network operators use densification as an important strategy to provide seamless 5G services which demand coverage, capacity and performance too. With use cases requiring the 5G millimeter wave (mmW) rollouts, it makes sense to use small cells for densification due to the propagation characteristics of mmW.In this application note, we will shed light on the testing aspects of a small cell throughout the product life cycle with particular focus on the production test solution for the small cell device under test (DUT) in FR2 (frequency range 2, mmW frequency band) in Over the Air (OTA) environment for option 6 split based on radio communication tester R&S®CMP200 and OTA chamber R&S®CMQ200. The document is complemented with more insights into test solutions used in typical R&D test applications towards the second half of the application note.
