From product ecology to industrial ecology, NI 5G new air interface test layout | 'Next next city'

Not long ago, the International Telecommunications Standards Institute 3GPP approved the 5G Release 15 independent network (SA, standalone) standard, plus the non-independent networking (NSA, non-standalone) standard adopted at the end of 2017, so far the 5G new air interface (NR, new The first version of the radio was officially frozen and released. Combined with the time node that 5G was officially commercialized in 2020, the full version of the 5G standard of the first phase was officially launched, marking the 5G communication industry entering the sprint phase. Accompanied by semiconductors, Network infrastructure, test and measurement, or software, manufacturing and other manufacturers, are fully committed to launch the corresponding solutions to meet the needs of the 5G market.

At the 22nd GTI Workshop that just came to a close, test and measurement industry leader NI (National Instruments, National Instruments, NI) teamed up with well-known Skyworks Solutions to showcase Skyworks' 5G new air interface equipment and 5G RF chip test. The solution, and using the NI software-defined PXI platform, tested the products developed by Sky5TM (a unified platform developed by Skyworks) to realize revolutionary 5G applications.

Covering NSA and SA double standards, NI helps Skyworks 5G new air platform landing

According to reports, the NI test solution for Sky5TM fully supports the NSA and SA standards. The NI software-defined PXI platform can quickly verify the RF and DC performance of integrated products, and combines NI RF vector signal transceivers (VST) on hardware. Technology, providing instantaneous bandwidth up to 1 GHz and excellent DC measurement performance. Therefore, NI can meet the wide range of 5G new air interface testing requirements of the Sky5TM platform, including test carrier aggregation and wideband digital predistortion (DPD).

Luke Schreier said: 'NI provides tests, measurement tools that meet the requirements of the 3GPP R15 standard, and help the entire industry quickly adapt to the current state of the market and development. 'The NSA architecture is upgraded based on the original 4G network, NI has achieved The way to change the software to adapt to different protocols under this architecture; and the benefits of the SA architecture is more significant, through the independent 5G core network, can better support 5G large bandwidth, low latency and large connections and other services, and Customized services can be provided according to the scenario to meet the business needs of various users.

Sub-6G first, millimeter wave Subsequently, NI product layout ecologically easy to deal with 5G spectrum challenges!

Many well-known, spectrum resources are very limited. The choice of spectrum is repeatedly discussed in the process of 5G definition, and ultimately attributed to unification. At the beginning of 5G research, many people are full of expectations for the possibility of 5G using millimeter waves, because the frequency resources of millimeter wave More abundant. However, the current consensus in the industry is that the 5G communication spectrum of mobile terminals will be concentrated in the sub-6GHz band in the early stage. In order to meet the early demand for sub-6 GHz 5G new air interface applications, semiconductor companies have launched corresponding solutions. Solutions such as Skyworks have developed a fully integrated solution with bandwidths up to 200 MHz designed to support the architecture of mobile terminals.

For the new air interface requirements of Sub-6G 5G, NI has officially launched a reference test solution. The key component is the flexible NI-RFmx new air interface measurement software, which can be matched with different high-performance RF measurement hardware according to customer requirements. Helping customers reuse the same instruments and measuring equipment at various stages of product development, greatly shortening the test and product launch cycle. 'Sub-6GHz spectrum application will be the first to be introduced in the market, while 5G new air interface puts forward to the RF front end. High RF specifications require more time-to-market for products. NI's excellent test solutions offer tremendous advantages from lab validation to production line testing, which is a point of confidence for NI! ' Luke Schreier said.

He added that the deployment of sub-6GHz is hot today, and NI has seen some vertical industries adopt it, so it has launched products to meet market demand. Not only that, NI promotes an ecological overall product layout from the lab. To the production line, from software to hardware, of course, covers the entire communication spectrum. In the field of millimeter wave applications, NI also has a great investment: In addition to the flexibility of software, engineers can flexibly match through different hardware. The NI test solution can realize the functions of different frequency bands. In addition, in NI millimeter wave test equipment, the hardware architecture includes different parts such as baseband, intermediate frequency and RF millimeter wave. By replacing different modules, engineers can Realize the horizontal expansion of the band function.

The 5G cooperation ecology is constantly improving. How does NI promote the 'cross-border' test of the ICT industry?

In the field of 5G communication, NI is further expanding the eco-cooperation map. According to reports, NI is working with Samsung on the field test of 5G communication system. Simulating 5G terminal through NI software-defined radio platform, implementing test user equipment (Test UE), NI test And Samsung's IoDT (interoperability test) includes sub-6GHz and millimeter wave bands. The 5G NR standard will also be explored at the highest performance level, utilizing the full available bandwidth and maximum in a full 2X2 MIMO configuration with downlink rates exceeding 3Gbps A number of component carriers (8). 5G networks represent a new generation of revolutions that promise to deliver revolutionary unrestricted experiences with faster data, lower latency, instant access anywhere, anytime, and the capacity of billions of devices To cope with such a huge application prospect, the performance of the test system must not only be improved, but also the cost needs to be reduced. In the face of such a convergence of industry trends, NI is actively promoting 'cross-border' testing: Take the automotive market as an example, the automotive industry The focus is very different from the communications industry. Customers in the automotive industry are more concerned about whether the security of the system is adequately guaranteed. This indicates that the test system needs more
