Huawei has announced that it is the first vendor to complete a 5G NSA (Non-Stand Alone) functional test based on 3GPP. The NSA test was conducted in the third-phase of China’s 5G technology tests in Beijing’s Huairou District. The test was organized by the IMT-2020 (5G) Promotion Group, which aims to meet the ITU’s International Mobile Telecommunication system target date of 2020.
3GPP announced the completion of the 5G NR standard in December 2017. The test conducted by Huawei was based on the official protocol version of 5G NR (New Radio).
The content of the test includes the basic functions of the physical layer defined by the 3GPP standard, physical channels, link adaptation and scheduling, multi-antenna technology, EN-DC (LTE-NR Dual-Connectivity), and CU-DU(Central Unit – Distributed Unit) separation architecture. The NSA functional verification is an important part of China’s third-phase 5G technology R&D test, and will play a critical role in early implementation of 5G deployment by some leading operators.
Yang Chaobin, President of Huawei’s 5G product line, commented, “2018 is the first year of 5G commercial deployment. Huawei’s focus today is on verification of the 5G commercial system in the third-phase of China’s 5G technology R&D tests.”
“NSA and SA are required to support the co-industry ecology, and NSA can be adopted quickly in live networks in the early stage of the 5G era. SA will eventually enable digitization of the entire industry. Huawei’s completion of the NSA functional test marks its first step to leading in the third-phase of China’s 5G technology R&D test. We will continue to work with industry partners to promote the maturation of 5G commercial products and the synergy of the industry chain,” Yang added.
