Cooperating with Industry Partners to Promote 5G Large-Scale Global Commercial Deployment
In the 5G Innovation Development Summit of China’s International ICT Exhibition and Conference, IMT-2020 (5G) Promotion Group announced current progress of China’s 5G Technology R&D (research and development) Test third phase. Huawei first completed 5G NSA (non-standalone) test and SA (standalone) functional test based on 3GPP Release 15, also achieved breakthrough results in SA field test. For 5G varied commercial scenarios, Huawei fully verified different commercial products, such as macro sites and indoor sites, etc. Meanwhile, Huawei and Intel jointly completed the industry’s First Call in SA network. In pace with deep discussion on 3GPP R16 standard, Huawei was the only supplier to complete the R16 new technology test in the third phase of China’s 5G Technology R&D Test, contributing to the sustainable development of the 5G industry. With the gradual distribution of 5G commercial spectrum worldwide, the pace of 5G commercial deployment accelerated significantly. Huawei actively cooperated with the industry to provide verification results on 3GPP-based end-to-end 5G commercial products and solutions, and promoted the maturity of 5G industry chain in different countries and regions with commercial 5G plans.
In this test, Huawei’s 5G end-to-end commercial products, including gNB, 5G bearer network, and NG core, could work in NSA or SA network. In the third phase of the NSA test, key technologies such as dual connectivity were be adopted and good for introducing 5G NR (New Radio) into live network quickly. Furthermore, Huawei’ test results in the SA network showed the ability to provide excellent user experience.
In Small Cell test of China’s 5G Technology R&D Test, Huawei with 5G LampSite performed best, and then kept providing continuous Gbps-level user experience in indoor scenarios while macro sites in outdoor scenarios. In addition, in terms of deep coverage enhancement, Huawei and industry partners were jointly promoting the commercialization of uplink and downlink decoupling which enabled the cell coverage of gNB as same as that of eNodeB which was co-site with gNB. The test results showed that uplink and downlink decoupling could simultaneously improve uplink and downlink user experience especially on the edge of cell. Huawei not only kept accelerating testing progress, but also actively cooperated with industry partners. In this September, Huawei and Intel completed First Call via 5G SA network in IODT.
R16 test for standard pre-research was a very important part in China’s 5G Technology R&D Test. For the enhanced services of eMBB (Enhance Mobile Broadband), the key technologies such as R16 multi-codeword, multi-stream and the design of enhanced receiver were verified. The results showed that the spectrum efficiency of the system is up to 258bps/Hz. NR V2X (New Radio Vehicle-to-Everything) was researched and tested for uRLLC (Ultra-Reliable and Low Latency Communications) and mMTC (massive Machine Type Communications). Meanwhile AI (Artificial Intelligence) security campus as a critical 5G application was verified and explored. A large number of technologies enabling 5G applications will be included in the R16 standard, so Huawei is ready to explore industry digitalization with the vertical industry.
Yang Chaobin, president of Huawei 5G product line, said, ” In the third phase of China’s 5G Technology R&D Test , the test results showed Huawei’s strong confidence in providing operators with mature and reliable 5G end-to-end commercial products and solutions. It was also the result of the joint efforts of Huawei and many industry partners. The promotion of the 5G industry need the efforts from governments, policy regulators, operators, suppliers, instrumentation manufacturers, vertical industries in various countries and regions around the world. Huawei is willing to work together with partners to fully prepare for the successful 5G commercial deployment.”
China’s Technology R&D Test was carried out from 2016 to the end of 2018, including three phases: 5G key technology verification, 5G technical solution verification and 5G system networking verification. Huawei continued to lead in the first phase and the second phase, providing the industry with highly valuable test results. After three months of frozen R15 standard, Huawei is leading the third phase test in NSA and SA network, and cooperated with industry partners to fully support global operators to deploy 5G large-scale commercial network.
