Huawei took the lead in completing the third phase of China 5G technology research and development, steadily marching to R16 standard

Communications World Network News (CWW) Recently, Huawei took the lead in completing the third phase of the 5G technology research and Development test for 3GPP R16 and the future of new features and new technology verification test. At the PT show, Huawei is also actively demonstrating the latest results. As an important part of the third phase of China's 5G technology research and Development test, the new features and technologies for the 3GPP R16 and the future are tested to validate the new technologies and functional standards that will be introduced in the 5G three typical scenarios in R16 and future standards. In strict accordance with the IMT-2020 (5G) development of the "R16 and the future of new features and technology verification test Method" specification ("Specification"), to become the first to complete all three scenarios under the required test cases of equipment manufacturers, for the December 2019 will be frozen 3GPP R16 international standards to make important contributions.

Comprehensive test enable 5G application scenarios

Enhanced mobile Broadband (EMBB, enhanced mobile Broadband) has been extensively applied and validated under the R15 standard, but it can still be improved by introducing new features and new technologies in R16 to support richer 5G scenarios. In the R16 standard discussion, Huawei proposed a series of candidate key technologies such as multi-code word, DMRs (demodulation Reference Signal) optimization enhancement, downlink signaling Design Enhancement Receiver, the application of these technologies will greatly improve the performance of multi-user MIMO system. The current test shows that Huawei has brought the system spectrum efficiency up to 258bps/hz industry records through these new technologies, and the spectrum efficiency of the whole network system has increased by more than 50% compared with the R15 standard technology.

In the low Singo reliable (urllc,ultra-reliable and lo Latency Communications) scenario, after the completion of a single station static multipoint test, Huawei has for the first time in the mobile multi-station network scenario of various packet size business delay and reliability testing. Using polar coding, optimized Harq (Hybrid Automatic Repeat Request) technology combined with UCNC (User centric and No Cell) to optimize the design, the test results show that in a continuous coverage area of 5G macro stations over a kilometer, The transmission reliability is higher than 99.999% while the interface transmission delay is less than 1ms.

While validating key technologies and network performance optimization technologies, Huawei is also actively exploring and validating future 5G applications. In this test, for the URLLC enable scene of one of the Nr v2x (New Radio vehicle-to-everything) communication, through the UU and SL (sidelink) air Interface Integration Design, verify the new vehicle architecture, in the multi-modem collaboration and multi-vehicle collaboration, For target vehicles, especially when the signal-to-noise ratio of the target vehicle is not high, the signal-to-noise ratio can be increased and the throughput improved through collaboration (SL), which lays the foundation for the wide coverage application of one of the URLLC enabling scenarios.

5G three aspects of technology to improve

For the massive IoT communication (Mmtc,massive Machine Type communication) scenario defined in the new features and technologies for R16 and future testing methodology, Huawei has the ability to support billions of extreme connectivity through SCMA technology for the small packet business , further combined with the 3GPP standard situation, for uplink large connection video transmission, the use of upstream NR interface, so that the video business running smoothly on the 5G network, in this experiment with the completion of the 5G enable AI Campus application demonstration, to show 5G to enable the powerful intelligent campus function.

Dr. Dongwen, Huawei Wireless CTO and 5G chief scientist, said: "There are three technical improvements in 5G: extreme speed, very low latency, massive connectivity. Huawei has actively explored and re-validated these three aspects in the research and development of 5G technology in China, and has obtained more than the results of the ITU (International Telecommunication Union)-defined indicators in the second phase of the 2017 test, and Huawei continues to explore and validate the R16 standards in the third phase. As of now, we have achieved a certain result, which makes our vision of 5G larger. ”

5G is in the critical phase of the standard determination, June 2018, the world's first edition of 5G Standard R15 released, R16 standard SI/WI launch. The complete 5G standard, which meets the full requirements of the ITU (International Telecommunication Union), will be completed in December 2019. Huawei continues to prepare for the R16 standardization, support the standardization of 5G Enhancement Technology, continue to explore in the field of system performance improvement, through more 5G typical application Fusion test research, promote 5G business and application development, provide high quality 5G network for each vertical industry.
