The following is the full text of Wang Zhiqin's speech:
Good morning, ladies and gentlemen.
Also on behalf of the 5G Propulsion Group, we welcome you to attend this year's 5G Summit.
The 5G Propulsion Group was established in 2013, and this year is also the seventh year. It has done a lot of work in key technological innovation, standard-setting, industrial organization and internationalization. So at present, our Propulsion Group has also made some structural adjustments after entering the 5G commercial year this year. We can see that at the work level, we will continue to promote the formulation of 5G enhanced technology standards, network evolution and the continuous promotion of follow-up industries, especially in the application area, hoping to better support the development of the entire application industry.
The whole work is also promoted by the joint efforts of the relevant main enterprises at home and abroad.
Firstly, in terms of 5G international standards, because the release of the first version of R15 laid a foundation for the development of the whole 5G industry. At present, the world is in the process of standard-setting of the second version of R16. In the process of developing the three scenarios on the left, we will continue to enhance the reliability of low latency and high reliability in R16, that is, the application for common scenarios of industrial Internet and vehicle networking. In R17, mass machine-like communication is taken as a new enhancement direction for 5G scenarios.
In addition, the development of 5G follow-up enhancement technology is industry-oriented on the one hand, and will be put on the agenda in larger airspace, such as the combination of UAV and satellite, including the further enhancement of 5G's positioning, network architecture and slicing capabilities, which will provide a support for the development of all walks of life to realize 5G's business vision.
In terms of 5G international standards, the Propulsion Group also focuses on four directions. One is vehicle networking, which is also the coexistence and cooperation of LTE and 5G NR vehicle networking. Especially for the design of new 5G vehicle networking scenarios and the combination of some network technologies, including edge computing and slicing.
In the field of industrial Internet, the emphasis is also on the design of low delay and high reliability schemes, especially how 5G can better support time-sensitive networks and achieve precise time synchronization.
In the aspect of network automation, it is also to build a more systematic and complete functional framework on the basis of existing standards, including the improvement of service interface and the business process of assistant analysis with large data.
The security aspect is also to do more identification and user protection enhancement for Internet of Things scenarios. In addition, we are actively promoting 256-bit algorithms for 5G applications.
In the process of network construction, optical fiber is very basic. Therefore, for the 5G carrier network, the promotion group has been continuing the development of related technologies and industries. One is to determine the overall three aspects of the network bearer architecture, but also to promote the formation of a variety of technical solutions, the release of 5G bearer network architecture and technical solutions of the white paper.
In terms of industry promotion, we mainly test and evaluate the interoperability characteristics of high-speed optical module technology and products. We also published a white paper on 5G optical module.
For the follow-up development, one is intelligent control and synchronization. In these two areas, there are still many technologies and problems to be further explored, including some slice control issues, including the openness of some interfaces.
So at this summit, we will also publish relevant white papers on 5G synchronous networking architecture.
Based on these explorations and practices, there are also many projects in the international standardization work of ITUT5G last year and this year, and new innovations through laboratories have become the standard.
Next, 5G promotes technology development through the pilot working group. After completing equipment testing, this year's focus is to promote the development of terminal chips to support the industrial capabilities of NSA and SA. Participants in the test include four 5G chips, six 5G system devices, support NSA and SA two networking architectures, the frequency band is two main bands, one is the original 3.5G, and the other includes 2.6G.
In fact, terminal chip testing is divided into two parts, one is the test of the terminal chip itself, and the other is the interoperability between the chip and the system. So the whole test and industry benchmark version is based on 3GPP R15, which is the December 2018 version. The main indoor function tests are carried out, including NSA and SA tests, bandwidth and frame structure in the band, as well as wireless interface layer 1-3 protocols, and flexible scheduling.
Outdoors, we also conduct a comprehensive test of throughput, latency, including the success rate of many businesses and long-term retention performance through a small-scale test network in Huairou area.
In this picture, the green part is interoperable between the chip and the system.
This chart also highlights the current testing of four terminal chips themselves. Huawei Hess's balong5000 chip is designed for SA and NSA, and Hess has completed all the tests. Qualcomm participated in the test mainly in the X50 chip, designed for NSA, and completed a comprehensive test. The chip content of Mediated Development Section is oriented to SA and NSA. At present, all indoor tests have been completed, and outdoor performance tests are also in progress. The test of violet ray sharpening is beginning.
In addition, we also carried out interoperability test between terminal chip and system. Here we also see the test contents of four chips and six systems. According to the different support functions, Heise has completed the test of many manufacturers. Qualcomm is mainly a function of NSA, and the test work of the manufacturers both indoors and outdoors is still covered quite well, especially in the case of Hess.SamsungSome surveys have been made. In the work of Lianfa Section and Ziguang Zhanjie, the cooperation with some manufacturers is more prominent.
From the content of the test, one is the peak throughput test of indoor single terminal, so from the whole test results, after a period of testing, terminal chips can generally achieve transmission performance of more than 80% of the theoretical peak, so the figure on the left actually focuses on the single terminal downlink peak throughput. Quantity performance, three manufacturers, we use chip 1, 2, 3 different colors to make a representation, so at 3.5G, whether NSA or SA, the downlink peak rate is basically 1.3 to 1.5Gbps. The downstream of 2.6 GHz is about 1.5 to 1.8 Gbps under the two modes. The downward peaks of NSA and SA are basically the same.
Uplink transmission performance, in 3.5G band, the upstream peak measurement is 170Mbps in NSA mode, and SA will have an improvement, which will reach more than 270Mbps. The same result was found at 2.6G. NSA was 130 Mbps and SA could be increased to more than 160 Mbps. So we think that in SA mode, upstream can achieve dual-stream, and there is still a significant increase in speed.
Interoperability testing is also usedMobile phoneIt is also a good validation to test the actual peak rate in the field with the indoor results from the whole performance conditions. Downlink can reach Gigabit download rate, while upstream can reach 100 megabit basically. So the picture on the left is downward and on the right is upstream. Under the condition of NSA, the downlink is 1.0 to 1.4 Mbps, and the SA is basically the same value. The upstream is 100 to 170 Mbps, and the SA can reach 240 to 280 Mbps.
Interoperability testing has a business-long retention test. The whole business operates continuously over a long period of time, so from the performance of the current test, the average throughput of each chip in the field test can basically reach 360 to 760 Mbps, which is also the perception of actual use in the future. The success rate of handover is also better, reaching 100%.
In addition, in the initial stage, we all focused on 3.5G, so in this year and the second half of last year, we started to promote the development of the whole industry at 2.6GHz, and also clarified its frame structure. So the whole half year, also with the operator to promote a better effect. At present, five enterprises in the function, radio frequency and field performance have carried out a relatively complete 2.6G test, the overall performance level reached the same level of industrial maturity as 3.5G band.
In addition to the macro base station, we also began to test the chamber subsystems of each manufacturer. Basically, the overall configuration of 100MHz and 4 transmitters and 4 receivers is basically the same. Overall, the whole function and overall performance are relatively perfect, so the five enterprises have completed the chamber subsystem testing work well.
In addition, 5G voice solution, we also hope that at the beginning of 5G business, you can solve 5G voice business well, how to carry voice.
One way is to drop voice directly back to 4G, which is provided by the existing way of 4G. Another way is to provide VoNR voice service in 5G packet domain. On the basis of accumulation of 4G experience, all enterprises can better support this work. Of course, due to the limitations of terminals, Huawei has achieved better end-to-end VoNR testing work in terms of verification, ZTE started phase. Close the test.
In addition, we are now very concerned about the research and development of 5G millimeter wave technology, which is also a supplementary technology to consider the industry and application scenario of millimeter wave. Therefore, this year's focus is on key technology validation. It is expected that in August, we will complete three millimeter-wave technical specifications this year and officially start the testing of key technologies of millimeter-wave.
Under the condition that the network and industry chain are relatively mature, people pay more attention to the application. One is vehicle networking. LTE V2X is a foundation of 5G vehicle networking. In the previous stage, we formed a relatively complete industrial chain including chips, terminals and vehicle-mounted equipment by promoting the promotion and formulation of LTE V2X standard, especially last year's three-span interconnection work.
The whole work of this year's C-V2X working group, on the one hand, promotes the large-scale commercial deployment of LTE V2X, which will be carried out through many interconnected and interoperable standardized applications, especially the operation of many business models, and will also carry out a large-scale network construction and promotion in Wuxi.
In addition, we focus on the V2X vehicle networking of 5G NR, and mainly study its application scenarios, solutions and key technologies.
We have a 5G application team working on industry application requirements, solutions and demonstration application validation. This group has already covered the research work of some needs and solutions including smart grid, public security and new media, electronic information manufacturing, and published some related research results.
As the first blooming Cup last year, this year, under the guidance of the Ministry, the 2nd blooming cup 5G application solicitation contest was held, including regional contest, special contest and campus tour of the contest.
From the perspective of the whole time dimension, since its launch in January, a lot of regional competitions have been carried out, including many campus activities and some special promotional activities. The whole semi-finals and finals will be held in September, and the case collection will be completed by the end of August. At present, we have collected more than 700 entries, and we hope that you can actively participate in this activity during this period.
Finally, we believe that the development of 5G still needs to build a globalized industrial ecology, which is very important. As a member of the 5G Global Conference, the 5G Propulsion Group, together with Japan, Korea, the United States, Europe and Brazil, co-hosts such an exchange event, which will be held in Europe this year and will be promoted in Shanghai in June next year. The theme of the 8th Global 5G Congress will also be 5G Enabling Digital Economy. It is hoped that the industry will continue to participate in the global event next year.
The 5G white paper has always been an important achievement of the promotion group, so many white papers have been published in the vision, concept, architecture and sub-fields of 5G from the very beginning. So at this summit, tomorrow, we will release four 5G white papers, which are based on the management and collaboration of AI intelligent slices on the network side. The second is the bearer network, which is about 5G synchronous networking and architecture. One is the white paper of 5G media industry, the other is the white paper of V2X security technology architecture.
This year enters the 5G commercial first year, but we also think that the 5G industry and the network are a foundation of the whole application development, so in the development process of the 5G industry, we still need to further promote the maturity of the 5G terminal chip, hoping to speed up the extensive application of the independent networking industry after the maturity of China. In terms of industry applications, we hope to play a leading role in leading enterprises, and the industry can actively follow up, especially deepening and excavating the enhancement of some technical capabilities in key areas such as the industrial Internet and car networking, and realizing many new scenarios and new schemes of 5G, especially some new business models, which will help 5G to achieve successful applications. We also hope that 5G commercial will win the future as the theme of this year's summit. I hope to work with the global 5G industry to promote the successful commercial application of 5G in China.
