5G commercial is necessary and urgent in 2020
On the one hand, the United States, Japan, South Korea and Europe are all striving to lead 5G, and global competition is intensifying.
The United States rushed to deploy 5G high-band, trying to maintain the dominant position of Internet innovation and development. Verizon is the first to release the 5G HF wireless standard, initially used for fixed access, and plans to launch commercial deployment in 2017. The FCC delineated about 11 GHz of high-frequency spectrum above 28 GHz, and the Obama administration announced that it will invest $400 million to support 5G wireless technology development and network testing.
Japan maintains its advantages in the 4G era and consolidates its industrial advantages in the fields of robots/AR/VR. Japan plans to deploy a 4.5GHz 5G commercial system before the 2020 Tokyo Olympics to provide hot coverage and support the Tokyo Olympics. NTT docomo is organizing more than a dozen mainstream companies to carry out 5G trials. South Korea upgrades its network infrastructure through 5G to serve its "innovative economy."
South Korea will launch a 5G pre-commercial trial in early 2018 to support the PyeongChang Winter Olympics. KT announced that it will provide the world's first commercial 5G mobile network in 2019, one year ahead of the planned 2020.
The EU is trying to re-establish the leading position in the communications industry to help the development of the "digital economy"; to define the 5G pre-frequency of 700MHz/3.4~3.8GHz; to start the prototype test in 2017 and the 5G pre-commercial test in 2018, depending on the 5GPPP project, around 2020 Implement commercial deployment.
On the other hand, the rapid development of 4G has stimulated a surge in mobile data consumption. The data traffic has increased spurt, which has led to the continuous improvement of mobile broadband capabilities.
According to the 4G user data growth forecast, China Mobile's existing spectrum (including TDD and FDD) will be difficult to meet the business needs of hotspots by 2019, so more new frequencies and technologies are needed. It is estimated that China's mobile data traffic will increase by 600 times from 2010 to 2020, and will increase by more than 40,000 times from 2010 to 2030.
The new service growth puts higher requirements on network capabilities. For example, the user experience rate requirements of high-definition video services such as AR/VR, 4K, and naked-eye 3D continue to increase, and will reach the Gbit/s level.
The combination of mobile communications and vertical industries creates new demands and opens up new market opportunities. China Mobile will fully implement the big connection strategy when the era of the Internet of Everything comes. On the basis of the advantages of existing users, we will continue to expand the breadth and depth of connectivity and focus on making large connections. By 2020, the number of connections will be “doubled†compared to 2015.
In addition, China Mobile proposes that the development of cellular networks needs to meet the needs of low-latency, high-reliability services for vertical industries. The current informationization of industrial control, smart grid, autonomous driving, telemedicine and other industries has attracted much attention, but this has brought new challenges to the operator network: air interface delay is less than 1ms, end-to-end delay is reduced to ms Level and network reliability is close to 100%.
Technical solution verification is a key part and will do its best
China's 5G technology research and development entered a critical period. The second phase of testing is mainly for 5G standard solution verification, which is the key to ensuring the quality and timely completion of 5G standards. At the same time, part of the interoperability test is carried out to promote the chip industry to start industrial R&D as soon as possible (Table 1).
Table 1 China 5G test plan
China Mobile fully supports the technology research and development test to ensure that the foundation is laid. In the key technology verification phase, China Mobile has actively contributed to the successful completion of the key technical verification work of the IMT-2020 promotion team: participated in the compilation of 6 test specifications, participated in 7 manufacturers, and 21 key technology tests. China Mobile participated in the testing work for 14 months and invested in many technical backbones.
In terms of technical solutions and system test verification, Huang Yuhong said that China Mobile can take the lead in undertaking some projects, such as large-scale antennas for 5G typical operation scenarios. China Mobile will take advantage of its operations, support norm-setting, and contribute to network experience and participate in field testing. In terms of international cooperation, China Mobile relies on NGMN and GTI2.0 to widely gather information on international operators and share test progress and test results. In terms of standard setting, China Mobile will fully support the test results and conclusions, and jointly promote the formulation of 5G standards around national strategies and experimental objectives.
In short, China Mobile will take advantage of its network operations and fully support the second and third phase of the technology research and development test.
Business preparation tasks are heavy, and we are only rushing to advance
China Mobile is actively promoting the development of 5G. Huang Yuhong said that in terms of technological innovation, China Mobile is promoting pilot 3D-MIMO, software-defined air interface, user-centric network and "three cloud one layer" network architecture.
In terms of standard leadership, China Mobile took the lead in 3GPP 5G scenarios and requirements projects, 3GPP 5G network architecture projects and 3GPP wireless intelligent network research projects. China Mobile experts served as vice chairman of ITU 5G focus group and vice president of 3GPP RAN2.
In terms of industrial research, China Mobile has carried out 3.5GHz prototype development and verification, high-frequency communication prototype development and testing, and 5G system concept verification. China Mobile is also actively preparing for 2020 commercialization under the overall planning of the national 5G trial.
In terms of joint innovation, China Mobile has established a 5G joint innovation center and led the international organization GTI 2.0, actively participating in the innovation of ITU, GSMA and NGMN.
At the same time, as a commercial operation company, on the basis of the overall government plan, China Mobile carried out the preparation test for commercialization, and prepared for the commercial product planning in advance on the basis of actively participating in the overall technical verification of the government organization.
China Mobile also relies on the NGMN 5G test to promote cooperation between international operators. China Mobile and DT (Deutsche Telekom) jointly lead NGMN PoC to promote 5G industrialization for 3GPP R15 standards; advocate global unified standards, gather operator resources, reduce industry overhead, and avoid industrial fragmentation.
In addition, China Mobile relies on GTI 2.0 to condense global industrial resources and break through industrial bottlenecks. Since the future 5G spectrum needs to be divided into continuous large blocks of more than 100MHz or even 500MHz, TDD technology will play a more important role in the future 5G.
GTI 2.0 will continue to promote the global development and commercialization of 4G TD-LTE, while continuing to promote the evolution of TDD technology and play a more important role in the 5G era, continuously enhance the international influence of China's industry, promote the development of 5G, and build a win-win situation for integration and innovation. Ecology.
According to reports, GTI 1.0 (2011~2015) successfully helped China to lead the global development of TD-LTE. GTI 2.0 (2016~2020) will help China's industry lead the development of 5G and promote China's innovation to go global. China Mobile focuses on the four major areas of 4G evolution and 5G integration innovation, focusing on systems below 6 GHz, promoting the evolution of TDD technology, the development of 5G industry and cross-industry innovation.
Facing the future, in order to meet the new opportunities of integration and innovation brought about by the “Internet of Everything†in the 5G era, China Mobile is actively promoting the development of 5G industry with the goal of commercialization in 2020. It is reported that China Mobile has launched 51 partners in the “5G Joint Innovation Center†launched in February this year. Currently, 30 joint innovation projects have been launched relying on the open laboratory.
“China Mobile plans to rely on the 5G Joint Innovation Center to promote cross-industry integration and innovation, including promoting the maturity of basic communication capabilities, building an open and win-win integration ecosystem and incubating and integrating innovative applications and products.†Huang Yuhong said.
