Hequan, vice dean of Chinese Academy of Engineering: Mastering TD and LTE Rhythm

Editor's note: the 2010 Shanghai World Expo will be held soon, as one of the World Expo's largest scientific and technological highlights, China Mobile is responsible for the construction of the LTE demo network was officially opened yesterday. As the world's newest broadband wireless communication technology system in China, the only core intellectual property rights of the technical standards, LTE will bring what kind of wonderful attention from all walks of life, its hundreds of megabytes of transmission capacity is expected. As the pace of the World Expo is approaching, more and more people outside the industry want to know more about LTE and contact LTE in close proximity.　　To this end, this reporter invited Chinese Academy of Engineering deputy Dean Hequan Academician, Department of Telecommunications Research Institute deputy Dean, LTE Working group leader Cao Shumin to LTE profound interpretation. Hequan: January 16, 1943 was born in Panyu, Guangdong, 1964 graduated from Wuhan University of Posts and Telecommunications, 1999 elected as academician of Chinese Academy of Engineering. Currently deputy Dean of China Academy of Engineering, former deputy Dean and chief Engineer of the Ministry of Telecommunication Science and technology, he is also a deputy director of the National Informatization Advisory Committee, a member of the National 973 Plan expert Advisory Group, a deputy director of the national "863" program Supervision Committee, and a vice chairman of China Communications Association.　　For many years, the ITU-T network Standard Research group has participated in the drafting of technical policy research and the national medium and long term science and technology development planning outline, and participated in the national communication development decision-making. "China Mobile is the world's first LTE network in the LTE test network, which is being built in Shanghai Expo Park. The brilliant appearance of the broadband wireless communication technology with China's independent intellectual property rights has marked a solid step forward in the research of the next generation mobile communication technology, which will have a far-reaching impact on the development and internationalization of LTE industry. Recently, the Chinese Academy of Engineering deputy Dean Hequan in an interview with this reporter said. He stressed that the development of LTE not only embodies the rise of China's power in the global mobile communication map, but also is the important strategic opportunity for China's communication industry to realize the collective breakthrough of independent innovation. "This is the result of years of accumulation of industry, but also the mission entrusted by history." "From the standard leading to the industry leader, LTE is an important opportunity to face the wave of economic globalization, standards have become the core competitiveness of the world's basic elements." An enterprise and even a country, in the fierce international competition only to participate in the formulation of standards in order to seize the commanding heights of the market, grasp the industrial discourse. Once upon a time, China's mobile communications industry due to the lack of international "standards" paid a heavy price, and the proposed TD-SCDMA standard and commercialization finally made our country in the mobile communication field to get rid of controlled situation, have a good beginning, the rise of national independent innovation power for the entire industry injected a strong confidence. As a TD-SCDMA evolution Technology, LTE has realized the inheritance and continuous innovation of its own key technology, while maintaining the coordinated development with the international mainstream LTE technology,As the only standard of TDD in 3GPP, it is not inferior to the development of fdd-lte compared with its technical characteristics and development. In Hequan's view, from Td-scd-ma to LTE, China's communications industry has achieved the synchronized international standards of sustainable development and become one of the leading forces, but independent innovation is not a scientific category of nouns, but should be included in the category of economics, independent innovation only to produce economic and social benefits can be valuable, Therefore, it is the ultimate goal of our country to promote independent innovation to realize the leading from standard to industry. In the process of the industrialization of TD-SCDMA, Chinese enterprises not only play an active role in the operation and manufacture, but also rise in the fields of terminals, chips and meters, some of which are brought up by foreign enterprises.　　It can be said that it is because of TD-SCDMA, a Chinese enterprises to participate in and lead the TD complete communications industry chain began to form, although the strength of the industry chain is still relatively weak. "With the development process of TD-SCDMA Standard, the advantage of LTE will bring an important opportunity for the group breakthrough of Chinese communication industry." "Hequan pointed out that on the one hand, LTE not only has our own key technology, but also in the beginning of the standard set up with international vision to achieve the integration of mainstream technology, so LTE's internationalization prospects are very broad, is expected to be in the global wider range of applications, This will not only attract more global enterprises to push forward the development of LTE industry, but also bring important opportunities for China's communication enterprises to enhance their international competitiveness, and some of the weaker industrial links in China may overtake the corners in the 4G era. On the other hand, TD-SCDMA after 10 years of bumpy to enter the business, and the upfront investment in the funds and support are relatively small, but LTE from the beginning of the country and the industry attaches great importance to the national major science and Technology, a series of support and supporting policies are introduced, domestic and foreign enterprises are very high participation enthusiasm, A group of chips, software and other emerging strategic industries were driven. "LTE is an international standard, China's manufacturing industry can take China-led international standards to go abroad, I am very confident!" "Research and production" close combination, operators should play a leading role Hequan that we can not blindly optimistic about the development of LTE, from standard formation to industrial applications, LTE to achieve market success also faces many challenges, such as LTE chip, intelligent terminals, network optimization technology, Test instruments and business applications.　　In particular, chip, the current LTE chip research and development although attracted many manufacturers to participate, but the chip level and Fddlte chip compared with a certain gap, and this is the key to LTE development. "To meet these challenges, we need the strong support of the government departments, but also need to ' use ' the close combination, especially ' use ' is the key link, so operators should be in TD-lte in the process of industrialization to play an active role in leading. Hequan said that in the early days of TD-SCDMA entering the market, terminals, networks, instrumentation, chips and so there are a lot of imperfect places, then assume the responsibility of the operation of China Mobile has played a very good guiding role, the introduction of special incentive funds to lead the industry chain breakthrough bottlenecks, put forward the "three new three integration" network integration development Ideas, Achieved many innovative results, the network quality is close to the GSM network level, and in the business development has also achieved a great improvement.　　At the same time, in the LTE standardization process, China Mobile to seize the opportunity of technological evolution in time, joint equipment manufacturers, terminals, institutions of higher learning, research institutes and other partners to give full play to their own international influence, for the LTE standards of internationalization and rapid development has played a very important role. "LTE of the industrialization process may also encounter TD-SCDMA encountered or new problems, to solve these problems require the overall breakthrough of the industrial chain, with superior resources and strong strength of the operators should take up the task of driving industry development, which is the operator to promote their own innovation opportunities, It is also the request of the State to the Operation Enterprise. "Grasp the development of TD and LTE as a new generation of mobile communications technology, LTE although the rapid development, but the reporter learned that at present, is still in the technical test phase, the Shanghai World Expo Demo Network will only select a few cities nationwide to carry out small-scale experiments, The advent of sophisticated commercial terminals and large-scale commercial deployments are still quite a long time away.　　Hequan judge, LTE commercial will not be earlier than 2012, even if commercial, will also coexist with TD-SCDMA network for a long time. "Now some of the manufacturers because of the fddlte in the field of leading advantages, so actively promote the Chinese LTE commercialization of accelerated." But the commercialization of LTE cannot be rushed. "As a new communication technology, the commercialization of LTE cannot deviate from the rules of technology, and when it is commercially dependent on a variety of factors, such as the maturity of the technology and the acceptability of the users, it is also important to be fully prepared for the Chinese communications business," Hequan said.　　"Hequan recommended that China Mobile continue to vigorously promote TD-SCDMA development, accumulate more market experience and user experience, lay a good foundation for the development of LTE, at the same time, China's communications industry, manufacturing, terminals, chips, software and other enterprises to significantly accelerate the pace of innovation and development, not with this historical opportunity missed (Su Wen people posts and telecommunications)
