Today (January 9th) morning, the annual National Science and Technology Awards Conference will be held in the Great Hall of the People. The conference announced the results of the 2016 National Science and Technology Award, the National Natural Science Award, the National Technology Invention Award, the National Science and Technology Progress Award and the International Science and Technology Cooperation Award of the People's Republic of China. Among them, Huawei's "Tenth Generation Mobile Communication System (TD-LTE) Key Technology and Application" project won the National Science and Technology Progress Award.
In this project, the main completed units include: China Mobile Communications Corporation, Institute of Telecommunications, Ministry of Industry and Information Technology, Institute of Telecommunications Science and Technology, Huawei Technologies Co., Ltd.......
What is TD-LTE?
LTE, TIme Division Long Term EvoluTIon, is a global standard developed by the 3GPP organization based on OFDMA technology, including FDD and TDD modes for paired spectrum and unpaired spectrum. LTE-TDD, also known as TD-LTE in China.
As an important opportunity for the transformation period of the communication industry, TD-LTE mainly includes three major features: First, it contains a large number of Chinese patents, which is dominated by China, and has received extensive international support and become an international standard. Second, the Internet speed is fast and can be achieved. Tens of times of TD-SCDMA technology makes ubiquitous high-speed Internet access possible. Third, the industry is developing at a fast pace and is basically synchronized with other international mobile broadband technologies, representing the most advanced level of the mobile communications industry in the world today.
Therefore, in the whole development process of TD-LTE, despite many problems such as immature network, it has provided a lot of support at the national level, including the Ministry of Industry and Information Technology to set up a TD-LTE working group to lead the organization and work. A very famous working method is called 2*2, that is, two network manufacturers combined with two terminal chip manufacturers to do cross-validation, which quickly promoted the consistency of standard understanding and the maturity of the terminal.
Why did TD-LTE win this award?
"The key technologies and applications of the fourth generation mobile communication system (TD-LTE)" was selected for the final special award, mainly in the fourth generation of mobile communication TD-LTE standardization, research and development industrialization, scale commercialization achieved a series of International leading innovation.
The key technological innovations include: through the breakthrough of key core technologies such as TD-LTE innovative frame structure design and smart antenna technology breakthrough, forming the core of TD-LTE standard; designing TD-LTE exclusive frame structure, realizing LTE FDD fusion and taking into account TD- The innovative frame structure of SCDMA and the maximum realization of TDD/FDD fusion; invented UpPTS uplink interference detection technology and TDD-specific interference cancellation technology such as dynamic AGC and local frequency adjustment; invented Ir interface compression technology, bundle interface and Multi-band independent ESC and other efficient and rapid deployment technologies; overcome multi-mode multi-band terminal chip design and integrated circuit development technology bottlenecks, break through the weak links of terminals, instruments and other industries, establish a complete test system; realize RF chip optimization architecture based on independent receiving channels Terminal chip design architecture scheme for high-integration RF front-end modularization; for the serious problem of internal mutual interference, invented interference cancellation and evasion techniques such as multiple receive channels and built-in multiple VCO circuits; established a complete TD-LTE test system, developed Testing special technology, developing series of instrumentation, design quality assessment method Construction of public research test verification platform.
As of the end of November last year, China Mobile has built 1.46 million 4G base stations, covering a population of more than 1.3 billion, achieving continuous coverage of townships and above and administrative village hotspot coverage; 4G users reaching 510 million, with nearly 70% (69%) of China's 4G Users, there are 1 China Mobile user for every 3 4G users in the world.
