The 5G standard will form the first version by 2018. In order to meet the future development goal of 5G "information from heart to touch everything", the current information and communication industry has shown great enthusiasm for 5G technology research and development, and the communication equipment enterprises are also targeting 5G key Technology to increase innovation, there have been some revolutionary technology, and is likely to be the basis for the future of mobile communications networks. The 5G standard that promotes unification basically becomes the industry consensus. In this global "technology pageant selection," innovation and integration, game and compromise will flow through from beginning to end.
ZTE to create tag technology
Recently, the first Global 5G Conference co-hosted by the IMT-2020 (5G) Propulsion Team and the EU's 5G PPP, Korea's 5G Forum, Japan's 5GMF and US 5G Americas was held in Beijing. ZTE Chief Scientist delivered a speech entitled "Commit to Global 5G Ecosystem" to Dr. Kirkland at the conference. For the first time, he proposed new multiple access and waveform technologies including MUSA (multi-user shared access), FB-OFDM OFDM), UAI (unified air interface), Massive MIMO and other technologies, and calls for joint development with the industry to promote the healthy development of 5G.
ZTE label with revolutionary technology
ZTE will put forward this multiple-access technology MUSA, new waveform technology FB-OFDM, including the previously proposed LDPC encoding technology as ZTE's tag technology.
Multiple access and waveform technology is the cornerstone of wireless communications standards, high technical threshold. In an interview with China Electronics News, InterIagle said that MUSA, a multiple-access technology proposed by ZTE, is revolutionary with respect to 4G and is implemented using simple complex multivariate short codes in non-orthogonal networks. Access to the network, while also bringing great benefits to the network also has great complexity, the huge benefits reflected in: on the basis of the user can increase 3 to 6 times, which will significantly increase the number of Internet users connected And efficiency. FB-OFDM through a simple Poly-phase filter, subcarrier-by-subcarrier filtering to enhance the out-of-band rejection of more than 20dB.
"At the same time, we have greatly simplified the computational complexity." To Eagle International, "The biggest feature of our three proposals is simplification, such as our proposed sub-carrier filtering with 1,200 sub-carriers, which if not simplified The amount of computation is 1200 times that of a subcarrier, and now we turn 1200 operations into one step with a windowing technique, enabling us to achieve the best performance at a fraction of the cost. "
"In accordance with the general law of complexity considerations are in the late stages of the standard, but often found until the operation is particularly complicated, there is no way to change, such as high power consumption such problems will arise, we have encountered such a good performance But very complicated theories, which often can only be a prototype and encounter many difficulties in industrialization. "To Yingjiao," The reason why we took complexity into consideration from the outset is that the company's architecture As a result of the decision, ZTE 5G's standards, products and operations are a single line. Therefore, we are considering how to implement the products while putting forward the standards. Therefore, based on this feature, our company's 5G proposals are also emphasized in 3GPP. "
According to reports, after long-term accumulation of technology, ZTE has become the industry's few manufacturers have the ability to complete a 5G proposal. In 3GPP, the world's most important 5G standardization organization, ZTE submitted hundreds of proposals in core technologies such as Novel Numerology, Self contained Frame Structure, FB-OFDM waveform, LDPC coding, MUSA and NG Core Proposal. In addition to the MUSA and FB-OFDM technologies mentioned above, ZTE is the first to implement 4G-based terminals on Massive MIMO, and is currently in commercial deployment and at the forefront of the industry.
Appeal to jointly promote the 5G healthy development
ZTE is an active participant in the formulation of the 5G standard. According to the introduction, ZTE has now joined more than 40 standardization organizations, alliances and forums, and is an international standard organization / industry such as ITU, 3GPP, IEEE, NGMN and Japan 5GMF Alliance member. As a core member of the IMT-2020 (5G) propulsion team, ZTE led the research on more than 30% of the topics: serving as a research group on the three core issues of IMT-2020 IEEE Team Leader, Network Technology Team Leader, and Transmission Technology Group long.
In the 5G area, ZTE has deep cooperation with many customers both at home and abroad on application requirements, scenario studies, new business applications and network architecture innovations, and has established long-term cooperation with China Mobile, T-Mobile, Softbank of Japan, KT of South Korea, Malaysia U Mobile and other operators signed a 5G strategic cooperation agreement. In May 2016, ZTE was fully involved in the large-scale 5G system test of the IMT-2020 (5G) propulsion team. The first batch of single-point technology verification was completed in the same month, with Massive MIMO large-scale antenna technology reaching more than four times Throughput rate. In addition, ZTE is the first manufacturer to complete high-frequency testing, reaching throughput of 10G and above.
As a core member of IMT-2020 (5G) propulsion group, ZTE urges the industry to work together to promote the sound development of 5G and avoid the fragmentation of the 5G standard. To the eagles said: "5G development is very hot, some countries and regions want to be the first to think faster, and different operators or different countries understand the use of 5G is not the same, will eventually lead to the collapse of the standard, which for the entire industry So I hope everyone can focus on a standard organization to form a standard together. "In order to avoid the fragmentation of the standard, the International Eagle believes that in the early stages of the development of the 5G 5G application requirements identified, the The number of Internet of Things, network latency and other indicators to be further determined.
Qualcomm comprehensive technical layout
As the largest terminal chip supplier, Qualcomm favors and supports the formation of a globally unified 5G standard, although this requires significant industry investment in human, financial and material resources. Edward Tiedemann, Ph.D., senior vice president of Qualcomm R & D, told China Electronics News in an interview that the most important task now for the 3GPP organization is how to choose from various proposals the most suitable for the global deployment in the 5G era Core Technology.
Multi-technology field layout
Edward said that many people think Qualcomm is a leading company in the field of cellular communications and air interface technology, but in fact more than that; Qualcomm in the entire wireless technology has a very deep accumulation of technology, such as in the WiFi technology standard 802.11ax and Bluetooth Technically all providers, etc .; in LTE, LAA (LTE Assisted Authorized Access) technology, unlicensed spectrum LTE technology, MultiFire technology, terminal to terminal through
