5g has always been a concern, and this is not the release of the 5G standard on December 21, which has aroused everyone's attention. The release of the world's first 5G standard is to make your curiosity multiply, so who will make the 5g standard? What are the 5g standards? This article mainly introduces the relevant information of the 5G standard, let's take a look.
The world's first 5G standard releasedOn December 21, 2017, at the 78th plenary meeting of the International Telecommunication Standards Organization 3GPP RAN, the 5G NR first release was officially announced to be frozen and released, six months ahead of the planned release time.
The release of the 5G NR version is part of the 3GPP Release 15 standard specification. The completion of the first 5G NR standard is an important milestone in achieving the full development of 5G. It will greatly enhance the 3GPP system capabilities and create more for the vertical industry. More opportunities to lay the foundation for the establishment of a globally unified 5G ecosystem.
In the process of formulating 5G standards, Chinese operators and equipment vendors occupy a dominant position. Wang Zhiqin, vice president of China’s Xintong Institute, said that China has always been the first echelon of the global 5G industry and is one of the chief designers of the standard. According to China Mobile, the company submitted more than 1,000 proposals for 3G air interface standardization to 3GPP, totaling more than 1.6 million words.
The first edition of the 5G standard is divided into non-independent networking (Non-Stand Alone, NSA) and independent networking (Standard Alone, SA). As a transitional solution, the non-independent networking is aimed at improving the bandwidth of hotspots, relying on 4G base stations and 4G core networks. Independent networking can realize all the new 5G features, and it is beneficial to play the full capabilities of 5G. It is an industry-recognized 5G target solution.
According to the 3GPP's advancement schedule, the 5G Independent Network (SA) standard will be frozen in June of 2018, and the overall standard will be frozen in the third quarter. The first version of the 5G Global Standard will be formally confirmed. .
It is expected that by 2035, 5G will generate 12.3 trillion US dollars of economic output globally. It is expected that from 2020 to 2035, 5G's contribution to global GDP growth will be equivalent to that of an economy of the same size as India.
Who is the 5g standard (China)In the discussion of the 5G short-code scheme of the just-concluded 3GPP RAN1 87 conference, after painstaking efforts and extremely brutal competition, the Polar Code scheme, which is mainly promoted by China Huawei, became the 5G control channel eMBB scene coding scheme. . This is a remarkable achievement in the history of communication, and this achievement is bound to go down in history.
The discussion of short codes is divided into control channels and data channels. Each company has comprehensively analyzed several candidate codes from the perspectives of performance, implementation complexity, and feasibility. The discussion at the conference was fierce, and almost all companies were involved. Among them, Huawei's proposal supports 59 companies. Even in the early hours of the morning, the participants who were concerned about the coding scheme were still full, and they could only stand by and watch the "war" without smoke.
Coding and modulation are the core content of wireless communication technology. Huawei's own efforts, in the face of the LDPC camp led by US companies, although losing in the competition of long code solutions, but in the key short code, Huawei's optimized Polar code won the final victory, and the Polar Code (Polar Code) solution launched by the company became the eMBB scene coding scheme for 5G control channel. This is a historic moment, which means this. In the future 5G field, this standard is the standard of the world, which means that the world's 5G technology standards will be formulated by Chinese companies.
Looking back on the history of China's communications development, 3G squeezed into the international standard circle, 4G used TD corners to overtake, and 5G tried to lead the world. This is the great change that has taken place in recent years. Through unremitting efforts, Chinese communicators have achieved a series of engineering and technical achievements. Although TD-SCDMA technology is not mature enough, it has made China's communication technology catch up with the world for the first time. With the development of TD-LTE technology, China's communication technology has become one of the mainstream technologies in the world for the first time. However, what needs to be seen is that the core long code coded Turbo code and the short code tail bite convolutional code are not original Chinese technologies.
In terms of 5G promotion, China is recognized as the most active country, and no one. Huawei is the most effective enterprise. The first 5G contribution award was given to Huawei. Huawei made a 5G test network with a download speed of 115Gbps three years ago. Please note that G is not M. Now, the Polar code led by China's Huawei company has finally broken the ceiling. This is not only the return of China's years of careful research in the field of basic communications, but also the portrayal of China's comprehensive strength in the field of communication technology. All the achievements will not be smooth, Polar code faces the strong competition of the US-led LDPC camp, and the long code plan is a few votes. In the short code competition, the further optimized Polar code king returned and won the control channel short code victory.
It is estimated that Qualcomm will be shocked by a cold sweat. We all know that Qualcomm's current strength in the field of wireless communication technology can be said to be too strong, leading the world, especially domestic manufacturers to look at its face, the ugly point is to pay protection fees to Gaotong, who in the end Can we break Qualcomm's monopoly in the field of wireless communication technology?
In fact, it is clear that whoever leads the 5G standard can break Qualcomm's monopoly.
