China's 5G R & D is full of spectrum strategic planning yet to be implemented

In a recent period of time, 5G was hot in the circle of friends, and the WeChat public was born with nearly 7000 5G hot texts, and the Baidu index of 5G was more than 10 times more than the highest value of the past year.

HUAWEI, a Chinese company, detonated the 5G's public opinion feast. Its lead PolarCode was adopted by the 3GPP Standard Organization in November 17th as the control channel coding scheme for 5G. Coding and modulation technology is regarded as the crown in the field of wireless communications, and the first time a Chinese company has the right to speak in such a core standard area.


Followed by the following, China Mobile led 5G system system design also formally started standardization, the project will be in the end of 2017 to formulate the "5G system overall architecture and function" and "5G system basic process" two basic standards.


In November 20th, the Ministry of industry and information invited several domestic and foreign operators to hold the second stage specification conference of the 5G technology research and development test, and reaffirmed the vision of "strengthening international cooperation and promoting the formation of a unified global standard for 5G".


The game and compromise of standard


Foreign media rarely reported any 3GPP meetings held in from November 14th to 18th in Reno, us. Even a month ago, the Qualcomm led LDCP code was chosen and failed to cause media attention. A foreign company company told economic reporter on twenty-first Century: "this meeting is not quite different from the past. Although it involves some games, it is more ordinary technical discussion. The most important significance is to push forward the 5G standard process and take a step forward.


In fact, this is the second battle of the 5G coding scheme. In October 14, 2016, the Qualcomm led LDPC code was won by a majority of votes, and the Polar code was adopted as the long block coding scheme for the 5GeMBB scene. At the meeting, 5G's short code scheme was discussed at the 14-18 November meeting, while control signaling and URLLC scenarios, mMTC scenarios, and other scenarios were discussed in the future.


In November 17th, the Polar code was pulled back to a city, and the majority vote was chosen as a short code encoding scheme. Although the Polar code has been born for a relatively short time, it is reported that the Polar code can achieve the 5G rate of 27Gbps and reach the 5G peak rate 20Gbps requirement.


"If we want to unite the global standard organizations to promote unified standards, we must achieve as many interests as possible." 5GNR, a well-known public figure in communications industry, said: "compromise and compromise have always been the philosophy of 3GPP."


GNR, for example, at the beginning of last year's NB-IOT scheme, HUAWEI, high Qualcomm's CIOT scheme was competitive with the NB-LTE scheme proposed by Ericsson and Intel, and in the end 3GPP made a compromise on both sides and proposed a NB-IOT scheme. Under the premise of guaranteeing the equal interests of both sides, 3GPP unified the strength of all enterprises and accelerated the process of NB-IOT.


NB-IOT is regarded as the next blue sea for traditional business entering a growing ceiling. According to MachinaResearch, the global Internet of things Research Institute, the global operator of the Internet of things connected 230 million in 2015, contributing about $7 billion to operators, which will reach $24 billion in 2020. A HUAWEI staff said that by 2020, the proportion of IOT devices connected to the operator network could reach 20%, and the proportion will continue to increase. For companies promoting NB-IOT, it is most important to achieve NB-IOT business as soon as possible.


Today, 5G has adopted the two schemes of LDPC and Polar, and has also balanced the interests of many parties. For enterprises involved in the 5G standard game, accelerating the landing of the global unified 5G standard is the prerequisite for all games.


After the technology lead, after the policy


Since 2014, the global telecommunications industry has been growing slowly, and operators and telecommunications companies hope that 5G will reverse the decline of the telecommunications industry.


Therefore, in the ITU definition of 5G, in addition to the continuation of the eMBB scene of the traditional business, the two major scenes of URLLC and mMTC are planned. The former is devoted to the networking of large-scale Internet of things, while the latter serves the industrial robots and unmanned areas requiring ultra low delay. In fact, this is also a "future" field in the world's scientific and technological community, and the communications industry hopes to bring new revenues through these two scenarios in order to change the model that operators used to rely on user dividends in the past.


Of course, this means that 3GPP needs to introduce more participants. According to the twenty-first Century economic reporter, in the early 5G, the communications industry extended 5G to the leading enterprises in the automotive and industrial fields and failed to attract enough investment. At present, such as general motors and other industry leaders have joined the 3GPP organization, and actively participate in standard formulation, but compared to the traditional communications companies can not enter the mainstream.


Only enough interests can attract the traditional industry to accept 5G, which requires the communication enterprise, 3GPP to define the URLLC, mMTC scene in the future, to the automotive, industrial, medical and other industries to give enough compromise. Moreover, it needs to be pointed out that the automotive and industrial sectors are China's weak links, such as HUAWEI, such as HUAWEI, in the standards of these scenes, not in a favorable position.


Of course, China's telecommunications industry is growing, but it is premature to "dominate 5G". Half a year ago, "the U. S. commerce department sanction", at that time, because the core components of China's communications industry are mainly imported from the United States, communications industry has been pointed to a severe situation. In a HUAWEI network security report, HUAWEI introduced 70% of its products from imports, and 32% from the United States, for example, in 2012, HUAWEI reached $5 billion 720 million from US companies. This situation does not change in the short term.


Today, the US and European governments are not less supportive of 5G than China. In July 2016, the White House announced that it invested $500 million to finance 5G, and attracted nearly 20 companies to build 5G test platforms in 4 cities in the United States. At the same time, FCC (Federal Communications Commission) formally used 24GHz spectrum for 5G, and spectrum resource is the most important resource of wireless communication.


In September 2016, the European Commission announced the "5GforEurope", announcing a complete 5G deployment roadmap by the end of the year, and starting the pre commercial 5G in 2018, and requiring the member countries to select the city to provide 5G services by 2020. In addition, the European Union also explicitly provides frequency spectrum tests before the end of 2016, and determines the spectrum resources such as 6GHz and millimeter wave for 5G before 2017.


Compared with the European Union and the United States, China's R & D work in 5G is not backward. The Ministry of industry and Commerce set up IMT-2020 early and issued 863 major projects. However, although the Ministry of industry and credit has given the promise of "strengthening spectrum co-ordination" and "reserve not less than the spectrum resources of 500MHz", it is regrettable that there is no sign of the strategic planning of 5G spectrum at present. Moreover, China has not yet issued an outline of action, like the United States and the European Union.


It is necessary to point out that the spectrum resource has always been one of the policy problems that plagued the development of China's communications industry, but this problem has always been put on hold in the political game of the telecommunication and radio and TV departments, and there are no signs to be solved at present.
