Spectrum resources are the core resources of mobile communication technology, which will determine the success or failure of operators in the new generation of technology. In the 5G era when high quality spectrum resources are more scarce, spectrum resources will not only affect the development of operators, but also affect the Advancement of the entire industrial chain and even the digital transformation of the industry.
In this regard, at the 2018 China International Information and Communication Exhibition held in Beijing this week, Yanghua, Secretary-General of the TD Industry Alliance, shared his views on the distribution of 5G spectrum.
5G lead is divided into two aspects: technology and market application.
Looking back at the history of mobile communication development in China, China''s mobile communication industry from 1G era blank to 2G era follow, from the 3G era with TD-SCDMA to the 4G era TD-LTE and the international level of simultaneous development. It can be said that through the efforts of the past 20 years, the mobile communication industry chain in our country has accumulated a very strong technical and industrial foundation, which has laid a good foundation and technical strength for the development of our country''s 5G, and has also made it possible for our country to lead in the development of 5G.
In Yanghua''s view, the so-called 5G leadership is mainly divided into two levels: one is technical leadership. For example, Chinese companies should make more contributions to the entire global 5G standardization process; Another leading application in the industry and market should be at the forefront, whether it can take the lead in entering the 5G market application, and through the initial network coverage and the provision of capabilities to promote the market to generate a large number of applications, thus driving the further development of the industry.
It is understood that the proportion of contributions from China in the 5G standardization proposal is as high as 32 %, and it urges the realization of a globally harmonized 5G technical standard. Especially when the 5G SA standard was frozen this year, China achieved a global leadership in the development of the 5G standard. Not only were many standards and structures proposed by Chinese companies, but these standards also became an important part of the 3GPP 5G standard specification. For example, SBA, Polar code and so on.
According to the overall development plan of China''s 5G: At present, it has entered the third phase of the test of China''s 5G technology research and development. Next year, it will be put into commercial operation. By 2020, it will be fully commercial. "With the launch of business in 2020, I believe that there will be more and more applications in various industries based on the improvement of 5G network capabilities, which will further promote the rapid development of the entire industrial chain. " said Yang.
Spectrum allocation is crucial.
Of course, there are still many problems to be solved if you want to achieve the overall leadership of 5G. Among them, how to allocate the spectrum is a key topic that can not be bypassed.
For operators, the frequency and width of 5G is the operator''s strategic point and will determine the position of the 5G starting line. Among them, the level of frequency will determine the investment of the station, and the width of the spectrum will determine the capacity and experience of the 5G network. Therefore, spectrum distribution is very critical, which is also the basis for the future orderly development of the domestic 5G industry.
"If China really wants to achieve 5G leadership, especially in industry and markets, it must first determine the spectrum. Otherwise, industrialization will lose the goal of spectrum. If this is a mistake in decision-making, it may cause great losses to the industrial chain. From a market point of view, Mr Yanghua points out, operators must first determine the frequency band in order to plan how future business will develop and how networks will be built. Therefore, the distribution of spectrum is not only to plan, but also to allocate. To some extent, the distribution of the 5G spectrum is also the next step whether China can truly achieve 5G lead a key factor.
Yanghua made three suggestions for the distribution of the 5G spectrum.
At present, China has divided the spectrum for 5G, but has not yet made specific spectrum distribution to the three major operators. For the distribution of China''s 5G spectrum, Yanghua put forward the following three suggestions:
First, we should first consider the issue of market leadership in the future. China''s 5G market is huge, the size of each industry is also very large, each industry hopes to achieve transformation and upgrade through the development of 5G, so it is very important for us to lead. If we can not achieve leadership, the future may passively adopt some foreign industry technology application programs, in a lagging position. Therefore, the spectrum allocation should not only consider the balance of operators, but also more importantly consider the achievement of our 5G lead goal.
Second, it is necessary to consider the difference in the size of the business and spectrum requirements between operators, rather than adopting an absolute egalitarian distribution method. If the distribution is based on absolute equalitarianism, it may cause some operators to waste spectrum, while others do not have so many spectrum resources, are stretched, and it is difficult to use spectrum to meet different market needs. Therefore, the distribution should not be based on absolute equalitarianism, but should be based on the current situation of the operator''s current market and possible future trends. If there are different directions and plans for the future development of different operators, then a unified spectrum planning should be done based on these, and eventually the spectrum resources can be effectively used instead of being idle or insufficient.
Three, make sure it''s fast. As the 5G has become a key driver of the socio-economic and digital transformation of all countries in the future, all countries are actively deploying and vigorously promoting the development of the 5G. Everyone is actively promoting the development and application of the 5G. Many countries have already allocated 5G spectrum. Therefore, if China thinks too much about the details of the spectrum decision, repeatedly discusses on the side issues, and delays the allocation of time, on the one hand, it will delay the process of industrialization, such as which frequency band the equipment manufacturer makes products for which operators. In terms of guidance, it will lose its goal, and it is difficult for operators to design different combinations of network structures and services according to spectrum planning, resulting in delayed market applications.
"Therefore, in the allocation of spectrum, rapid decision-making is also very important; The absolute average can not be achieved. It is necessary to carry out a rapid decision spectrum distribution plan in a way that both harm each other, so as to promote the development of the industry and promote the operation of the market. Yanghua said: "Because China has a large market and rich industry support, we believe that in the next stage of commercial use, we can also take the lead in innovating 5G applications in many industries to drive the development of the global 5G. It is believed that the future will allow us to take the lead in applications from technology to markets. "
