Mobile phone is short of "core" will be in 5 g era change greatly, because China's dominance of 5 g technology standards are likely to become the leading international technical standards.

, chairman of the China Internet association, the IMT - 2020 TuiJinZu consultant WuHeQuan academicians pointed out that in the past China has carried out the 3 g, 4 g technology experiment, but this is the first time before the standards on technology research and development test.

Currently, qualcomm, Intel, haisi, spreadtrum, datang, zte racing to develop 5 g chip technology research, but most of them are still in the process of standardization of 5 g, and ongoing 5 g chips related technical preparation, also did not reach the level of research and development of terminal chip.

However, who can jump start step in the marathon in 5 g, means to be able to beat their, driver's voice technology, in 5 g "core" slack may not be on the road.

5 g chip in the road

5 g already became the various countries' to grab a piece of high science and technology. As in October 2015, the ITU ITU by about 5 g IMT - 2020 road map of development, global competition of 5 g curtain officially opened.

According to the plan of the schedule, the itu will begin in 2017 for 5 g technology solutions, standardization in 2020. Eu METIS, Chinese IMT - 2020 (5 g) TuiJinZu BBS, Japan, South Korea, 5 g ARIB each 5 g research organization are inputs such as study, discuss the vision, requirements, objectives, 5 g capability, key technology, standardization and spectrum, etc.

ShaYue, vice-president of China mobile home, points out that due to the unprecedented Asian countries actively promote, the first 5 g network is likely to appear in Asia, and to promote large-scale 5 g application may also be Asia.

China is one of the most active one. According to reporter understanding, begin as early as 2011, China had the next generation mobile communication system layout, 2013 more launched a special fund for 5 g research funding. In September 2015 to attend the china-eu 5 g joint statement signed strategic cooperation, China had said it would strive to achieve in 2020 5 g commercial network.

And according to the China mobile telecom with South Korea, Japan's NTT DoCoMo, the three fastest pyeongchang city to host the winter games in 2018 will launch 5 g network services.

The ministry's chief engineer zhang said a while ago, 5 g technology research and development of test in our country has launched earlier this year. Technology research and development test key technology including validation, technical scheme and system authentication three phases, will be completed in 2018 and into the next phase, product research and development test.

Chinese information communication of the institute, the IMT - 2020 (5 g) TuiJinZu leader Cao Shumin on January 7, 5 g technology research and development of test launch conference stressed that the 5 g experiment to research and development of standardization and synchronization.

The reporter understands from many mobile phone chip companies, both foreign and domestic chip companies, most of them are still in the process of standardization of 5 g, and ongoing 5 g chips related technical preparation, also did not reach the level of research and development of terminal chip.

This can be from this year's CES at the consumer electronics show a snapshot of a thing or two in the United States. Because 5 g terminal chip also has yet to be developed, Ericsson display terminal 5 g prototype, can only be built by the circuit, so huge.

But this does not mean that mobile phone chip manufacturers are absent 5 g. Although 5 g related technologies and standards development process is unclear, but qualcomm, Intel, haisi, spreadtrum, datang, zte racing to develop 5 g chip technology research. After all, who can jump start step in the marathon in 5 g, it means to be able to beat their, grasp the leading technology.

"5 g never created,"

"5 g won't produce out of thin air." Qualcomm, Qualcomm, senior director of research and development, director of the China r&d center (Hou Jilei, told the China electronic newspaper reporters. He said, from the point of view of the products will be 4 g 5 g evolution, on the 4 g has a strong strength of the manufacturers to be a leader in 5 g. This will be reflected in the ability of system design and multi-mode design ability, which is why in the age of 5 g SoC expertise is so important.

Since 2006 have begun to 5 g prospective research and development, in collaboration with the industry to promote 5 g, participate in important 5 g each demo and test the qualcomm still has the largest chip technology. For a long time, qualcomm are delivered in the form of chips from the base station to the terminal side of the chip to the core network solution of a set of wireless communication technology. Both the standardization of technology, and wireless communication technology research and development of itself, qualcomm has accumulated a lot of technology capital.

Hou Jilei pointed to the reporter, at present the qualcomm technology has been applied to the fourth generation of cellular networks among many, is also to the 5 g technology, including car to car communication, advanced MIMO technology, multi-input multi-output (MIMO) and peer-to-peer network carrier aggregation (peer to peer), etc.

OFDM technology, for example, qualcomm's judgment is 5 g will not experience to the new format conversion, although the system in the past has been from the analog signal to digital signal, from 3 g CDMA into 4 g OFDM, but 5 g will follow OFDM technology. Qualcomm in OFDM chips and technical aspects of professional accumulation, is one of the advantage of the 5 g chip.

In addition, qualcomm that millimeter wave is one of the important ways of acme mobile broadband. In the millimeter wave frequency spectrum, each user can enjoy the 5 ~ 10 gbit/s data service, at the same time provide service users, greatly improve the efficiency of the network throughput and service users. And qualcomm have the experience of the rf chip commercial applications of the millimeter wave frequency spectrum, it will also have very good to the development of qualcomm 5 g chip.

"Relative to the implementation of 5 g chip difficulties at present, mainly concentrated in the high rate of the receiver, low latency, high frequency of rf front end and the corresponding experience of low power consumption, etc., this also is qualcomm research emphasis." Hou Jilei said.

Entered since 2016, the pace of qualcomm 5 g have greater. During the period of 2 months of MWC, qualcomm and Ericsson reached cooperation, joint 5 g technology development and early interoperability testing, 5 g key technology components of early testing and validation, to support the 3 GPP Release 15 specification standardization.

In addition, qualcomm at GTI summit, with China mobile launched 5 g joint innovation center, promote the 5 g candidate technology demonstration, standards, industrial chain building and mature products.

Hou Jilei pointed out that the Release of 15 and 16 projects show that 2020 years ago, 5 g standard will be completed, formal product will also realize the commercial, and qualcomm will launch the corresponding chip in the first place.

The whole Chinese legion

Lack of "core" has been the Chinese industry the deepest pain, and mobile phone short of "core" will be in the age of 5 g change greatly. Is one of the biggest reasons, China's dominance of 5 g technology standard is likely to become the leading international technical standards.

This is the first time in China so early to layout standards and patents. , chairman of the China Internet association, the IMT - 2020 TuiJinZu consultant WuHeQuan academicians pointed out that in the past China has carried out the 3 g, 4 g technology experiment, but this is the first time before the standards on technology research and development test.

Technology research and development and validation of open environment, to participate in the 5 g technology research and development test of Chinese chip companies patent accumulation. And equipment business, led by huawei, zte, the rise of more they brought infinite possibility.

Zte CTO Xu Huijun pointed out: "the communications company who first master 5 g key technology, able to have more say in the standards, also it is possible to win the future."

Into 5 g of huawei in 2009 as an example, according to reporter understanding, huawei has been basically completed most of the May 5 g technology selection, technology research and laboratory verification, the Japanese operators in chengdu opened the world's first multi-user 5 g technology field, in the network architecture and the use of spectrum, hollow technology, such as base stations to achieve a breakthrough, and began to develop 5 g equipment.

Huawei also puts forward the concept of 4.5 G, independent research and development of some of the 5 G core technology applied to the 4 G network in advance, to the smooth evolution of 5 G. At present, huawei in Norway, Germany, Kuwait, Turkey, Canada, Singapore and other countries, the united Arab emirates (uae) deployed 4.5 G of commercial and commercial network.

Can be expected, with the advantage of large platform, huawei will convey the accumulation in the field of communication to the sea. The reporter understands, haisi established 5 g special group has done a lot of terminal chip technology, with the aid of synchronization with huawei's 5 g network equipment advantages, can more quickly to form alignment effect. Standing on the shoulders giants of the sea, there will be the possibility of surpassing qualcomm.

Spreadtrum also unwilling to lag behind. The reporter understands from spreadtrum, spreadtrum have also participated in the national research and development of 5 g, 5 g standards work in the world, was founded in Beijing, Shanghai, Finland has the special research and development team, 5 g in the core technology, system scheme, design carefully the stationing, focusing on the terminal side and the physical layout, the transition to a 5 g terminal chip first echelon member as the goal.

On February 26, spreadtrum technology company with is Germany signed the memorandum of cooperation, common in the process of forming of the technical center in Shanghai, is expected to open in May. In MIMO, broadband, (DPD/VoWiFi testing solutions and 5 g pre-research areas such as close cooperation.

From 2 g era developed with independent intellectual property rights in the first paragraph Asia since cell phone core chip, spreadtrum has been accompanied by China's grow up with the independent communications standards. Can say, in the td-scdma standard for 3 g, 4 g era wealth accumulated by the technology, development of spreadtrum style of 5 g chip.

Mediatek will cooperate with Japan's NTT DoCoMo r&d 5 g, 5 g of mediatek chips is expected in 2018 ready, with chips and Japan's NTT DoCoMo stage in field test.
