Wen / Chen Huiling

A 3GPP technology conference that took place 18 months ago has recently become the focus of much debate in the country. Before that, many people might have known 5G, but probably few really did.

What is more important is that it only emphasizes its own standards, and even wants to dominate them. On the face of it, what looks bright behind it is, in fact,

Lenovo and Huawei say:

These two days, the Internet did not support the Polar code advocated by Huawei in the eMBB control channel coding scheme, called UL Channel Control Code), for Lenovo's November 2016 3GPP. Instead, it supports LDPC coding supported by foreign companies such as Qualcomm, and LDPC has become a data channel coding scheme for eMBB scenarios when it was voted at a previous 3GPP conference. Although in the end the eMBB short code scheme was ultimately won by Polar coding, there were a lot of reports at the time directly using the

Unfortunately, in a very exciting atmosphere at that time, no one really listened to the clarification of HUAWEI. There was no more people to study the process of the continuous evolution of 5G technology and what kind of real relationship would happen to the competitiveness of the future industry.


It is because the original mistake will be wrong, in 18 months now, there are Lenovo did not vote for Huawei many

Finally, compel Lenovo Group can only repeat a statement, and the association's founder Liu Chuanzhi, chairman and CEO Yang Yuanqing, Lenovo holding President Zhu Linan three people issued a joint letter stressed that Lenovo in the 5G standard of the voting process of the practice of no problem, Lenovo senior also with the founder of HUAWEI Ren Zhengfei once Through the dialogue, both sides believe that the practice of the 5G standard voting process in the same year had no problems, and agreed that Chinese enterprises should be united and cannot be provoked by outsiders.

And in this letter issued by the Lenovo's three big heads, the letter also restores the original voting status. It was mentioned in the letter that, at the time of the first round of voting for the 5GeMBB program at the 3GPP conference, the Lenovo chose the LDPC technical scheme based on its own pre technology and patent reserves, but in the second round of voting, it was based on the overall production of the country. The development of industry cooperation has turned to Lenovo's Polar code, which is not much technology accumulation, but is dominated by HUAWEI.

Now that all is said, it should be clear, for the one who is accused of the Negro, and the other who thinks of being blackened, have come out:

But it is worth noting that perhaps between Lenovo and HUAWEI.

5G standard coding competition is only half the battle. URLLC and mMTC still have to contend.

Interestingly, many people now always put the 5G standard coding contention on the mouth, but in fact, in the 3GPP standard setting process, eMBB is the first 5G scenario technical standard to discuss the maturity to a certain stage, so it is taken out to vote, and in addition to eMBB, the 5G scene technical standard in the 3GPP definition. It also includes URLLC and mMTC. These two technical standards have not yet reached enough stage to discuss the technical coding standard. That is to say, in fact, the development of 5G standard coding has not yet been completed in the second half.

In the version of the IMT-2020 specification to define 5G mobile communication technology, the three major application scenarios of 5G are established, that is, the future 5G specifications must be able to meet the requirements of the three different application scenarios respectively, including the enhancement of the operational broadband (enhanced Mobile Broad Band, eMBB), high reliability and low delay Ultra Reliable Low Latency Communication (URLLC), large scale machine communication (massive Machine Type Communication, mMTC).


Among them, the main application of eMMB is the most familiar high speed mobile broadband service, while mMTC is used for large-scale machine interconnect communication, that is, the application scene of the Internet of things, and the two application scenarios have been taken into consideration from the beginning of 4G, and the current LTE-A or NB-IoT is in the future It can be optimized through the continuous evolution of technology functions, and into eMMB and mMTC scenarios of 5G segment.

However, only URLLC is almost a whole new scene, and is so far the biggest variable that has affected all 5G technical standards development discussions, because URLLC is an emerging application that has not appeared in the past, the industrial Internet of things such as automatic driving, or the execution of key tasks, as well as the URLLC application scenario. The functional requirements are very high, for example, the requirements for low delay must be less than 1 milliseconds (1ms) and the actual specification is 0.5 milliseconds, but at the same time, the overall 5G technology must also be considered to be responsible for high transmission rate, high transmission capacity and so on.

In this case, one can imagine that the difficulty of setting the 5G standard is not ordinary.

Many people may not understand the procedures that are included in the 3GPP standard. In general, every discussion of the details of a technical function must be discussed in an individual working group through discussion, then it can be integrated into a larger group of discussions to continue to discuss consensus, and the so-called vote is actually the final result, but the final result is not a broken difference. Because no matter what the final alternative technology is, the options that are finally selected on the table are already a conclusion that will get enough consensus in the process.

But there is not much new progress, including URLLC or mMTC, and the main reason is that, in the discussion of previous technical details, there is a lot of ideas that need to be converged through discussion, and it is not enough to get a consensus to be an option.

Thus, from the process of including 3GPP standard-setting, one thing can be understood: the final formulation of technical standards is not the result of a zero-sum game, but the result of pulling together.

As for whether the technology to support preference is selected as the last technical standard, although some advantages will be achieved, the benefit of this advantage is not as large as that of the outside world.


Therefore, in the process of making the technical standard, it is not likely to have a full - Taking situation. Since it is not a whole take, it is an open competition situation, not only the technical standard stand on whose side, but also more is the strength of the enterprise itself in the follow-up technology development and product research and development.

The standard person doesn't have to win!

Now that we are talking about technical standards, let's look back at Lenovo in the past. The crux of the Huawei incident lies in

This is the case in the history of the communications industry. In the 2000, the WiMAX technology, which was raging to challenge the traditional telecom camp 4G standard, was the same. The 802.16 series of WiMAX technologies, formulated by IEEE, were also included in the 4G technology project, with the same technical status as LTE. Even though WiMAX technology started more than 3 years earlier than LTE, the final result is that WiMAX almost vanished, and LTE is alone in the global 4G situation.

One of the key reasons for this is that the dominant factor in the WiMAX technology standard is :

This kind of mind, in fact, is quickly seen by many people, the communications industry is a relatively conservative industry, a hundred years old Telecom camp has its own mechanism of negotiation and mutual benefit, it is impossible to let an enterprise come from the field of information computer, not to mention that this enterprise is not with everyone. Cooperation, but the desire to dominate this situation.

Because of this, 3GPP led LTE technology started late, but soon after its launch, it did not give WiMAX any chance at all. If we want to comment briefly on the dispute over the technical standards of 4G, perhaps it can be said that this is a war with one enemy and no win at all.

Therefore, looking back on the development of China's thinking on technical standards, in fact, the HUAWEI is a best example from the simple autonomy, self owned and hegemony, to a more pragmatic model of the regular army into the international track and the power to exert influence. Turning over the agenda proposals of several 3GPP working groups, it will find that the number and frequency of HUAWEI's active participation in the proposal have long been comparable to many European and American manufacturers.

In the same way, Lenovo can also vote in the 2016 eMMB coding scheme, and it also represents the cumulative contribution of Lenovo to the long term participation in 3GPP, because in such a standard organization, the right of discourse is not dependent on the size of the voice, not by the size of the company, but by the technical contribution. From this point of view, HUAWEI's right to speak in the 5G technology standard has already had the strength that can not be ignored.

As a matter of fact, many Chinese enterprises, including Huawei, have already begun to change their voice in fighting for international technical standards. They can even say that they are upgrading to another level.

Therefore, it is only a matter of blindly emphasizing its own standards, and even trying to dominate the dominant standards. On the surface, it seems that behind the bright and bright, in fact,

However, for the current domestic development of the overall technology industry, the development of the 5G standard may be only a reminder that deep participation in the formulation of 5G technical standards, or even to make its own proposals a part of the standard, is only a tool, not a purpose. The key to the future competitiveness of 5G is that the speed and depth of landing applications may be more critical.

According to the current plan for the construction of the 5G network in the three major telecommunications operations in China, China will be the world's earliest, the largest to build the true 5G network, and the so-called

The significance of this representation is that China will be the first area in the world to bring 5G technology that really brings application changes into the actual application scenario, and whether it is HUAWEI, ZTE, or even Lenovo, these domestic manufacturers have the opportunity to step up the layout earlier and make the product technology more mature than those in other regions. When telecom operators in other countries begin to think about building networks or promoting 5G applications, Chinese manufacturers may not be the only choice, but they will be the most experienced, most powerful, and most likely best choice, and this is China's 5G technology that will explode in the next 10 years. The real point of opportunity must be grasped.
