How do you see the victory of Huawei and Polar Code?
In the communication circle in November, the hottest keyword was "Polar Code". Although more than 95% of the people who eat melons may not understand the meaning of the word, but everyone is holding the attitude of “unclear and fierceâ€, cheering for the state-owned intellectual property rights, and cheering for the Chinese people’s place in the future 5G standard. . 　　
"Huawei crushed Qualcomm and won the 5G era!" The media titles such as "5G Standard China" were arbitrarily forwarded, and the friends circle was smashed. The people who eat melons watched the tide. They wondered: Who let you collect our domestic mobile phones? With so many patent fees from manufacturers, the next 5G era will not suffer this crime!
Although Huawei officially responded, "Standards are not our lead, and we are far from leading this step." The words of the above media are too exaggerated, easy to enemies for Chinese companies, and the extremely difficult 5G standard negotiations are still going on. Killing, fearing adverse effects on subsequent negotiations.
Oh! It turns out that there are so many doorways here, what is the correct posture to understand Huawei and PolarCode victory?
First, let's take a look at the PolarCode code in a foolish way. Suppose a communication scenario, in a noisy restaurant, you want to call the waiter to order, you usually only have two ways: to improve the trick (signal to noise ratio) or repeated greetings (redundant signals). Huawei's leading Polar Code code is to optimize information transmission in such a complex environment. For example, when hundreds of users simultaneously send their own communication and Internet access requirements to the base station, the base station can follow the rules of Polar Code code. Allocate channels for all information. Therefore, the Polar Code code wins only the "control channel coding scheme of the 5G eMBB scene on the short code", which is not the coding mode. From this perspective, Huawei still has a long way to go before it can shake the status of Qualcomm.
Secondly, it is not easy to talk about taking this "control channel coding scheme". The competition of 3G, 4G or 5G standards is related to the global communication voice, in addition to the competition between enterprises, it is also the product of the big country game. According to experts who participated in the discussion of the standard throughout the whole process, the whole process can only be described as “toughâ€. The communication experts of each party hold their own words and demonstrate their respective advantages. Almost every dispute will be discussed until one or two in the morning. . The opponents in front of the Huawei camp are "super-day groups" led by Ericsson, Nokia, Qualcomm, Intel, LG, etc., pushing the LDPC coding method, the difficulty can be imagined. For the European and American tycoons, they still have the heart to remember to maintain the status of cellular communications, and only one path: to seize the 5G core technology and standards.
Moreover, before the Huawei's staged harvest, at the earlier Lisbon meeting, the other party had already smashed and won the "long code program". Huawei, China Mobile, MediaTek, and ZTE camp had two weak votes. The disadvantages are lost. Subsequently, in this very unfavorable situation, the meeting went to the US casino Reno, the Polar Code team led more than 50 companies to re-energize, and finally at 0:45 am local time on November 17, the two camps took a step back. Separate the data and control signaling fields.
"In the process of interest game, there will never be a one-sided fall, and ultimately it can only be balanced with each other." A participating expert brilliantly revealed the deductive law of the 5G standard.
The problem has come, and it has been so devastating. What kind of victory have we won?
Previously, China had owned TDS-CDMA in the 3G era with independent intellectual property rights and TD-LTE in the 4G era, but these two standards are basically only applied domestically and it is difficult to promote it globally. However, this time the channel coding is different, which is a common technology that the global communication industry may use in the future. That is to say, Polar is likely to become a patented technology that all manufacturers cannot circumvent in the 5G era.
In the past two decades, Chinese telecommunications companies have had tremendous equipment manufacturing and commercial capabilities. The greater voice in standards means that Chinese telecommunications companies will have a more obvious first-mover advantage in the industry chain. The data shows that the total number of 5G R&D projects among the major national science and technology projects in 2017 has reached 24, and in the 5G field, Chinese companies obviously want to have more dominance.
Finally, it is worth mentioning that although the polarization code has been recognized in the industry, it has not yet been officially written into the 5G standard, because there is no 5G standard at the moment! According to the 5G standard process, before March 2017, the 3GPP standard for the International Mobile Telecommunications Standardization Organization is still in the research project stage, and the specific implementation timetable will not be discussed until March next year.
At the moment, no one can tell what the exact 5G standard will look like in the future. For Huawei and ZTE, there is still a long game waiting for them. This time, a breakthrough victory in the 5G standard program battle was only a key battle victory.
In the 5G era, the global communications industry will face a major reshuffle. At present, the leading LDPC camps such as Qualcomm and the Huawei-led Polar Code camp can only be said to be evenly matched. Even though Huawei has received the Polar Code signaling control standard, the LDPC camp has added a lot of additional use conditions to it, so this is far from a very satisfactory result for Huawei.
However, this is still a far-reaching transformation, and the final battle of the 5G standard has not yet begun. At that time, eat melons and people, don't forget to call for the country.
