How to correctly treat the PolarCode solution adopted by the 5G standard

On November 17, US time, the 87th meeting of RAN1 (Wireless Physical Layer) of 3GPP of International Wireless Standardization Organization was held in Las Vegas, USA, to discuss the 5g short code scheme. The three protagonists are the PolarCode scheme promoted by China. Qualcomm mainly promotes the LDPC scheme, and France mainly pushes the Turbo2.0 scheme. The International Mobile Telecommunications Standardization Organization (3GPP) finally finalized the channel coding technology scheme for 5G enhanced mobile broadband scenarios. The Polar code pushed by China becomes the coding scheme of the control channel, and the LDPC code pushed by Qualcomm becomes the coding scheme of the data channel. At the meeting held in Lisbon, Portugal on October 14 this year, the LDPC program was identified as a 5g medium-length code encoding scheme. Since then, the 5g standard has made breakthrough progress in another key link. It is highly probable that the 5g standard will be determined around 2019. The Turbo 2.0 code, which once monopolized the 3G and 4G era codes, was not distributed to the cake because of its few supporters.

In domestic reports, China’s Huawei’s voice in winning with Qualcomm and France’s PK is not small. Some media even appeared that “Chinese standards beat the United States and France.” Some cows blew me, and even the media The columns listed in the Polar Code support company are all domestic companies, including some companies that have no real R&D investment at all. There have also been many companies and universities that have reported their achievements.

Polar Code is not Chinese:

Polar Code was first proposed by Professor Erdal Arikan of the University of Birken in Turkey in 2008. For the first time in theory, the paper rigorously proves that under the binary input symmetric discrete memoryless channel, Polar Code can “reach” Shannon capacity and have Practical channel coding technique for linear complexity coding and decoding capabilities.

The number of companies supporting Huawei's Polar Code solution reached 59, which is the key to winning this solution, which means that the Polar Code solution is the most globally recognized solution. But this is not to say that the program is Chinese or Huawei. It can only be said that China is the main push.

The significance of the Polar Code solution:

1. China's telecommunications companies, represented by Huawei and ZTE, have long-term investment in basic R&D, and have gradually gained more voices in the world. More and more experts from China have held important positions in international organizations in communications.

2. Unlike TD-SCDMA and TD-LTE, Huawei's Polar Code solution has been recognized by the global communication circle. This not only represents the recognition of technology leadership, but more importantly, Huawei and ZTE actively contribute and actively participate. The active and interactive approach has won the support of more and more global communications companies.

3, Polar Code program and LDPC program have been adopted, there is a certain component of mutual compromise, the possibility of launching a unified 5g standard globally is growing, which is the victory of global communications companies.

Be wary of the negative impact of country labels:

In various reports, how is China, how is the United States, and how is France? It seems that establishing a 5g communication standard is a competition between the nations. In fact, 2G said that GSM and CDMA in Europe are still understandable. From 3G, the convergence of communication technologies is inevitable. The three major 3G standards include WCDMA, cdma2000 and TD-SCDMA. CDMA is an obvious evidence, and 4G, there is only one standard in the world, but it mainly includes two schemes supporting FDD and TDD. The proportion of different parts of the two schemes is small. The 5g standard, up to now, the world is still inclined to launch only one standard. Inter-country, inter-enterprise, and technology-to-compromise and mutual integration are far more important than the mutual killing of "you die".

With the addition of national labels, it is likely to receive more exclusion than support. One of the keys to Huawei and ZTE doing better in the international market is to go to China.

Some extreme left views, the winner of the PolarCode program, said that China has won the United States and France, which is likely to be "Huawei Black."
