Lenovo then announced the voting at two 3GPP 5G meetings, hoping to correct the situation. According to Lenovo's description, at the #86bis conference, Lenovo supported the Samsung led unique encoding scheme for eMBB data channels, which did not support Polar codes, but the negative vote did not have any impact on the final results; at the #87 meeting, Lenovo gave Polar code its full support.
Lenovo said that at the #86bis conference in Lisbon, none of the proposals could be passed unaltered because there were many corporate objections to each proposal. In accordance with 3GPP's working principles, the chairman of the conference can decide on all common points of the proposal (that is, the unopposed part) as final decisions. As at this meeting, all the participating companies (including Chinese companies) had no objection to the use of LDPC for data channel length codes, and opinions on short data channel codes were still at loggerheads. So the meeting finally reached a resolution on LDPC for data channel length code.
2) therefore, at the #86bis conference in Lisbon, Lenovo and Motorola Mobility, for reasons of their own technology and patent reserves, supported the Samsung (not the Internet-based Qualcomm)-led unique coding scheme for the adoption of LDPC as the eMBB data channel. But Lenovo's comments did not play a decisive role in the outcome of the meeting, and two votes from Lenovo and Motorola Mobility had no real impact on the Polar code's loss in data signal length codes. Because the way 3GPP works is to achieve consensus. The only requirement for a proposal to pass is that no company objects, not how many companies agree.
But at the #87 conference in Reno, Lenovo gave Polar code its full support, as previously stated. Both Polar codes for data channel short codes and Polar codes for control channels were voted in favour.
Lenovo emphasized that 5G's right to speak is the number of core patents that were eventually approved. 5G technology, including patents in Polar codes and LDPC codes, is the result of technology integration of several companies. You have me and I have you. Lenovo is delighted that Polar code has finally become part of the 5G standard.
Although channel coding is an important part of the development of 5G, the battle of 5G has just begun. Lenovo actively participated in the formulation of the 5G standard, and as always, strongly supported the development of 5G technology and industry in China.
Therefore, Lenovo will retain the right to take legal action against any distorted reports, malicious attacks and misleading reports and comments to the public.
For this incident, Liu Chuanzhi also can not help but make a statement, saying that Lenovo's voting principle is no problem, there is no problem in implementation. Ren Zhengfei also said that Lenovo did not have any problems in the voting process of the 5G standard, and expressed gratitude for Lenovo's support for HUAWEI.
