There are many misinformation and rumors circulating on the Internet about the voting process of the 3GP5G meeting. Lenovo hereby explains the brief facts of the two meetings to the public to set the record straight.
At the #86bis meeting in Lisbon, because many companies opposed every proposal, all the proposals could not be passed intact. According to the working principle of 3GPP, the chairman of the venue can decide the similarities (that is, the parts that are not opposed) in all proposals as the final resolution. At this meeting, all participating companies (including China Company) have no objection to the use of LDPC for data channel long codes, but their opinions on data channel short codes are still different, so the meeting finally reached a resolution to use LDPC for data channel long codes.
At Lisbon #86bis meeting, Lenovo and Motorola Mobile supported the adoption of LDPC as the only coding scheme of eMBB data channel dominated by Samsung (instead of Qualcomm for network transmission) by virtue of their own technology and patent reserves. However, Lenovo's position did not play a decisive role in the outcome of the meeting. The two votes of Lenovo and Motorola Mobile have no substantial influence on the failure of Polar code in data channel length code. Because the working mode of 3GPP is to realize * * * knowledge. The only requirement for the proposal to be passed is that no company opposes it, not how many companies agree.
At the #87 conference held in Reno, USA, as stated in the previous statement, Lenovo gave Polar code full support. We voted in favor of the scheme that Polar code is used for data channel short code and Polar code is used for control channel.
Although channel coding is an important part of the development of 5G, the contest of 5G has just begun. Lenovo actively participated in the formulation of the 5G standard and, as always, resolutely supported the development of 5G technology and industry in China.
