The dispute between Qualcomm and Huawei in 5G coding in 2016 has caused widespread concern. On another very important new air interface standard for 5G, Qualcomm and Huawei completed the 5G connection based on the work of the International Mobile Telecommunications Standardization Organization (3GPP) 5G New Air Interface (5GNR) standard.
On February 22, 2017, Qualcomm first issued a statement announcing the successful completion of its first 5G connection based on the 3GPP 5G New Air Interface (5G NR) standard work, which is expected to become the global 5G standard.
Subsequently, the China 5G Standards Promotion Group issued a message saying that in the Huairou field test environment in Beijing, Huawei was the first to carry out field performance tests under the 3.5GHz 5G new air interface and interoperability and docking tests with instrument / chip companies.
The two companies are also "uncompromising" in 5G new air interface technology.
The so-called air interface refers to the connection protocol between the mobile terminal and the base station. It is a vital standard among mobile communication standards. There are a series of technical standards in the air interface. Coding, modulation, frame structure, filtering, etc.
The air interface coding technology in the 3G era is CDMA, and the technology in the 4G era is OFDM. Whose technology is used in the 5G era? 2017 should be the year of 5G decision, and the first version of the 3GPP 5G specification is planned to be announced in 2017/2018. At present, the International Organization for Standardization 3GPP is developing 5G new air interface standards. Next, around the 5G new air interface standards, Qualcomm, Huawei, Ericsson and other giants will certainly have some competition.
An industry insider told the surging news reporter that the current global consensus is that the new air interface adopts a unified standard, but in the 5G new air interface package of technical standards, companies continue to submit their own technical patents to 3GPP, and 3GPP will decide the final adoption Which technology.
In 2015, Huawei launched high-profile 5G new air interface technologies F-OFDM and SCMA. If it can eventually become a 5G new air interface standard, it will have a greater say.
Qualcomm said that the first completed 5G connection demonstrated a number of advanced 3GPP 5G new air interface technologies, including adaptive independent TDD subframes, OFDM-based scalable waveforms to support greater bandwidth, advanced LDPC channel coding, and low-based New and flexible design of the delay slot structure.
The battle for the standards of mobile communications is a game of the interests of major companies. Qualcomm, Huawei, etc. rely on the formulation of standards to fight for a greater voice. Deeper behind it affects national interests.
On November 18, 2016, at the 3GPP RAN1 # 87 meeting in Reno, Nevada, China, the Polar code promoted by China became the short code coding scheme for the control channel in 5G eMBB scenarios; the LDPC code promoted by Qualcomm was used as data Channel coding scheme. Polar's selection is regarded as China's important progress in 5G technology research and standardization, and many Chinese communication manufacturers stand behind Huawei.
