2017 is the 5G decision of Qualcomm Huawei to compete for the 5G new air interface standard
Last year, Qualcomm and Huawei's 5G coding disputes caused widespread concern. On the other very critical new air interface standard of 5G, Qualcomm and Huawei completed the 5G connection based on the International Mobile Telecommunications Standardization Organization (3GPP) 5G New Air Port (5GNR) standard on the same day.
On February 22, Qualcomm issued a statement announcing the successful completion of its first 5G connection based on the 3GPP 5G new air interface (5G NR) standard. The 5G new air interface is expected to become the global 5G standard.
Subsequently, China's 5G Standards Promotion Group released information that Huawei recently conducted a test environment in Beijing Huairou's field, and took the lead in conducting 3.5GHz 5G new air interface performance testing and interoperability testing with instrument/chip companies.
The two companies are also "doing the best" in the 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 in the mobile communication standard. There are a series of technical standards in the air interface. Coding, modulation, frame structure, filtering, etc.
In the 3G era, the air interface coding technology is CDMA, and the 4G era technology is OFDM. Whose technology is used in the 5G era? 2017 should be the 5G decision year, and the first version of the 3GPP 5G specification is scheduled for release in 2017/2018. At present, the International Organization for Standardization 3GPP is developing a new 5G air interface standard. Next, around the 5G new air interface standard, Qualcomm, Huawei, Ericsson and other giants will have a fight.
An industry insider told reporters that the current global consensus is that the new air interface adopts a unified standard, but in the technical standards of the 5G new air interface, all enterprises continue to submit their own technology patents to 3GPP, which is decided by 3GPP. Which technology.
Two years ago, Huawei launched a high-profile 5G new air interface technology, F-OFDM and SCMA. If it can eventually become the 5G new air interface standard, it will have a greater voice.
Qualcomm said that the first completed 5G connection demonstrated several advanced 3GPP 5G new air interface technologies, including adaptive independent TDD subframes, OFDM-based scalable waveforms to support larger bandwidth, advanced LDPC channel coding and low-based New and flexible design of the delay slot structure.
The standard dispute of mobile communication is the game of the interests of major enterprises. Qualcomm and Huawei have used standard setting to gain greater voice. A deeper layer behind it affects national interests.
On November 18 last year, at the 3GPP RAN1#87 meeting held in Reno, Nevada, USA, the Polar code pushed by China became the short code coding scheme of the control channel in the 5G eMBB scenario; the LDPC code pushed by Qualcomm as the data channel. The coding scheme. Polar selection is regarded as an important progress in China's 5G technology research and standardization. There are many Chinese communication vendors behind Huawei.
