Last year, Qualcomm and HUAWEI 5G coding controversy has caused widespread concern. In 5G, another very crucial new air interface standard, Qualcomm and HUAWEI on the same day has completed the international mobile communications standard organization (3GPP) based on the new 5G air interface (5GNR) standard 5G connection.
February 22nd, Qualcomm first issued a statement announced the successful completion of its first 3GPP based 5G (5G NR) new air interface standard 5G connection, 5G 5G is expected to become the world's new air interface standard.
Subsequently, Chinese 5G group standards to promote the release of information, HUAWEI recently in Beijing, Huairou field test environment, carried out the first 3.5GHz 5G under the new air field performance tests and exchange docking test chip companies / instrument.
The so-called empty, refers to the mobile terminal to the connection agreement between base stations. Is one of the most important standards in mobile communication standards. Empty inside and a series of technical standards. Coding, modulation, frame structure, filtering, etc..
3G era air interface technology for CDMA encoding technology, the era of the 4G for OFDM. 5G era who uses the technology? 2017 should be the year of the 5G decision, the first edition of the 3GPP 5G specification was announced in 2017/2018. At present, the international organization for standardization 3GPP 5G is developing a new standard. The new 5G air interface standard, Qualcomm, HUAWEI, Ericsson and other giants will have a fight.
An industry source told the surging news reporter said that the current global consensus is a new air interface with unified standard, but in the new package of technical standard 5G empty inside, each enterprise to keep their proprietary technology submitted to the 3GPP by 3GPP to determine which technology.
Two years ago, HUAWEI launched a high-profile new 5G air interface technology F-OFDM and SCMA, if 5G will eventually become the new air interface standard, will master more words right.
Qualcomm said, the first to complete the connection of the 5G show a number of advanced 3GPP 5G new air interface technology, including adaptive TDD independent sub frame, based on the OFDM can be extended to support greater waveform bandwidth, LDPC channel encoding and low delay based on advanced new flexible design of slot structure.
Mobile communication standard is the conflict of interests game companies, such as HUAWEI, Qualcomm with standard to strive for greater voice. Behind it a deeper level will affect the national interests.
