What is 5g international standard to be completed in June this year
4hw.com.cn: according to the news, the first edition of China's 5g international standard will be completed in June 2018. At that time, China will take the lead in 5g. What is the 5g standard? Let's have a look.
The fifth generation mobile phone mobile communication standard, also known as the fifth generation mobile communication technology, foreign language abbreviation: 5g. It is also an extension after 4G and is under study. At present, 5g has not been mentioned in the public specifications or official documents of any telecommunication company or standard setting organization (such as 3GPP, WiMAX forum and ITU-R).
China (Huawei), South Korea (Samsung), Japan and the European Union are all investing considerable resources in developing 5g networks.
On November 15, 2017, the Ministry of industry and information technology issued the notice on matters related to the use of 3300-3600mhz and 4800-5000mhz frequency bands by the fifth generation mobile communication system to determine 5g if spectrum.
According to reports, the first version of 3GPP 5g NSA (non standalone) standard was officially frozen.
According to 3GPP plan, 5g standard is divided into NSA and SA. Among them, 5g NSA networking is a transition scheme, which mainly aims to improve the bandwidth of hot spot area, without independent signaling surface. Relying on 4G base station and core network, it has made faster progress than standard formulation.
This also leads to a discount in 5g performance and capability. In addition, to realize 5g NSA, it is necessary to upgrade the existing 4G network, which has a certain impact on the performance and smooth operation of the existing network.
Therefore, SA independent networking is an industry recognized 5g networking scheme. According to the plan, 3GPP will release SA independent networking scheme in June 2018, when all new features of 5g are expected to be realized.
Although NSA is a transition option, it is also critical. Industry insiders said that the completion of 5g standard NSA program is an important milestone in the 5g standardization process, marking that 5g standard and industrial process have entered the substantial acceleration stage, and 5g commercial has entered the countdown.
