(Economic Observation) What does the R16 freeze of the first evolution standard of 5G mean?
China News Agency, Beijing, July 4th (Reporter Liu Yuying) On the evening of July 3rd, Beijing time, the International Standards Organization 3GPP announced the freezing of the R16 standard, marking the completion of the first evolution of 5G. This means that the 5G standard has moved to all walks of life and will spawn a new digital ecological industry.
Xu Xiaodong, vice chairman of the 3GPP RAN plenary and chief expert of China Mobile, introduced in an interview on the 4th that the previous R15 standard was a basic version of 5G, which solved the enhanced broadband scenario (eMBB) in the three major scenarios of 5G, while the R16 standard Two scenarios were deployed, namely ultra-low latency and highly reliable communication scenario (uRLLC) and mass machine communication scenario (mMTC).
In other words, after the completion of the R16 standard, 5G has expanded from the connection between people to the connection between people and things, the connection between things, and the interconnection of all things becomes possible. Applications such as autonomous driving and industrial Internet will accelerate.
For example, for industrial Internet applications, R16 introduces new technologies to support 1 microsecond synchronization accuracy, 0.5-1 millisecond air interface delay, "six nines" reliability, and flexible terminal group management. The fastest end-to-end within 5 milliseconds End delay and higher reliability, providing support for industrial-grade time-sensitive.
For Internet of Vehicles applications, R16 supports V2V (Vehicle-to-Vehicle) and V2I (Vehicle-to-Roadside Unit) direct connection communication, etc., to realize V2X supports more rich Internet of Vehicles application scenarios such as vehicle formation, semi-automatic driving, epitaxial sensors, and remote driving. .
After more R16 standards for industry applications are frozen, the next step will be to enter the development time of communications manufacturers, and the 5G industrialization for rich scenarios will accelerate.
Sun Tao, vice chairman of the 3GPP SA2 working group and director researcher of China Mobile Research Institute, introduced that during the formulation process, R15 strives to produce the "usable" standard at the fastest speed, which meets the basic functions of 5G in many aspects. R16 allows 5G to achieve from "usable" to "easy to use", taking into account the cost, efficiency and efficiency.
R16 has made tangible improvements in 5G operation, maintenance, cost reduction and efficiency enhancement. A series of technologies will greatly reduce the possibility of manual intervention in network operation and maintenance, network optimization, and effectively reduce labor costs and operation and maintenance costs.
After R16 freezes, 5G phones will also iterate. Sun Tao said that the R16 standard will bring the upgrade of mobile phone chip capabilities, and chip manufacturers will spend about one year to complete the mass production of mobile phone chips under the R16 standard.
It is worth noting that in the R16 standard, Chinese companies have made important contributions. Xu Xiaodong introduced that China Mobile has submitted more than 3,000 manuscripts, accounting for more than 30% of the total number of global operator proposals, led the completion of 15 technical standards, and played a major role. Manuscripts submitted by the three major operators in China account for 40% of global operators.
R16 is the first non-face-to-face meeting in the history of the completion of the technical standards, is the crystallization of the unity and cooperation of the global industry.
“Due to the epidemic, this year’s review meeting was held by telephone conference, so it is necessary to coordinate the time in different time zones in Asia, Europe, and the Americas to facilitate regional experts,” Xu Xiaodong said. Although it is not as efficient as face-to-face meetings, it is still The standard freeze was completed as scheduled.
After R16 is completed, the next step will also evolve to R17. Sun Tao introduced that the original planned freeze time for the R17 standard was March 2021, but now the overall delay has been postponed to June 2021. Due to the epidemic, it may be postponed again. (Finish)
