China News Service Client, Beijing, July 4th (Reporter Wu Tao) On the evening of the 3rd, Beijing time, the International Standards Organization 3GPP announced the freezing of the R16 standard, which marked the completion of the first 5G evolution version standard.
According to reports, the R16 standard not only enhances the function of 5G, but also allows 5G to further enter various industries and promote a new digital eco-industry. It also takes into account factors such as cost, efficiency, and efficiency, so that basic communications investment can play a greater role. Benefits, and further help the digital transformation of the social economy.
The International Standards Organization 3GPP has frozen the first version of 5G R15 in 2018. In the formulation process, R15 strives to produce the "usable" standard at the fastest speed, which meets the basic functions of 5G in many aspects.
The frozen R16 has achieved from "usable" to "easy to use", and has further enhanced the 5G more around the three aspects of "new ability expansion", "existing ability to tap potential" and "operation and maintenance cost reduction and efficiency increase". Good service industry application capabilities have improved the efficiency of 5G.
For example, for industrial Internet applications, new technologies are introduced to support 1 microsecond synchronization accuracy, 0.5-1 millisecond air interface delay, "six nines" reliability and flexible terminal group management, which can achieve end-to-end within 5 milliseconds at the fastest Delay and higher reliability, providing support for industrial-grade time-sensitive.
For Internet of Vehicles applications, it supports V2V (vehicle-to-vehicle) and V2I (vehicle-to-roadside unit) direct communication, through the introduction of multiple communication methods such as multicast and broadcast, as well as optimized perception, scheduling, retransmission, and vehicle-shop connection Quality control and other technologies to achieve V2X support for vehicle formation, semi-automatic driving, epitaxial sensors, remote driving and other richer connected vehicle application scenarios.
For industry applications, a variety of 5G air interface positioning technologies have been introduced, and the positioning accuracy has been improved by more than ten times to reach the meter level. Several basic functions of R15 have been continuously enhanced in R16, which significantly improves the cell-edge spectrum efficiency and handover performance, and makes the terminal more power-efficient.
The reporter was informed that China Mobile continues to play a major role in the R16 standardization, submitting more than 3,000 technical proposals, accounting for more than 30% of the total number of global operator proposals, and leading the completion of 15 technical standards, including wireless aimed at reducing costs and increasing efficiency Data collection and application, service-oriented architecture framework and interface enhancement, remote station interference cancellation for atmospheric waveguide, and high-speed rail performance improvement, etc. (Finish)
