ZTE Corporation together with China Mobile Research Institute, the Guangdong Branch of China Mobile, and MediaTek, has completed all the test items of URLLC key technologies in Guangzhou, China.
According to a press release from the international provider of telecommunications, enterprise, and consumer technology solutions for the mobile internet, this is the first URLLC (ultra-reliable low-latency communication) verification on the live network in the industry.
The verification, by virtue of ZTE's end-to-end network equipment and MediaTek's M80 chip platform, was conducted on the commercial 2.6GHz 5G network, including all items like low bit rate MCS/CQI form, R15 mini-slot, slot repetition, and PDCP (packet data convergence protocol) duplication.
The test results show that the air interface delay is reduced by about 20%, and the reliability of the locations with medium and good signal strength is up to 99.999%, it said.
The release pointed out that URLLC is one of the three basic applications of 5G. As a key factor for entering the industry verticals, URLLC accelerates the development of a 5G network. In the future, with wide 5G industrial applications, URLLC can be applied in various scenarios such as AR/VR, smart grid, remote driving, and industrial control, which have special requirements for low-latency and high-reliability connections.
The verification has passed laboratory IODT (Interoperability Development Testing), Beijing Information Port laboratory acceptance, and Guangzhou commercial outfield testing and acceptance, proving that ZTE's base station equipment and technical solutions can meet URLLC requirements for low latency and high reliability in terms of both functionality and performance, said the release.
In addition, through the flexible combination of standard technologies and implementation solutions, the 5G wireless network capability system for URLLC scenarios is formed to meet the differentiated requirements of industries, laying a solid foundation for the applications of URLLC in industry verticals and boosting the rapid development of the digital economy.
