Recently, China Unicom's Research Institute and Guangdong Unicom, in collaboration with ZTE, successfully completed the verification of 5G-A uplink three-carrier aggregation technology in Zhongshan. The test achieved a groundbreaking uplink peak rate of over 1,010 Mbps, setting a new benchmark for China Unicom's uplink capabilities. This milestone marks a significant leap forward in the performance of China Unicom's 5G-A network, injecting fresh momentum into industrial digital transformation.
China Unicom has been advancing its "Intelligent Uplink" technological innovation, leveraging discrete spectrum integration to combine 3.5GHz and 2.1GHz bandwidths into a logically ultra-wide spectrum. This approach not only enhances spectral efficiency but also reduces public resource overhead. The uplink 3CC technology enables efficient multi-band cooperative scheduling. Utilizing ZTE's cutting-edge 5G-A base station equipment and MediaTek's Dimensity platform terminals, the solution successfully addresses the industry's challenge of limited uplink bandwidth. Tests confirmed an uplink peak rate of 1,010 Mbps, significantly boosting both speed and spectrum utilization while ensuring superior coverage and seamless uplink/downlink experiences across all scenarios. This achievement lays a solid technical foundation for the large-scale commercial deployment of 5G-A.
By pushing the limits of uplink speeds, this breakthrough meets the growing demand for high-bandwidth applications such as HD live streaming, real-time large-file uploads, and immersive interactions. Moreover, Guangdong's robust industrial base stands to benefit from 5G-A's enhanced uplink capabilities, enabling real-time 8K ultra-HD video transmission, millisecond-level precision coordination for industrial robots, AR-assisted inspections, drone HD monitoring, and emergency communications. This leading-edge uplink technology will also empower next-generation applications like the metaverse, holographic communication, and industrial internet, providing a robust network foundation for the sustained growth of the digital economy.
