Release Time:2024-04-19
  • ZTE, in collaboration with China Mobile's Zhejiang Branch and Qualcomm Technologies, achieves a groundbreaking milestone in 5.4Gbps peak data rates through the industry's first end-to-end field test of 3CC CA and 1024QAM in Jiaxing
  • China Mobile's Zhejiang Branch leverages its high-quality commercial 5G network to gradually implement 5G-A air interface enhancement technologies, aiming to expand the information highway and meet the requirements of emerging services such as VR smart experiences and ultra-high-definition live broadcasting


Shenzhen, China, 19 April 2024 – ZTE Corporation (0763.HK / 000063.SZ), a global leading provider of information and communication technology solutions, has collaborated with China Mobile's Zhejiang Branch and Qualcomm Technologies, Inc. to achieve a groundbreaking milestone in 5.4Gbps peak data rates. Through the industry's first end-to-end field test of 3CC CA (three Carrier Component Carrier Aggregation) combined with 1024QAM (1024-state Quadrature Amplitude Modulation) in Jiaxing, the test showcased a single-user downlink peak rate surpassing 5.4Gbps. This achievement represents a significant boost in network capability and user experience.


This validation harnessed new 5G-A features to fully unlock the spectrum potential of 5G commercial networks, thereby enhancing network capabilities and user experience. Furthermore, it showcased the efficacy of 5G-A technology in fostering rapid and efficient collaboration across various segments of the industry chain, including system products, commercial chips, and terminals. This demonstration provides an important reference point for accelerating the commercialization of 5G-A.

As one of the "5G-Advanced Dual-Chain Integration Innovation Demonstration Bases," China Mobile Zhejiang Branch is leveraging its high-quality commercial 5G network to gradually implement 5G-A air interface enhancement technologies. The aim is to expand the information highway and fully cater to the demanding requirements of emerging services such as VR smart experiences, ultra-high-definition live broadcasting, and glasses-free 3D.


DL peak data rate enhanced with 3CC CA & 1024QAM


Since 2024, China Mobile's Zhejiang Branch, in close cooperation with ZTE and Qualcomm Technologies has conducted the world's first end-to-end commercial verification of downlink 3CC CA with 1024QAM in Jiaxing with the total bandwidth of 260MHz on 2.6GHz and 4.9GHz. 1024QAM, a higher-order modulation technology defined in Release 17, can transmit 10 bits of data in a single symbol and can be used in conjunction with 3CC CA, improving peak data rate and spectral efficiency by 25% over 256QAM in the same bandwidth.


The verification utilized ZTE's commercial 5G network equipment and test device powered by the world's first 5G Advanced-ready modem and RF system, Qualcomm Technologies' Snapdragon® X75. The field test results showed that the combination of these two 5G-A features can achieve a single user downlink data rate of over 5.4Gbps.
