[Shanghai, China, June 27, 2019] During MWC19 Shanghai, China Telecom and Huawei jointly release the 5G Super Uplink Joint Technology Innovation solution. A large number of new 5G services emerge in the new 2B/2C blue ocean markets, posing higher requirements on the uplink rate and latency. The 5G Super Uplink solution proposes the innovative networking technology featuring TDD/FDD coordination, high-band/low-band complementation, and time/frequency domain aggregation, which achieves an unprecedented uplink rate of 5G networks and reduces latency over the air interface. This solution truly redefined 5G networks based on industry requirements.

At the "Hello 5G Encouraging the Future" 5G Innovation Cooperation Conference held in April this year, China Telecom formulated the networking strategy that depends on the standalone (SA) networking and applies three SA features of URLLC, eMBB, and eMTC to meet 2B/2C requirements. China Telecom has extensively explored 5G applications in vertical industries such as government affairs, transportation, ecosystem, party building, healthcare, tourism, policing, Internet of Vehicles (IoV), education, and manufacturing. In the future 2B/2C ecosystem, large bandwidth and low latency are the focus of services. For example, the 4K HD video backhaul will give rise to the boom of new media, Internet celebrity live broadcast, and other services, bringing immersive experience to the audience. Drone services, unmanned driving, and telemedicine have higher requirements on the uplink rate and network latency.
The 5G Super Uplink solution proposed by China Telecom and Huawei implements the time-frequency domain aggregation of TDD and FDD in the uplink frequency band. Therefore, the solution can increase uplink spectrum resources of NR, boost the uplink capability of the 5G network, reduce latency, and improve the utilization rate of the uplink spectrum of 2.1 GHz/1.8 GHz. At the launch event, the Proof of Concept (PoC) of "Super Uplink" was demonstrated. The test results showed that the experienced uplink rate of 5G UEs in the cell center was increased by 20% to 60%, the experienced uplink rate of 5G UEs at the cell edge was increased to 2 to 4 times, the air interface latency was reduced by about 30%, and the URLLC services were enabled. Huawei Balong 5000 chipset, customer-premises equipment (CPE), and Mate 20 X were also displayed at the event. Super Uplink is supported from end to end by Huawei 5G technologies.
Liu Guiqing, executive vice president of China Telecom Group Co., Ltd., said: "The five ecosystems extend to 5G and become the important engine for China Telecom's continuous growth. China Telecom adheres to the philosophy of "Customer First, Attentive Service", insists on formulating standards first and leading technology development, and pioneers the practice of 5G network innovation. To provide better 5G experience, optimize customers' service awareness, and enhance differentiated competitiveness in the market, China Telecom cooperates with Huawei to propose the innovative 5G networking technology featuring TDD/FDD coordination, high-band/low-band complementation, and time/frequency domain aggregation. This solution aims to further improve the uplink data capability and reduce latency, providing better development space for vertical industry applications. China Telecom will work with industry partners to seek the optimal network experience solution and promote the prosperity of the industry."
Ryan Ding, executive director, CEO of the Carrier BG of Huawei Technologies Co., Ltd., commented: "5G not only changes everyday life but also revolutionizes human society. Service requirements are driving the development of 5G technologies. 5G industry innovation represents uplink ultra-large bandwidth, ultra-low latency, end-to-end slicing, and mobile edge computing (MEC). Based on the digital requirements of the industry, Huawei and China Telecom proposed the 5G Super Uplink Joint Technology Innovation solution. It is another breakthrough after Huawei CloudAIR solution."
Yang Chaobin, president of 5G Product Line, Huawei Technologies Co., Ltd., noted: "The Super Uplink solution can meet the service requirements of large bandwidth and low latency at the same time. We are honored to work with China Telecom to implement the test and verification of 5G Super Uplink. Huawei 5G supports end-to-end Super Uplink and co-deployment of NSA and SA. Huawei will help industry partners continuously innovate to create the optimal 5G experience."
China Telecom and Huawei continue to cooperate closely in technological innovation, promote 5G innovation, and contribute to 5G industry development. Huawei will support the strategic goal of China Telecom's 5G development as always, and deepen cooperation on Super Uplink to help China Telecom take the lead in the new era of a 5G intelligent world.
