Huawei and China Telecom Launch Innovative 5.5G Super TimeFreq Folding

China Telecom and Huawei have been jointly innovating technologies to address major challenges in different stages of 5G development. They have launched the Super Uplink and Super Frequency Fusion technologies, which boost 5G uplink capabilities and raise the utilization of discrete spectrums, respectively. As the newest in such 'Super' series, Super TimeFreq Folding simulates the FDD air interface through uplink and downlink time-domain complementation of dual TDD carriers, leveraging both the TDD large bandwidth and low latency over the FDD air interface. On the 3.5 GHz band, Super TimeFreq Folding can provide an uplink equivalent bandwidth of up to 100 MHz and reach an uplink peak rate of more than 1 Gbps while shortening the E2E latency from 10 ms to less than 4 ms. The use of mmWave in the future will further slash the latency to less than 1 ms. Featuring large uplink bandwidth, low latency, high reliability, and ultra-large network capacity, Super TimeFreq Folding can better meet 5G performance requirements of core production processes; help industry customers improve quality, reduce costs, and increase efficiency; and accelerate industry digital transformation.

With collaboration among China Telecom, Huawei, and all other industry partners, 5G will become a new momentum driving China's high-quality economic development and usher the beginning of a smart world.
