Huawei and China Telecom jointly held the 5g advanced innovative technology conference of "super time-frequency folding" and demonstrated the laboratory test and verification results of relevant technologies. It is understood that the super time-frequency folding simulates the FDD air interface through TDD dual carrier uplink and downlink time-domain complementarity, and integrates the advantages of TDD large bandwidth with the "0-wait" delay advantages of FDD air interface. Based on the 3.5G Hz band, the super time-frequency folded uplink equivalent bandwidth is up to 100m Hz, which can realize the uplink peak rate of more than 1Gbps, and shorten the end-to-end delay from 10ms to less than 4ms. In the future, based on the millimeter wave band, the delay can be further reduced to less than 1ms.
