Huawei and MediaTek have completed a 5G NR interoperability and development testing for a solution based on the 3GPP's Super Uplink standard in a lab environment.
The testing has verified in full scale the solution performance regarding user access, dynamic carrier switching, uplink and downlink throughput, mobility, and feature interoperability, said Huwei.
This testing is performed on terminals equipped with the MediaTek 5G M70 baseband chipset and Huawei's latest 5G base station. The time division multiplexing technology of the uplink channel of terminal antennas has been verified, which is a major breakthrough for both MediaTek and Huawei. Also, this testing verified the feasibility of dynamic switching of the terminal's uplink channel across frequency bands. This means that with the Super Uplink solution, the terminal can flexibly utilize uplink resources of different frequency bands, converging and thereby improving uplink capabilities.
Additionally, based on the latest 3GPP standard, this testing has proved that terminals' switching latency requirement of uplink transmission can be further lowered. This lifts constraints on terminal technologies, so that Super Uplink will be supported on a much wider range of terminals. This will create a favorable condition for operators to provide an improved experience for both common and enterprise users, said Huawei.
