Qualcomm Technologies and Ericsson said they have completed interoperability tests for 5G standalone (SA) carrier aggregation across both FDD/TDD and TDD/TDD bands.
The partners explained that 5G carrier aggregation technology allows operators to use multiple sub-6 GHz spectrum channels simultaneously to transfer data between base stations and a 5G mobile device. This key 5G capability is expected to be widely deployed by operators around the world in 2021.
The two companies completed a 5G SA carrier aggregation test at Ericsson’s labs in Beijing, China. The connection reached 2.5 Gbps peak speeds by aggregating 100 megahertz + 60 megahertz within the 2.5 GHz (n41) TDD band in a 70% downlink configuration and using 4×4 MIMO.
