HSINCHU, Taiwan – MediaTek today announced it has reached a 5G carrier aggregation (CA) and Voice over New Radio (VoNR) milestone in collaboration with Swisscom, Ericsson and OPPO, advancing 5G networks across Europe.
Through this joint initiative, 5G CA between frequency division duplex (FDD) low band and time division duplex (TDD) mid band was achieved in both Non-Standalone (NSA) and Standalone (SA) network architectures. FDD was deployed simultaneously with LTE using the same spectrum resources and utilizing the Dynamic Spectrum Sharing (DSS) technique. Aggregating the FDD band with its wider coverage capabilities together with the TDD band will help to extend the coverage of the higher peak rate capabilities of the TDD band and increases network capacity. FDD-LTE and FDD-TDD are both important in paving the way for 5G SA deployment, ensuring a seamless 5G user experience and extended capacity.
