Interoperability test with three combinations of NR FDD/TDD carrier aggregation
General News

The test, conducted in Ericsson’s lab in Beijing, reached close to 2.66Gbps speeds with 7:3 TDD patterns on 200MHz total aggregated bandwidth. The test included different channel bandwidth configurations, showcasing the flexibility and scalability of the Dimensity 1000+ to support different spectrum holdings for carriers worldwide. This type of CA technology will allow communication service providers to deploy 5G more widely, offering downlink speeds of over 400Mbps in nationwide coverage by aggregating FDD spectrum assets. “Our Dimensity portfolio of high performance and ultra-low power chipsets support several different carrier aggregation configurations for comprehensive NR CA support.” Per Narvinger, Head of Product Area Networks at Ericsson, said: “Carrier aggregation technology is a must in order to deploy a better 5G: boosting coverage, capacity and speed by enabling the combination of available 5G spectrum assets. Our tests with MediaTek are continuing to build the foundation for 5G networks that will provide consumers with better 5G experiences and help service providers to deliver 5G more efficiently.” The tests were conducted in lab settings with a MediaTek Dimensity 1000+ commercial chipset and an Ericsson AIR 6488 5G radio using 5G NR commercial software and Ericsson’s dual-mode 5G Cloud Core solution.
