MediaTek, Ericsson 5G interoperability test

This test is in preparation for the rollout of 5G standalone networks. It is the first successful test that completed all three combinations of new radio (NR) time division duplex and frequency division duplex carrier aggregation on a single Dimensity 5G chipset.

Three combinations included carrier aggregation of TDD+TDD, FDD+TDD, and FDD+FDD. They were able to establish the 5G SA data call on 200MHz total aggregated bandwidth. The test also included different channel bandwidth configurations, showcasing the flexibility and scalability of the Dimensity 1000+ to support different spectrum holdings for carriers worldwide.

There were also tests for FDD bands, sub-2.6GHz, CA tests on two carrier components of 20MHz or both non-standalone and SA networks. This type of CA technology will allow communication service providers to deploy 5G in a wider coverage offering down speeds of over 400Mbps in nationwide coverage by aggregating FDD spectrum assets.

The combination of NR FDD sub-2.6GHz and NR TDD sub-6GHz aims to provide better both coverage and capacity enhancements. The tests showed how seamless groupings of 5G connections can provide over 30 percent greater throughput on average. This allows service providers to manage 5G capacity more efficiently.

The tests were conducted in lab settings using 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. The implementation is fully compliant with 3GPP’s Release 15 specifications for 5G.
