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.
“As a 5G innovation pioneer, MediaTek has a long history of working with Swisscom, Ericsson and OPPO on 5G to usher in this new era of ultra-fast connectivity,” said JS Pan, General Manager of Wireless Communication System and Partnership at MediaTek. “This is just the beginning of the 5G SA journey in Europe and MediaTek is committed to bringing it live to its full extent. Our Dimensity series of powerful and energy-efficient 5G SoCs are designed to support NR CA across multiple configurations, as well as native VoNR support, to ensure a seamless user experience.”
VoNR represents a major step towards the migration to 5G SA systems. This will allow OEMs to bring new services to market. With SA networks, 5G applications will be able to go beyond enhanced Mobile Broadband (eMBB) targets of high data throughput to meet the ultra-low latency and reliability requirements of mission-critical use cases and enable next generation of massive IoT deployment.
Both accomplishments were made on Swisscom’s commercial 5G network using Ericsson’s network infrastructures including its RAN, Core Network and IMS solutions. In addition, the milestones were reached on commercially available OPPO Reno 4Z 5G devices powered by MediaTek’s Dimensity 800 SoC and MediaTek Dimensity 1000+ SoC test user equipment (UE).
“Bringing 5G standalone to the market requires a strong collaboration with our customers and partners. This latest achievement using industry-leading solutions like 5G carrier aggregation is an important step towards realising the full benefits of 5G,” said Hannes Ekström, Head of Product Line 5G RAN, Ericsson.
