Paving the way for wider 5G commercial deployment in China Ericsson and China Telecom (Sichuan) have successfully completed China’s first 5G Standalone (SA 5G) Ericsson Spectrum Sharing data call on a commercial network.
The milestone was achieved recently on China Telecom’s 2.1-GHz commercial 5G network in Deyang City, Sichuan Province. The successful demo shows that Ericsson Spectrum Sharing can be deployed on a dual mode 5G Core-enabling 5G Standalone network. It provides another option for communications service providers such as China Telecom to speed up the roll-out of 5G services.
Ericsson Spectrum Sharing is a new way of rolling out 5G that uses existing hardware, spectrum and sites, while enabling increases in mid/high band coverage. It enables 4G, 5G NSA NR and 5G Standalone to be deployed simultaneously across FDD spectrum without the need for dedicated 5G spectrum. With Ericsson Spectrum Sharing, 5G radio resources are shared on a 1 millisecond basis, maximizing spectral efficiency. Most 5G networks have so far been deployed in Non-Standalone (NSA) mode where the underlying 4G network layer supported the necessary signaling. SA removes this 4G dependency. With Ericsson Spectrum Sharing coupled with 5G SA technology, China Telecom can roll out FDD New Radio 5G SA networks as part of its wider 5G commercial deployment in the country.
Enabling nationwide 5G SA coverage in FDD bands using Ericsson Spectrum Sharing will also help lay the foundation for introducing 5G services such as Voice over NR, as well as significantly extending coverage of higher frequency 5G NR TDD bands using carrier aggregation.
