Ericsson has announced 5G New Radio (5G NR) interoperability trials alongside global carriers following the 3GPP standardisation of non-standalone (NSA) 5G NR specs this week.

The trials included Australian mobile carrier Telstra; United States carriers T-Mobile, Verizon, Sprint, and AT&T; Japanese carrier NTT DoCoMo; Korean carrier SK Telecom; and European carriers Vodafone and Orange, as well as smartphone chip giant Qualcomm.

The live demonstrations, which took place in Ericsson’s lab in Kista, Sweden, and Qualcomm’s research lab in New Jersey, US, saw the companies utilise the 3.6GHz and millimetre-wave (mmWave) 28GHz spectrum frequencies using Ericsson’s pre-commercial 5G base stations and Qualcomm’s 5G NR UE prototypes.

Ericsson said the demonstrations were part of ongoing industry collaboration accelerating 5G NR ahead of commercial network launches in 2019.

“This milestone builds on years of researching and developing 5G technology as well as on leading and contributing to the standardisation work. By working closely with our key partners in early trials and fine tuning our global portfolio, we ensure that we can bring the standard-compliant technology to the benefits of our customers and their customers,” Ericsson EVP and head of Business Area Networks Fredrik Jejdling said.

Ericsson said the demonstration complied with 3GPPs 5G NR specifications including Massive Multiple-Input Multiple-Output (Massive MIMO); mmWave support for adaptive beamforming and beam-tracking technologies; Orthogonal Frequency Division Multiplexing (OFDM)…
