China’s IMT-2020 (5G) promotion group announced that it has completed the third phase of non-standalone (NSA) trials and reached the halfway point in standalone (SA) trials based on 3GPP’s Release 15 standards unveiled in June and December 2017.

Tests covered indoor and outdoor trials, core network and base station functions. Huawei, ZTE and China Information and Communication Technologies Group completed trials using the 3.5GHz and 4.9GHz frequency bands.

This phase saw the participation of more than 20 companies, such as Ericsson, Nokia Shanghai Bell, Samsung, Qualcomm, Intel and Rohde & Schwarz.

Yang Chaobin, president of Huawei 5G product line, said, “The test results showed Huawei’s confidence in providing operators with mature and reliable 5G end-to-end commercial products. They were also the result of the joint efforts of Huawei and many industry partners.”

After completing this step, the group intends to conduct interoperability tests on system and chip system terminals.
