Huawei and Intel announced they have completed a standalone 5G call test based on 3GPP Release 15 standards for the third phase of China's 5G technology R&D trials.
The trials organized by China's IMT-2020 promotion group was conducted at the group's laboratory using a Huawei 5G base station and core network and Intel's third generation 5G Mobile Trial Platform.
Utilizing the 3.5-GHz frequency band, Huawei and Intel tested full stack initial access, registration and radio bearer establishment with the 5G new radio resource control (NR RCC) and non-access stratum (NR NAS) protocol stack.
Intel and Huawei completed nonstandalone 5G interoperability and development testing in June in collaboration with China Mobile, and the two vendors commenced field trials for China's third-phase 5G R&D test in August.
“The completion of the SA test, based on the R15 protocol, is another important milestone for Huawei in China's Third-Phase 5G R&D test,” Huawei president of 5G products Yang Chaobin said.
“Huawei will continue focus on system commercialization in the Third-Phase 5G R&D test, and together with industry partners will promote 5G business success."
Intel and Ericsson meanwhile completed the first end-to-end nonstandalone 5G data call in July during a trial at Ericsson's lab in Sweden.
