Huawei said the new test is based on the latest version of 3GPP Release 15 specifications

Intel and Huawei said they have completed 2.6 GHz 5G New Radio interoperability and development testing (IoDT) based on the latest 3GPP Release 15 specifications from September 2018.

Huawei claimed that this testing is the world’s first 2.6 GHz 5G interoperability test under a standalone network and is a key step towards accelerating the maturity of the 2.6 GHz 5G NR ecosystem.

The trial used Intel’s 5G Mobile Trial Platform (MTP) and Huawei’s latest 5G NR base station supporting 2.6 GHz with 160MHz bandwidth.

“The successful completion of this IoDT test not only marks the end-to-end successful interoperability of 5G in the 2.6 GHz band, but also lays a foundation for large-scale commercial launch. It will promote the development and maturity of the 5G end-to-end industry in the 2.6 GHz band,” the Chinese vendor said in a statement. “In the future, Intel and Huawei will continue to carry out more test and commercial verification, and promote the rapid maturity of the ecosystem, laying a solid foundation for the future 5G commercialization.”

In related news, Huawei also claimed to be the first company to complete a 5G SA functional and performance test of 5G LampSite. The test took place in the third phase of China 5G technology research and development tests organized by the IMT-2020 (5G) Promotion Group.

Huawei said that the results demonstrated a peak downlink rate of above 1.8 Gbit/s on the C band with a bandwidth of 100 MHz, which is close to the theoretical peak rate. The vendor said that this is the first time that indoor coverage tests have been performed for 5G SA based on the most comprehensive 3GPP Release 15 specifications.

The IMT-2020 (5G) Promotion Group introduced indoor coverage as a part of its third phase of R&D tests. In its new releases of technical specifications for 5G digital indoor system and test cases of 5G digital indoor system, this group defined a series of technological specifications for 5G indoor coverage digitalization in terms of performance, functions and networking.

Testing was conducted in laboratories at China Academy of Telecommunication Research and in field environments in Beijing. Tests performed included verification of key indoor aspects of 5G Radio Access Networks, including uplink and downlink peak rates, downlink four-transmit four-receive, and uplink and downlink 256 QAM as well as multi-user performance.

“With a 100 MHz wide C-band spectrum, a downlink single-user peak rate of more than 1.8 Gbit/s was achieved on Huawei 5G LampSite, which will be set to take indoor experience to a new height,” Huawei said.

China’s 5G R&D tests, which are being carried out by the IMT-2020 (5G) promotion group, started in 2016 and are expected to be concluded by the end of this year. These tests involve three phases: key technologies testing, the verification of technology and solution and 5G system verification.

Operators participating in the IMT-2020 Promotion Group include China Mobile, China Telecom, China Unicom and Japanese telecoms operator NTT DoCoMo. Vendors which are part of the initiative are Huawei, ZTE, Ericsson, Nokia, Datang and Samsung. A number of chipset and test measurement vendors, including Qualcomm, Intel, Mediatek, Ctec, Keysight Technologies and Rohde & Schwartz are also part of the initiative.
