3GPP 5G Channel Model Standard: Opens a New Era of Mobile Industry in High Frequency Bands

The first standard for the mobile broadband 5G high-frequency (6-100 GHz) channel model was sought to be approved at the recent 3rd Generation Partnership Project (3GPP) RAN Meeting held in Bushan Korea.

Huawei is known to have partaken in 70+% technical topics and contributed innovative solutions sharing fundamental contributions to the 3GPP standard on 5G high-frequency channel model.

The Chinese networking giant had launched extensive high-frequency channel measurement campaigns over the past years which cover typical frequency bands including 8 GHz, 15 GHz, 28 GHz, 60 GHz, and 73 GHz, and large amount of channel measurement data that are collected and analyzed over the typical deployment scenarios including  indoor offices, shopping malls, and downtown areas etc.

Huawei has reported to make innovations in channel modeling techniques in aspects of multiple key technologies including multi-zone path loss model, antenna decoupling, LOS probability model, spatial consistency model, frequency-dependent channel model, outdoor-to-indoor model, channel parameterization of indoor and outdoor models, and link models.

All these techniques are said to have been approved and accepted by the 3GPP.

Early in 2013, Huawei reports to have announced the release of its high-frequency prototype based on E-band (73GHz), which reached a peak data rate of 115 Gbps. During the Mobile World Congress in February 2016, Huawei and Deutsche Telekom jointly launched a high-frequency prototype and testbed that realized multi-user beam-tracking function with a peak data rate of 70 Gbps in the mixed line-of-sight and non-line-of sight environment. The prototype further verified the feasibility of applying high frequency bands to mobile communications.

The Company also collaborated with industrial partners to promote high-frequency research. In conferences of the Institute of Electrical and Electronics Engineers (IEEE), Huawei has organized multiple seminars to share the research results of high-frequency channel model, air interface design, and field trials etc. Moreover, Huawei is known to have established technical cooperation on high-frequency communications with over 10 universities and institutions globally, and has published 51 academic papers in the IEEE journals and conferences.

In 2016, Huawei co-authored with 15 industrial partners and academic institutions and released white papers entitled “5G Channel Model for Bands Up To 100 GHz”, which have become important baseline references for 5G high-frequency channel modeling.

The agreement of 3GPP 5G high-frequency channel model standard is an important milestone of the application of above-6GHz bands to 5G, which opens a new landscape for the standardization of 5G high-frequency technologies.  5G will provide a fiber-speed user experience in the applications of future ultra-broadband wireless access, ultra-high traffic hotspots, and virtual realization. With sufficient spectrum resources in above-6GHz frequency bands, 5G can laid a solid foundation for providing superior mobile connectivity and realize the Internet of Things (IoT) as well.
