The big picture
The 5G mmWave Channel Model Alliance launched in July 2015 to provide a nexus for global efforts to define the future radio channels through which next-generation 5G wireless will operate. NIST’s Communications Technology Laboratory coordinates this international alliance of companies, universities and government institutions to support the development of more accurate, consistent, and predictive channel models. Critically, the alliance’s shared database makes available to all members data related to methodology, best practices, and actual channel-model test results.
There is no membership fee, and working group meetings are conducted via conference calls and Web Experience Notes. Outcomes from working group meetings are posted on the 5G mmWave Channel Model Alliance Wiki, a collaborative platform for group participants to exchange information, ask questions and learn about working group meeting activities.
What we do
The 5G mmWave Channel Model Alliance will provide a venue to promote fundamental research into measurement, analysis, identification of physical parameters, and statistical representations of millimeter-wave propagation channels.
More specifically we are:
• Developing usage scenarios for indoor, outdoor and emerging environments.
• Refining, improving, and troubleshooting initial channel models developed by international standards-making bodies.
• Focusing on unaddressed usage scenarios, parameters, frequencies, and architecture.
• Providing a source of continuity for stakeholders involved in different stages in the standards development lifecycle.
• Serving as a liaison to other consortia and international groups.
• Aggregating new and improved channel measurement and modeling methodologies and best practices.
• Feeding results to standards organizations such as 3GPP and IEEE 802 for the development of future mmWave wireless communication systems.
We approach these efforts via six working groups:
1. Steering Committee
2. Measurement Methodology
3. Modeling Methodology
4. Indoor Usage Scenarios
5. Outdoor Usage Scenarios
6. Emerging Scenarios
Why we do it
To address fragmented and narrowly scoped mmWave channel modeling activities, pulling together resources under one alliance makes it possible to provide an in-depth understanding of the unique mechanisms related to millimeter-wave propagation and be better equipped to address as specific needs arise for each wireless systems application. An immediate goal of the group is to develop improved models by use of the vast but dispersed data being collected by multiple groups (NIST, METIS2020, COST1004, IEEE 802.11ay, ETSI mmWave SIG, NYU Wireless) using various channel sounding techniques.
Alliance participants collect and contribute data from standardized scenarios by multiple channel sounders, each with its own unique capabilities. Collaboration through the Alliance provides a more comprehensive view of a given propagation environment than could be achieved with a single channel sounder alone. In addition, Alliance participants often use channel sounders with different antenna types, which can provide a more complete picture of the required spatial characteristics for the models.
The 5G mmWave Channel Model Alliance intends to systematically characterize indoor, outdoor, and emerging scenarios through common processing routines and analysis techniques that are standardized across its working groups. This characterization of diverse environments will incorporate multiple points of view and provide a strong physical basis to develop more accurate and predictive channel models.
