Modeling Wireless Channels for Future 6G Networks
This patent describes a method for creating detailed mathematical models of how wireless signals travel in future 6G networks, covering all types of frequencies and environments.
Original patent title: “6G pervasive channel modeling method suitable for all frequency bands and all scenarios”
This patent describes a method for creating detailed mathematical models of how wireless signals travel in future 6G networks, covering all types of frequencies and environments. Granted to Southeast University in 2025 with 10 claims, and it is expected to expire in 2043.
Coverage
What does this patent actually cover?
This patent details a method for creating comprehensive models of wireless communication channels, specifically for 6G networks. It starts by defining the environment, like the frequency band (from sub-6 GHz to terahertz), the type of antennas used, and the placement of devices. Then, it calculates various signal losses, including path loss, shadowing (obstacles), and weather effects. The method models how signals bounce off surfaces (scatterers) to determine their delay, angle, and strength. Finally, it accounts for movement of devices and changes in the environment over time to update these channel models dynamically, ensuring accurate signal transmission and reception.
The gap
What does this patent NOT cover?
- Modeling methods that do not account for both large-scale and small-scale fading effects simultaneously.
- Channel models that are limited to only specific frequency bands like only sub-6 GHz or only millimeter wave.
- Methods that do not consider the spatial consistency of channel parameters.
- Models that do not include the 'birth-death' process of signal clusters over time.
- Channel modeling for existing 4G or 5G networks that do not incorporate the specific elements defined for 6G.
These exclusions are unique to PatentBrief — derived from the actual claim language, not patent-office boilerplate.
Key facts
