mmWave Channelization Scheme for Sub-10 GHz Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mmWave wireless communication systems face challenges in efficiently communicating mmWave Physical Layer (PHY) Protocol Data Units (PPDUs) due to differences in channelization schemes between sub-10 GHz and mmWave bands, leading to compatibility issues and reduced coexistence between devices operating on different channelization schemes.
Innovation Solution
The implementation of a mmWave channelization scheme that is compatible with sub-10 GHz schemes, allowing for the reuse of PHY and MAC components, and the use of upclocking mechanisms to generate PPDU transmissions, along with energy detection mechanisms for coexistence, enables efficient communication over mmWave channels.

Engineering Contradiction Analysis
1Productivity
If a mmWave-specific channelization scheme is used, then mmWave communication performance is improved, but compatibility with sub-10 GHz devices and coexistence between different band devices deteriorates
Solution Approach 1:
The patent implements a universal channelization scheme where mmWave channels are designed to be compatible with sub-10 GHz channelization principles. This allows the same PHY and MAC components to operate across both frequency bands, enabling multi-functionality without requiring separate dedicated hardware paths for each band
Solution Approach 2:
The patent applies parameter changes by adjusting channel bandwidth and center frequency parameters to align mmWave channelization with sub-10 GHz schemes. By modifying these physical layer parameters, the system achieves compatibility while maintaining optimized performance characteristics for mmWave operation
2Reliability
If separate PHY and MAC components are designed for mmWave and sub-10 GHz bands, then band-specific optimization is improved, but device complexity and development costs increase
Solution Approach 1:
The patent designs PHY and MAC components with universal functionality that supports both mmWave and sub-10 GHz bands through a single codebase. This reduces device complexity by eliminating the need for separate dedicated components while maintaining band-specific optimization through configurable parameters and adaptive operation modes
Solution Approach 2:
The patent implements dynamic operation where the PHY and MAC components can adapt their behavior based on the operating band. The system dynamically adjusts channelization parameters, bandwidth configurations, and operational modes to optimize performance for the currently active band while maintaining compatibility across both mmWave and sub-10 GHz frequencies

AI summary
For example, a wireless communication device may be configured to determine an energy state of a 2.16 Gigahertz (GHz) channel bandwidth (BW) in a millimeterWave (mmWave) wireless communication frequency band according to an energy detection mechanism; and, based on the energy state of the 2.16 GHz channel BW, to select between allowing or disabling the wireless communication device to transmit an mmWave Physical layer (PHY) Protocol Data Unit (PPDU) over an mmWave wireless communication channel, which at least partially overlaps the 2.16 GHz channel BW and is different from the 2.16 GHz channel BW, the mmWave wireless communication channel having an mmWave channel BW of at least 80 Megahertz (MHz).
