PHY Header Parameter Encoding for Wireless Channel Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication networks, especially those operating at 60 GHz frequencies, there is a challenge in efficiently notifying devices about channel usage configurations, including primary channels and data transmission channels, to ensure successful communication without incurring significant overhead.
Innovation Solution
The implementation of parameter encoding techniques that use index values or bitmaps within Physical Layer (PHY) headers to specify channel usage configurations, allowing wireless communication devices to notify other devices of the applicable channel usage parameters with minimal overhead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If detailed channel usage configuration information is transmitted to notify devices of bandwidth and spectrum portions being used, then communication reliability is improved, but communication overhead increases
Solution Approach 1:
The channel usage configuration information is segmented into two separate fields in the PHY header: a first field for data transmission channel information and a second field for primary channel information. This segmentation allows efficient encoding and transmission of configuration parameters, reducing overall overhead while maintaining complete notification capability for successful communication.
Solution Approach 2:
The patent employs parameter encoding techniques where channel usage configuration is represented through encoded parameters (such as index values or compact bit representations) rather than transmitting full descriptive information. This parameterization significantly reduces the quantity of data that must be transmitted while preserving all necessary configuration details for reliable communication.
2Productivity
If channel usage configuration parameters are encoded in PHY headers, then notification efficiency is improved, but header complexity increases
Solution Approach 1:
The PHY header is segmented into distinct fields with specific functions: a first field containing data transmission channel information and a second field containing primary channel information. This segmentation organizes complexity into manageable, well-defined sections that can be processed efficiently by communication devices.
Solution Approach 2:
Instead of embedding complex nested structures within the PHY header, the patent inverts the approach by using separate, parallel fields that can be independently decoded. This inversion simplifies the header structure while maintaining the ability to convey comprehensive channel configuration information efficiently.
