Beacon Frame Non-Inheritance Element Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Wi-Fi specifications cannot efficiently transmit beacon frames with vendor-specific elements having variable-length identifiers, as they rely on element identity and extension, which limits the ability to identify non-inherited elements.
Innovation Solution
A wireless communication method that establishes multiple links and transmits frames with non-inheritance elements, using specific formats to list element IDs and identifiers that are not inherited from one link to another, allowing for efficient identification of unique elements across links.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If element identity and element ID extension are used to identify elements, then the beacon frame can be reduced in size through inheritance, but vendor-specific elements with variable-length identifiers cannot be properly identified
Solution Approach 1:
The element identification is segmented into multiple parts: element ID (2 bytes), element ID extension (2 bytes), and additional identifier fields (variable length). This segmentation allows the system to maintain the compact inheritance mechanism while adding capacity for vendor-specific identifiers without increasing the base structure size.
Solution Approach 2:
The patent adds a new dimension to element identification by introducing variable-length identifier fields beyond the fixed element ID and extension. This allows identification to extend into an additional dimensional space, enabling vendor-specific elements to be uniquely identified while preserving the original identification mechanism for standard elements.
2Loss of information
If all element information is transmitted for each link, then complete information is provided, but the beacon frame size increases significantly
Solution Approach 1:
The patent extracts only the non-inherited elements into a dedicated non-inheritance element list. By separating inherited elements (which are implied from the reporting STA) from non-inherited elements (which are explicitly listed), the beacon frame transmits only the necessary additional information, significantly reducing frame size while maintaining information completeness.
Solution Approach 2:
The patent establishes inheritance relationships in advance, where the reporting STA's element profile serves as a preliminary definition for reported STAs. This preliminary action allows receiving devices to pre-load the inherited element information, so that only deviations (non-inherited elements) need to be transmitted in the beacon frame.
3Device complexity
If a unified element identification system is used, then simplicity is maintained, but vendor-specific elements with extra identifiers cannot be supported
Solution Approach 1:
The patent creates a universal identification system that serves multiple functions: it identifies standard Wi-Fi elements using element ID and extension, and simultaneously identifies vendor-specific elements by incorporating variable-length additional identifiers. This multi-functional identification system maintains simplicity for standard elements while providing extended capability for vendor-specific elements.
Solution Approach 2:
The patent applies different identification qualities to different element types. Standard elements use the simple element ID and extension format, while vendor-specific elements utilize the extended format with additional variable-length identifiers. This local differentiation allows each element type to use the appropriate level of identification complexity.
