Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a single WLAN apparatus operates multiple virtual APs for multiple BSSs, then the quantity of STAs supported increases, but the device complexity and management overhead increase
Solution Approach 1:
The patent implements multi-link aggregation where a single WLAN apparatus can operate multiple virtual APs (BSS1, BSS2, etc.) simultaneously across different frequency bands. The apparatus provides universal functionality by handling multiple BSS operations, STA associations, and link management through a unified control mechanism, allowing one device to perform what traditionally required multiple separate APs
Solution Approach 2:
The patent employs a nested structure where multiple BSSs are contained within a single WLAN apparatus. Each BSS is further nested with multiple communication links (first communication link, second communication link) that can be independently managed. The link profile structure itself is nested, containing management elements that can be conditionally inherited or customized for each link level
2Productivity
If multiple communication links are established for multi-link aggregation, then network performance and bandwidth increase, but the complexity of managing different link profiles and management elements increases
Solution Approach 1:
The patent establishes link profiles in advance before actual communication occurs. Each link profile pre-configures the necessary management elements and parameters for potential communication links. When a link is needed, the pre-configured profile can be quickly activated or customized, avoiding the need to create and negotiate link parameters in real-time, thus reducing management complexity while maintaining performance
Solution Approach 2:
The patent allows different link profiles to have customized management elements specific to each communication link's requirements. The first link profile may contain elements optimized for the first frequency band, while the second link profile contains elements suited for the second frequency band. This local customization enables each link to operate at optimal performance while the overall system manages diversity through structured inheritance mechanisms
3Reliability
If management information is customized for each communication link, then link-specific optimization improves, but the loss of time for processing and transmitting customized management frames increases
Solution Approach 1:
The patent enables conditional inheritance where management elements in link profiles can be dynamically customized or inherited based on parameters such as frequency band, link type, and STA capabilities. By changing parameters like inheritance flags and customization levels, the system can switch between fully customized management frames and inherited templates, optimizing the balance between link-specific reliability and processing time based on current network conditions

AI summary
This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for implementing multi-link aggregation and conditional inheritance in a first basic service set (BSS). In one aspect, an apparatus may establish a first communication link with a first station (STA) of the first BSS using a first frequency band. The apparatus may determine a first link profile for a second communication link by customizing one or more management elements of management information associated with the first communication link. The apparatus may configure a first non-inheritance element of the first link profile associated with the second communication link to indicate usage of at least one management element of the management information by the second communication link is disabled. The apparatus may generate a management frame that comprises at least the first link profile, and may output the management frame for transmission.
