Multi-Link Reconfiguration Frames for Active Link Negotiation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional Multi-Link Configuration Action frames lack fields to indicate changes in the number of active links and define operating capabilities of Multi-Link Devices (MLDs), leading to inefficiencies in wireless operations.
Innovation Solution
The implementation of a Reconfiguration ML Information Element (IE) within the ML Configuration Action frame to manage changes in the number of active links, including fields that define operating capabilities and negotiate link configurations, such as Common Info, Per Link Info, and NSTR Bitmaps, to ensure efficient wireless operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional ML Configuration Action frames are used, then frame structure is simple, but the frames lack fields to indicate changes in the number of active links and define operating capabilities
Solution Approach 1:
The patent segments the frame information by introducing a Reconfiguration ML Information Element (IE) that is separated from the basic frame structure. This IE contains specific fields for link changes and capabilities, allowing the frame to carry additional information without fundamentally redesigning the entire frame structure.
Solution Approach 2:
The patent adds a new dimension to the frame structure by incorporating the Reconfiguration ML IE, which provides an additional layer of information about link configuration changes. This allows the frame to convey both basic control information and detailed reconfiguration data simultaneously.
2Reliability
If the number of active links is changed without reconfiguration fields, then operations are faster, but link management becomes inaccurate and unreliable
Solution Approach 1:
The patent applies preliminary action by pre-defining the Reconfiguration ML IE structure with all necessary fields for link changes and capabilities before actual link reconfiguration occurs. This allows devices to negotiate link changes efficiently using the pre-established information framework, reducing negotiation time while ensuring reliability.
Solution Approach 2:
The patent implements feedback mechanisms through the Reconfiguration ML IE, which provides structured information about link changes and capabilities. This enables receiving devices to accurately process and respond to reconfiguration requests, ensuring reliable link management while maintaining efficient communication through standardized feedback fields.
