Multi-link Association Response Frame for Flexible Link Establishment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multi-link establishment methods in communication technologies, such as IEEE 802.11ax, lack flexibility in establishing and managing multiple links, as they primarily rely on a status code field to indicate association success, without providing specific status information for each link.
Innovation Solution
The proposed method involves using a multi-link association response frame that carries radio bitmap information, allowing the STA MLD to determine which radio is allowed for each link, thereby indicating successful or failed link establishment. This enables fast link switching and improves multi-link establishment flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If only a status code field is used to indicate association success, then the indication is simple, but the specific establishment status of each link cannot be learned
Solution Approach 1:
The patent segments the link establishment status indication by introducing separate status code fields for each link (first link status code field and second link status code field) in the association response frame. This allows each link's establishment status to be independently indicated, resolving the information loss while maintaining clear structure.
2Adaptability or versatility
If multi-link establishment flexibility is improved by providing detailed status information, then link management becomes more precise, but the frame structure becomes more complex
Solution Approach 1:
The patent applies local quality by making the frame structure adaptable - the presence or absence of status code fields for different links is determined by local conditions (whether each link is successfully established). This allows the frame to contain only the necessary information for each specific scenario, balancing flexibility with complexity management.
Solution Approach 2:
The association response frame is designed dynamically, where the inclusion of first and second link status code fields depends on the actual link establishment outcomes. This dynamic structure allows the frame to adapt its complexity based on the specific multi-link establishment scenario, providing flexibility without unnecessary complexity.

AI summary
This application discloses a multi-link establishment method and a related device. A multi-link association response frame carries radio bitmap information, to indicate an AP allowed to be associated with a radio of a STA MLD or a link allowed to be established by using a radio of a STA MLD, so that the radio subsequently switches between different APs or links. The multi-link association response frame carries link establishment status information, to indicate a link establishment status of each link that the STA MLD requests to establish, so that multi-link establishment is more flexible. The multi-link association response frame carries reassociation information, to indicate whether each parameter in association configuration information is reserved, so that a problem that signaling overheads are relatively large due to a reassociation operation is avoided. It can be learned that, in the multi-link establishment method, the foregoing information is carried to improve multi-link establishment flexibility.
