WLAN Multi-Link Association Setup With Link-Specific Capability Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The overhead in wireless local area network (WLAN) systems is excessive due to the transmission of complete information on all stations and access points during multi-link device setup, which can be inefficient.
Innovation Solution
Only transmit information on requested and accepted links during the multi-link device setup, reducing overhead by focusing on necessary link-specific data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If complete information on all STA and APs included in MLD is transmitted during multi-link setup, then comprehensive device information is provided, but overhead becomes excessively great
Solution Approach 1:
The patent segments the information transmission by link, where each link's setup process transmits only the capability information relevant to that specific link rather than all possible links. This segmentation reduces the overall overhead while maintaining the completeness of information needed for each individual link setup.
Solution Approach 2:
The patent applies local quality by transmitting different amounts of information based on the specific link being configured. Each link receives only the capability information necessary for its operation, rather than all STAs and APs information. This localized information transmission reduces overhead while ensuring each link has the complete information it needs.
2Reliability
If complete information on all STA and APs is transmitted during setup, then all devices can be properly configured, but the setup process becomes less efficient
Solution Approach 1:
The setup process is segmented into individual link setup procedures, where each link is configured separately with only its relevant capability information. This segmentation maintains configuration accuracy for each link while significantly improving overall setup efficiency by avoiding the transmission of unnecessary information for other links.
Solution Approach 2:
The patent applies partial action by transmitting only the necessary capability information for each specific link being configured, rather than transmitting all possible information. This partial transmission is sufficient for reliable link setup while greatly improving setup efficiency by reducing overhead.

AI summary
In a wireless local area network (WLAN) system, an STA MLD may include a first STA and a second STA, wherein the first STA operates on a first link, and the second STA operates on a second link. The STA MLD may transmit an association request frame to an access point (AP) MLD. The association request frame may include capability information of a requesting STA, which requests to be associated with the AP MLD, among STAs included in the STA MLD and information related to a request link, to with which a request to be associated is transmitted by the requesting STAs. The STA MLD may receive an association response frame from the AP MLD. The association response frame may include capability information of an AP that operates in a link, an association with which is accepted by the AP MLD, among the request links.
