Multi-Link Communication Reachability for Adaptive Link Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The actual communication state of links in multi-link setups often differs from the enabled state due to varying communication reachability between links, particularly when extended frequency bands like millimeter waves are used, leading to inconformity in link management.
Innovation Solution
A method where a non-AP MLD initiates multi-link setup based on communication reachability between non-AP STAs and APs, managing links according to their reachability to ensure conformity between the actual and enabled states by adjusting link statuses to disabled or enabled based on reachability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple links are set up between non-AP MLD and AP MLD, then communication capacity and bandwidth are improved, but link management complexity increases due to varying communication reachability between links
Solution Approach 1:
The patent implements feedback mechanisms where devices report actual communication reachability status of each link. The system uses this feedback information to dynamically adjust link enabled states, ensuring that the management state reflects the actual communication state. This resolves the contradiction by automating link management based on real-time feedback, reducing manual management complexity while maintaining multi-link communication capacity.
Solution Approach 2:
The patent enables dynamic adjustment of link states based on changing communication conditions. Links can be transitioned between enabled and disabled states according to actual reachability, allowing the system to adapt to varying network conditions. This dynamic approach maintains high communication capacity when links are available while automatically reducing complexity when links become unreachable.
2Reliability
If links are enabled in multi-link setup, then communication availability is improved, but actual communication state may become inconformity with enabled state due to reachability differences
Solution Approach 1:
The system continuously monitors actual communication reachability and feeds this information back to the link management function. When a link's actual state diverges from its enabled state, the feedback triggers automatic adjustment to restore conformity. This ensures high communication availability while maintaining precise state conformity through continuous monitoring and adjustment.
Solution Approach 2:
The patent performs preliminary checks of communication reachability before enabling links. By verifying reachability conditions in advance, the system prevents enabling links that would immediately be in an inconformity state. This preliminary action maintains both communication availability and state conformity precision.
3Productivity
If all M links are set up for multi-link communication, then communication efficiency is improved, but resource waste occurs on links not within communication range
Solution Approach 1:
The patent implements dynamic link management where links are enabled or disabled based on actual communication needs and reachability. This allows the system to maintain high communication efficiency by keeping active only the links that are currently useful and reachable, while disabling others to avoid resource waste. The dynamic adjustment ensures optimal balance between efficiency and resource consumption.
Solution Approach 2:
The system discards (disables) links that are not within communication range or not currently needed, and recovers (enables) them when conditions improve. This approach eliminates resource waste on unusable links while maintaining the capability to utilize them when needed, thus improving overall communication efficiency without permanent resource loss.

AI summary
Embodiments of the present disclosure provide a multi-link communication method. Specifically, a non-AP MLD initiates a multi-link setup between the non-AP MLD and an AP MLD according to communication reachability between a respective non-AP STA affiliated with the non-AP MLD and a respective AP affiliated with the AP MLD corresponding to each of M links to be set up; where M is a positive integer.
