Solution Overview

Problem

Existing Wi-Fi technologies face challenges in managing and coordinating multiple frequency bands for low-latency communication, particularly in associating a Non-AP MLD with a newly added affiliated AP, which affects regional throughput.

Innovation Solution

A method and apparatus for a Non-AP MLD to detect a beacon frame from an AP MLD indicating a newly added affiliated AP, obtain parameter information, and send a target wireless frame to re-establish a link with the AP MLD, using frames like reassociation request frames to facilitate association.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If an AP MLD adds a new affiliated AP dynamically, then the system adaptability and spectrum utilization are improved, but the complexity of link management and association procedures increases for Non-AP MLD

Engineering Contradiction:

Improvesystem adaptabilityVSAvoidlink management complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The Non-AP MLD performs preliminary actions by detecting the beacon frame in advance to identify newly added affiliated APs before attempting association. This early detection allows the device to prepare association requests with appropriate parameter information, streamlining the subsequent association process and reducing management complexity

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements feedback mechanisms where the Non-AP MLD continuously monitors beacon frames from the AP MLD to receive updates about newly added affiliated APs. This feedback loop enables dynamic adaptation to network changes without requiring complex manual configuration or intervention

Inventive Principle:

Principle #23Feedback

2Productivity

If a Non-AP MLD establishes multi-link communication with AP MLD, then the regional throughput is improved, but the difficulty of detecting and managing newly added affiliated APs increases

Engineering Contradiction:

Improveregional throughputVSAvoiddetection difficulty

Core Design Contradiction:

ProductivityVSDifficulty of detecting and measuring

Solution Approach 1:

The Non-AP MLD utilizes feedback from beacon frames to automatically detect newly added affiliated APs. The beacon frame serves as a feedback mechanism that provides real-time information about network topology changes, enabling the Non-AP MLD to identify and associate with new affiliated APs without increasing detection difficulty

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The Non-AP MLD performs self-service by autonomously detecting beacon frames, identifying newly added affiliated APs, and initiating association procedures independently. This self-service capability allows the device to adapt to network changes automatically, maintaining high throughput without requiring complex external management or intervention

Inventive Principle:

Principle #25Self-service
