Dynamic Multi-Link WLAN Data Transmission via Contention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multi-link wireless local area network (WLAN) systems face inefficiencies in data transmission due to pre-allocation of links, which can lead to congestion and poor link switching capabilities, resulting in suboptimal data transmission efficiency.
Innovation Solution
A method for data transmission that determines an available link through contention and adds data to its transmission queue, allowing data to be transmitted over multiple links dynamically, with deletion from other queues once transmitted, thereby optimizing link utilization and reducing delay.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If links are pre-allocated for data transmission, then link management is simplified, but data transmission efficiency deteriorates due to congestion and poor link switching capabilities
Solution Approach 1:
The patent implements dynamic link selection where data packets are not bound to pre-allocated links but can be transmitted over any available link determined through contention. This dynamic approach allows the system to adapt to changing network conditions, switch to less congested links automatically, and optimize transmission efficiency without complex manual link management.
2Productivity
If data is transmitted over multiple links, then transmission efficiency is improved, but system complexity increases due to multiple transmission queues and coordination requirements
Solution Approach 1:
The patent segments the transmission system into independent link-level contention mechanisms, where each link maintains its own transmission queue and contention logic. This segmentation allows multiple links to operate independently with simple individual rules, avoiding the need for complex centralized coordination while still achieving efficient multi-link utilization.
3Reliability
If link switching is enabled to avoid congestion, then transmission reliability is improved, but link management complexity increases
Solution Approach 1:
The patent implements a self-service link selection mechanism where data packets autonomously determine which link to use through contention-based access. Each packet independently evaluates link availability and selects appropriate links without requiring complex centralized link management or switching control, thereby achieving reliable transmission through simple distributed decision-making.
