Dynamic TID Link Mapping for Wi-Fi Multi-Link Latency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Wi-Fi technologies face challenges in managing traffic identification (TID) mapping across multiple frequency bands, leading to increased access latency and power consumption due to uneven load distribution across links.
Innovation Solution
A method for communication under multiple links that involves determining and transmitting a message frame indicating changes to TID mappings, allowing for dynamic adjustment of link usage based on load and latency conditions, thereby optimizing link utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If TID mapping is statically configured across multiple links, then link management is simple, but access latency increases and power consumption rises due to uneven load distribution
Solution Approach 1:
The patent implements dynamic TID-link mapping adjustment through a feedback mechanism. The AP monitors link load conditions and dynamically remaps TIDs to appropriate links based on current status, transforming the static mapping into a dynamic adaptive system that responds to changing network conditions, thereby reducing access latency while maintaining manageable complexity
2Device complexity
If TID mapping is statically configured across multiple links, then link management is simple, but power consumption increases due to uneven load distribution
Solution Approach 1:
The system dynamically adjusts TID-link mappings based on real-time load monitoring. When links become unbalanced, the AP remaps TIDs to distribute traffic evenly, preventing energy waste from overloaded links and idle underutilized links, thereby optimizing power consumption while keeping management complexity manageable through automated feedback control
3Loss of time
If dynamic TID mapping adjustment is implemented, then access latency and power consumption are reduced, but system complexity increases
Solution Approach 1:
The patent employs a feedback mechanism where the AP continuously monitors link load conditions and automatically adjusts TID mappings in response. This feedback loop enables the system to adapt dynamically to changing conditions, reducing access latency and power consumption while managing complexity through automated control rather than manual configuration
Solution Approach 2:
The system performs self-adjustment of TID mappings through automated load monitoring and remapping operations. The AP independently manages the dynamic reconfiguration without requiring external intervention, enabling the system to optimize its own performance and reduce complexity overhead through autonomous operation
4Use of energy by moving object
If dynamic TID mapping adjustment is implemented, then power consumption is reduced, but system complexity increases
Solution Approach 1:
Through continuous monitoring of link load and automatic TID remapping based on feedback signals, the system optimizes power consumption by directing traffic away from overloaded links. The feedback mechanism manages complexity by providing automated decision-making rules that reduce power waste without requiring complex manual management
Solution Approach 2:
The system autonomously manages its own load balancing and power optimization through self-service mechanisms. The AP independently monitors conditions and performs TID remapping to optimize energy efficiency, reducing power consumption while managing complexity through self-contained automated operations
