Solution Overview

Problem

Current wireless communication systems face challenges in managing multi-link aggregation efficiently, leading to suboptimal data throughput and spectral efficiency due to limitations in mapping traffic identifiers to wireless links and managing data flows across multiple bands.

Innovation Solution

The implementation of a multi-link operation device that generates messages mapping traffic identifiers to link parameters and processes packets based on these mappings across multiple wireless links, enabling efficient data transmission and reception across multiple bands, thereby improving channel diversity and throughput.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multi-link aggregation is implemented to improve data throughput, then bandwidth capacity increases, but link management complexity increases

Engineering Contradiction:
Improvedata throughputVSAvoidlink management complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent segments traffic identifiers into multiple groups, with each group mapped to a specific wireless link. This segmentation allows independent management of each link while maintaining overall aggregation benefits, reducing the complexity of managing all links uniformly.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a link management entity that acts as an intermediary between the multi-link aggregation protocol and the individual wireless links. This intermediary handles the complex mapping and routing decisions, simplifying the overall system architecture and making link management more tractable.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of energy

If traffic is distributed across multiple wireless links, then spectral efficiency improves, but packet routing complexity increases

Engineering Contradiction:
Improvespectral efficiencyVSAvoidpacket routing complexity
Core Design Contradiction:
Loss of energyVSDevice complexity

Solution Approach 1:

The patent applies local quality by assigning specific traffic identifier groups to specific wireless links based on their characteristics. Each link is optimized for its assigned traffic type, improving spectral efficiency while keeping routing decisions localized and simpler rather than requiring global optimization across all links.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent performs preliminary mapping of traffic identifiers to wireless links during connection establishment. This pre-configuration simplifies real-time packet routing decisions, as the mapping is predetermined and stored, eliminating the need for complex real-time routing calculations.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If multiple bands are used for communication, then channel diversity improves, but system configuration complexity increases

Engineering Contradiction:
Improvechannel diversityVSAvoidsystem configuration complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent creates a universal link identification and mapping mechanism that works across multiple wireless bands and frequencies. This universal approach allows the same traffic identifier to be mapped to different physical links on different bands without requiring separate configuration systems for each band, reducing overall configuration complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)
