Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Traditional wireless communication systems with multiple access-point (AP) devices managed by a central controller lack efficiency and flexibility in coordinating data transmissions among AP devices, especially those in different groups or neighborhoods.

Innovation Solution

A decentralized mechanism where AP devices exchange requests and responses to establish coordination agreements, allowing them to perform coordination transmissions during transmission opportunities (TXOP) based on capability and availability, using transceivers and processors to manage coordination pairs dynamically.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a central controller manages multiple AP devices, then coordination transmission can be organized within groups, but AP devices in different groups or neighborhoods cannot perform coordination transmission

Engineering Contradiction:

Improvecoordination transmission capabilityVSAvoidcentralized management structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent divides the centralized management structure into distributed autonomous AP devices. Each AP device independently manages its own coordination agreements with neighboring APs, eliminating the need for a central controller and enabling cross-group coordination transmission.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Instead of having a central controller manage AP devices top-down, the patent inverts the management approach by enabling bottom-up autonomous coordination. AP devices independently establish coordination agreements with neighbors through direct peer-to-peer communication, allowing flexibility across different groups and neighborhoods.

Inventive Principle:

Principle #13The other way round (Inversion)

2Productivity

If AP devices establish coordination agreements dynamically, then transmission flexibility and efficiency are improved, but management complexity increases

Engineering Contradiction:

Improvedata transmission efficiencyVSAvoidcoordination agreement management

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

AP devices autonomously establish, maintain, and dissolve coordination agreements based on their own transmission needs and capabilities. Each AP independently manages its coordination state without external intervention, reducing overall system management complexity while improving transmission efficiency.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The coordination agreements between AP devices are dynamic rather than static. APs can establish coordination relationships on-demand and dissolve them when no longer needed, allowing the network to adapt flexibly to changing transmission requirements while maintaining simple local management.

Inventive Principle:

Principle #15Dynamics

AI summary

A coordination transmission method is provided. A first request and a first response are exchanged with a second AP, by a first AP. The first request is used for requesting to establish a first coordination agreement between the first AP and the second AP. The first response is used for indicating an allowance or a rejection for establishing the first coordination agreement between the first AP and the second AP. A coordination transmission with the second AP is performed by the first AP, during an opportunity of transmission under a condition that the establishing of the first coordination agreement between the first AP and the second AP is allowed.
