Solution Overview

Problem

Existing wireless communication networks face challenges in coordinating transmission opportunities between access points with different channel configurations, leading to increased interference and resource inefficiencies.

Innovation Solution

Access points communicate coordination information via a primary channel, allowing them to coordinate transmission opportunities and reduce interference by indicating their primary channel, even when operating with different primary channels.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If access points use different primary channels for coordination, then channel utilization flexibility is improved, but interference between access points increases

Engineering Contradiction:
Improvechannel configuration flexibilityVSAvoidinterference
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a primary channel as an intermediary communication medium that allows access points with different channel configurations to exchange coordination information. The primary channel acts as a common ground where APs can negotiate and coordinate their respective channel assignments, enabling flexible channel utilization while maintaining interference control through structured coordination protocols.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If access points coordinate transmission opportunities, then resource utilization efficiency is improved, but communication complexity increases

Engineering Contradiction:
Improveresource utilization efficiencyVSAvoidcoordination communication complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The coordination process is segmented into distinct phases: primary channel communication for coordination message exchange, followed by allocated transmission opportunities on secondary channels. This segmentation allows complex coordination to be broken down into manageable steps, improving resource utilization efficiency while controlling communication complexity through structured, phased interactions.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Access points perform preliminary coordination communications on the primary channel before actual data transmission occurs. This preliminary action includes exchanging coordination messages, negotiating resource allocations, and establishing transmission opportunities in advance, which streamlines the subsequent data transmission phase and improves overall resource utilization efficiency.

Inventive Principle:
Principle #10Preliminary action

3Productivity

If access points use same primary channel for coordination, then coordination efficiency is improved, but channel contention increases

Engineering Contradiction:
Improvecoordination efficiencyVSAvoidchannel contention energy
Core Design Contradiction:
ProductivityVSLoss of energy

Solution Approach 1:

The patent implements periodic coordination messages exchanged on the primary channel at scheduled intervals. This periodic action allows multiple access points to efficiently share the primary channel for coordination purposes by using structured time slots and periodic exchanges, improving coordination efficiency while reducing energy waste from continuous contention through organized, interval-based communication.

Inventive Principle:
Principle #19Periodic action

AI summary

This disclosure provides methods, components, devices and systems for operations between access points with different channel configurations. Some aspects more specifically relate to coordination between access points for allocating transmission opportunities when the access points may use the same or different primary channels and/or operating bandwidths. In some examples, coordination may include exchanging coordination information for a transmission opportunity via a primary channel when two access points are configured to utilize the same primary channel. In some examples, coordination may include signaling to indicate the primary channel to be used by the first access point, the second access point, or both when the first access point and the second access point are configured to use different primary channels. The respective primary channels may be used to exchange transmission opportunity coordination information.
