Solution Overview

Problem

In wireless communication networks, devices continually scan for channels and channel conditions, leading to unnecessary duplication of effort and battery power consumption, especially in environments where devices experience similar channel conditions.

Innovation Solution

Implementing a system where devices can reuse channel maps and designate a primary device to perform channel scanning and share channel condition information with others, reducing redundant scanning and optimizing battery life.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If each device continually scans for channels and channel conditions, then devices can independently obtain accurate channel information, but battery power consumption increases and duplicative scanning occurs

Engineering Contradiction:
Improvechannel condition accuracyVSAvoidbattery power consumption
Core Design Contradiction:
Measurement precisionVSUse of energy by moving object

Solution Approach 1:

Multiple devices that would otherwise independently perform channel scanning are merged into a collaborative system where one device performs scanning and others reuse the results. This combines the scanning function across multiple devices to eliminate duplicative efforts while maintaining accurate channel information availability for all devices in the group.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

Instead of each device creating its own channel map through scanning, devices copy and reuse channel maps generated by other devices in the group. This copying approach maintains measurement accuracy while eliminating the energy-consuming scanning process for devices that don't need to generate their own maps.

Inventive Principle:
Principle #26Copying

2Ease of operation

If each device performs independent channel scanning, then devices can operate autonomously without relying on others, but system efficiency decreases due to redundant scanning operations

Engineering Contradiction:
Improvedevice autonomyVSAvoidsystem efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The channel scanning function is universalized across the device group, where any device can serve as the scanner for the entire group. This multi-functionality allows the system to maintain autonomy (any device can scan if needed) while improving efficiency through coordinated scanning assignments and result sharing among all devices.

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

3Use of energy by moving object

If devices share channel maps, then battery power is conserved by reducing scanning, but devices must trust and rely on information from other devices

Engineering Contradiction:
Improvebattery power consumptionVSAvoidinformation accuracy
Core Design Contradiction:
Use of energy by moving objectVSReliability

Solution Approach 1:

The system implements feedback mechanisms where devices can report channel condition changes or inaccuracies, allowing the group to update and refine shared channel maps. This feedback loop maintains information accuracy and reliability while preserving the energy-saving benefits of map sharing, as devices can request updates only when conditions change rather than continuously scanning.

Inventive Principle:
Principle #23Feedback

AI summary

The present application relates to devices and components including apparatus, systems, and methods to share channel maps between devices for channel selection for connections. A device may perform channel scanning operations for determining channel conditions and generating channel maps, and may provide the channel maps to other devices. The other devices can reduce channel scanning operations based on receiving the channel maps from the device.
