Solution Overview

Problem

In wireless communication systems, multiple circuits operating in the same frequency band experience co-frequency interference, affecting communication quality and efficiency due to differing protocols and MAC layers, making it challenging for them to coexist effectively.

Innovation Solution

A method involving a processing module and a co-frequency coexistence confirmation module that acquires and analyzes channel state information to identify co-frequency interference, performing channel reallocation only when interference is detected, thereby reducing interference and improving communication quality and efficiency by ensuring target channels have no co-frequency interference.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple wireless communication circuits operate in the same frequency band simultaneously, then communication coverage and service capability are improved, but co-frequency interference occurs affecting communication quality

Engineering Contradiction:

Improvecommunication coverageVSAvoidco-frequency interference

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The system dynamically changes channel parameters by reallocation. When co-frequency interference is detected between communication paths, the processing module reallocates channels to different frequency sub-bands, transforming the operating parameters to eliminate interference while maintaining simultaneous operation of multiple circuits

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

Different communication paths are assigned to different local frequency resources (channels). The system divides the frequency band into multiple channels and allocates specific channels to specific communication paths, ensuring that each path operates in its own local frequency space without interfering with others

Inventive Principle:

Principle #3Local quality

2Reliability

If channel reallocation is performed continuously to avoid interference, then communication quality is maintained, but circuit resources and energy are wasted

Engineering Contradiction:

Improvecommunication qualityVSAvoidcircuit resource consumption

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The co-frequency coexistence confirmation module performs preliminary detection of co-frequency interference before reallocation is needed. By detecting interference conditions in advance and triggering reallocation only when necessary, the system avoids continuous or unnecessary reallocation operations, thereby saving circuit resources and energy

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system establishes a feedback mechanism where the co-frequency coexistence confirmation module continuously monitors channel states and provides feedback to the processing module. Reallocation is triggered only when the feedback indicates interference exists, creating an on-demand response system that avoids unnecessary operations

Inventive Principle:

Principle #23Feedback

3Loss of energy

If channel reallocation is delayed to save resources, then energy consumption is reduced, but communication quality deteriorates due to persistent interference

Engineering Contradiction:

Improveenergy consumptionVSAvoidcommunication quality

Core Design Contradiction:

Loss of energyVSReliability

Solution Approach 1:

The system performs preliminary detection of interference conditions through the co-frequency coexistence confirmation module before quality deterioration occurs. This early detection enables timely reallocation that prevents quality degradation while avoiding unnecessary reallocation when no interference exists, optimizing the balance between energy consumption and communication quality

Inventive Principle:

Principle #10Preliminary action
