Solution Overview

Problem

Existing wireless communication systems face issues with unnecessary control measures when addressing radio wave interference, as they do not consider temporal and spatial consecutiveness of the interference.

Innovation Solution

A wireless communication system that includes an interference detection mechanism, an interference analysis unit that estimates the consecutiveness of interference, and a wireless resource control unit that adjusts resources based on the analysis to minimize unnecessary control.

VSEngineering Contradiction Analysis

1Reliability

If control measures are executed for every detected interference, then interference influence is reduced, but unnecessary control execution increases

Engineering Contradiction:

Improveinterference reduction effectivenessVSAvoidcontrol execution efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The system performs preliminary analysis of interference consecutiveness (temporal and spatial patterns) before executing control measures. By evaluating whether interference occurs continuously across multiple time slots and spatial locations, the system determines in advance whether control execution is necessary, thereby avoiding unnecessary control actions while maintaining effective interference suppression when truly needed

Inventive Principle:

Principle #10Preliminary action

2Reliability

If control measures are executed frequently, then interference influence is reduced, but system overhead increases

Engineering Contradiction:

Improveinterference reduction effectivenessVSAvoidcontrol processing time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary analysis of interference consecutiveness patterns before executing control measures. By evaluating whether interference occurs continuously across multiple time slots and spatial locations, the system determines in advance whether control execution is necessary, thereby avoiding unnecessary control actions and reducing processing time overhead

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

Instead of executing control measures for every single interference detection event, the system applies a threshold-based approach where control is only executed when interference demonstrates consistent temporal and spatial patterns exceeding predetermined thresholds. This partial action approach filters out isolated false alarms while maintaining effective suppression of genuine continuous interference

Inventive Principle:

Principle #16Partial or excessive action
