Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face a challenge in accurately determining whether a communication channel with deteriorated quality can be restored, leading to a potential decrease in communication success rates due to the persistence of interference and changing environmental conditions.
Innovation Solution
A wireless communication system that includes a detection unit to assess communication quality across channels, a deletion unit to remove channels with deteriorated quality, and a determination unit to evaluate the restorability of deleted channels based on neighboring channel data, ensuring accurate restoration and maintaining communication quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a communication channel is deleted when its quality deteriorates, then communication reliability is improved, but communication success rate may decrease due to premature deletion before actual restoration
Solution Approach 1:
The system performs preliminary actions by deleting channels when quality deteriorates and then preliminarily assessing restorability using neighboring channel data before final restoration, preventing premature restoration while avoiding permanent loss of usable channels
Solution Approach 2:
The system implements feedback mechanisms by continuously monitoring communication quality, counting deletion assessments, and using this feedback to determine when restorability assessment should be performed, creating a closed-loop control system that adapts to changing channel conditions
2Device complexity
If restorability is assessed using only deleted channel data, then assessment simplicity is improved, but assessment accuracy deteriorates due to lack of contextual information
Solution Approach 1:
The system uses neighboring communication channels as intermediaries to assess the restorability of deleted channels. By evaluating RSSI values and quality metrics of adjacent channels, the system infers the likely state of the deleted channel without directly measuring it, thereby improving assessment accuracy while maintaining manageable complexity
Solution Approach 2:
The system applies local quality assessment by examining specific neighboring channels (immediate neighbors and potentially extended neighbors) rather than analyzing all channels globally. This localized approach focuses computational resources on the most relevant data points, balancing assessment accuracy with system complexity
3Measurement precision
If all communication channels are monitored continuously, then communication quality detection accuracy is improved, but system energy consumption increases
Solution Approach 1:
The system performs partial monitoring by continuously tracking all channels but only conducting detailed restorability assessments on deleted channels when specific conditions are met (e.g., after a threshold number of quality deteriorations). This partial action approach maintains detection accuracy for all channels while reducing the energy-intensive assessment process to only when necessary
Solution Approach 2:
The system implements periodic assessment cycles where restorability evaluation is triggered after a predetermined number of quality deterioration events rather than continuously. This periodic action reduces energy consumption by performing comprehensive assessments only at intervals when actual restoration is more likely to occur

AI summary
A wireless communication system is configured to detect characteristic data indicating communication quality in the performed wireless communication, for each of the communication channels, delete communication channel, in which deterioration in communication quality is determined based on the characteristic data detected by the detection unit, from the plurality of communication channels used for the wireless communication, and determine, based on the characteristic data of a neighboring communication channel close in frequency to a communication channel that has been deleted by the deletion unit, restorability of the deleted communication channel to the plurality of communication channels used for the wireless communication.
