Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If standard user terminals are used for interference detection, then device complexity is reduced, but measurement precision and detection capability deteriorate due to limited capabilities
Solution Approach 1:
A scanner apparatus is introduced as an intermediary device between the communication systems and user terminals. The scanner performs specialized interference detection measurements across frequency bands and reports results to the communication system, enabling precise interference detection without requiring enhanced capabilities in standard user terminals.
Solution Approach 2:
The patent replaces the need for complex user terminal-based interference detection with a dedicated scanner apparatus that performs measurements using carrier-to-interference-noise ratio (CINR) metrics. This substitution transfers the detection function from general-purpose terminals to a specialized measurement device.
2Measurement precision
If comprehensive interference measurement methods are implemented, then measurement precision improves, but ease of operation deteriorates due to cumbersome procedures
Solution Approach 1:
The scanner apparatus autonomously performs interference detection measurements without requiring manual configuration or user intervention. The system automatically scans frequency bands, measures CINR values, identifies interference sources, and categorizes them, making the complex measurement process self-executing and easy to operate.
Solution Approach 2:
The scanner performs preliminary interference measurements and categorizations before user intervention is needed. By pre-identifying and categorizing interference sources (detected, possible, or unknown), the system prepares measurement results in advance, simplifying subsequent analysis and mitigation actions.
3Measurement precision
If detailed interference source identification is performed, then measurement precision improves, but loss of time increases due to extensive analysis requirements
Solution Approach 1:
The interference identification process is segmented into three distinct categories: detected interference sources (clearly identified), possible interference sources (likely but not certain), and unknown interference sources (unidentified). This segmentation enables rapid classification of interference while maintaining precision for identified sources, reducing the time needed for complete analysis.
Solution Approach 2:
The scanner applies different levels of analysis depth to different frequency bands and interference types based on local characteristics. By focusing detailed identification efforts on specific areas with detected interference while using quicker methods for other bands, the system maintains high precision where needed while minimizing overall analysis time.

AI summary
Solutions for interference detection are provided. A frequency band is scanned (200) for transmissions of a transmission system. One or more parameters are determined (202) from the obtained scanning results. At least one determined parameter is compared (204) to a threshold value. On the basis of the comparison it is determined (206) that an unknown transmission exists on a given frequency band. One or more transmission systems are determined (208) which may be the cause of the unknown transmission. At least part of the given frequency band is scanned (210) for transmissions of the determined one or more transmission system; and on the basis of the scanning the system causing the unknown transmission is determined. Information related to the system and transmission parameters of the unknown transmission are decoded (212).
