Base Station Feature Sequence Mapping for Interference Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communications systems, atmospheric ducting causes ultra-long distance signal transmission with strong signal strength, leading to uplink interference due to downlink signals falling into uplink receive windows, and existing interference source detection methods fail due to different base stations having different mapping rules and bandwidths, resulting in detection errors.
Innovation Solution
A data processing method that determines a transmit parameter for a feature sequence based on a bandwidth greater than a threshold, allowing base stations to send and detect the sequence within their bandwidth range, using a unified mapping rule to improve transmission and detection efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different base stations use different mapping rules and bandwidths for feature sequence transmission, then each base station can operate within its own bandwidth constraints, but feature sequence detection errors occur between base stations
Solution Approach 1:
The patent applies homogeneity by establishing a unified mapping rule for feature sequences across all base stations regardless of their individual bandwidths. The mapping rule uses a standardized formula that generates consistent feature sequences at the same frequency positions for all base stations, ensuring homogeneous detection capability system-wide while allowing each base station to operate within its own bandwidth constraints.
2Productivity
If base stations use larger bandwidths for feature sequence transmission, then transmission and detection efficiency improve, but the transmit and detection periods become longer
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the bandwidth parameter used for feature sequence transmission based on system conditions. By allowing flexible bandwidth selection and using standardized mapping formulas, the system can optimize the balance between transmission efficiency and detection period length, improving overall productivity while managing time loss.
3Loss of time
If base stations use smaller bandwidths for feature sequence transmission, then the transmit and detection periods shorten, but transmission and detection efficiency decrease
Solution Approach 1:
The patent applies universality by creating a mapping rule that works across multiple bandwidth scenarios. The same standardized formula can be applied regardless of the specific bandwidth size, allowing the system to achieve short detection periods with smaller bandwidths while maintaining detection accuracy through the universal mapping approach. This multi-functional mapping rule adapts to different bandwidth configurations without sacrificing efficiency.

AI summary
This application provides a data processing method and an apparatus, to detect an interference source, shorten a transmit period and a detection period of a feature sequence, and improve interference detection efficiency. The method includes: determining, by a first base station, a transmit parameter of a first feature sequence based on a first bandwidth and a preset rule, where the first bandwidth is a bandwidth greater than a threshold in a plurality of base stations; and if a frequency corresponding to the transmit parameter of the first feature sequence falls within a bandwidth range of the first base station, sending, by the first base station, the first feature sequence in the bandwidth range of the first base station, so that when receiving the first feature sequence, a second base station determines, based on the first feature sequence, whether the first base station causes interference to the second base station.
