Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional link budget estimation methods are used, then the estimation process is simple, but the accuracy of link budget estimation is insufficient
Solution Approach 1:
The patent performs preliminary analysis of the radio beam power profile and determination of radio channel characteristics before final link budget estimation. By preparing these intermediate results in advance, the system achieves more accurate estimation without requiring complex real-time calculations during the actual link budget determination.
Solution Approach 2:
The patent introduces intermediate parameters such as radio beam power profile analysis results and radio channel characteristics as mediators between the raw power level measurements and the final link budget estimation. These intermediaries enable more accurate estimation by capturing important intermediate information that would be lost in direct estimation methods.
2Reliability
If accurate link budget estimation is achieved through detailed analysis, then communication reliability improves, but calculation complexity increases
Solution Approach 1:
The patent segments the link budget estimation process into distinct stages: receiving power level information, analyzing radio beam power profile, determining radio channel characteristics, calculating optimum radio beam gain, and estimating link budget. This segmentation allows each stage to be optimized independently, improving overall reliability without requiring the entire system to be overly complex.
Solution Approach 2:
The patent performs preliminary analysis of power profiles and channel characteristics before final estimation, preparing data structures and intermediate results that improve reliability while reducing the computational burden during the actual link budget calculation phase.
3Productivity
If optimum radio beam gain is calculated based on detailed channel characteristics, then beam management efficiency improves, but processing time increases
Solution Approach 1:
The patent calculates the optimum radio beam gain based on pre-determined channel characteristics and power profile analysis. By performing these calculations in advance based on already-analyzed data, the system achieves efficient beam management without requiring time-consuming real-time analysis during beam switching operations.
Solution Approach 2:
The patent uses the analyzed power profile and channel characteristics as feedback to determine the optimum beam gain. This feedback mechanism allows the system to adapt beam parameters based on actual measured conditions while using previously gathered data, improving efficiency without requiring complete re-analysis for each beam adjustment.
