Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If single parameter measurement is used to determine beam direction, then measurement process is simple, but accuracy is low and noise influence is high
Solution Approach 1:
The patent combines multiple radio frequency signal parameters (RSSI, SINR, RSRP, RSRQ) into a unified decision-making framework. By merging these different parameter measurements into parameter groups and applying voting mechanisms, the system achieves higher measurement precision in determining beam direction while managing the complexity through structured aggregation of multiple data sources.
Solution Approach 2:
The system implements feedback through the voting mechanism where multiple parameter measurements contribute to the final beam direction decision. Each parameter acts as a vote, and the aggregated result provides feedback that improves accuracy by reducing the influence of noise in any single measurement, thus resolving the contradiction between simplicity and precision.
2Measurement precision
If multiple parameter groups are used to select target beam direction, then accuracy is improved, but computational complexity increases
Solution Approach 1:
The patent segments the computational process into distinct stages: obtaining individual parameters, grouping parameters into parameter groups, voting within each group to determine candidate beam directions, and finally selecting the target beam direction. This segmentation reduces computational complexity by breaking down the complex decision-making process into manageable steps while maintaining high accuracy through the structured approach.
Solution Approach 2:
The system uses parameter groups where not all parameters need to be processed to full extent in every scenario. The voting mechanism allows partial evaluation where candidate beam directions are identified through majority vote in parameter groups, and the target beam direction is selected from these candidates, reducing the overall computational burden while maintaining accuracy.
3Productivity
If multiple antenna devices perform beam direction deciding procedure, then system optimization is achieved, but control complexity increases
Solution Approach 1:
The patent implements a universal beam direction deciding procedure that can be applied to multiple antenna devices (first antenna device and second antenna device) using the same methodology. Each antenna device independently performs the same steps: obtaining parameters, forming parameter groups, voting for candidate directions, and selecting target directions. This universal approach optimizes system productivity while managing control complexity through standardized procedures.
Solution Approach 2:
Each antenna device performs its own beam direction deciding procedure independently, determining its own target beam direction based on its received signal measurements. The first antenna device decides its own first target beam direction, and the second antenna device decides its own second target beam direction. This self-service approach enhances system efficiency while reducing control complexity by eliminating the need for centralized coordination of beam direction decisions.
