Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the sampling rate for cell measurements is increased to improve measurement accuracy, then measurement precision is improved, but the device complexity and processing load increase
Solution Approach 1:
The patent applies dynamics by making the sampling rate adjustable rather than fixed. The system can dynamically change the sampling rate based on mobility conditions, using higher rates when needed for accurate measurements and lower rates when mobility is minimal, thus balancing measurement precision with processing complexity
Solution Approach 2:
The patent changes the parameter of sampling rate to optimize the balance between measurement accuracy and processing load. By varying this parameter based on mobility detection, the system achieves high measurement precision when necessary while reducing complexity during stable conditions
2Reliability
If mobility related parameters are not accurately determined due to sampling rate variations, then handover decisions become inaccurate causing service interruptions, but increasing sampling rate reduces measurement accuracy for mobility parameter determination
Solution Approach 1:
The patent implements feedback by continuously monitoring measurement results and using this information to adjust mobility related parameters. The system feeds back measurement data to refine handover decisions, ensuring accuracy despite sampling rate variations
Solution Approach 2:
The patent applies preliminary action by pre-configuring multiple mobility related parameters with different sampling rates before actual handover events occur. This allows the system to have ready-to-use parameter sets that can be quickly applied when handover conditions are met, reducing decision time while maintaining accuracy
3Measurement precision
If multiple antenna panels are used to improve coverage and measurement accuracy, then measurement precision is improved, but the device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the antenna system into multiple independent panels, each capable of performing measurements separately. This allows the system to manage complexity through modular architecture while maintaining improved measurement precision through combined data from multiple segments
Solution Approach 2:
The patent makes each antenna panel universal by enabling them to perform multiple functions - both measurement and potential handover execution. This multi-functionality reduces overall system complexity by eliminating dedicated components while maintaining measurement precision through the universal capability of each panel
