Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple measurement gaps are configured to improve measurement functionality, then communication accuracy is improved, but device complexity and power consumption increase
Solution Approach 1:
The patent segments measurement gap configuration into multiple independent gap patterns, each associated with specific measurement functionalities. This allows the system to configure and manage multiple measurement gaps separately, improving measurement accuracy for different purposes while maintaining manageable complexity through structured organization of gap configurations.
Solution Approach 2:
The patent implements dynamic gap configuration where the network can activate, deactivate, or modify specific gap patterns based on current measurement needs. This dynamic management allows the system to adapt the number and configuration of measurement gaps in real-time, improving measurement accuracy when needed while reducing complexity and power consumption when fewer measurements are required.
2Measurement precision
If multiple measurement gaps are configured to enhance measurement capabilities, then communication accuracy is improved, but battery life deteriorates
Solution Approach 1:
The patent employs periodic measurement gap patterns where measurements are conducted at scheduled intervals rather than continuously. This periodic action allows the device to maintain measurement accuracy for handover and network selection while keeping the receiver mostly inactive, significantly reducing battery consumption compared to continuous monitoring.
Solution Approach 2:
The system dynamically adjusts the measurement gap configuration based on current network conditions and measurement requirements. When measurement accuracy is critical, the network activates more frequent or extended gap patterns. When conditions are stable, the system reduces measurement frequency, thereby lowering power consumption while maintaining sufficient measurement capability.
3Productivity
If gap functionality is associated with specific measurement gaps to improve operational efficiency, then power management is improved, but configuration complexity increases
Solution Approach 1:
The patent enables a single measurement gap pattern to be associated with multiple different measurement functionalities (e.g., handover measurement, network selection, positioning). This multi-functionality approach improves operational efficiency by consolidating gap usage while managing complexity through a standardized association mechanism that maps functionalities to gap patterns systematically.
Solution Approach 2:
The system segments gap functionality associations into distinct configurations where each measurement functionality can be independently linked to specific gap patterns. This segmentation allows for flexible and efficient power management by activating only the necessary gap configurations for current operations, while the modular structure keeps configuration complexity manageable through clear separation of functionality-gap mappings.
