Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If measurement gap is configured for channel measurements in NR network, then measurement accuracy is improved, but network transmission interruption increases
Solution Approach 1:
The patent combines multiple measurement tasks that require measurement gaps into a single shared measurement gap resource. By merging the gap requirements of multiple measurement objects (MOs) and tasks, the system achieves comprehensive channel measurements while reducing the total time spent in measurement gaps, thereby minimizing network transmission interruptions.
Solution Approach 2:
The patent creates a universal measurement gap configuration that serves multiple measurement tasks simultaneously. A single measurement gap is designed to accommodate different measurement objects and tasks through scalable resource allocation, allowing the same gap resource to fulfill multiple measurement functions rather than requiring separate dedicated gaps for each task.
2Reliability
If separate measurement gaps are allocated for each measurement task, then measurement reliability is improved, but wireless resource efficiency deteriorates
Solution Approach 1:
The patent merges multiple separate measurement gap allocations into a single shared measurement gap resource that serves multiple measurement tasks. This consolidation maintains measurement reliability by ensuring adequate measurement opportunities for each task while significantly improving wireless resource efficiency by eliminating redundant gap periods and reducing overall measurement-related transmissions interruptions.
3Productivity
If measurement gap sharing is implemented among multiple tasks, then resource efficiency is improved, but measurement precision may deteriorate
Solution Approach 1:
The patent applies local quality by providing differentiated measurement gap allocations within the shared resource framework. Different measurement tasks receive customized gap allocations based on their specific requirements, ensuring that each task obtains sufficient measurement precision while collectively achieving high resource efficiency through the shared gap structure.
Solution Approach 2:
The patent implements dynamic measurement gap allocation where the sharing ratios and scaling factors can be adjusted based on network conditions, measurement priorities, and task requirements. This dynamic approach allows the system to optimize both resource efficiency and measurement precision adaptively, ensuring that measurement accuracy is maintained even as resource sharing is implemented.
