Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If scheduling restrictions are applied to perform network measurements, then measurement accuracy is improved, but data reception efficiency deteriorates
Solution Approach 1:
The patent divides the receive elements into separate functional groups: a first receive element dedicated to network measurements and a second receive element dedicated to downlink data reception. This segmentation allows both functions to operate simultaneously without scheduling restrictions, resolving the contradiction between measurement accuracy and data reception efficiency.
Solution Approach 2:
The patent introduces a spatial dimension by utilizing multiple receive elements with different spatial configurations and beam indices. By operating in different spatial domains simultaneously, the system enables parallel measurement and data reception without time-based scheduling conflicts.
2Productivity
If multiple receive elements are used for simultaneous operations, then productivity is improved, but device complexity increases
Solution Approach 1:
The patent segments the receive elements into distinct functional units with specific spatial configurations, assigning the first receive element for measurements and the second for data reception. This segmentation simplifies the overall system management by creating clear functional boundaries.
Solution Approach 2:
Each receive element is configured with specific local properties (spatial configuration and beam index) optimized for its intended function. The first receive element uses spatial configuration optimized for measurement accuracy, while the second uses configuration optimized for data reception efficiency, allowing independent optimization without affecting the other.
3Measurement precision
If time window configuration is applied, then measurement accuracy is improved, but time efficiency deteriorates
Solution Approach 1:
The patent segments the time window into distinct measurement periods where the first receive element performs network measurements while the second receive element simultaneously receives downlink data. This segmentation enables parallel processing, eliminating the need to choose between measurement accuracy and time efficiency.
Solution Approach 2:
The patent ensures continuous useful action by maintaining simultaneous operations: the first receive element continuously performs measurements while the second receive element continuously receives data throughout the time window, eliminating idle time and maximizing resource utilization.
