Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional EMF measurement techniques are used, then measurement process is simple, but measurement accuracy is poor due to network configuration variations
Solution Approach 1:
The system performs preliminary actions by establishing a maximum network throughput connection before EMF measurement, measuring synchronization signals, determining downlink location, and configuring resource blocks. These preliminary steps ensure the network is in a known state, eliminating the need for complex real-time adjustments during measurement and improving accuracy without adding measurement-time complexity.
Solution Approach 2:
The system changes network parameters by configuring the base station to operate at maximum network throughput and selecting specific bandwidth parts and resource blocks for measurement. This standardizes the network state during measurement, ensuring consistent and accurate EMF readings while simplifying the measurement process through parameter control rather than adding complexity.
2Reliability
If network throughput is maximized for measurement, then measurement reliability is improved, but network performance impact increases
Solution Approach 1:
The system applies local quality by configuring maximum network throughput and selecting specific bandwidth parts only for the measurement duration and specific resource blocks, rather than maintaining high throughput continuously. This ensures measurement reliability during the measurement window while minimizing impact on overall network productivity through localized and temporary configuration changes.
Solution Approach 2:
The system uses periodic action by establishing maximum throughput connection and performing measurements in controlled intervals rather than continuously. The measurement process is triggered and executed as a periodic operation, allowing the network to return to normal throughput levels between measurements, thus maintaining reliability without sustained productivity loss.
3Measurement precision
If comprehensive network parameters are measured, then diagnosis accuracy is improved, but measurement time increases
Solution Approach 1:
The system segments the measurement process into distinct phases: establishing maximum throughput connection, measuring synchronization signals, determining downlink location, configuring resource blocks, and performing EMF measurement. This segmentation allows each phase to be optimized independently, achieving comprehensive diagnosis accuracy through structured measurement of specific parameters without the time cost of measuring all possible parameters simultaneously.

AI summary
Improved and accurate electromagnetic field (EMF) measurements of cellular network components such as a base station are performed by establishing a maximum network throughput connection with the desired base station, measuring a synchronization signal between the base station and a user equipment, and determining downlink location (e.g., from System Information Block 1 “SIB1”). Next, a resource block for a basic frame may be configured using timing information of the measured synchronization signal and a bandwidth part (BWP) to be measured in the configured resource block may be selected. The BWP may be selected based on the downlink location in some examples. Alternatively, a BWP corresponding to the maximum traffic may be selected. The EMF measurement may be performed for the configured resource block (selected BWP).
