Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If additional external measurement equipment is deployed to detect transmission line quality, then measurement capability is improved, but device complexity and ease of operation are worsened
Solution Approach 1:
The 5G radio transceiver system performs self-diagnosis by using its own transmitted reference signals to measure transmission line quality through the feedback data line, eliminating the need for external measurement equipment. The system monitors its own operational status by analyzing the quality of received reference signals against pre-configured thresholds.
2Reliability
If transmission line quality measurement is performed continuously, then reliability is improved, but use of energy and productivity are worsened
Solution Approach 1:
The system performs quality measurement at specific periodic intervals by selecting reference signals from predetermined time slots within the TDD frame structure, rather than continuously monitoring. This periodic measurement approach maintains reliability while reducing energy consumption compared to continuous monitoring.
3Productivity
If measurement is performed during operation, then productivity is improved, but measurement precision and reliability are worsened
Solution Approach 1:
The measurement process is segmented into specific time slots within the TDD frame structure, where reference signals are transmitted and received during designated periods. This segmentation allows the system to perform measurements during operation without interfering with normal data transmission, maintaining both productivity and measurement precision.
