Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a fixed correspondence between carriers and power amplifiers is used, then the device complexity is reduced, but the average work efficiency of power amplifiers deteriorates
Solution Approach 1:
The patent implements dynamic adjustment of the correspondence between carriers and power amplifiers based on real-time transmit power changes. The system monitors power variations and reconfigures the carrier-power amplifier mapping to maintain optimal operating conditions, transforming a static fixed correspondence into a dynamic adaptive system that responds to changing operational requirements.
Solution Approach 2:
The system changes the operational parameters of the power amplifiers by adjusting which carriers are assigned to which power amplifiers based on transmit power levels. When transmit power changes exceed threshold values, the system recalculates and reassigns the correspondence to ensure power amplifiers operate in their high-efficiency regions, thereby improving overall average work efficiency.
2Ease of operation
If proper power amplifiers are not flexibly selected according to transmit power changes, then the ease of operation is improved, but the use of energy by stationary object deteriorates
Solution Approach 1:
The system employs feedback mechanisms by continuously monitoring transmit power changes and using this information to adjust the carrier-power amplifier correspondence. The feedback loop detects when transmit power variations exceed predetermined thresholds and automatically triggers reconfiguration, ensuring power amplifiers are always assigned to carriers in an energy-optimal manner without requiring manual intervention.
Solution Approach 2:
The system performs self-optimization by automatically detecting transmit power changes and reconfiguring the carrier-power amplifier mapping without external control. The base station autonomously monitors its own operational parameters and adjusts the correspondence to minimize energy consumption, enabling the system to serve itself in maintaining optimal efficiency.
