Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If transmit power reporting is not sufficiently studied, then device complexity is reduced, but coverage is reduced and communication quality degrades
Solution Approach 1:
The patent implements a feedback mechanism where the terminal reports transmit power information to the base station, and the base station adjusts downlink transmission parameters based on this feedback. This closed-loop feedback system enables the network to optimize coverage and communication quality by continuously monitoring and adjusting transmit power levels.
Solution Approach 2:
The patent changes the parameter of transmit power reporting by introducing a reporting mechanism that provides detailed information about terminal transmit power levels, power headroom, and power backoff to the base station. This parameter change enables the network to make more informed decisions about resource allocation and coverage optimization.
2Productivity
If transmit power reporting is not sufficiently studied, then device complexity is reduced, but throughput is reduced
Solution Approach 1:
The patent uses feedback mechanisms where the terminal reports transmit power status and the base station adjusts downlink transmission accordingly. This feedback loop enables dynamic optimization of throughput by matching transmission parameters to actual channel conditions and power availability.
Solution Approach 2:
The patent implements preliminary reporting of power headroom and power backoff information before actual data transmission occurs. This allows the base station to pre-adjust transmission parameters and allocate resources optimally, avoiding throughput degradation that would result from reactive adjustments.
3Reliability
If transmit power reporting is not sufficiently studied, then device complexity is reduced, but communication quality degrades
Solution Approach 1:
The patent implements a feedback mechanism where the terminal reports transmit power information including power headroom and power backoff, enabling the base station to adjust downlink transmission parameters. This feedback loop maintains communication quality by continuously optimizing transmission based on actual power conditions.
Solution Approach 2:
The patent introduces dynamic transmission parameter adjustment based on reported power conditions. The base station dynamically modifies downlink power levels, modulation schemes, and resource allocation in response to terminal power status, ensuring communication quality adapts to changing conditions.
