Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If power reduction methods are applied to reduce electromagnetic radiation, then human safety is improved, but uplink coverage and communication quality deteriorate
Solution Approach 1:
The patent implements dynamic power control by enabling terminals to adjust their transmission power based on real-time P-MPR indications received from the base station. The terminal monitors the P-MPR values and dynamically modifies its uplink transmission power accordingly, creating a flexible system that adapts to changing conditions rather than using fixed power reduction levels.
Solution Approach 2:
The patent establishes a feedback mechanism where the base station sends P-MPR indication information to the terminal, and the terminal responds by adjusting its transmission power. This closed-loop feedback system allows continuous optimization of the balance between electromagnetic radiation reduction and uplink coverage maintenance, with the base station able to monitor and control terminal power levels based on network conditions.
2Object-affected harmful factors
If transmission power is reduced to ensure safety compliance, then electromagnetic safety is improved, but communication quality deteriorates
Solution Approach 1:
The patent changes the power control parameter by introducing P-MPR (Power Management Power Reduction) as a new control variable. The base station sends P-MPR indication information that specifies the amount of power reduction the terminal should apply, allowing precise control over transmission power levels to meet safety requirements while minimizing impact on communication quality.
Solution Approach 2:
The system dynamically adjusts transmission power based on real-time P-MPR indications rather than using static power reduction. The terminal continuously monitors P-MPR values and adapts its transmission power accordingly, enabling the system to maintain optimal communication quality while ensuring safety compliance under varying network conditions.
