Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If conventional radio resource management is used without considering power amplifier features, then service traffic can be handled, but power amplifier utilization is low and energy consumption is high
Solution Approach 1:
The patent changes the operating parameters of the power amplifier dynamically by adjusting its working state according to traffic conditions and power amplifier feature information, enabling it to operate in high-efficiency regions and reduce energy consumption while improving utilization
Solution Approach 2:
The patent implements a feedback mechanism where power amplifier feature information is obtained and used to adjust radio resource scheduling decisions, creating a closed-loop system that continuously optimizes power amplifier operation based on its actual state
2Power
If power amplifier operates in low load region, then service traffic is handled, but conversion efficiency is low
Solution Approach 1:
The patent makes the power amplifier operation dynamic by adjusting its working state in real-time based on traffic conditions and feature information, allowing it to transition between different efficiency regions and maintain high conversion efficiency while handling service traffic
Solution Approach 2:
The patent changes operational parameters including power amplifier working state and radio resource allocation to shift operation from low-efficiency regions to high-efficiency regions, improving conversion efficiency without sacrificing service traffic handling capability
3Productivity
If power amplifier feature is not recognized and managed, then system operation is simple, but utilization rate is low
Solution Approach 1:
The patent introduces feedback mechanisms to recognize and manage power amplifier features, using obtained feature information to guide scheduling decisions, thereby improving utilization rate while managing complexity through systematic approaches
4Loss of energy
If non-real-time services are scheduled without considering power amplifier efficiency, then scheduling is simple, but energy efficiency is poor
Solution Approach 1:
The patent changes scheduling parameters for non-real-time services based on power amplifier feature information and efficiency regions, optimizing energy efficiency by adjusting when and how these services are scheduled without significantly increasing complexity
Solution Approach 2:
The patent applies different scheduling strategies to different service types, treating non-real-time services differently from real-time services by scheduling them in high-efficiency regions when possible, improving energy efficiency with targeted rather than universal complexity
