Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If uniform power settings are used for all signals, then device complexity is reduced, but communication efficiency and interference management deteriorate
Solution Approach 1:
The patent segments power control into different types (first power setting for first signals, second power setting for second signals) based on resource allocation patterns. This allows differentiated power management for different communication scenarios without requiring complete redesign of the power control system, thus improving communication efficiency while maintaining manageable complexity.
Solution Approach 2:
The patent implements dynamic power control where power settings are determined based on resource allocation configurations. The control node dynamically selects between different power settings (first and second power settings) depending on whether time resources or frequency resources are allocated, enabling adaptive power management that optimizes communication efficiency without excessive complexity.
2Productivity
If dynamic power allocation is implemented for all resource types, then communication efficiency is improved, but device complexity increases
Solution Approach 1:
The patent applies different power control strategies to different resource types locally. Time resources and frequency resources have different power allocation characteristics, so the system applies appropriate power settings (first power setting for time-based resources, second power setting for frequency-based resources) to each resource type according to its specific requirements, optimizing efficiency without requiring uniform complex control across all resources.
Solution Approach 2:
The patent changes the power control parameter (power setting) based on the resource allocation type. By determining which power setting to use based on whether time or frequency resources are allocated, the system adapts power parameters to match resource characteristics, improving power management efficiency while keeping the control mechanism relatively simple through parameter selection rather than complex computation.
3Reliability
If higher power is allocated to all signals, then signal strength and reliability are improved, but energy consumption and interference increase
Solution Approach 1:
The patent applies partial power allocation where not all signals receive maximum power. Instead, the system selectively applies appropriate power levels based on resource allocation and communication needs, avoiding excessive power consumption while ensuring sufficient power for reliable communication. This partial action approach optimizes the balance between reliability and energy efficiency.
Solution Approach 2:
The patent dynamically changes power parameters based on resource allocation types and communication scenarios. By selecting between different power settings according to whether time or frequency resources are used, the system optimizes power consumption while maintaining adequate signal strength and reliability, preventing both energy waste and insufficient power allocation.
