Engineering Contradiction Analysis
1Ease of operation
If static allocation of PAwR parameters and PHY is used, then device complexity is reduced and ease of operation is improved, but resource usage efficiency deteriorates and power consumption increases
Solution Approach 1:
The patent implements dynamic adjustment of PAwR parameters and PHY characteristics based on real-time communication conditions. The system transitions from static allocation to dynamic adaptation, where parameters such as transmission power, data rate, and timing are adjusted according to channel quality, device mobility, and traffic patterns, thereby reducing power consumption while maintaining operational simplicity through automated control
Solution Approach 2:
The system changes physical and operational parameters of the PAwR mechanism in real-time. Specifically, it adjusts transmission power levels, PHY data rates, and timing parameters based on channel conditions and communication requirements. This parameter adaptation enables the system to optimize power usage dynamically without requiring manual intervention, resolving the contradiction between ease of operation and power consumption
