Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If power-saving signal parameters are statically configured, then the configuration is simple, but the flexibility is poor and power consumption is high
Solution Approach 1:
The patent applies dynamics by transitioning from static power-saving signal parameters to dynamic parameters that can be adjusted based on terminal behavior. The base station determines power-saving signal parameters dynamically according to terminal switching behavior between BWPs, allowing the system to adapt to changing conditions and reduce power consumption through optimized monitoring configurations.
Solution Approach 2:
The patent implements parameter changes by modifying power-saving signal parameters based on terminal switching behavior. The base station adjusts parameters such as monitoring occasions, search spaces, and physical downlink control channel configurations dynamically, changing these parameters according to whether the terminal is switching between BWPs to optimize power consumption while maintaining communication efficiency.
2Adaptability or versatility
If power-saving signal parameters are dynamically configured for each BWP, then flexibility is improved, but system complexity increases
Solution Approach 1:
The patent applies local quality by configuring power-saving signal parameters specifically for each BWP based on local switching behavior. Instead of applying a uniform configuration across all BWPs, the base station determines and configures parameters locally for each BWP according to the terminal's switching patterns, allowing optimized power saving in each bandwidth portion while maintaining overall system coordination.
Solution Approach 2:
The patent implements segmentation by dividing the power-saving signal configuration into separate configurations for different BWPs. Each BWP has its own power-saving signal parameters that can be independently determined and configured based on switching behavior, allowing the system to manage complexity through modular, segmented configuration rather than a monolithic approach.
3Loss of energy
If terminal monitors power-saving signal on every BWP switching, then power saving opportunities are maximized, but monitoring overhead increases
Solution Approach 1:
The patent applies partial action by having the terminal monitor power-saving signals selectively rather than continuously on every BWP switch. The base station determines whether power-saving signal monitoring is necessary based on switching behavior, and the terminal performs monitoring only when needed, reducing both power consumption and monitoring time while still capturing power saving opportunities when they are available.
