Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If zero-energy terminals use traditional cell selection and reselection methods designed for legacy terminals, then mobility management can be achieved, but the terminals cannot effectively account for their unique energy harvesting and backscatter capabilities, leading to suboptimal performance
Solution Approach 1:
The patent applies local quality by introducing capability-specific parameters and measurement adjustments tailored to zero-energy terminals' unique characteristics. Different terminals receive customized measurement configurations based on their energy harvesting and backscatter capabilities, ensuring each terminal operates optimally for its specific constraints rather than using a one-size-fits-all approach.
Solution Approach 2:
The patent implements parameter changes by modifying measurement parameters and thresholds specifically for zero-energy terminals. The network device configures adjusted measurement parameters that account for the terminals' limited energy availability and backscatter communication constraints, enabling reliable mobility management adapted to these specialized devices.
2Ease of operation
If zero-energy terminals implement full mobility management functions like legacy terminals, then comprehensive cell selection and reselection can be performed, but the complexity and energy requirements exceed what zero-energy terminals can sustain
Solution Approach 1:
The patent extracts and relocates complex mobility management processing from the zero-energy terminal to the network device. The terminal performs simplified measurements and reports, while the network device handles complex decision-making, parameter configuration, and optimization, significantly reducing terminal complexity and energy consumption while maintaining full mobility management functionality.
Solution Approach 2:
The patent introduces the network device as an intermediary that mediates between the zero-energy terminal and the mobility management system. The network device receives measurement reports from terminals, processes mobility management decisions, and provides optimized configurations, thereby shielding terminals from complexity while enabling comprehensive mobility control.
3Productivity
If zero-energy terminals use standard measurement parameters for cell selection, then compatibility with legacy systems is maintained, but the parameters do not account for energy harvesting variability and backscatter limitations
Solution Approach 1:
The patent applies preliminary action by having the network device pre-configure optimized measurement parameters and thresholds before zero-energy terminals perform cell selection and reselection. These pre-configured parameters account for energy harvesting variability and backscatter limitations, enabling terminals to make informed decisions without needing to process complex real-time adjustments.
Solution Approach 2:
The patent implements feedback mechanisms where zero-energy terminals report measurement results and capability information to the network device, which then adjusts and re-configures parameters based on observed performance and energy availability. This closed-loop feedback ensures parameters remain optimized for varying terminal conditions while maintaining system-wide compatibility.
