Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal performs sensing over all time slots (full sensing), then transmission reliability is improved, but energy consumption increases
Solution Approach 1:
The patent applies partial sensing by having the terminal sense only during DRX active durations instead of all time slots. The network configures sensing time windows that align with DRX cycles, allowing the terminal to perform sensing operations only when awake and active, thereby reducing energy consumption while maintaining adequate transmission reliability through selective sensing of critical time periods
2Use of energy by moving object
If the terminal performs sensing over part of time slots (partial sensing), then energy saving is achieved, but transmission reliability may deteriorate
Solution Approach 1:
The patent implements dynamic sensing configuration where the network configures sensing time windows that adapt to DRX parameters. The sensing opportunities are dynamically aligned with active durations based on DRX cycle length, on-duration, and offset values, allowing the system to optimize the balance between energy saving and transmission reliability based on actual communication patterns and channel conditions
Solution Approach 2:
The system employs feedback mechanisms where the network configures sensing parameters based on observed transmission patterns and channel conditions. The sensing time window configuration is adjusted according to feedback about actual transmission reliability requirements and energy consumption patterns, enabling continuous optimization of the partial sensing approach
