Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensing operations are performed continuously to maintain sensing performance, then sensing reliability is improved, but energy consumption increases
Solution Approach 1:
The patent applies dynamics by making the sensing operation mode adjustable and adaptive. The sensing node can dynamically switch between different sensing modes (e.g., first sensing mode with higher reliability and second sensing mode with lower reliability) based on network conditions and energy availability. This dynamic adaptation allows the system to optimize the balance between sensing reliability and energy consumption in real-time.
Solution Approach 2:
The patent changes operational parameters by introducing multiple sensing modes with different parameter sets. Each sensing mode has specific parameters for transmission timing, reception timing, and operational duration that can be adjusted. By changing these parameters according to system conditions, the patent enables optimization of both reliability and energy consumption without compromising the other.
2Measurement precision
If transmission and reception operations are performed frequently to ensure sensing accuracy, then sensing precision is improved, but power consumption increases
Solution Approach 1:
The patent applies partial action by implementing selective transmission and reception operations. Instead of continuous full-duplex operation, the system performs transmission and reception only when necessary and for limited durations. The sensing node can choose to perform partial sensing operations that provide sufficient accuracy without the full energy cost of continuous operations, thereby optimizing the trade-off between precision and power consumption.

AI summary
Aspects of the disclosure are directed to determination of one or more sensing parameters for a sensing session based on an energy saving mode (e.g., a network energy saving (NES) mode) of the sensing node. In some aspects, the one or more sensing parameters are adapted from a set of sensing parameters indicated by a sensing configuration (e.g., the sensing configuration provides sensing parameters which are modified by the sensing node based on dynamic conditions such as DRX/DTX ON/OFF states), or the one or more sensing parameters are selected from a set of candidate sensing parameters indicated by the sensing configuration (e.g., the sensing configuration provides sensing parameter options that the sensing node may select based on dynamic conditions such as DRX/DTX ON/OFF states).
