1Measurement precision

If power boosting schemes are implemented for RF-S operations, then sensing accuracy is improved, but interference to communication systems increases

Engineering Contradiction:

Improvesensing accuracyVSAvoidinterference to communication systems

Core Design Contradiction:

Measurement precisionVSObject-generated harmful factors

Solution Approach 1:

The patent implements dynamic power adjustment where the sensing management component receives feedback about communication interference and adjusts the power boost level accordingly. The system transitions from static power allocation to dynamic power control, adapting the RF-S transmission power based on real-time communication system status and sensing requirements.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes the power parameter of RF-S signals by implementing power boosting schemes where the sensing management component determines appropriate power boost levels. The power ramping scheme further modifies this by gradually increasing power levels based on sensing needs and interference conditions, optimizing the balance between sensing accuracy and communication interference.

2Area of stationary object

If power ramping schemes are used to enhance sensing signal transmission, then sensing coverage area is increased, but energy consumption increases

Engineering Contradiction:

Improvesensing coverage areaVSAvoidenergy consumption

Core Design Contradiction:

Area of stationary objectVSUse of energy by moving object

Solution Approach 1:

The power ramping scheme implements partial action by gradually increasing power levels only when and where needed for sensing operations. Instead of maintaining high power continuously across all areas, the system ramps up power selectively based on detected sensing requirements and target object positions, reducing overall energy consumption while maintaining adequate coverage.

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

The system employs periodic power adjustments through the power ramping scheme, where power levels are increased in stages rather than continuously. The sensing management component periodically evaluates sensing performance and adjusts power levels accordingly, creating a rhythm of power escalation that balances coverage expansion with energy conservation.

Inventive Principle:

Principle #19Periodic action
