Solution Approach 1:

The patent implements dynamic node switching where the sensing receiving node transitions from a first sensing transmitting node to a second sensing transmitting node based on real-time signal quality assessment. This dynamic adaptation allows the system to maintain optimal signal quality while preserving connection stability through structured handover procedures including configuration information transmission and measurement-based decision making.

Inventive Principle:

Solution Approach 2:

The patent employs feedback mechanisms where the sensing receiving node measures signal quality from multiple sensing transmitting nodes and uses this measurement information to determine handover timing. The system continuously monitors signal conditions and provides feedback to trigger appropriate node switching actions, ensuring both signal quality maintenance and connection stability.

Inventive Principle:
Principle #23Feedback

2Object-affected harmful factors

Solution Approach 1:

The patent implements preliminary action by having the sensing receiving node obtain configuration information for multiple sensing transmitting nodes in advance, including the second sensing transmitting node. Measurement configurations are pre-established so that when handover conditions are met, the transition can execute smoothly without service disruption. This preparatory setup ensures both signal quality maintenance and service continuity.

Inventive Principle:

Solution Approach 2:

The patent ensures continuity of useful action through structured handover procedures where the sensing receiving node maintains measurement capabilities across node transitions. The configuration information and measurement configurations enable seamless switching between sensing transmitting nodes, preserving the continuous sensing service while adapting to changing signal conditions.

Inventive Principle:

Solution Approach 1:

The patent implements self-service by enabling the sensing receiving node to autonomously perform measurements on sensing reference signals from multiple sensing transmitting nodes and independently determine handover timing based on predefined conditions. The node uses its own measurement results to trigger handovers without requiring complex centralized control, reducing overall system complexity while maintaining service continuity.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent manages complexity through parameter-based handover decisions where the sensing receiving node monitors specific parameters such as signal quality thresholds and handover conditions. By basing switching decisions on measurable parameters rather than complex algorithms, the system achieves service continuity with manageable device complexity.
