Solution Approach 1:

BFRS transmission is scheduled periodically with intentional gaps that align with antenna panel displacement periods. The network entity transmits BFRS only when panels are stationary, ensuring detection accuracy while maintaining efficient resource utilization through structured periodic transmission patterns

Inventive Principle:

Solution Approach 1:

The system introduces mechanical displacement information as a new parameter that modifies BFRS transmission timing. By changing the timing parameter based on panel displacement status rather than redesigning the entire beam management architecture, the solution reduces detection latency while keeping system complexity manageable

Inventive Principle:

Solution Approach 1:

The network entity obtains mechanical displacement information in advance and uses it to pre-calculate optimal BFRS transmission timing, ensuring transmissions occur only when antenna panels are in stable positions. This approach eliminates resource wastage from failed detections while maintaining efficient signaling overhead through targeted, timely transmissions
