Conditional Flight Path Update Triggers for UAV Signaling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems lack efficient mechanisms for updating flight path information in mobile communication networks, particularly in environments where precise location and timing are critical, such as for unmanned aerial vehicles (UAVs).
Innovation Solution
Implementing conditional triggers for flight path update indications based on distance, time, or waypoint thresholds, allowing wireless transmit/receive units (WTRUs) to transmit updated flight path information via UE assistance messages or RRC signaling when specific conditions are met.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If continuous flight path updates are transmitted, then the precision and reliability of wireless communication for UAVs is improved, but the signaling overhead and network traffic increase
Solution Approach 1:
The patent implements periodic flight path updates at configured intervals rather than continuous transmission. The network configures the UAV with a periodicity parameter, and the UAV transmits flight path information at these periodic intervals, reducing signaling overhead while maintaining adequate tracking precision for the application.
Solution Approach 2:
The patent introduces conditional parameters (distance threshold, time-based threshold, waypoint threshold) that control when flight path updates are transmitted. The UAV monitors these parameters and only transmits updates when the thresholds are satisfied, dynamically adjusting transmission based on actual flight conditions rather than using fixed periodic or continuous transmission.
2Quantity of substance
If flight path updates are transmitted only when thresholds are satisfied, then the signaling overhead is reduced, but the response time to critical flight path changes may be delayed
Solution Approach 1:
The patent pre-configures multiple threshold types (distance threshold for spatial deviation, time-based threshold for temporal deviations, waypoint threshold for route changes) that cover different critical flight scenarios. By having multiple pre-set thresholds, the system anticipates various critical conditions and ensures appropriate response timing for each type of deviation without requiring continuous monitoring and decision-making.
3Adaptability or versatility
If multiple threshold types are monitored, then the adaptability of the flight path update mechanism is improved, but the device complexity increases
Solution Approach 1:
The patent segments the flight path monitoring function into distinct threshold types (distance threshold, time-based threshold, waypoint threshold), each handling a specific aspect of flight path deviation. This segmentation allows the complex monitoring task to be divided into manageable, independent sub-functions, reducing the overall system complexity while maintaining comprehensive coverage of critical flight conditions.

AI summary
Systems, methods, devices, and instrumentalities are described herein related to conditional triggers for flight path update indications. A wireless transmit/receive unit (WTRU) may receive configuration information. The configuration information may indicate a trigger condition (e.g., threshold) associated with enabling transmission of a flight path update indication. The WTRU may determine that the threshold associated with enabling transmission of the flight path update indication is satisfied. Based on the threshold being satisfied, the flight path update indication may be transmitted. The WTRU may receive a request to transmit the updated flight path information and transmit the updated flight path information.
