Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems lack efficient mechanisms for updating flight path information in uncrewed aerial vehicles (UAVs) based on predefined thresholds, leading to potential inaccuracies and inefficiencies in navigation.
Innovation Solution
Implementing conditional triggers for flight path update indications in wireless transmit/receive units (WTRUs) that transmit updated flight path information when specific thresholds, such as distance, time, or waypoint thresholds are met, using UE assistance information or RRC signaling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If flight path update indications are transmitted continuously, then navigation accuracy is improved, but communication overhead and energy consumption increase
Solution Approach 1:
The patent implements periodic evaluation of flight path information at configured intervals, where the WTRU determines whether to transmit updates based on whether changes exceed configured thresholds. This periodic action with conditional transmission reduces unnecessary communication compared to continuous transmission, thereby lowering energy consumption while maintaining navigation accuracy when changes are significant.
Solution Approach 2:
The patent introduces configurable parameters including distance thresholds, time thresholds, and evaluation periodicity that allow the system to adapt the transmission behavior. By changing these parameters, the system can balance between navigation accuracy and energy consumption based on specific operational requirements, enabling flexible optimization of the contradiction.
2Measurement precision
If flight path update indications are transmitted frequently, then navigation accuracy is improved, but communication overhead increases
Solution Approach 1:
The patent employs configurable parameters such as distance thresholds, time thresholds, and maximum update frequencies to control transmission behavior. These parameters enable the system to adjust communication overhead based on actual flight path changes, ensuring that updates are transmitted when navigation accuracy requires them while avoiding unnecessary transmissions that would increase communication overhead.
Solution Approach 2:
The system implements feedback mechanisms where the WTRU evaluates whether flight path changes exceed configured thresholds before transmitting updates. This feedback-based decision process ensures that communication overhead is minimized by only transmitting when necessary, while still maintaining navigation accuracy by capturing significant flight path changes.
3Loss of energy
If threshold-based conditional triggers are implemented, then energy efficiency is improved, but device complexity increases
Solution Approach 1:
The patent segments the flight path monitoring function into distinct evaluation components: distance threshold evaluation, time threshold evaluation, and periodic evaluation. Each component independently assesses specific aspects of flight path changes, allowing the system to implement threshold-based conditional triggers in a modular fashion that manages device complexity while achieving energy efficiency.

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.
