Flight Path Reporting Configuration for Low-Latency UAV Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems lack efficient mechanisms for reporting flight path information in real-time, leading to potential delays and inaccuracies in flight path updates, especially in dynamic environments such as those involving unmanned aerial vehicles (UAVs).
Innovation Solution
A wireless transmit/receive unit (WTRU) is configured to transmit flight path information upon availability, receive a reporting configuration, and periodically update flight path information based on changes, sending indications or acknowledgments as necessary to ensure timely and accurate reporting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If flight path information is reported continuously, then real-time accuracy is improved, but communication overhead and network resources are consumed excessively
Solution Approach 1:
The patent implements periodic flight path reporting where the WTRU transmits updates at configured intervals rather than continuously. The network can configure reporting periodicity to balance real-time accuracy requirements with network resource consumption, allowing the system to update flight path information at optimal intervals without excessive overhead.
Solution Approach 2:
The patent employs feedback mechanisms where the network receives flight path information from the WTRU, processes it, and sends back acknowledgments or control messages. This feedback loop allows the network to adjust reporting requirements dynamically, requesting updates only when necessary and confirming receipt, thereby optimizing the balance between accuracy and resource consumption.
2Loss of time
If flight path updates are transmitted immediately upon change, then response time is improved, but network traffic increases significantly
Solution Approach 1:
The patent applies partial reporting by transmitting only the necessary flight path information changes rather than complete updates. The WTRU can indicate whether flight path information has changed and provide updated data only when needed, reducing network traffic volume while maintaining timely responses to significant changes.
Solution Approach 2:
The WTRU autonomously evaluates whether flight path information has changed since the last report and decides when to transmit updates. This self-service mechanism allows the WTRU to control its own reporting behavior, transmitting immediately when changes occur but avoiding unnecessary transmissions when no changes have happened, thus balancing responsiveness with traffic reduction.
3Measurement precision
If detailed flight path information is reported including timestamps and waypoints, then measurement precision is improved, but message size and processing complexity increase
Solution Approach 1:
The patent segments flight path information into discrete components such as waypoints, timestamps, and status indicators. The WTRU can transmit these segmented pieces of information selectively based on what has changed, allowing detailed reporting when needed while simplifying the process by handling each component independently rather than processing complete complex messages every time.
Data Source
AI summary
Systems, methods, devices, and instrumentalities are described herein relate to explicit requests for flight path statuses. A wireless transmit/receive unit (WTRU) may transmit a first message indicating flight path information is available. The WTRU may receive a second message including a flight path reporting configuration. The flight path reporting configuration may request the flight path information. The flight path reporting configuration may include at least one of: a number of waypoints; whether to include timestamp information; or a configuration to periodically report flight path information updates. The WTRU may transmit an initial flight path message within a third message. At a configured periodicity, the WTRU may evaluate whether the flight path information has changed since a previous flight path report was transmitted.
