UAV Waypoint Flight Declaration for Network Handover and Collision Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There are incompatibilities between how flight plans or paths are characterized by wireless communications systems and aviation standards or regulatory entities, leading to network inefficiencies, particularly in supporting communications between unmanned aerial vehicles (UAVs) and wireless communication systems.
Innovation Solution
The system translates between polygon-based flight paths used by aviation standards and waypoint-based flight paths used by wireless communications systems, enabling UAVs to communicate their current and expected positions within approved flight plan sectors, facilitating efficient routing and collision avoidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If volume-based flight declaration is used to support UAV communications, then network coverage and connectivity are improved, but collision avoidance and spacing assurance for multiple UAVs cannot be guaranteed
Solution Approach 1:
The patent segments the continuous volume-based flight declaration into discrete waypoint declarations. Each waypoint represents a specific position in the flight path rather than a continuous volume, allowing the network to track and manage individual UAV positions along approved flight paths while maintaining network coverage.
2Object-affected harmful factors
If waypoint-based flight declaration is implemented, then collision avoidance and spacing are improved, but incompatibility with volume-based flight declaration creates network inefficiencies
Solution Approach 1:
The patent introduces a translation mechanism that acts as an intermediary between the waypoint-based flight declaration system and the existing volume-based flight declaration infrastructure. This translator converts waypoint declarations into volume-based representations, enabling compatibility with existing network systems while maintaining the collision avoidance benefits of waypoint tracking.
3Adaptability or versatility
If continuous volume-based flight declaration is used, then flight path flexibility is maintained, but position tracking precision for collision avoidance deteriorates
Solution Approach 1:
The patent segments the continuous flight path into discrete waypoint positions that can be precisely tracked. Each waypoint provides a specific location marker along the flight path, enabling precise position tracking for collision avoidance while the sequence of waypoints maintains the overall flight path flexibility.

AI summary
Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) (e.g., an unmanned aerial vehicle (UAV)) may receive an approved flight plan including approved flight plan sectors. The UE may also receive a query from a network node, the query including an indication of a subset of the plurality of approved flight plan sectors and a request for a plurality of waypoints of the UE within the indicated subset of the plurality of approved flight plan sectors. The UE may further determine, in response to receiving the query from the network node, a flight path including the plurality of waypoints of the UE for the indicated subset of the plurality of approved flight plan sectors based on the received approved flight plan, and the UE may transmit, to the network node, a flight declaration message including the waypoints of the UE.
