Aerial User Equipment Flight Path Reporting Using Algebraic Expressions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently managing resources for aerial user equipment (AUEs) due to the lack of precise flightpath information and data efficiency in reporting flightpaths, which affects resource allocation and planning.
Innovation Solution
AUEs transmit flightpath reports including expected geographic locations and uncertainty values, allowing networks to manage resources effectively, and optionally use algebraic expressions or filters to reduce data volume and enhance granularity in reporting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If detailed flightpath information is reported to the network, then resource management precision is improved, but data transmission volume increases
Solution Approach 1:
The patent extracts and reports only the most critical flightpath parameters (expected geographic locations, time values, and uncertainty values) to the network, rather than transmitting complete detailed flightpath data. This selective extraction maintains resource management precision while reducing overall data transmission volume.
Solution Approach 2:
Instead of reporting precise flightpath data and then filtering, the patent inverts the approach by using algebraic expressions to represent flightpaths, which inherently compresses the data while preserving the ability to calculate precise positions when needed for resource management.
2Quantity of substance
If algebraic expressions are used to model flightpaths, then data volume is reduced, but reporting granularity decreases
Solution Approach 1:
The patent changes the representation parameter from discrete waypoint coordinates to continuous algebraic expressions with uncertainty values. This allows the system to maintain fine granularity in position estimation by adjusting the uncertainty parameters while keeping data volume low through compact mathematical formulations.
Solution Approach 2:
The patent adds the uncertainty dimension to the flightpath reporting, transforming simple coordinate data into probabilistic position estimates. This additional dimension enables precise resource management decisions while the algebraic nature of the expressions keeps the data compact.
3Quantity of substance
If filters are applied to flightpath reports, then data volume is decreased, but information completeness is reduced
Solution Approach 1:
The patent performs preliminary processing of flightpath data by applying filters and selecting only relevant portions before transmission to the network. This preliminary action reduces data volume while preserving the essential information needed for resource management, as the filtering criteria are designed to retain only network-relevant flightpath segments.

AI summary
Methods, systems, and devices for wireless communications are described. Aerial user equipments (AUEs) may indicate flightpath information to the network (e.g., to a serving network entity). A network entity may request a flightpath report, which may include a sequence of expected geographic locations. An AUE may include estimated timestamps and uncertainty values associated with each timestamp with the flightpath report. Accordingly, the network may manage communications resources for the AUE accounting for the time and associated uncertainty that the AUE will be at each indicated point along the flightpath. A network entity may indicate a filter to apply to the flightpath report, and accordingly the AUE may report the portion of the flightpath that is relevant to the given network entity. The AUE may report the flightpath using an algebraic expression to reduce the amount of data as compared to a flightpath report that includes a set of waypoints.
