UAV Path Information Granularity Control for Base Station Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing framework in Release 15 does not consider the granularity of path information, leading to potential unsuitability of the path information reported by UAVs for communication control at base stations.
Innovation Solution
A communication apparatus and method that allow for the transmission of path information with adjustable granularity, enabling the base station to request and receive path information from UAVs with specified granularity, ensuring suitability for communication control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If path information is reported by UAVs without considering granularity, then the path information can be transmitted simply, but the path information becomes unsuitable for communication control at base stations
Solution Approach 1:
The patent applies parameter changes by introducing a granularity parameter (first information) that defines the level of detail in path information. The base station can request path information at different granularities (e.g., different waypoint intervals) depending on communication control needs, transforming the fixed-path-information approach into a flexible, parameter-adjustable system that balances transmission simplicity with control suitability
2Measurement precision
If path information with fine granularity is transmitted, then the accuracy for communication control is improved, but the information transmission overhead increases
Solution Approach 1:
The patent implements dynamics by making the path information granularity adjustable and adaptive. The base station dynamically requests appropriate granularity levels based on current communication control requirements, and the UAV dynamically provides path information at the requested granularity. This dynamic adjustment mechanism allows the system to optimize between accuracy and transmission overhead in real-time rather than using a fixed granularity level
3Quantity of substance
If path information with coarse granularity is transmitted, then the information transmission overhead is reduced, but the accuracy for communication control deteriorates
Solution Approach 1:
The patent resolves this contradiction by introducing granularity as a controllable parameter. The base station can adjust the granularity parameter based on communication control needs - using coarser granularity when high accuracy is not required to reduce overhead, and finer granularity when higher accuracy is needed. This parameter-based approach allows flexible trade-off management between transmission efficiency and control accuracy

AI summary
A communication apparatus includes: a memory storing a program; and one or more processors configured to execute the program to: obtain path information including first information for indicating each of a plurality of waypoints; transmit, to a base station, a message of the completion of a radio resource control, RRC, connection reconfiguration, the message including information for indicating an availability of the path information; receive, from the base station, a UEInformationRequest message including second information used for configuring a granularity of the first information; and transmit in response to the reception of the UEInformationRequest message, to the base station, a UEInformationResponse message including the path information including the first information on a basis of the second information.
