UE Direct DAA Link Setup Based on UAV Capability Check
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The communication procedures and actions for direct communication between a UAV and UE operating as an area airspace manager (AAM) are unclear when the UAV does not support the Detect-And-Avoid (DAA) function, particularly regarding information transmission and processing.
Innovation Solution
User equipment (UE) equipped with a transmission and/or reception unit and a controller that receives identification information from a network or UAV, determining whether to establish a communication path based on the UAV's DAA capability, initiating or not initiating the communication path setup accordingly.

Engineering Contradiction Analysis
1Ease of operation
If the UE initiates a procedure for establishing a communication path for direct communication with a UAV regardless of DAA support status, then the communication path establishment procedure is simplified, but incorrect communication paths may be established with UAVs that do not support DAA
Solution Approach 1:
The UE performs preliminary action by receiving and processing capability information from the UAV before initiating the communication path establishment procedure. The UE checks whether the UAV supports DAA functionality in advance, and only initiates the direct communication path establishment procedure when the UAV is confirmed to support DAA. This preliminary verification ensures that communication paths are only established with compatible UAVs, preventing incorrect pairings while maintaining a streamlined procedure for supported devices.
2Reliability
If the UE checks capability information before establishing communication path, then DAA compatibility is ensured, but the communication procedure becomes more complex
Solution Approach 1:
The capability information message serves multiple functions: it acts as both a standard communication setup message and a capability verification mechanism. By embedding DAA support status within the existing capability information exchange framework, the system achieves reliable compatibility checking without adding separate complex verification procedures. This multi-functional approach ensures DAA compatibility while keeping the overall communication procedure streamlined and manageable.
3Reliability
If capability information exchange is implemented, then appropriate processing is ensured, but information transmission overhead increases
Solution Approach 1:
The capability information exchange is merged with the existing direct communication establishment procedure. The capability information that indicates DAA support is transmitted within the same message framework already used for setting up direct communication between UE and UAV. This consolidation ensures accurate processing of DAA compatibility while avoiding the overhead of separate dedicated capability verification messages, as the information is efficiently packaged within the existing communication setup exchange.

AI summary
A user equipment (UE) operates as an area airspace manager (AAM) to receive information, regarding Detect-And-Avoid (DAA) support of an uncrewed aerial vehicle (UAV), transmitted from the UAV or a network. A technique to perform appropriate processing of an establishment of a direct communication path for the DAA support with the UAV based on the reception of the information.
