UAV RAN Signaling for Handover and Beam Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication technologies for Unmanned Aerial Vehicles (UAVs) lack clarity in transmitting and receiving UAV-related information, such as flight path and height, across different interfaces in a Radio-Access Network (RAN), which hinders effective handover and beam management.
Innovation Solution
Implementing methods and devices for transmitting and receiving UAV-related information, including flight path and height, over Xn and F1 interfaces between NG-RAN nodes and gNB-CU/gNB-DU, using communication units and processors to facilitate efficient handover and beam management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If UAV-related information is transmitted across RAN interfaces, then handover and beam management are improved, but the complexity of information transmission protocols increases
Solution Approach 1:
The patent applies universality by designing a multi-functional information transmission mechanism that can carry both flight path information and height information through standardized protocol fields. The existing RAN interface protocols are enhanced to accommodate UAV-specific parameters without requiring separate dedicated protocols, thus improving reliability while controlling complexity through multi-functionality.
Solution Approach 2:
The patent segments UAV-related information into distinct parameters (flight path information, height information) that can be transmitted independently or combined. This segmentation allows the system to transmit only necessary information for each specific handover or beam management scenario, reducing unnecessary protocol complexity while maintaining reliability.
2Adaptability or versatility
If detailed UAV flight path and height information is transmitted, then network adaptability for UAV operations is improved, but the quantity of information to be processed increases
Solution Approach 1:
The patent applies local quality by transmitting detailed UAV information (flight path, height) selectively based on specific network conditions and operational requirements. Not all nodes or scenarios receive the complete information set - only those that require it for handover or beam management decisions. This localized information transmission enhances adaptability where needed while reducing overall information processing quantity.
Solution Approach 2:
The patent implements partial action by transmitting subsets of UAV information parameters depending on the specific operational context. For routine operations, only essential parameters are transmitted, while more detailed information is transmitted only when required for complex handover or beam management scenarios, thus balancing adaptability with information processing efficiency.
