Solution Overview
Problem
Current wireless networking technologies face challenges in efficiently managing and utilizing user equipment (UE) sensing capabilities within wireless networks, particularly in registering and selecting UEs with appropriate sensing capabilities for specific sensing tasks, which affects the effectiveness of sensing services across diverse geographic areas.
Innovation Solution
A method and apparatus that enable user equipment (UE) to transmit sensing capabilities to the core network, allowing registration with sensing services, and for the core network to manage and select UEs based on their capabilities for specific sensing tasks, including monostatic, bistatic, transmission, reception, and sidelink sensing modes, facilitating efficient sensing service provision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user equipment sensing capabilities are not systematically registered and managed, then device complexity is reduced, but sensing service reliability and accuracy deteriorate
Solution Approach 1:
The patent applies preliminary action by requiring UEs to register their sensing capabilities with the network in advance, before actual sensing services are needed. The UE includes sensing capability information in registration requests to the AMF, and the network stores this information for future service matching. This advance registration ensures that when sensing services are required, the network can reliably select appropriate UEs based on pre-verified capabilities, thus improving sensing service reliability without adding complex real-time management overhead.
2Measurement precision
If UE sensing capabilities are not selectively matched to specific sensing tasks, then service provision is simplified, but sensing service accuracy deteriorates
Solution Approach 1:
The patent applies local quality by enabling the network to match specific UE sensing capabilities with specific sensing task requirements. The AMF stores detailed sensing capability information for each UE (including monostatic/bistatic modes, transmission/reception roles, sidelink sensing, and supported sensing signal types) and uses this information to selectively assign UEs to appropriate sensing tasks. This capability-based matching ensures that each sensing task is performed by UEs with the locally optimal capabilities needed for that specific task, thereby improving sensing service accuracy.
3Adaptability or versatility
If comprehensive UE sensing capability information is collected and stored, then sensing service coverage is improved, but information management complexity increases
Solution Approach 1:
The patent applies the extraction principle by separating sensing capability information collection from general UE registration procedures. The system extracts only the necessary sensing capability parameters (sensing modes, roles, sidelink capability, supported signal types) that are relevant for sensing service matching, while ignoring other unrelated UE information. This selective extraction allows the network to maintain comprehensive sensing capability data for service coverage without managing unnecessary information, thus improving sensing service adaptability while minimizing information management overhead.
