Conditional UE Selection for Resource-Aware Radio Sensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Identifying appropriate UE nodes for participation in network-based or SL-based radio sensing tasks is challenging due to limited UE computation, memory storage, energy resources, synchronization precision, and mobility, which are crucial for tasks like obstacle detection and relative positioning in environments with high-density UE presence.
Innovation Solution
A method for identifying suitable UE nodes for radio sensing operations by transmitting a query message with suitability conditions, receiving a response, and configuring these nodes for radio sensing tasks based on their capabilities and network requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If UEs are selected for radio sensing operations, then sensing coverage and distributed computation resources are enhanced, but device complexity and resource consumption increase
Solution Approach 1:
The network node performs preliminary actions by sending query messages to candidate UEs before selecting them for sensing operations. The UEs evaluate their suitability conditions in advance and respond with their capabilities, allowing the network to make informed selection decisions without forcing UEs to participate in operations they cannot support
Solution Approach 2:
The patent changes the parameter of UE participation from mandatory to conditional by introducing suitability conditions. These conditions include computation capability, memory storage, energy resources, synchronization precision, and mobility parameters. The network selects UEs based on whether they meet these parameter thresholds, thereby enhancing sensing coverage only with capable devices without overloading them
2Productivity
If UEs with limited resources are used for sensing, then device availability increases, but measurement precision and reliability deteriorate
Solution Approach 1:
The patent introduces minimum threshold parameters for measurement precision, synchronization accuracy, and resource availability that UEs must meet to be selected. This ensures that even though many UEs are available, only those meeting the precision thresholds are chosen for sensing operations, maintaining measurement quality while maximizing device availability
Solution Approach 2:
The two-way communication between network and UE provides feedback mechanisms. The network queries UE capabilities, and UEs provide feedback on their suitability conditions. This feedback loop ensures that selected UEs have the necessary precision and resources, preventing selection of inadequate devices while maintaining high availability
3Reliability
If suitability conditions are evaluated for each UE, then sensing operation reliability improves, but network signaling overhead and time consumption increase
Solution Approach 1:
The patent applies partial action by evaluating only the necessary suitability conditions for each UE rather than comprehensive checks. The network sends query messages with specific suitability criteria, and UEs respond only with relevant capability information. This partial evaluation approach maintains sensing operation reliability by checking critical parameters without wasting time on unnecessary assessments

AI summary
Apparatuses, methods, and systems are disclosed for configuring participation in a radio sensing operation. One method includes receiving, from a network node, a query message for a radio sensing operation, where the query message indicates a set of suitability conditions. The method includes determining whether the candidate device satisfies the set of suitability conditions and transmitting, to the network node, a response message to the network node based on the determination. The method includes receiving a sensing configuration for the radio sensing operation in response to the response message, the sensing configuration comprising one or more of: a configuration for radio sensing RS transmission, a configuration for radio sensing RS reception, or a configuration for radio sensing measurement report transmission. The method includes performing the radio sensing operation based on the sensing configuration.
