Wireless Sensing Mode Configuration for UE Resource Reporting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless networks lack mechanisms to configure resources and dedicated sensing operations for user equipment (UE), leading to ad hoc implementations that do not support efficient sensing operations.
Innovation Solution
UEs indicate their sensing capabilities to a sensing management function (SnMF) within the core network, receiving sensing configurations that define resources, targets, and reporting formats, enabling UE-based, UE-assisted, or network-based sensing modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If sensing operations are performed without network configuration, then UE can perform ad hoc sensing, but resource utilization and sensing efficiency are poor
Solution Approach 1:
The network performs preliminary configuration of sensing resources, parameters, and reporting formats before UE executes sensing operations. The gNB configures sensingResourceSet, sensingMeasurement, sensingReport, and other parameters in advance through RRC signaling, enabling UE to perform sensing efficiently without ad hoc decisions.
Solution Approach 2:
The system implements feedback mechanisms where UE reports sensing capabilities and measurement results to the network. The gNB configures sensingReport parameters including reportQuantity, reportConfigId, and timing, creating a closed-loop system that optimizes sensing operations based on network requirements and UE capabilities.
2Adaptability or versatility
If multiple sensing configurations are provided, then sensing versatility is improved, but configuration management complexity increases
Solution Approach 1:
The sensing configuration is segmented into multiple independent components including sensingResourceSet, sensingMeasurement, sensingReport, and sensingObject. Each component can be independently configured and activated, allowing the network to provide multiple sensing configurations for different scenarios without managing a monolithic complex configuration.
Solution Approach 2:
The sensing configuration framework is designed to support multiple sensing modes (UE-based, UE-assisted, network-based) and different sensing scenarios through a universal configuration structure. The same configuration parameters can be reused across different sensing operations, reducing management complexity while maintaining versatility.

AI summary
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a sensing configuration associated with a sensing mode, the sensing configuration indicating one or more parameter values that the UE is to use to perform sensing of objects within a detectable range of the UE, and the sensing configurating further indicating a format for providing a sensing report according to the sensing mode. The UE may receive one or more sensing waveforms based at least in part on the sensing configuration. The UE may transmit, to the base station according to the sensing mode, a sensing report indicating information associated with the one or more sensing waveforms.
