RAN Sensing Management Component for Accurate Low-Latency Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communications systems face network latency issues that affect the accuracy of tracking and reporting changes in the orientation, position, and mobility of objects due to the placement of sensing functions in the core network, which is distant from the target objects.
Innovation Solution
Introduce a Sensing Management Component (SMC) located within the Radio Access Network (RAN) architecture, enabling low latency sensing operations through enhanced communications and signaling between the SMC and the Core Network's Sensing Function (SF), allowing sensing operations to be performed closer to the devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If sensing functions are placed in the core network, then network architecture is simplified, but network latency increases and tracking accuracy deteriorates
Solution Approach 1:
The patent segments the sensing management functionality by introducing a distributed sensing management component at the RAN level, separate from the core network sensing function. This allows sensing operations to be performed locally at the RAN while maintaining core network coordination, thereby reducing latency without oversimplifying the overall architecture.
Solution Approach 2:
The patent adds a new dimensional layer to the network architecture by introducing intermediate sensing management components at the RAN level between the UE and core network. This dimensional addition enables local processing that reduces latency while maintaining core network oversight.
2Extent of automation
If sensing functions are placed in the core network, then centralized control is maintained, but tracking accuracy of object position and orientation deteriorates
Solution Approach 1:
The patent segments sensing management into distributed RAN-level components that perform local sensing operations and core network components that provide centralized coordination. This segmentation enables both local measurement precision and centralized control to coexist.
Solution Approach 2:
The patent introduces intermediate sensing management components at the RAN level that act as mediators between the UE and core network. These intermediaries perform local sensing processing to improve measurement precision while maintaining centralized control through core network coordination.
3Loss of time
If sensing operations are performed closer to devices, then latency is reduced, but network architecture complexity increases
Solution Approach 1:
The patent segments sensing management functions between RAN-level components and core network components, allowing local processing that reduces latency while distributing complexity across multiple levels rather than concentrating it.
Solution Approach 2:
The patent implements dynamic sensing management where the RAN-level sensing management component can independently perform sensing operations and only communicates with the core network when necessary, allowing the system to adapt its complexity based on operational needs.

AI summary
Various aspects of the present disclosure provide a sensing management component (SMC), which can be located or other placed within a radio access network (RAN) architecture, such as within an NG-RAN node or user equipment (UE). The SMC, which may communicate with a sensing function of a core network, enables a wireless communications system to perform certain sensing operations from the RAN node or UE, which are near or proximate to devices (e.g., UEs or base stations) that perform the sensing operations.
