Terminal Sensing Signal Coordination in B5G Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cellular network technologies face high signaling overheads and delays due to the lack of air interface resource information, which is necessary for configuring sensing signals in B5G networks, leading to inefficient sensing operations.
Innovation Solution
A communication method where a target terminal sends a sensing request to an auxiliary terminal with configuration information, allowing direct coordination of sending and receiving sensing signals between the two terminals, eliminating the need for reporting this information to the network device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the SF or the AMF configures the time-frequency position of the sensing signal, then the sensing function is implemented in the 3GPP network, but the signaling overheads and delay increase due to reporting auxiliary information
Solution Approach 1:
The patent extracts the air interface resource information from the network device and places it directly in the terminal device. This allows the terminal to autonomously determine time-frequency positions for sensing signals without requiring the SF or AMF to configure them, thereby eliminating the need to report auxiliary information and reducing signaling overhead and delay.
Solution Approach 2:
The terminal device is empowered to self-determine the time-frequency positions of sensing signals using locally stored air interface resource information. This self-service capability eliminates dependency on network device configuration and auxiliary information reporting, directly reducing signaling overhead and processing delay while maintaining sensing functionality.
2Extent of automation
If the SF or the AMF configures the time-frequency position of the sensing signal, then the sensing control is centralized, but the signaling overheads increase due to auxiliary information reporting
Solution Approach 1:
The patent extracts air interface resource information from the network device and stores it in the terminal device. This extraction eliminates the need for the terminal to report auxiliary information about time-frequency positions to the SF or AMF, thereby reducing signaling overhead while maintaining automated sensing control through a different mechanism.
Solution Approach 2:
The terminal device uses its own stored air interface resource information to autonomously determine sensing signal parameters, eliminating the need for auxiliary information reporting to network devices. This self-service approach reduces signaling overhead while maintaining sensing automation through terminal autonomy rather than network control.
