Sensing Signal Configuration for Consistent Terminal-Base Station Messaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In future mobile communication systems like B5G and 6G, inconsistent understandings between terminals and base stations regarding sensing signal formats and requirements lead to ineffective sensing signals that fail to meet specific sensing needs.
Innovation Solution
A first device communicates its sensing requirements to a second device, which determines and configures the appropriate signal parameters for a first signal, ensuring uniformity and adherence to the specific sensing needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If each device independently determines sensing signal parameters, then devices can operate autonomously, but signal format inconsistencies arise between terminals and base stations
Solution Approach 1:
The base station acts as an intermediary that receives sensing requirements from terminals, determines appropriate sensing signal parameters, and configures these parameters uniformly. This mediator role ensures that terminals and base stations have consistent understandings of signal formats while preserving terminal autonomy to express their sensing needs.
Solution Approach 2:
Instead of terminals independently determining signal parameters (bottom-up approach), the base station determines parameters based on terminal requirements (top-down approach). This inversion of the determination direction resolves the inconsistency problem while maintaining system-wide uniformity.
2Reliability
If sensing signal parameters are standardized uniformly, then signal consistency is improved, but adaptability to diverse sensing requirements decreases
Solution Approach 1:
The sensing signal parameters are made dynamic rather than fixed. The base station determines and configures parameters adaptively based on the specific sensing requirements of different terminals, allowing the system to maintain uniformity in the determination process while adapting to diverse sensing needs through flexible parameter selection.
Solution Approach 2:
The system changes parameters based on sensing requirements. The base station selects appropriate signal format parameters (such as time-frequency resources, waveform characteristics) according to the specific sensing needs indicated by terminals,从而实现 both consistency in determination and adaptability in fulfillment.
3Adaptability or versatility
If multiple devices determine signal configurations independently, then device flexibility is maintained, but non-uniform signal types and parameters cause transmission issues
Solution Approach 1:
The base station serves as a central coordinator that receives flexibility expressions from multiple terminals, determines unified signal configurations, and distributes these configurations to all involved devices. This ensures that while terminals maintain flexibility in expressing their needs, the actual signal configurations remain uniform across the system.
