Reference Signal Resource Unit Segmentation for Beam Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing reference signal measurement information reporting solution in mobile communications is inefficient, requiring excessive channel resources and not optimized for high-frequency band communication systems like New Radio (NR), where beam management is critical for optimal beam determination between base stations and terminals.
Innovation Solution
A method where a network node maps reference signals to resource units, which are further divided into sub-resource units, allowing terminals to selectively report measurement information based on configuration, reducing the quantity of channel resources used for reporting by focusing on specific sub-resource units with similar or associated reference signal characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the terminal reports measurement information for all resource units, then the beam management accuracy is improved, but the channel resources occupied by reported measurement information increase excessively
Solution Approach 1:
The patent divides resource units into sub-resource units with similar or associated reference signal characteristics. Instead of reporting measurement information for all resource units individually, the terminal reports only for sub-resource units, reducing the quantity of reported data while maintaining beam management accuracy through the segmentation of measurement reporting.
Solution Approach 2:
The patent merges measurement information reporting for sub-resource units that have similar or associated reference signal characteristics. By combining the reporting requirements for multiple sub-resource units with similar characteristics into a single reporting action, the system reduces the total channel resources consumed while preserving the necessary measurement accuracy for beam management.
2Reliability
If the terminal reports measurement information for all resource units, then the beam determination completeness is improved, but the communication efficiency decreases
Solution Approach 1:
The patent segments the measurement reporting process by dividing resource units into sub-resource units with similar characteristics. This segmentation allows the terminal to report only for necessary sub-resource units, maintaining beam determination completeness while improving communication efficiency by reducing the overall reporting burden.
Solution Approach 2:
The patent applies partial action by requiring the terminal to report measurement information only for sub-resource units with similar or associated reference signal characteristics, rather than all resource units. This partial reporting approach maintains sufficient beam determination completeness while significantly improving communication efficiency by avoiding excessive reporting.
3Measurement precision
If the network configures detailed measurement reporting for all resource units, then the measurement information accuracy is improved, but the channel resource consumption increases
Solution Approach 1:
The patent segments the measurement reporting configuration into sub-resource units with similar or associated reference signal characteristics. The network configures measurement reporting at the sub-resource unit level, which maintains measurement information accuracy for beam management while reducing channel resource consumption by avoiding detailed reporting for all individual resource units.
Solution Approach 2:
The patent applies local quality by configuring measurement reporting requirements differently at the sub-resource unit level based on their reference signal characteristics. Instead of uniform detailed reporting across all resource units, the system configures reporting selectively for sub-resource units with similar characteristics, maintaining local measurement accuracy while optimizing overall channel resource usage.
