SINR Resource Management for Accurate Beam Reporting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems, particularly 5G NR, lack accurate metrics for predicting transmission performance due to reliance on RSRP alone, which does not consider interference and noise powers, leading to inconsistent beam link performance.
Innovation Solution
Incorporating SINR (Signal-to-Interference-Plus-Noise-Ratio) as a new metric for beam reporting, along with CMR and IMR configurations, to account for interference and noise, and specifying measurement and reporting rules to ensure accurate beam indication and reduced overhead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If RSRP alone is used for beam reporting, then device complexity is reduced, but transmission performance prediction accuracy deteriorates
Solution Approach 1:
The patent combines RSRP measurements with SINR measurements to create a comprehensive beam reporting mechanism. By merging these two metrics, the system achieves accurate transmission performance prediction without excessive complexity, as the standardized measurement and reporting procedures leverage existing infrastructure.
Solution Approach 2:
The patent enables SINR measurements to serve multiple functions: predicting transmission performance, selecting interference measurement resources, and configuring reporting rules. This multi-functionality reduces the need for separate mechanisms, thereby managing device complexity while improving prediction accuracy.
2Measurement precision
If SINR with CMR and IMR configurations is implemented, then transmission performance prediction accuracy is improved, but device complexity increases
Solution Approach 1:
The patent configures CMR and IMR resources in advance through standardized procedures, allowing UEs to perform SINR measurements without real-time complexity. The pre-configuration of measurement resources and reporting rules simplifies the actual measurement process while maintaining high prediction accuracy.
Solution Approach 2:
The patent introduces configurable parameters for SINR reporting, including measurement resource selection and reporting thresholds. These parameter changes allow the system to adapt to different scenarios, improving prediction accuracy while managing complexity through standardized configuration mechanisms.
3Measurement precision
If detailed SINR measurement and reporting rules are specified, then beam indication accuracy is improved, but reporting overhead increases
Solution Approach 1:
The patent implements selective SINR reporting based on configured thresholds and conditions. Instead of reporting all SINR measurements, the system reports only those meeting specific criteria, thereby maintaining beam indication accuracy while reducing reporting overhead through partial action.
Solution Approach 2:
The patent establishes feedback mechanisms where SINR measurement results inform future measurement configurations and reporting decisions. This feedback loop optimizes reporting overhead by adjusting measurement and reporting parameters based on observed conditions, maintaining accuracy while minimizing redundant transmissions.

AI summary
Methods, systems, and devices for resource management for reporting signal-to-interference-plus-noise-ratio (SINR) in mobile communication technology are described. An example method for wireless communication includes transmitting, by a network node to a wireless device, a first resource configuration and a second resource configuration, where the first resource configuration comprises one or more first resources related to channel measurement, the second resource configuration comprises one or more second resources related to interference measurement, and at least one first resource is associated with at least one second resource; and receiving, by the network node, a report comprising one or more SINR values, where at least one SINR value is based on the at least one first resource and the at least one second resource.
