Reference Signal Event Reporting for CSI-RS and SSB Imbalance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems lack sufficient methods to detect and report coverage issues related to CSI-RS beams compared to SSB beams, leading to sub-optimal coverage areas, downlink interference, and imbalances between uplink and downlink interference, which can result in connectivity issues and capacity problems.
Innovation Solution
Introduce new measurement report triggering events based on measurements of both CSI-RS and SSB reference signals, allowing network nodes to detect and address areas of sub-optimal coverage, downlink interference, and uplink/downlink imbalances by configuring UEs to report on specific events such as CSI-RS and SSB beam status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If measurement reports are triggered based on unbalanced reference signals (CSI-RS and SSB), then detection precision of coverage issues is improved, but device complexity increases
Solution Approach 1:
The patent segments the measurement reporting mechanism into distinct components: separate measurement configurations for CSI-RS and SSB reference signals, independent triggering conditions for each signal type, and differentiated reporting criteria. This segmentation allows the system to achieve high detection precision for various coverage issues while managing complexity through modular design, where each component can be independently configured and optimized.
2Measurement precision
If multiple measurement configurations are implemented for different reference signals, then measurement precision is improved, but ease of operation deteriorates
Solution Approach 1:
The patent implements a universal measurement configuration framework that can handle multiple reference signal types (CSI-RS and SSB) through a single unified mechanism. The measurement configuration includes common parameters such as thresholds, hysteresis, and timing that apply across different signal types, while allowing signal-specific adjustments. This multi-functionality approach maintains high measurement precision for diverse reference signals while simplifying operation through standardized procedures.
3Productivity
If event-triggered measurement reporting is implemented, then productivity is improved, but device complexity increases
Solution Approach 1:
The patent implements dynamic event-triggered measurement reporting where the system automatically adjusts measurement and reporting behavior based on real-time network conditions. The triggering events are dynamically configured based on the current state of CSI-RS and SSB measurements, allowing the system to activate detailed reporting only when coverage issues are detected. This dynamic approach significantly improves productivity by reducing unnecessary reporting overhead while managing complexity through condition-based activation rather than continuous monitoring.
Data Source
AI summary
A communication device can operate in a wireless communication network. The communication device can detect a measurement report triggering event based on a measurement of a first reference signal received by the communication device and based on a measurement of a second reference signal received by the communication device. The first and second reference signals can be different. The communication device can further transmit a measurement report to the wireless communication network responsive to detecting the measurement report triggering event. The measurement report includes at least one of the measurement of the first reference signal and/or the measurement of the second reference signal.
