Wireless Measurement Reporting Triggering Conditions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication systems face challenges in defining triggering conditions for measurement reports based on various reference signals, particularly in Coordinated Multi-Point (CoMP) environments, where accurate channel status information is crucial for efficient network management.
Innovation Solution
A method for performing measurement reports by user equipment (UE) in a wireless communication system, involving the reception of channel status information-reference signals (CSI-RSs) from multiple sets, determining CSI-RSs that satisfy specific quality-based triggering conditions, and reporting measurement results, which includes continuously transmitting reports until certain conditions are met or a maximum number of transmissions is reached.

Engineering Contradiction Analysis
1Measurement precision
If measurement reports are continuously transmitted to ensure accurate channel status information, then network performance and accuracy are improved, but transmission overhead and resource consumption increase
Solution Approach 1:
The measurement report transmission is made dynamic by introducing triggering conditions based on reception quality thresholds. Instead of continuous transmission, reports are sent only when CSI-RS reception quality changes exceed predetermined offsets, adapting the transmission behavior to actual channel conditions and reducing unnecessary energy consumption while maintaining measurement accuracy.
Solution Approach 2:
The invention changes the transmission parameter from continuous to event-triggered based on reception quality parameters. By monitoring whether CSI-RS reception quality satisfies triggering conditions (comparing against threshold + offset), the system dynamically adjusts transmission frequency, thereby reducing energy loss while preserving measurement precision when needed.
2Measurement precision
If multiple CSI-RS sets are monitored to improve reception quality identification, then measurement accuracy is improved, but device complexity and processing overhead increase
Solution Approach 1:
The invention segments CSI-RS resources into multiple sets (first set and second set) with different configurations. The UE processes each set separately, determining whether CSI-RS from the first set satisfy triggering conditions relative to the second set. This segmentation reduces processing complexity by organizing measurements into manageable groups while maintaining accurate reception quality identification across diverse network environments including CoMP.

AI summary
One embodiment of the present invention relates to a method for a terminal carrying out a measurement report in a wireless communication system, and more particularly, to a method for carrying out a measurement report comprising the steps of: receiving a plurality of CSI-RSs which are included in a first set and/or a second set; determining a CSI-RS that is determined and/or a measurement report on the CSI-RS which is included in the second set, wherein the triggering condition is to be larger than that resulting from applying a predetermined offset to a reception quality value of the specific CSI-RS from the second set.
