Wireless Device Measurement Reporting via Multi-Condition Triggering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication networks are limited in their ability to accurately determine whether to perform handover of a UE from one cell to another by only considering a single measurement quantity, such as RSRP or RSRQ, which can lead to inefficient reporting and increased battery consumption, as well as complex procedures in network nodes.
Innovation Solution
The implementation of a method where a wireless communication device receives instructions from a network node to report measurements only when multiple conditions, such as RSRP and RSRQ, are met, allowing for more precise evaluation of signal quality and reducing unnecessary reporting and battery consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single measurement quantity (e.g., RSRP or RSRQ) is used for handover decisions, then the procedure is simple, but the accuracy of handover decisions is insufficient
Solution Approach 1:
The patent combines multiple measurement quantities (RSRP and RSRQ) into a single unified measurement condition. The network node configures the UE to evaluate both RSRP and RSRQ simultaneously, and only triggers measurement reporting when both conditions are satisfied. This merging approach improves handover decision accuracy by considering multiple signal quality metrics without requiring separate reporting procedures for each quantity.
2Measurement precision
If multiple measurement conditions are required for reporting, then measurement accuracy improves, but UE battery consumption increases
Solution Approach 1:
The patent merges multiple measurement conditions into a single reporting trigger mechanism. Instead of requiring separate reporting for RSRP and RSRQ, the UE evaluates both conditions simultaneously and reports only when both are satisfied. This approach maintains high measurement accuracy while reducing battery consumption by avoiding redundant separate reporting procedures and reducing the total number of reports transmitted.
Solution Approach 2:
The UE autonomously evaluates multiple measurement conditions locally before triggering a report. The device performs self-assessment of whether both RSRP and RSRQ conditions are met, and only initiates reporting when both conditions are satisfied. This self-service mechanism eliminates the need for continuous network monitoring and reduces unnecessary reporting, thereby conserving UE battery energy.
3Measurement precision
If multiple measurement conditions are evaluated, then reporting precision improves, but signaling overhead increases
Solution Approach 1:
The patent combines multiple measurement conditions into a single measurement report configuration. The network node configures the UE to evaluate both RSRP and RSRQ conditions and trigger a single reporting event when both are satisfied. This merging reduces signaling overhead by eliminating the need for separate RRC signaling messages for each measurement quantity, while maintaining high reporting precision through multi-condition evaluation.
