Cell Measurement Reporting for Macro-Small Cell Trigger Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Redundant measurement reports increase network load in wireless communication systems with dual connection and multi-stream connections, leading to increased radio resource occupation and network load.
Innovation Solution
Implement a cell measurement reporting method that includes independent measurement and reporting for macro and small cells, defining new trigger events (A7, A8, A9) for small cells, and configuring separate measurement objects for each cell type to reduce redundant reporting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If measurement reporting is performed for both macro cells and small cells using the same measurement objects and trigger events, then measurement coverage is improved, but redundant measurement reports increase network load
Solution Approach 1:
The patent segments measurement objects into separate types: MeasObject for macro cells and MeasObjectSecondaryLink for small cells. This segmentation allows independent configuration and reporting for each cell type, preventing redundant measurement reports while maintaining comprehensive measurement coverage. The UE performs measurements based on the specific cell type and reports only when relevant trigger events are satisfied.
Solution Approach 2:
The patent applies local quality by defining cell-specific trigger events: Event A1-A6 for macro cells and Event A7-A9 for small cells. Each event type has customized threshold comparisons and reporting conditions appropriate to its cell type. For example, Event A7 specifically compares small cell signal quality against macro cell signal quality with an offset, providing localized measurement logic that reduces unnecessary reporting.
2Quantity of substance
If separate measurement objects are configured for macro and small cells, then redundant reporting is reduced, but device complexity increases
Solution Approach 1:
The patent implements universality by creating a unified measurement framework that handles both macro and small cells through standardized procedures. The UE uses the same measurement execution logic and report generation mechanisms for both cell types, differing only in the specific measurement objects and trigger events applied. This multi-functionality approach reduces device complexity despite the increased configuration scope.

AI summary
The present invention provides a cell measurement reporting method and a related device and system. The method includes: receiving, by user equipment, measurement configuration information configured by a network side, and selecting a serving cell according to the measurement configuration information; and measuring, by the user equipment, the selected serving cell according to the measurement configuration information, and when determining that a measurement result of the serving cell meets the trigger event, sending, by the user equipment to the network side according to an indication of the measurement configuration information, a measurement report that carries the trigger event; or measuring, by the user equipment, the serving cell and a neighboring cell, where the neighboring cell is a cell on a carrier frequency indicated by a measurement object associated with the serving cell, and when determining that a measurement result of the serving cell and a measurement result of the neighboring cell meet a preset trigger event, sending, by the user equipment to the network side according to an indication of the measurement configuration information, a measurement report that carries the trigger event; or measuring, by the user equipment, a neighboring cell, and when determining that a measurement result of the neighboring cell meets a trigger event, sending, by the user equipment to the network side according to an indication of the measurement configuration information, a measurement report that carries the trigger event. Therefore, a prior-art problem that redundant measurement reports increase network load when a measurement event is reported is resolved.
