NR Measurement Reporting With Event-Triggered Cell Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The rapid evolution of 5G New Radio (NR) networks has made efficient measurement reporting mechanisms crucial for maintaining optimal performance and seamless user experiences, but existing systems lack flexible and timely signaling mechanisms for measurement reporting, especially in complex cellular environments.
Innovation Solution
The proposed method involves receiving a radio resource control message with measurement configuration parameters, performing measurements based on these parameters, and transmitting updated measurement reports to the base station, including or excluding specific cells based on configured conditions, thereby optimizing measurement reporting procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If measurement reporting is performed for all cells in the list, then measurement coverage is complete, but signaling overhead and energy consumption increase
Solution Approach 1:
The patent extracts and reports only the necessary measurement results based on event trigger conditions rather than reporting all measurement data. When a specific condition is fulfilled for a subset of cells, only those cells' measurement results are included in the report, while other cells are excluded, thereby reducing signaling overhead and energy consumption while maintaining measurement reliability.
2Productivity
If measurement reporting is performed frequently, then network optimization responsiveness improves, but network energy consumption increases
Solution Approach 1:
The patent implements periodic measurement reporting triggered by event conditions rather than continuous reporting. The terminal equipment performs measurements continuously but only transmits reports when event trigger conditions are met, creating a periodic reporting mechanism that improves responsiveness to network changes while significantly reducing overall energy consumption compared to continuous frequent reporting.
3Loss of information
If all measurement results are included in the report, then reporting completeness is high, but message size and processing overhead increase
Solution Approach 1:
The patent applies local quality by differentiating the treatment of different cells in the measurement report. Instead of uniformly including all cells, the report selectively includes only those cells that meet the event trigger conditions. This localized approach to reporting maintains completeness of relevant information while reducing message size and processing overhead by excluding unnecessary data.
Data Source
AI summary
A method and apparatus for measurement reporting is provided. The method includes receiving from a base station a first radio resource control message, wherein the first radio resource control message comprises a set of parameters for measurement configuration, performing measurement based on the set of parameters for measurement configuration and performing for a measurement identity a set of operations in case that a report configuration associated with the measurement identity contains event trigger configuration, a specific condition is fulfilled for a set of cells, the set of cells is subset of cells of the first list and a specific indication is configured for the report configuration.
