Carrier Aggregation Measurement Reporting with Single-Message Consolidation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In LTE-A systems, the existing measurement reporting methods for carrier aggregation result in high signaling costs and inefficient carrier management due to the need for multiple messages to report channel quality of multiple carriers and neighbor cells, which hinders effective handover decisions.
Innovation Solution
The method allows User Equipment (UE) to report measurement information of multiple carriers and frequencies in a single message by using statistical and instantaneous measurement quantities, measurement reference points, and predefined strategies, reducing the number of required messages and simplifying carrier management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple measurement report messages are sent to report channel quality of multiple carriers and neighbor cells, then measurement information completeness is improved, but signaling cost increases
Solution Approach 1:
The patent combines multiple measurement report messages into a single message by merging measurement information from multiple carriers and neighbor cells. The measurement report includes measurement quantities for serving cells and neighbor cells across different carriers, allowing the network to obtain complete measurement information while reducing signaling overhead and message quantity.
2Measurement precision
If multiple measurement report messages are sent for each carrier, then carrier quality assessment accuracy is improved, but system delay increases
Solution Approach 1:
The patent merges measurement reporting for multiple carriers into a single message, reducing the time required for multiple sequential message exchanges. The measurement report contains comprehensive measurement quantities for all configured carriers and neighbor cells, maintaining assessment accuracy while minimizing system delay through consolidated reporting.
3Manufacturing precision
If separate measurement reports are used for each carrier, then carrier management precision is improved, but device complexity increases
Solution Approach 1:
The patent combines measurement information for multiple carriers into a single structured message format. The measurement report includes measurement quantities for serving cells and neighbor cells across different carriers, along with associated identification information. This unified structure simplifies message processing while maintaining the precision needed for carrier management decisions.

AI summary
Provided in the embodiments of the present invention are a measurement reporting method and device in a CA system. The method includes: UE receives the message from the network side; according to the message, the said UE judges the component carriers and/or measurement object whether meet the condition of triggering measurement reporting or not; when result is true, UE reports measurement information of at least one component carrier and/or measurement information of at least one measurement object to the network side by measurement report message. In the invention, the UE can report the measurement information of multiple carriers and/or frequencies together, therefore, it simplifies the reporting process, reduces the system time delay, and makes the network side easier to perform carrier management for LTE-A UE.
