Multicarrier Measurement Reporting for Throughput Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In dual carrier cellular networks, wireless communication devices typically report measurement based only on the primary carrier, leading to suboptimal handover decisions when the secondary carrier is affected by interference or high loading, resulting in reduced overall throughput.
Innovation Solution
Implementing enhanced measurement event reporting that derives a combined measurement from both the primary and secondary carriers, reflecting aggregate throughput and quality, to inform handover decisions and improve overall network performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If measurement reporting is based only on the primary carrier, then the reporting mechanism remains simple and the network can quickly process reports, but the overall throughput is reduced when the secondary carrier is impacted by interference or high loading
Solution Approach 1:
The patent combines measurement reports from multiple carriers (primary and secondary) into a single integrated measurement report. The measurement reporting module aggregates channel quality indicators, signal strength, and other metrics from all configured carriers to create a comprehensive view of network conditions, enabling the device to evaluate overall throughput potential before initiating data transfers.
Solution Approach 2:
The device performs measurements on all configured carriers before initiating data transfer sessions. By conducting preliminary measurements on both primary and secondary carriers and incorporating these results into handover decisions, the network can proactively select optimal carrier configurations that maximize throughput before the actual data transmission begins.
2Reliability
If the device relies on primary carrier quality for handover decisions, then handover decisions can be made quickly based on available measurement data, but the device may remain stuck with a dual carrier pair where the secondary carrier provides low throughput
Solution Approach 1:
The measurement reporting module continuously monitors channel quality metrics from all configured carriers and feeds this information back to the network. This feedback mechanism includes aggregated measurements that reflect the actual throughput potential of the carrier configuration, enabling the network to make more accurate handover decisions and transition devices to optimal carrier pairs when necessary.
Solution Approach 2:
The patent implements dynamic measurement reporting that adapts to changing network conditions. The device can adjust which carriers to measure, how frequently to report, and what metrics to prioritize based on current throughput conditions, interference levels, and network load, allowing for flexible and responsive handover decision-making.
3Productivity
If dual carrier cells are configured to support higher throughput, then data transfer rates can be increased, but the system becomes more complex and requires coordinated management of multiple carriers
Solution Approach 1:
The measurement reporting module is designed to handle multiple carrier types and configurations universally. It can measure and report on primary carriers, secondary carriers, and various frequency bands using the same measurement framework and processing logic, simplifying the management of diverse carrier configurations while maintaining the ability to optimize throughput across different network scenarios.
