Carrier Aggregation Configuration Using UE and Network Capability Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network configurations for carrier aggregation are inefficient as they prioritize component carriers based on bandwidth without considering load, leading to overloading of some carriers and underutilization of others, resulting in reduced throughput and spectral efficiency for user equipment (UEs).
Innovation Solution
Determine carrier aggregation configurations for UEs based on their capabilities and the network's capabilities, using device data such as per call measurement data to identify make, model, and software combinations, and network data to optimize component carrier usage, thereby preventing overloading and improving spectral efficiency.

Engineering Contradiction Analysis
1Quantity of substance
If component carriers are prioritized based on bandwidth, then available bandwidth is maximized, but carrier load distribution deteriorates causing overloading and underutilization
Solution Approach 1:
The patent changes the prioritization parameter from bandwidth alone to a composite metric that includes both bandwidth and load distribution characteristics. By evaluating component carriers on multiple parameters simultaneously, the system achieves balanced load distribution while maintaining adequate bandwidth availability across all carriers.
Solution Approach 2:
The patent implements dynamic carrier prioritization where the selection of component carriers is continuously adjusted based on real-time network conditions and UE capabilities. This dynamic approach allows the system to optimize both bandwidth utilization and load distribution adaptively rather than relying on static bandwidth-based prioritization.
2Ease of operation
If generalized network configurations are used, then configuration simplicity is maintained, but spectral efficiency deteriorates due to inefficient carrier usage
Solution Approach 1:
The patent applies local quality by tailoring carrier aggregation configurations to specific UE capabilities and network conditions rather than using a one-size-fits-all approach. Each UE receives customized configuration based on its supported frequency bands, carrier aggregation capabilities, and the current network state, thereby optimizing spectral efficiency for each local scenario.
Solution Approach 2:
The patent performs preliminary analysis of UE capabilities and network conditions before configuring carrier aggregation. By pre-evaluating which component carriers are available, their bandwidths, and current loads, the system can proactively select optimal carrier combinations that maximize spectral efficiency before data transmission begins.
3Productivity
If per call measurement data is collected and analyzed, then carrier aggregation optimization is achieved, but data processing complexity increases
Solution Approach 1:
The patent extracts only the essential information needed for carrier aggregation optimization from the per call measurement data. Rather than processing all available data, the system selectively extracts key parameters such as throughput measurements, latency values, and carrier utilization metrics that are directly relevant to optimizing carrier selection and configuration.
Solution Approach 2:
The patent implements feedback mechanisms where per call measurement data is continuously collected, analyzed, and used to adjust carrier aggregation configurations. The system processes measurement results to generate optimization recommendations that are fed back into the network configuration, creating a closed-loop system that continuously improves carrier aggregation performance.
