Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless telecommunications networks face challenges in balancing connection quality and UE battery life due to varying licensed carriers across regions, which complicates carrier aggregation and increases network load and power consumption.
Innovation Solution
The implementation of a system that ranks and selects carrier groups based on availability and region-specific licenses to optimize carrier aggregation, minimizing the need for additional carrier additions and balancing throughput and battery life by using prioritized carrier groups.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If carrier aggregation is performed across regions with diverse licensed carriers, then connection quality and throughput are improved, but network load and power consumption increase
Solution Approach 1:
The patent segments the carrier aggregation process into region-specific carrier groups, where each region has its own licensed carriers. The system divides carriers into primary carrier groups for basic connectivity and secondary carrier groups for enhanced throughput, allowing selective activation based on regional licensing and network conditions. This segmentation enables the system to maintain connection quality while reducing unnecessary power consumption by not aggregating all available carriers simultaneously.
Solution Approach 2:
The system dynamically selects and activates carrier groups based on real-time network conditions, regional licensing constraints, and UE requirements. The base station can flexibly configure which carrier groups are active for each UE, adjusting the level of carrier aggregation dynamically. This dynamic approach allows the system to optimize the balance between connection quality and power consumption by activating only the necessary carriers rather than maintaining all carriers in aggregate state.
2Productivity
If carrier aggregation is performed across regions with diverse licensed carriers, then throughput is improved, but network load increases
Solution Approach 1:
The patent implements local quality by creating region-specific carrier group configurations tailored to each geographic region's licensed carriers. Each region has its own optimized carrier group structure based on local licensing agreements and network conditions. This allows the system to achieve high throughput in each region using only the carriers licensed for that region, rather than attempting to aggregate carriers across all regions, thereby reducing overall network load while maintaining local throughput performance.
Solution Approach 2:
The system applies partial action by selectively activating only the necessary carrier groups required to meet UE throughput requirements, rather than activating all available carriers. The base station assesses the minimum carrier aggregation needed for each UE and activates only those carrier groups, leaving other carriers in a lower-power state. This partial activation approach achieves sufficient throughput while significantly reducing network load and resource consumption.
3Loss of time
If region-specific carrier groups are implemented, then carrier aggregation frequency is reduced, but system complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring region-specific carrier groups before UEs need carrier aggregation. The network maintains predefined carrier group configurations for each region based on licensed carriers and historical performance data. When a UE enters a region, the base station can quickly assign the appropriate pre-configured carrier group without needing to perform complex real-time carrier selection and aggregation calculations. This preliminary configuration reduces the frequency of carrier aggregation operations and minimizes the computational complexity at the time of actual carrier aggregation events.

AI summary
A system described herein may provide a technique for performing carrier aggregation in a wireless telecommunications network in a manner that accounts for (a) diverse licenses for different carriers across different regions, (b) network considerations in minimizing the number of times carrier aggregation is performed, and (c) user equipment (“UE”) considerations in maximizing battery life by utilizing only the carriers that are necessary to utilize. A smallest carrier (or group of carriers) may be identified as a default carriers, and other carriers or groups of carriers may be ranked in descending order, according to size. The ranked list may be iteratively used when performing carrier aggregation, in which the largest available carrier (or group of carriers) from the list may be used for carrier aggregation.
