Carrier Aggregation Profile Configuration via Geographic Sector Partitioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Configuring a radio access network to improve performance is challenging due to the complexity of numerous radio access nodes with varying characteristics, multiple frequencies, different mobility scenarios, and varying traffic loads, making it difficult to determine optimal frequency bands for carrier aggregation across multiple nodes.
Innovation Solution
A network analysis platform receives and analyzes data from radio access nodes to determine carrier aggregation profiles, including primary and secondary carriers, by partitioning coverage areas into geographic sectors, calculating pathloss values, and determining degrees of contiguous coverage for each frequency band, thereby dynamically configuring carrier aggregation profiles for nodes.

Engineering Contradiction Analysis
1Productivity
If carrier aggregation is configured across multiple radio access nodes with varying characteristics and frequencies, then network throughput and spectral efficiency are improved, but the complexity of network configuration and optimization increases significantly
Solution Approach 1:
The patent segments the network into geographic sectors based on coverage area and partitions frequency bands into different groups (first frequency bands and second frequency bands) with distinct characteristics. This segmentation allows independent optimization of each sector and frequency group, reducing the overall configuration complexity while maintaining high throughput across the entire network.
Solution Approach 2:
The patent applies local quality by selecting different frequency bands for different geographic sectors based on their specific characteristics. Each sector is configured with frequency bands that are optimal for its local conditions (e.g., urban vs. rural areas, coverage requirements), rather than using a uniform configuration across the entire network, thereby improving throughput without requiring complex centralized optimization.
2Productivity
If multiple frequency bands are used for carrier aggregation, then spectral efficiency is improved, but the difficulty of determining optimal frequency bands increases
Solution Approach 1:
The patent performs preliminary classification of frequency bands into first frequency bands (suitable for certain geographic sectors) and second frequency bands (suitable for other sectors) before actual carrier aggregation occurs. This pre-categorization based on frequency characteristics and geographic coverage properties simplifies the real-time selection process and reduces the difficulty of determining optimal frequency bands during network operation.
Solution Approach 2:
The patent introduces geographic sectors as an intermediary framework that mediates between frequency band selection and network configuration. By using geographic sectors as the organizing principle, the system simplifies the complex task of frequency band selection into a more manageable process of matching sectors with appropriate frequency bands based on their characteristics, thereby reducing detection and measurement difficulty.
3Adaptability or versatility
If radio access nodes are configured with different characteristics and mobility scenarios, then network adaptability is improved, but the difficulty of optimizing performance across diverse conditions increases
Solution Approach 1:
The patent segments the network into geographic sectors that can be independently optimized for different mobility scenarios and node characteristics. Each sector can be configured with appropriate frequency bands and parameters tailored to its specific mobility patterns (e.g., high mobility urban areas vs. low mobility rural areas), improving network adaptability while reducing the complexity of optimizing the entire heterogeneous network uniformly.

AI summary
In some implementations, a device may partition a coverage area associated with a network to form one or more geographic sectors, and may determine a pathloss value for each frequency band of multiple frequency bands and a spatial distribution between cells, within the geographic sector, for each frequency band. The device may determine a degree of contiguous coverage for each frequency band within the geographic sector based on the pathloss value and the spatial distribution between cells for that frequency band, and may determine, based on the degree of contiguous coverage for each frequency band, a specific frequency band, of the multiple frequency bands, to be used as a primary carrier for carrier aggregation in the geographic sector. The device may output information that identifies a carrier aggregation profile that indicates the specific frequency band to be used as the primary carrier for carrier aggregation in the geographic sector.
