Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current LTE systems do not support single frequency cell aggregation, preventing devices with limited capabilities from utilizing this feature due to the requirement of dual component carrier capabilities, which increases complexity and cost.
Innovation Solution
Defining reduced user equipment capability sets for single frequency cell aggregation, allowing devices to support multiple serving cells on a single carrier resource with a subset of carrier aggregation features, optimizing complexity and cost based on user needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If dual component carrier capabilities are required for cell aggregation, then aggregation performance is improved, but device complexity and cost increase
Solution Approach 1:
The patent segments the carrier aggregation capability into two distinct sets: full dual component carrier capabilities and reduced single frequency capabilities. This segmentation allows devices to select the appropriate capability set based on their complexity and cost constraints, enabling cell aggregation functionality without requiring complete dual component carrier implementation.
Solution Approach 2:
The patent applies local quality by providing different capability sets for different device types. Reduced capability user equipment can implement only the necessary single frequency cell aggregation features while omitting unnecessary dual component carrier features, optimizing the quality and functionality for each specific device category.
2Adaptability or versatility
If all dual component carrier features are implemented, then full aggregation capability is achieved, but device cost increases
Solution Approach 1:
The patent extracts and removes unnecessary dual component carrier features from the reduced capability set, retaining only the essential single frequency cell aggregation functionalities. This extraction eliminates redundant features that would increase device cost, allowing manufacturers to produce lower-cost devices that still provide cell aggregation capability.
Solution Approach 2:
The patent enables a simplified, more economical implementation of cell aggregation by defining reduced capability sets that can be implemented at lower cost. These reduced capability configurations serve as a cost-effective alternative to full dual component carrier implementation, making cell aggregation accessible to a broader range of devices with varying budget constraints.
