Carrier Aggregation Signaling for Component Carrier Management
Solution Overview
Problem
In wireless communication systems with multiple component carriers, existing technologies are inefficient in managing setting information, leading to suboptimal communication performance.
Innovation Solution
The system manages specific and common system information elements for each component carrier using radio resource control signaling, with paging used to update information, allowing mobile stations to determine updates based on value tags, thereby optimizing communication efficiency across multiple carriers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If system information elements are managed separately for each component carrier, then communication efficiency is improved, but device complexity increases
Solution Approach 1:
The patent segments system information elements into specific information (carrier-specific) and common information (shared across carriers). This segmentation allows efficient management by treating different types of information differently, improving communication efficiency while managing complexity through structured organization.
Solution Approach 2:
The patent implements a dual management approach where common information serves multiple component carriers simultaneously, reducing redundant transmissions. This multi-functionality improves efficiency by avoiding repeated communication of identical information across multiple carriers.
2Loss of time
If paging is used to update system information, then loss of time is reduced, but measurement precision decreases
Solution Approach 1:
The patent applies different update mechanisms to different types of information elements. Specific information elements use paging-based updates for speed, while common information elements use more precise RRC signaling. This local differentiation optimizes update time for carrier-specific information while maintaining accuracy for shared information.
Solution Approach 2:
The patent changes the update mechanism parameter based on the type of information element. By selecting different signaling methods (paging vs. RRC signaling) for different information types, the system optimizes the balance between update speed and precision for each category.
