Carrier Aggregation Capability Reporting in LTE-A Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In current LTE-A systems, user equipment (UE) only operates in separate cells and does not inform the network of its carrier aggregation capability, preventing base stations from configuring carrier aggregation, which limits system performance and capacity.
Innovation Solution
A method and device where UE sends its carrier aggregation capability to the network, allowing the network to acquire and configure aggregated carriers based on the UE's capabilities, enabling efficient carrier aggregation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If UE only operates in separate cells and does not inform the network of its carrier aggregation capability, then the current LTE system structure is maintained, but the base station cannot configure carrier aggregation, limiting system performance and capacity
Solution Approach 1:
The UE performs preliminary action by sending its carrier aggregation capability information to the network side before the base station can configure carrier aggregation. This advance notification enables the network to prepare and configure appropriate carrier aggregation parameters, resolving the information loss problem and enabling improved system throughput.
2Productivity
If the network configures carrier aggregation for UE, then system throughput and capacity are improved, but the UE must first inform the network of its carrier aggregation capability
Solution Approach 1:
The patent extends the existing UE capability reporting mechanism to include carrier aggregation capability information. By making the capability reporting function universal and multi-functional, the system can handle both traditional capability reporting and the new carrier aggregation capability notification through the same established protocol framework, minimizing additional complexity.

AI summary
The present invention relates to a method and device for processing carrier aggregation capability, which method comprises: sending, by user equipment, its own carrier aggregation capability to the network side; acquiring, by network side equipment, the carrier aggregation capability of the user equipment; and configuring, by the network side equipment, aggregated carriers for the user equipment according to the carrier aggregation capability thereof. In the present invention, the sending of the carrier aggregation capability to the network side by the UE enables the network side to acquire the UE's carrier aggregation capability, thus ensuring the normal operation of the carrier aggregation system.
