Solution Overview

Problem

In carrier aggregation communication networks, existing technologies face challenges in efficiently selecting and updating component carriers to ensure optimal quality of service and bandwidth utilization, especially with varying terminal, base station, and network conditions.

Innovation Solution

A method and device for selecting and updating component carriers in a carrier aggregating communication network, which involves determining the coverage range of available carriers, assessing the distribution mode of these ranges, and selecting or updating carriers based on predetermined rules and conditions to ensure optimal performance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If carrier aggregation is implemented to support wider transmission bandwidth, then the transmission bandwidth capacity is improved, but the device complexity and carrier management difficulty increase

Engineering Contradiction:
Improvetransmission bandwidthVSAvoidcarrier management complexity
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The patent segments carrier management into two distinct parts: primary component carrier (PCC) management handled by the network side for centralized control, and secondary component carrier (SCC) management handled by the terminal side for autonomous operation. This segmentation reduces overall management complexity while maintaining wide bandwidth capability through carrier aggregation.

Inventive Principle:
Principle #1Segmentation

2Reliability

If multiple carriers are aggregated to meet increasing quality of service requirements, then the quality of service is improved, but the radio resource management complexity increases

Engineering Contradiction:
Improvequality of serviceVSAvoidradio resource management complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent divides radio resource management responsibilities: the network side manages PCC selection, addition, modification, and deletion to ensure QoS requirements are met, while the terminal autonomously manages SCC operations. This segmentation simplifies radio resource management while maintaining the ability to aggregate multiple carriers for high QoS.

Inventive Principle:
Principle #1Segmentation

3Productivity

If centralized carrier management is implemented with primary component carrier concept, then the carrier management efficiency is improved, but the terminal autonomy and flexibility are reduced

Engineering Contradiction:
Improvecarrier management efficiencyVSAvoidterminal autonomy
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent segments carrier management authority: centralized control over PCC for efficient network-side management, and autonomous control over SCC for terminal-side flexibility. This dual-mode approach maintains both carrier management efficiency through centralized PCC control and terminal autonomy through independent SCC management.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements dynamic carrier management where the terminal can autonomously add or delete SCCs based on real-time service requirements and network conditions, while the PCC remains under centralized control. This dynamic approach balances centralized management efficiency with terminal adaptability.

Inventive Principle:
Principle #15Dynamics

AI summary

A method, base station, terminal and communication system for updating component carriers are provided. Wherein, status information of the terminal, base station and/or component carrier is acquired; whether the status information accords with the predetermined condition is determined; an old component carrier is replaced by a new component carrier, or a new component carrier is added in the even that the predetermined condition is met. With the embodiments of the present invention, the component carrier which the terminal would use is updated more effectively.
