Solution Overview

Problem

Current carrier aggregation (CA) technologies activate all available radio resources in user equipment (UE) for data sessions, leading to inefficient use of spectrum and increased power consumption, despite many applications requiring fewer carriers for optimal performance.

Innovation Solution

A self-adaptive, intelligent CA system that dynamically configures a minimum number of component carriers based on application data requirements, reducing unnecessary activation of radio resources to optimize bandwidth utilization and power consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If all available radio resources are activated for carrier aggregation, then data throughput capability is maximized, but spectrum efficiency and power consumption deteriorate

Engineering Contradiction:
Improvedata throughput capabilityVSAvoidpower consumption
Core Design Contradiction:
ProductivityVSLoss of energy

Solution Approach 1:

The patent implements dynamic carrier activation where the network controller adjusts the number of activated component carriers based on real-time data buffer status and application requirements. Instead of statically activating all carriers, the system dynamically scales carrier activation to match actual data transmission needs, thereby reducing power consumption while maintaining throughput capability when required.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the operational parameters of carrier aggregation by adjusting the number of activated component carriers based on data buffer thresholds and application QoS requirements. This parameter adjustment allows the system to optimize between throughput and power consumption by activating only the necessary number of carriers for each transmission scenario.

Inventive Principle:
Principle #35Parameter changes

2Productivity

If maximum number of component carriers are configured, then data transmission capacity is improved, but spectrum efficiency deteriorates

Engineering Contradiction:
Improvedata transmission capacityVSAvoidspectrum utilization efficiency
Core Design Contradiction:
ProductivityVSQuantity of substance

Solution Approach 1:

The patent applies partial action by activating only the necessary number of component carriers required to clear the data buffer, rather than always using the maximum number of carriers. The system determines the optimal number of carriers based on data volume and application requirements, avoiding unnecessary spectrum occupation and improving overall spectrum efficiency.

Inventive Principle:
Principle #16Partial or excessive action

3Speed

If network activates maximum carriers based on data buffer size, then data transmission speed is improved, but resource allocation efficiency deteriorates

Engineering Contradiction:
Improvedata transmission speedVSAvoidresource allocation efficiency
Core Design Contradiction:
SpeedVSProductivity

Solution Approach 1:

The system implements feedback-based carrier activation where the network controller continuously monitors data buffer status, application QoS requirements, and current carrier activation state. Based on this feedback, the controller dynamically adjusts the number of activated carriers to match actual transmission needs, improving resource allocation efficiency while maintaining adequate transmission speed.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system enables self-service by allowing applications to indicate their QoS requirements and data urgency, which the network controller uses to automatically determine the appropriate number of carriers to activate. This self-service mechanism eliminates the need for manual resource allocation and improves overall system efficiency.

Inventive Principle:
Principle #25Self-service
