Solution Overview

Problem

Current wireless communication networks waste resources by allocating carrier aggregation bandwidth and bitrate uniformly at the initiation of communication, regardless of the specific data requirements of wireless devices, leading to inefficient use of resources.

Innovation Solution

Implementing a dynamic allocation method where eNodeB adjusts carrier aggregation configurations based on real-time requests from wireless communication devices, using quality of service indicators like QCI and APN to modify carrier aggregation from intra-band to inter-band or vice versa, depending on the bitrate needs of applications executing on the device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If carrier aggregation resources are allocated uniformly at communication initiation, then all devices receive sufficient bandwidth and bitrate, but resources are wasted when devices do not require increased bandwidth

Engineering Contradiction:
Improvequality of serviceVSAvoidresource waste
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The patent implements dynamic carrier aggregation configuration that adjusts resource allocation based on real-time device requests and application requirements. The system transitions from static uniform allocation to dynamic adaptive allocation, where the eNodeB modifies carrier aggregation parameters (such as number of component carriers, bandwidth per carrier) based on QoS indicators and device feedback, ensuring resources are allocated only when needed and at the appropriate level.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes key parameters of carrier aggregation configuration including the number of component carriers, aggregation bandwidth, and bitrate allocation based on device requests and application QoS requirements. The eNodeB receives QoS indicator messages from devices and adjusts carrier aggregation parameters accordingly, transforming the fixed parameter allocation into variable parameter allocation that matches actual demand.

Inventive Principle:
Principle #35Parameter changes

2Productivity

If carrier aggregation resources are allocated at communication initiation, then resource allocation is simple and fast, but resources cannot be adjusted to match changing data requirements

Engineering Contradiction:
Improveresource allocation efficiencyVSAvoidflexibility to data requirements
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent implements a feedback mechanism where wireless devices monitor their data requirements and send QoS indicator messages to the eNodeB requesting carrier aggregation configuration changes. The eNodeB processes these feedback messages and adjusts carrier aggregation parameters accordingly, creating a closed-loop control system that continuously adapts resource allocation to match changing application demands throughout the communication session.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system transforms static resource allocation into dynamic resource allocation by enabling real-time modification of carrier aggregation configurations based on device requests and application requirements, allowing the network to adapt flexibly to changing data needs while maintaining efficient resource utilization.

Inventive Principle:
Principle #15Dynamics

AI summary

Examples disclosed herein provide systems, methods, and software to dynamically provide carrier aggregation to wireless communication devices. In one example, a method of operating an eNodeB includes exchanging first wireless communication signals with a wireless communication device using a first carrier aggregation configuration. The method further provides identifying a request from the wireless communication device for a modified quality of service, and determining a second carrier aggregation configuration based on the request. The method also includes exchanging second wireless communication signals with the wireless communication device using the second carrier aggregation configuration.
