Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In wireless communication networks, the sharing of components among multiple component carriers (CCs) leads to interference and reduced throughput when switching between CCs, as adjusting components for one CC can negatively impact other CCs using the same component path.

Innovation Solution

A method and apparatus for identifying CCs that share a component path, determining whether to switch one or more CCs, and adjusting the components accordingly to minimize interference and maintain throughput, including delaying or rerouting transmissions until the component path returns to its default state.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If multiple CCs share the same component path to reduce device complexity, then device complexity is reduced, but interference occurs and throughput decreases when switching between CCs

Engineering Contradiction:

Improvecomponent sharingVSAvoidthroughput

Core Design Contradiction:

Device complexityVSProductivity

Solution Approach 1:

The patent implements dynamic carrier switching by monitoring interference levels and throughput metrics for each CC, then dynamically selecting which CC to switch to based on current network conditions. This allows the system to adaptively manage shared components, switching between CCs as needed to maintain throughput while utilizing component sharing to reduce complexity.

Inventive Principle:

Principle #15Dynamics

2Reliability

If components are adjusted for one CC to improve its performance, then performance of that CC is improved, but other CCs using the same component path are negatively impacted

Engineering Contradiction:

ImproveCC performanceVSAvoidinterference to other CCs

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies preliminary anti-action by proactively identifying potential interference issues before they occur. The system monitors component path usage and predicts when switching to a shared CC might cause interference to other CCs, then prevents such switching or adjusts the switching strategy in advance to avoid the harmful effect.

Inventive Principle:

Principle #9Preliminary anti-action

Solution Approach 2:

The system continuously monitors performance metrics and interference levels across all CCs, using this feedback to dynamically adjust carrier switching decisions. When interference is detected or predicted, the feedback mechanism triggers a reevaluation of switching strategies to prevent further degradation of other CCs while maintaining overall system performance.

AI summary

Component carriers (CC)s that share components of a component chain are effected when components of the component chain are adjusted for one or more of the CCs. Systems switch CCs that share a component chain according to methods that alleviate drawbacks associated with sharing a component chain. In embodiments, CCs that share a component chain are identified as switching groups and are switched from default CCs to alternative CCs as a group to compensate for adjustments made in the shared component chain. Other aspects and features are also claimed and described.
