Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If carrier aggregation is implemented with fixed primary and secondary serving cell relationships, then network configuration is simplified, but carrier aggregation utilization is reduced due to misaligned cell boundaries

Engineering Contradiction:

Improvenetwork configuration complexityVSAvoidcarrier aggregation utilization

Core Design Contradiction:

Device complexityVSProductivity

Solution Approach 1:

The patent implements dynamic reconfiguration of primary and secondary serving cell relationships based on real-time UE location and network conditions. The base station monitors UE positions and adjusts cell relationships dynamically to maintain optimal carrier aggregation coverage, transforming the static cell configuration into an adaptive system that responds to changing conditions.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system employs feedback mechanisms where the base station continuously monitors carrier aggregation utilization statistics and UE location information. Based on this feedback, the base station determines when and how to reconfigure serving cell relationships, creating a closed-loop control system that optimizes carrier aggregation performance.

Inventive Principle:

Principle #23Feedback

2Adaptability or versatility

If serving carriers are configured to cover overlapping geographical areas, then carrier aggregation capability is enabled, but real-world installation constraints cause partial overlap and reduce aggregation activation

Engineering Contradiction:

Improvecarrier aggregation capabilityVSAvoidaggregation activation efficiency

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The base station performs preliminary assessment of UE location relative to serving cell coverage areas before attempting carrier aggregation activation. By predicting which UEs are likely to benefit from carrier aggregation based on their positions, the system proactively configures appropriate serving cell relationships in advance, rather than waiting for aggregation failures.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system changes the configuration parameters of serving cell relationships dynamically. When a UE moves into or out of optimal coverage areas, the base station adjusts parameters such as which cells serve as primary or secondary serving cells, thereby maintaining effective carrier aggregation coverage despite fixed physical cell boundaries.

Inventive Principle:

Principle #35Parameter changes

3Productivity

If dynamic reconfiguration of serving cell relationships is implemented, then carrier aggregation utilization is improved, but network control complexity increases

Engineering Contradiction:

Improvecarrier aggregation utilizationVSAvoidnetwork control complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The base station autonomously performs the reconfiguration of serving cell relationships without requiring manual intervention or complex coordination with other network elements. The system uses locally available information about UE positions and network conditions to make reconfiguration decisions, reducing the need for external control mechanisms.

Inventive Principle:

Principle #25Self-service

4Stability of the object's composition

If fixed serving cell relationships are maintained, then network stability is preserved, but geographic coverage gaps prevent UE from utilizing carrier aggregation benefits

Engineering Contradiction:

Solution Approach 1:

The patent introduces dynamic adjustment of serving cell relationships while maintaining overall network stability. The reconfiguration occurs transparently to UEs, with the base station managing changes in a way that preserves connection stability while expanding effective carrier aggregation coverage to previously unreachable geographic areas.

AI summary

Dynamic carrier aggregation cell relationship management systems and methods are provided. In some embodiments, carrier aggregation relationship configuration logic computes carrier aggregation utilization statistics for primary serving cell and secondary serving cell relationship configurations. The logic further reconfigures primary serving cell to secondary serving cell relationships based on the utilization statistics to provide carrier aggregation coverage to user equipment that most efficiently utilizes the extra bandwidth made available by activating a secondary serving cell for carrier aggregation. The ability to dynamically reconfigure primary service cell to secondary service cell relationships improves carrier aggregation utilization, reduces congestion, and improves network resource utilization.
