Solution Overview

Problem

In wireless communication systems, especially in the context of 6G, dynamic frequency sharing between mobile network operators leads to resource collisions, resulting in inefficient use of frequency resources due to the inability to fully utilize allocated spectrum, especially during periods of low data traffic.

Innovation Solution

A method and apparatus where a second base station communicates with a first base station to determine and control the usage of shared frequency resources, allowing for dynamic adjustment and optimization of resource allocation to prevent collisions, thereby enabling more efficient use of frequency resources across different mobile network operators.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If dynamic frequency sharing is implemented between mobile network operators, then frequency resource utilization is improved, but resource collisions occur resulting in inefficient use of frequency resources

Engineering Contradiction:
Improvefrequency resource utilizationVSAvoidresource collision
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent applies preliminary action by having base stations transmit usage information about shared frequency resources before actual data transmission occurs. The first base station transmits usage information indicating its intended use of the shared resource, allowing the second base station to determine collision status in advance and make scheduling decisions beforehand, preventing collisions before they happen.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback through the exchange of usage information between base stations. The first base station transmits usage information to the second base station, which then determines whether a collision has occurred and can respond with collision status information. This feedback loop enables dynamic adjustment of resource allocation based on actual usage patterns.

Inventive Principle:
Principle #23Feedback

2Reliability

If exclusive spectrum allocation is maintained, then resource collision is avoided, but frequency resource utilization efficiency deteriorates during low data traffic periods

Engineering Contradiction:
Improveresource collision avoidanceVSAvoidfrequency resource utilization efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent applies dynamics by transitioning from static exclusive allocation to dynamic shared allocation. Base stations can dynamically access shared frequency resources based on real-time traffic conditions and usage information exchange. The system dynamically adjusts who uses the resource and when, allowing efficient utilization during low traffic periods while maintaining collision avoidance through the information exchange mechanism.

Inventive Principle:
Principle #15Dynamics

3Productivity

If base stations transmit usage information to determine collision status, then resource allocation optimization is improved, but communication overhead increases

Engineering Contradiction:
Improveresource allocation optimizationVSAvoidcommunication overhead
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent applies local quality by having each base station transmit only the specific usage information relevant to the shared resource it intends to use. The information is localized to the specific frequency resource and time slot, rather than requiring comprehensive system-wide status broadcasts. This targeted approach reduces overall communication overhead while maintaining effective collision detection.

Inventive Principle:
Principle #3Local quality
