Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If carrier aggregation is implemented to support larger bandwidths, then spectral efficiency and data rates are improved, but the system cannot adapt to variations in user traffic and device locations, leading to reduced data speeds for individual user equipment devices

Engineering Contradiction:

Improvespectral efficiencyVSAvoidadaptability to user traffic variations

Core Design Contradiction:

ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic carrier aggregation scheme selection where the base station continuously monitors user equipment location and traffic characteristics, then adapts the carrier aggregation configuration in real-time. This transforms the static carrier aggregation approach into a dynamic system that adjusts component carrier allocation based on current network conditions, user location, and traffic demands, thereby resolving the contradiction between maintaining high spectral efficiency and adapting to varying user requirements

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes key parameters including the number of component carriers allocated to each user equipment device, the bandwidth of assigned carriers, and the aggregation scheme type (e.g., contiguous vs. non-contiguous aggregation). By dynamically adjusting these parameters based on user location and traffic characteristics, the system optimizes spectral efficiency for each user while adapting to varying conditions, thus resolving the contradiction between high spectral efficiency and adaptability

Inventive Principle:

Principle #35Parameter changes

2Speed

If carrier aggregation is implemented to support larger bandwidths, then data rates are improved, but individual user equipment devices experience reduced data speeds due to inability to address user traffic variations

Engineering Contradiction:

Improvedata ratesVSAvoiddata speed consistency

Core Design Contradiction:

SpeedVSReliability

Solution Approach 1:

The patent applies local quality by assigning different carrier aggregation configurations to different user equipment devices based on their specific location and traffic characteristics. Each user receives a customized aggregation scheme tailored to their local conditions rather than a uniform allocation, ensuring that data speed requirements are met for each individual user while maintaining high overall spectral efficiency across the network

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The system dynamically adjusts the carrier aggregation configuration for each user equipment device in real-time based on changing traffic conditions and location. This dynamic adaptation ensures that data speeds remain consistent and reliable for each user by continuously optimizing the resource allocation, preventing the degradation of data speed reliability that occurs with static allocation approaches

Inventive Principle:

Principle #15Dynamics

3Productivity

If carrier aggregation is implemented to support bandwidths larger than 20 MHz, then IMT-Advanced requirements are met, but it is difficult to provide satisfying service to all user equipment devices

Engineering Contradiction:

Improvebandwidth capacityVSAvoidservice satisfaction for all users

Core Design Contradiction:

ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent segments the total available bandwidth into multiple component carriers that can be selectively allocated to different user equipment devices. Instead of allocating the entire aggregated bandwidth to a single user, the system divides and distributes component carriers among multiple users based on their individual requirements, location, and traffic characteristics. This segmentation enables the system to meet IMT-Advanced bandwidth requirements while providing satisfactory service to all users through fair and efficient resource distribution

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system dynamically changes allocation parameters including the number of component carriers assigned to each user, the bandwidth of assigned carriers, and the aggregation scheme type. By adjusting these parameters based on user location and traffic characteristics, the system simultaneously achieves high overall bandwidth utilization (meeting IMT-Advanced requirements) and individual user satisfaction through customized allocation for each device
