Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If bandwidth parts with multiple resource blocks are configured for downlink reception, then resource utilization efficiency is improved, but device complexity increases due to scheduling management

Engineering Contradiction:
Improveresource utilization efficiencyVSAvoidscheduling management complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent segments the downlink bandwidth into multiple bandwidth parts (BWPs), each containing multiple resource blocks (RBs). This segmentation allows independent configuration and scheduling of different RB groups, improving resource utilization efficiency while managing complexity through modular organization of radio resources.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If multiple bandwidth parts are configured to support diverse services, then service adaptability is improved, but system complexity increases

Engineering Contradiction:
Improveservice adaptabilityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a universal bandwidth part configuration framework where multiple BWPs can be defined with different parameters (subcarrier spacing, cyclic prefix length, frequency location) to support diverse services (eMBB, URLLC, mMTC). The same BWP configuration mechanism serves multiple service types, achieving service adaptability without proportionally increasing system complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)
