Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single frame format is used in the communication system, then the system configuration is simple and easy to manage, but the communication performance and efficiency are limited for diverse service requirements

Engineering Contradiction:
Improveadaptability to different service requirementsVSAvoidsystem configuration complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the communication system into multiple frame formats (first frame format and second frame format) with different radio parameters, allowing each format to be optimized for specific service types (e.g., eMBB, eMTC, URLLC). This segmentation enables the system to handle diverse service requirements independently while maintaining overall system organization through separate configuration and management of each frame format type.

Inventive Principle:
Principle #1Segmentation

2Productivity

If multiple frame formats with different radio parameters are used to satisfy various service requirements, then the communication performance and efficiency are improved, but the complexity of power control and resource management increases

Engineering Contradiction:
Improvecommunication efficiencyVSAvoidpower control complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent applies local quality by configuring transmit power control parameters specifically for each frame format type. The base station sets different target received powers, propagation loss compensation coefficients, and maximum transmit power limits according to the characteristics of each frame format (first or second format). This allows optimized power control for each service type while maintaining systematic management through format-specific configuration tables and signaling.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent changes key power control parameters (target received power Po, propagation loss compensation coefficient α, maximum transmit power PCMAX) based on the frame format type. The base station configures different parameter sets for first frame format and second frame format, and dynamically adjusts these parameters according to service requirements, channel conditions, and resource allocation, enabling flexible optimization of communication efficiency for different services.

Inventive Principle:
Principle #35Parameter changes

3Productivity

If transmit power control is performed without considering frame structure differences, then the control process is simple, but the communication performance and throughput are suboptimal

Engineering Contradiction:

Solution Approach 1:

The patent implements preliminary action by pre-configuring transmit power control parameters for each frame format type before actual communication. The base station establishes target received powers, propagation loss compensation coefficients, and power limits for both first and second frame formats in advance, storing these configurations for rapid retrieval and application. This preliminary setup enables optimized throughput performance without adding complex real-time decision-making during power control execution.
