Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If terminal-dedicated resources are allocated to reduce latency, then latency control is improved, but resource allocation complexity increases

Engineering Contradiction:
ImprovelatencyVSAvoidresource allocation complexity
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The base station performs preliminary actions by determining terminal-dedicated resources in advance based on predicted packet arrival times and communication patterns. The control section pre-calculates optimal resource allocation before actual data transmission occurs, allowing the terminal to use these pre-allocated resources for low-latency communication without real-time complex decision-making.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements feedback mechanisms where the terminal reports its communication needs and packet arrival predictions to the base station. The base station uses this feedback information to adjust and optimize terminal-dedicated resource allocation dynamically, balancing latency reduction with appropriate resource management complexity.

Inventive Principle:
Principle #23Feedback

2Productivity

If terminal-dedicated resources are used for low latency communication, then communication efficiency is improved, but system overhead increases

Engineering Contradiction:
Improvecommunication efficiencyVSAvoidsystem overhead
Core Design Contradiction:
ProductivityVSQuantity of substance

Solution Approach 1:

The patent applies local quality by providing terminal-dedicated resources with specialized characteristics optimized for low-latency communication. These resources have different properties compared to shared resources, including dedicated time slots, priority levels, and customized allocation parameters that match the specific needs of each terminal, thereby improving communication efficiency for critical data transmissions.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system implements partial action by allocating terminal-dedicated resources only when and where needed, rather than continuously reserving resources for all terminals. The control section determines based on actual communication patterns and packet arrival predictions, allocating resources partially to reduce overall system overhead while maintaining efficiency for active communications.

Inventive Principle:
Principle #16Partial or excessive action
