Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If reference signals are transmitted without feedback confirmation, then transmission speed is improved, but reliability deteriorates

Engineering Contradiction:
Improvetransmission speedVSAvoidreliability
Core Design Contradiction:
SpeedVSReliability

Solution Approach 1:

The patent implements a feedback mechanism where the receiving device sends acknowledgment information back to the transmitting device to confirm successful reception of control information. The transmitting device determines a feedback resource based on the control information and monitors this feedback resource for acknowledgment. This ensures reliable transmission by verifying receipt before proceeding with reference signal transmission, resolving the contradiction between speed and reliability.

Inventive Principle:
Principle #23Feedback

2Reliability

If feedback resources are allocated for every control information, then reliability is improved, but device complexity increases

Engineering Contradiction:
ImprovereliabilityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies local quality by differentiating feedback resource allocation based on the type of control information. For downlink control information, specific feedback resources are allocated, while for uplink control information, different feedback resources are used. The transmitting device determines the feedback resource type based on the specific control information being sent, allowing selective and efficient resource allocation that improves reliability without uniformly increasing complexity across all transmissions.

Inventive Principle:
Principle #3Local quality
