Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If reference signals are transmitted without feedback confirmation, then transmission speed is improved, but reliability deteriorates
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.
2Reliability
If feedback resources are allocated for every control information, then reliability is improved, but device complexity increases
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.
