Semantic Data Transmission with Feedback-Driven Redundancy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing number of communication devices and data throughput in wireless communication systems poses a challenge in efficiently managing limited radio resources, particularly in terms of latency, reliability, and supporting diverse services.
Innovation Solution
A method for transmitting semantic data in a wireless communication system involves sending a first semantic message, receiving feedback, and then transmitting a second semantic message with redundancy data if the feedback does not match the intended result, thereby ensuring accurate data interpretation and recovery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If semantic data is transmitted without redundancy, then data throughput is improved, but reliability deteriorates when feedback does not match intended results
Solution Approach 1:
The patent applies partial redundancy by transmitting redundancy data only when feedback indicates semantic communication failure. Instead of always transmitting full redundant information, the system transmits only the necessary portion (semantic message or redundancy data) based on feedback conditions, thus improving throughput while maintaining reliability when needed.
Solution Approach 2:
The patent changes the transmission parameter dynamically based on feedback results. When feedback matches the intended result, only semantic messages are transmitted (high throughput). When feedback does not match, redundancy data is transmitted (high reliability). This parameter change resolves the contradiction by adapting transmission mode to actual communication needs.
2Reliability
If redundancy data is always transmitted, then reliability is improved, but data throughput deteriorates due to increased transmission volume
Solution Approach 1:
The patent uses partial redundancy by transmitting only semantic messages when feedback indicates successful communication, and only transmitting redundancy data when feedback indicates failure. This partial approach to redundancy maintains reliability when necessary while avoiding unnecessary transmissions that would reduce throughput.
Solution Approach 2:
The patent implements a feedback mechanism where the receiving device sends feedback about whether the semantic message was correctly interpreted. This feedback controls whether redundancy data is transmitted, ensuring reliability only when actually needed rather than always transmitting redundancy, thus maintaining high throughput.
3Reliability
If semantic messages are retransmitted when feedback does not match, then reliability is improved, but latency increases due to additional transmission rounds
Solution Approach 1:
The patent prepares redundancy data in advance alongside the semantic message. When feedback indicates communication failure, the pre-prepared redundancy data can be transmitted immediately without needing to generate or retrieve it, reducing the time penalty for retransmission and thus reducing latency while maintaining reliability.
4Reliability
If feedback mechanisms are implemented, then reliability is improved through error detection, but device complexity increases due to additional processing requirements
Solution Approach 1:
The patent implements a feedback mechanism where the receiving device compares the interpreted semantic result with the intended result and sends feedback to the transmitting device. This feedback loop enables error detection and triggers appropriate retransmission actions, improving reliability through relatively simple comparison and feedback transmission logic.

AI summary
In a wireless communication system, a transmission device may transmit semantic data. The transmission device may: transmit a first semantic message including the semantic data to a reception device; receive a first semantic feedback for the first semantic message from the reception device; and on the basis that a result included in the semantic feedback does not agree with the result intended by the transmission device through the first semantic message, transmit a second semantic message including first redundancy data related to the semantic data to the reception device.
