Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional decoding methods are used for control information, then the system maintains simplicity in processing, but decoding accuracy deteriorates due to variations in transmission types and configurations
Solution Approach 1:
The system performs preliminary classification of transmission types and selects appropriate decoding configurations before actual decoding occurs. This advance preparation allows the system to handle various transmission types accurately without increasing real-time processing complexity, as the decision logic is pre-established through machine learning training
Solution Approach 2:
The system dynamically changes decoding parameters based on detected transmission type characteristics. By adjusting configuration parameters according to the specific transmission type identified, the system maintains high decoding accuracy across different transmission scenarios while using a unified processing framework
2Adaptability or versatility
If fixed processing rules are applied to all transmissions, then the system maintains operational simplicity, but adaptability to different transmission types deteriorates
Solution Approach 1:
The system segments the decoding process into distinct stages: transmission type detection, configuration selection, and decoding execution. This segmentation allows the system to adapt to different transmission types by selecting appropriate configurations for each segment while maintaining overall process simplicity through modular design
Solution Approach 2:
The system introduces an intermediary classification mechanism that detects transmission type characteristics and mediates between the input transmission and the decoding process. This intermediary layer enables adaptability to various transmission types without requiring the entire system to be complex, as only the classification and configuration selection components need adaptability
3Loss of time
If machine learning components are trained offline, then training time is reduced, but the ability to adapt to new transmission configurations deteriorates
Solution Approach 1:
The system performs comprehensive machine learning training offline in advance to establish baseline decoding capabilities. This preliminary action reduces online training time significantly while the system retains adaptability through configuration selection mechanisms that can handle new transmission types by matching them to learned patterns or selecting appropriate pre-configured decoding parameters

AI summary
A wireless transmit-receive unit (WTRU) may be configured to perform one or more actions. A first transmission of a first type and a second transmission of a second type may be received. The first transmission and the second transmission may be determined to be linked based on a time frequency relationship or configuration information. First control information may be determined based on the first transmission and pre-defined processing rules. The second transmission may be provided as an input to an artificial intelligence (Al) component and may cause the Al component to generate second control information as an output. A loss value may be determined based on a difference between the first control information and the second control information. The loss value may be used to train the Al component. The training of the Al component may be determined to satisfy a condition. An indication of the determination may be transmitted.
