Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If terminal devices perform sidelink communication without effective abnormality handling mechanisms, then communication simplicity is maintained, but communication reliability deteriorates due to potential communication failures
Solution Approach 1:
The patent implements preliminary action by establishing timers (e.g., first timer for monitoring response messages, second timer for monitoring physical sidelink feedback channels) and detection mechanisms before communication failures occur. These timers are started in advance to monitor for abnormal conditions, allowing the system to detect and respond to sidelink abnormalities proactively rather than reactively, thereby improving communication reliability without requiring complex real-time intervention mechanisms.
Solution Approach 2:
The patent employs feedback mechanisms where terminal devices monitor for response messages from counterpart devices and use this feedback to determine whether abnormalities have occurred on sidelinks. The system continuously receives feedback through monitoring procedures (e.g., checking for presence of response messages within timer intervals) and adjusts its behavior based on this feedback, such as suspending or releasing bearers when abnormalities are detected. This feedback-driven approach enables reliable abnormality handling while maintaining relatively simple device complexity.
2Reliability
If terminal devices implement comprehensive abnormality detection and response mechanisms, then data transmission reliability improves, but system complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the abnormality handling mechanism into distinct functional components: detection phase (monitoring for response messages using timers), determination phase (comparing received messages against expected responses to identify abnormalities), and response phase (suspending, releasing, or reestablishing bearers based on abnormality determination). This segmentation allows each component to perform its specific function independently, improving data transmission reliability through comprehensive monitoring while keeping overall system complexity manageable through modular design.
Solution Approach 2:
The patent implements dynamics by making the system's response behavior adaptive based on detected conditions. When abnormalities are detected on sidelinks, the system dynamically adjusts its operation by suspending or releasing specific bearers or entities rather than maintaining fixed behavior. This dynamic response allows the system to maintain high reliability by adapting to changing communication conditions while avoiding the complexity of pre-configuring multiple static handling strategies.
3Measurement precision
If terminal devices use timer-based monitoring mechanisms for sidelink abnormalities, then detection accuracy improves, but time consumption increases
Solution Approach 1:
The patent employs periodic action through timer-based monitoring mechanisms where terminal devices periodically check for response messages at predetermined intervals (e.g., starting a first timer when transmitting a message and checking for response before it expires, or periodically monitoring physical sidelink feedback channels). This periodic monitoring approach improves abnormality detection accuracy by systematically checking for abnormalities at regular intervals rather than continuously, thereby achieving reliable detection while minimizing time consumption through efficient use of discrete monitoring moments rather than continuous monitoring.
