Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a transmitting UE uses CBR indications from multiple receiving UEs to calculate a combined CBR, then the accuracy of channel busy condition representation is improved, but the device complexity increases due to additional processing and coordination requirements
Solution Approach 1:
The patent combines CBR indications from multiple receiving UEs into a single combined CBR value that represents the overall channel busy condition. This merging approach improves measurement precision by aggregating information from multiple sources while managing complexity through standardized combining procedures defined in the communication protocol.
Solution Approach 2:
The combined CBR mechanism serves multiple functions: it provides accurate channel status representation, enables resource utilization optimization, and facilitates congestion control. By making the CBR combining process universally applicable across different UE configurations, the system achieves improved measurement precision without proportionally increasing complexity.
2Productivity
If the transmitting UE adjusts resource utilization based on the combined CBR, then resource allocation efficiency is improved, but the loss of time increases due to additional processing delays
Solution Approach 1:
The system performs preliminary CBR combining and resource utilization adjustment actions before actual data transmission occurs. By preparing resource allocation decisions in advance based on the combined CBR, the system improves resource allocation efficiency while minimizing real-time processing delays during the actual communication.
Solution Approach 2:
The combined CBR mechanism establishes a feedback loop where receiving UEs report their channel conditions, the transmitting UE combines this information, and adjusts resource utilization accordingly. This feedback-driven approach enables continuous optimization of resource allocation efficiency with controlled processing time through periodic updates rather than continuous monitoring.
