Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a radio device performs extensive channel monitoring and LBT procedures to determine idle channels, then the reliability of channel selection is improved, but the time consumption and complexity of the communication process increases
Solution Approach 1:
The patent applies preliminary action by having first devices perform channel sensing and report idle channel information to the sending device in advance. The sending device receives pre-collected signal information from multiple first devices, which have already performed LBT procedures. This allows the sending device to determine idle channels without performing extensive monitoring itself, thus reducing time consumption while maintaining reliability through aggregated sensing data from multiple sources.
2Measurement precision
If a sending device performs extensive channel monitoring to determine idle channels, then the measurement precision of channel availability is improved, but the device complexity and operational overhead increases
Solution Approach 1:
The patent applies segmentation by dividing the channel sensing task among multiple first devices rather than requiring a single sending device to perform all monitoring. Each first device independently performs LBT and reports results, segmenting the overall detection function. This reduces the complexity burden on any single device while maintaining or improving measurement precision through multiple independent assessments of channel availability.
Solution Approach 2:
The patent uses first devices as intermediaries between the physical channel and the sending device. These intermediary devices perform the complex LBT procedures and channel sensing, then relay the processed information to the sending device. This intermediary layer reduces the operational complexity of the sending device while maintaining accurate channel availability detection through the intermediaries' sensing capabilities.
3Adaptability or versatility
If multiple devices perform independent LBT procedures to find idle channels, then the adaptability of channel selection is improved, but the resource efficiency decreases due to redundant monitoring
Solution Approach 1:
The patent applies merging by combining the sensing efforts of multiple first devices into a unified set of idle channel recommendations for the sending device. Instead of each device independently performing redundant LBT procedures, the first devices share their sensing results and the sending device synthesizes this information to select idle channels. This merging approach maintains adaptability through multiple sensing perspectives while improving productivity by eliminating redundant monitoring activities.
