Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple control information messages indicate different time and frequency resources, then the system provides more resource options for transmission, but the complexity of determining the appropriate PUCCH resource increases
Solution Approach 1:
The patent applies parameter changes by utilizing multiple parameters (transport block, coreset, PDCCH monitoring occasion, search space set, timing, and priority parameter) to determine the PUCCH resource. By changing and comparing these parameters across multiple control information messages, the system resolves resource allocation conflicts and determines the appropriate resource without requiring complex manual intervention.
Solution Approach 2:
The patent segments the resource determination process into distinct evaluation steps based on different parameters. Each parameter (transport block, coreset, monitoring occasion, etc.) is evaluated separately to determine resource priority and selection, breaking down the complex decision-making into manageable segments that can be processed systematically.
2Productivity
If multiple control information messages are received in the same monitoring period, then the system can schedule more transmissions, but the difficulty of detecting and measuring the appropriate resource increases
Solution Approach 1:
The system uses parameter changes to differentiate between multiple control information messages received in the same monitoring period. By evaluating variations in parameters such as transport block size, coreset index, monitoring occasion timing, and priority parameters, the system can detect and measure the appropriate PUCCH resource even when multiple messages are present, reducing the difficulty of resource detection.
Solution Approach 2:
The patent employs feedback mechanisms where the determined PUCCH resource parameters are used to confirm appropriate resource selection. The system evaluates whether the selected resource meets all criteria based on the received control information messages and adjusts the selection if necessary, providing a feedback loop that simplifies the detection and measurement process.
3Measurement precision
If the system uses multiple parameters to determine PUCCH resource, then the accuracy of resource selection improves, but the device complexity increases
Solution Approach 1:
The patent leverages parameter changes to improve resource selection accuracy. By monitoring and comparing multiple parameters (transport block, coreset, PDCCH monitoring occasion, search space set, timing, and priority parameter) across different control information messages, the system achieves precise resource selection. The parameters are evaluated in a systematic manner that improves accuracy while managing complexity through structured comparison.
Solution Approach 2:
The determination process is segmented into distinct evaluation stages, each focusing on specific parameters. This segmentation allows the system to evaluate parameters in a structured sequence, improving measurement precision by considering multiple factors while reducing overall complexity by breaking down the evaluation into manageable segments rather than processing all parameters simultaneously.
Data Source
AI summary
Wireless resource determination and use are described. A wireless device may determine to use a resource (e.g., PUCCH resource), indicated by control information (e.g., DCI), for sending an acknowledgement (e.g., HARQ-ACK feedback) of a reception of data (e.g., at least one transport block). The control information may be received in a message of a plurality of messages. The wireless device may select the control information (e.g., for determining the resource) from among other control information in the plurality of messages, based on one or more factors.
