Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If different processing capabilities are configured for each serving cell, then service delivery can be optimized for specific cell characteristics, but system complexity increases due to unequal processing times across cells
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting processing time parameters for different serving cells based on their specific characteristics. Each cell can have customized processing time configurations that match its traffic load, channel conditions, and service requirements, thereby optimizing service delivery without requiring complete system redesign
Solution Approach 2:
The invention implements dynamics by enabling flexible and dynamic processing time allocation across different serving cells. The system can adapt processing capabilities in real-time according to varying network conditions, allowing cells to transition between different processing modes based on instantaneous requirements
2Device complexity
If processing times are equalized across all serving cells, then system complexity is reduced and scheduling becomes simpler, but service optimization for specific cell characteristics is lost
Solution Approach 1:
The patent applies segmentation by dividing the network into multiple serving cells, each capable of independent processing time configuration. This allows the system to manage complexity at the cell level while maintaining overall coordination, enabling simplified scheduling within each cell while preserving optimization capabilities across the network
Solution Approach 2:
The invention implements universality by creating a multi-functional processing framework that can operate in different modes. The system can switch between equalized processing time mode for simplicity and differentiated processing time mode for optimization, making it adaptable to various operational scenarios and service requirements
3Adaptability or versatility
If multiple services with varying characteristics are transmitted simultaneously, then service diversity and user satisfaction improve, but resource allocation complexity and interference management difficulty increase
Solution Approach 1:
The patent applies local quality by allowing different resource allocation strategies and processing parameters to be applied to different serving cells based on their local characteristics. Each cell can optimize its resource allocation for the specific mix of services it handles, reducing overall system complexity while maintaining service diversity
Solution Approach 2:
The invention implements dynamics by enabling dynamic resource allocation that adapts to changing service requirements in real-time. The system can adjust processing times, resource blocks, and interference management parameters dynamically based on the current service mix and network conditions

AI summary
A method performed by a terminal in a wireless communication system comprises receiving a physical downlink shared channel (PDSCH) or a physical downlink control channel (PDCCH) from a first serving cell among a plurality of serving cells configured for the terminal, the plurality of serving cells including the first serving cell and a second serving cell for transmitting a physical uplink control channel (PUCCH) or a physical uplink shared channel (PUSCH), in case that different processing capabilities are configured for each of the plurality of serving cells, determining a time interval related to a timing at which the PUCCH or the PUSCH is transmitted in the second serving cell, from a last timing at which the PDSCH or the PDCCH is received in the first serving cell, and transmitting the PUCCH or the PUSCH to a base station, based on the determined time interval.
