Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple antenna panels are used for simultaneous PUCCH transmissions, then throughput and reliability are improved, but system complexity and resource management difficulty increase
Solution Approach 1:
The patent divides the PUCCH transmission system into multiple independent antenna panels, each capable of simultaneous transmission. This segmentation allows parallel PUCCH transmissions across different panels, thereby increasing throughput while managing complexity through modular architecture
Solution Approach 2:
The patent introduces spatial dimension by utilizing multiple antenna panels in addition to time and frequency domains. This multi-dimensional approach enables simultaneous transmissions that overlap in time and frequency but are separated in space, resolving the contradiction between throughput improvement and system complexity
2Reliability
If multiple antenna panels are used for simultaneous PUCCH transmissions, then reliability is improved, but resource management complexity increases
Solution Approach 1:
The patent segments PUCCH resources into panel-specific configurations, allowing independent resource management for each antenna panel. This segmentation improves reliability through diverse transmission paths while simplifying resource management by treating each panel as an independent resource pool
Solution Approach 2:
The patent applies local quality by configuring different PUCCH resources specifically for each antenna panel based on local conditions. This allows optimized resource allocation for each panel while maintaining overall system reliability, reducing the complexity of global resource management
3Productivity
If PUCCH transmissions overlap in time and frequency domains, then spectral efficiency is improved, but interference management difficulty increases
Solution Approach 1:
The patent resolves time-frequency overlap by introducing the spatial dimension through multiple antenna panels. Transmissions can overlap in time and frequency domains to improve spectral efficiency, while spatial separation across panels minimizes interference, managing complexity through spatial domain processing
Solution Approach 2:
The patent uses spatial filtering and beamforming as intermediary mechanisms to manage interference between overlapping PUCCH transmissions on different antenna panels. These intermediaries enable spectral efficiency through overlap while controlling interference through spatial processing
