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 device complexity increases
Solution Approach 1:
The UE divides the antenna system into multiple independent antenna panels, each capable of simultaneous PUCCH transmission. This segmentation allows parallel transmission paths while maintaining manageable complexity through modular architecture, directly resolving the contradiction between improved throughput and device complexity
Solution Approach 2:
The patent introduces spatial dimension by utilizing multiple antenna panels in different spatial locations for simultaneous transmissions. This dimensional expansion enables parallel PUCCH transmissions without proportionally increasing processing complexity, as each panel operates semi-independently in its own spatial domain
2Reliability
If multiple antenna panels are used for simultaneous PUCCH transmissions, then reliability is improved, but device complexity increases
Solution Approach 1:
By segmenting the transmission function across multiple antenna panels, the system achieves reliability through spatial diversity while keeping each panel's complexity manageable. The segmentation allows independent operation of each panel, improving overall reliability without linearly increasing total device complexity
Solution Approach 2:
The patent changes the spatial parameter by utilizing multiple antenna panels with different spatial configurations. This parameter change enables simultaneous transmissions with inherent spatial diversity, improving reliability while the standardized panel architecture prevents exponential complexity growth
3Productivity
If PUCCH transmissions overlap in time domain, then resource utilization is improved, but interference increases
Solution Approach 1:
The patent resolves the interference issue by moving transmissions to different spatial dimensions through multiple antenna panels. PUCCH transmissions can overlap in time and frequency domains but are separated in spatial domains, achieving high resource utilization while minimizing interference through spatial isolation
Solution Approach 2:
The multiple antenna panels act as intermediaries that enable simultaneous transmissions. Each panel serves as an independent transmission path, allowing time-domain overlapping PUCCH transmissions to coexist with reduced mutual interference, effectively mediating between resource utilization and interference constraints
