Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If resources are allocated to different channels with different numerologies, modulation orders, and coding rates, then system capacity and service diversity are improved, but resource collisions and interference occur leading to inefficient resource utilization
Solution Approach 1:
The patent implements dynamic collision handling by adjusting resource block group sizes and allocation strategies based on detected collision conditions. The system dynamically modifies numerology parameters, modulation orders, and coding rates for different channels to resolve collisions, transforming a static resource allocation system into an adaptive one that responds to real-time interference conditions.
Solution Approach 2:
The patent changes key transmission parameters including numerology (subcarrier spacing, cyclic prefix length), modulation order (QPSK, 16QAM, 64QAM), and coding rates to resolve resource collisions. By adjusting these parameters dynamically based on collision detection, the system maintains service diversity while improving resource utilization efficiency.
2Reliability
If collision handling is initiated based on channel characteristics, then data transmission reliability is improved, but processing complexity increases
Solution Approach 1:
The patent segments collision handling into distinct processing stages: collision detection phase, analysis phase (examining numerology, modulation, coding characteristics), and resolution phase (applying appropriate handling strategies). This segmentation allows the system to manage complexity by processing only relevant channel characteristics when collisions are detected, rather than continuously analyzing all parameters.
Solution Approach 2:
The system performs self-diagnosis and self-correction by automatically detecting resource collisions and initiating appropriate collision handling procedures based on the detected channel characteristics. This self-service mechanism improves reliability without requiring external intervention, while the automated nature of the process limits the increase in processing complexity.
3Productivity
If resource block group sizes are dynamically adjusted, then resource allocation efficiency is improved, but control overhead and signaling complexity increase
Solution Approach 1:
The patent establishes universal rules for resource block group size adjustment that can be applied across different channel types (PDSCH, PUSCH, PUCCH) and different collision scenarios. By creating a multi-functional collision handling framework, the system improves resource allocation efficiency without proportionally increasing signaling complexity, as the same basic rules apply to multiple different situations.
