Engineering Contradiction Analysis
1Adaptability or versatility
If fixed basic communication parameters are used in existing wireless communication systems, then equipment implementation is simplified, but the system cannot support large-range changes in bandwidth, time delay, mobility, coverage, communication rate, reliability and number of users
Solution Approach 1:
The patent applies dynamics by enabling communication parameters (such as CP length, subcarrier spacing, resource block size) to be dynamically adjustable rather than fixed. The system can adapt these parameters in real-time based on network conditions, service requirements, and channel characteristics, allowing the same system to support diverse applications from low-mobility to high-mobility scenarios while maintaining manageable complexity through standardized adjustment mechanisms
Solution Approach 2:
The patent implements parameter changes by introducing a framework that allows fundamental communication parameters to be modified according to different service types and channel conditions. Specifically, the system can change cyclic prefix length, subcarrier spacing, and resource block granularity to optimize performance for different scenarios (e.g., extended CP for high delay spread, normal CP for low delay spread), thereby achieving versatile support without requiring completely different system configurations
2Reliability
If dynamic regulation of communication parameters is implemented, then system performance and applicability are improved, but system complexity increases
Solution Approach 1:
The patent applies feedback by establishing a closed-loop mechanism where the system continuously monitors channel conditions, service requirements, and communication performance, then adjusts communication parameters accordingly. The network device receives feedback about channel state and service type, processes this information, and dynamically regulates parameters such as CP length and subcarrier spacing to maintain optimal communication quality and reliability across varying conditions
Solution Approach 2:
The patent implements preliminary action by pre-defining a set of standardized parameter configurations and adjustment rules that can be applied based on recognized channel conditions and service types. Rather than requiring complex real-time calculations, the system uses pre-established parameter sets that are selected and applied based on feedback, reducing the computational complexity while maintaining the ability to adapt to different scenarios
