Engineering Contradiction Analysis
1Productivity
If 4G system technologies (OFDM, MIMO, HARQ) are used to improve frequency spectrum efficiency and system capacity, then cell capacity is improved, but the exponential increase in 5G communication data volume requirements cannot be satisfied
Solution Approach 1:
The patent changes the sampling rate parameter from conventional LTE values to ultra-large bandwidth values (e.g., 640 MHz, 1 GHz, or higher), enabling the system to handle 5G data volume requirements while maintaining LTE-compatible frame structures and processing architectures
2Productivity
If high frequency band resources are utilized to increase bandwidth, then data transmission capacity is improved, but transmission delay increases
Solution Approach 1:
The patent dynamically adjusts OFDM symbol configurations and sampling rates to optimize the balance between transmission capacity and delay, allowing the system to adapt to different service requirements (e.g., eMBB vs. uRLLC) while utilizing high frequency bands
3Productivity
If sampling rate is increased to achieve ultra-large bandwidth transmission, then throughput is improved, but implementation complexity increases
Solution Approach 1:
The patent designs a universal transmission framework that can operate at multiple sampling rates (from conventional LTE to ultra-large bandwidth), allowing the same hardware architecture to serve both legacy and advanced services through software-configurable parameters
4Loss of time
If real-time performance is optimized for low delay applications, then transmission delay is reduced, but data transmission capacity may be compromised
Solution Approach 1:
The patent segments the ultra-large bandwidth into multiple sub-carriers and OFDM symbols that can be independently configured for different service types, allowing simultaneous support for low-delay applications and high-capacity data transmission within the same frequency resource
