Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single allocation determination device is used for all terminal devices, then the device complexity is low, but it cannot simultaneously satisfy diverse requirements such as high-speed, large-capacity, and low-latency communications
Solution Approach 1:
The base station divides the allocation determination device into multiple independent units: a first allocation determination device for high-speed, large-capacity terminal devices and a second allocation determination device for low-latency terminal devices. Each unit is optimized for specific terminal device characteristics, enabling simultaneous satisfaction of diverse requirements while maintaining manageable complexity through functional separation.
2Reliability
If separate allocation determination devices are used for different terminal device groups, then the ability to meet diverse requirements is improved, but the device complexity increases
Solution Approach 1:
The base station implements segmented allocation determination with specialized devices for different terminal groups, improving reliability by optimizing each device for its specific function while managing complexity through clear division of responsibilities.
Solution Approach 2:
Each allocation determination device is designed to handle multiple aspects of resource allocation (time, frequency, spatial resources) within its specialized domain, providing multi-functional capability within segmented units rather than requiring a single complex universal device.
3Speed
If resource allocation is optimized for high-speed communications, then the data rate is improved, but the latency increases
Solution Approach 1:
The system segments the allocation determination function into two parallel paths: one optimized for high-speed data transmission with larger resource blocks and higher modulation schemes, and another optimized for low-latency communication with faster allocation timing. This segmentation allows simultaneous optimization of both speed and latency without compromise.
Solution Approach 2:
The base station dynamically selects which allocation determination device to use based on the terminal device's requirements and traffic characteristics, enabling adaptive optimization of speed versus latency trade-offs in real-time operational conditions.

The base station is capable of wirelessly communicating with terminal devices each having either a first characteristic or a second characteristic. The first allocation determination device determines allocation of communication resources to at least one of the terminal devices. The second allocation determination device determines allocation of communication resources to at least another one of the terminal devices.
