Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate channel coding units are used for each radio access technology, then each RAT can be independently optimized, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent implements a universal channel coding unit that can perform channel coding functions for multiple different radio access technologies (GSM, WCDMA, LTE, etc.) through software configuration rather than requiring separate hardware units for each RAT. This multi-functional approach allows a single physical unit to serve multiple purposes across different communication standards, thereby reducing device complexity while maintaining RAT-specific optimization capabilities through configurable software algorithms.
2Adaptability or versatility
If multiple separate channel coding units are provided for different radio access technologies, then each technology can be independently managed, but the manufacturing cost and device complexity increase
Solution Approach 1:
The channel coding unit is designed as a universal platform that can be configured to support multiple radio access technologies through software rather than requiring separate hardware implementations for each RAT. This approach significantly reduces manufacturing costs by eliminating the need to produce and stock multiple types of channel coding units, while maintaining the ability to adapt to different RAT requirements through software configuration.
Solution Approach 2:
The patent merges the channel coding functions for multiple different radio access technologies into a single integrated unit. Instead of having separate GSM channel coding, WCDMA channel coding, and LTE channel coding units, the invention combines these functions into one unified unit that can dynamically switch between or simultaneously handle different RATs, thereby reducing component count and manufacturing complexity.
3Ease of operation
If channel coding is handled separately for each radio access technology, then processing is straightforward, but resource utilization efficiency decreases
Solution Approach 1:
The universal channel coding unit maintains processing simplicity through a unified architecture that handles multiple RATs through a single processing path, while improving resource utilization by enabling dynamic allocation of coding resources. The unit can efficiently switch between different coding schemes (GSM's convolutional coding, WCDMA's turbo coding, LTE's turbo/LDPC coding) without requiring separate processing chains, thereby optimizing resource usage while keeping operations straightforward.
