Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user plane upper-layer data is transmitted through the complete protocol stack (SDAP, PDCP, RLC, MAC, PHY layers), then reliable data transmission is ensured, but the complexity of data transmission and power consumption increase significantly
Solution Approach 1:
The patent extracts and removes intermediate protocol layers (SDAP, PDCP, RLC, MAC) from the data transmission path, allowing user plane upper-layer data to be transmitted directly through the physical layer. This extraction principle eliminates unnecessary processing steps while maintaining transmission reliability through direct physical layer carrying of data.
Solution Approach 2:
Instead of following the conventional upward path through multiple protocol layers (SDAP→PDCP→RLC→MAC→PHY), the patent inverts the approach by transmitting data directly from the upper layer to the physical layer, bypassing the intermediate layers. This inversion fundamentally changes the transmission architecture to reduce complexity.
2Reliability
If the complete protocol stack (SDAP, PDCP, RLC, MAC layers) is used for data transmission, then comprehensive data handling and error control are achieved, but power consumption increases
Solution Approach 1:
The patent extracts and eliminates power-consuming intermediate protocol layers (SDAP, PDCP, RLC, MAC) from the transmission path. By removing these layers, the terminal device avoids the computational overhead and energy consumption associated with their processing functions, while still achieving reliable transmission through direct physical layer carrying.
Solution Approach 2:
The patent inverts the conventional energy-intensive multi-layer processing approach by transmitting data directly through the physical layer. This inversion eliminates the cumulative power consumption of multiple protocol layers while maintaining transmission reliability.
3Adaptability or versatility
If multiple protocol layers (SDAP, PDCP, RLC, MAC) are involved in data transmission, then comprehensive data processing and control functions are provided, but the communication procedure complexity increases
Solution Approach 1:
The patent extracts and removes intermediate protocol layers (SDAP, PDCP, RLC, MAC) that contribute to communication procedure complexity. By taking out these layers, the system maintains essential data processing capability through the physical layer while significantly reducing the complexity of communication procedures.
Solution Approach 2:
The patent inverts the conventional multi-layer processing architecture by transmitting data directly through the physical layer. This inversion simplifies communication procedures by eliminating the sequential processing steps through multiple protocol layers, while still providing necessary data handling capability.
