Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If terminal devices use physical uplink shared channels for information reporting, then information can be transmitted reliably, but power consumption increases
Solution Approach 1:
The patent extracts the information reporting function from the physical uplink shared channel and implements it through reference signals. By separating the reporting mechanism from traditional data channels, the system eliminates the need for complex data channel processing, thereby reducing terminal power consumption while maintaining reliable information transmission through the reference signal framework
Solution Approach 2:
The reference signals serve multiple functions: they carry positioning information, enable terminal identification, and support communication parameter reporting simultaneously. This multi-functionality eliminates the need for separate dedicated reporting channels, reducing overall system complexity and power consumption while ensuring reliable information delivery
2Adaptability or versatility
If terminal devices use data channels for information reporting, then comprehensive information can be transmitted, but device complexity increases
Solution Approach 1:
The patent extracts the information reporting function from the data channel processing framework and implements it through reference signals. This separation removes the complexity of data channel encoding, modulation, and resource allocation from the terminal, while maintaining comprehensive information reporting capability through the simplified reference signal mechanism
Solution Approach 2:
The system changes the fundamental parameter of information transmission from data channel-based to reference signal-based. This parameter change fundamentally simplifies the terminal architecture by eliminating complex data processing functions while maintaining versatile information reporting through the modified reference signal framework
