Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If frequent SR/PUSCH transmission is performed to ensure data transmission reliability, then communication reliability is improved, but power consumption increases rapidly
Solution Approach 1:
The patent applies dynamics by making the SR transmission configuration adaptable and adjustable. The network can dynamically configure the sr-TransMax parameter to adjust the maximum number of SR transmissions based on actual network conditions and device power status, transforming a static transmission scheme into a dynamic one that balances reliability and power consumption
Solution Approach 2:
The patent changes the transmission parameter sr-TransMax from a fixed value to a configurable parameter. By modifying this parameter, the system can control the number of SR transmission attempts, thereby adjusting the balance between ensuring communication reliability and reducing power consumption based on different operational scenarios
2Use of energy by moving object
If SR transmission number is reduced to save power, then power consumption is optimized, but communication reliability may deteriorate
Solution Approach 1:
The patent implements feedback mechanisms where the network monitors SR transmission outcomes and adjusts the sr-TransMax parameter accordingly. When SR transmissions succeed within the configured limit, the system maintains reliability while saving power. When transmission limits are approached or failed, the network can reconfigure parameters to ensure reliability is maintained
Solution Approach 2:
The patent applies preliminary action by pre-configuring the sr-TransMax parameter before actual data transmission occurs. This allows the system to establish appropriate transmission limits in advance based on predicted traffic patterns and power constraints, preventing both excessive power consumption and reliability issues during actual operation
