Engineering Contradiction Analysis
1Reliability
If communication systems use predefined specific situations (airplane takeoff/landing, subway station, airport, elevator) for optimization, then communication performance is improved for those specific scenarios, but the system cannot adapt to user-specific or ordinary communication environments, leading to suboptimal performance in diverse settings
Solution Approach 1:
The system dynamically adapts communication parameters based on the recognized main communication environment. The UE identifies whether the current environment matches predefined main communication environments (such as indoor, outdoor, moving vehicle) and adjusts communication parameters in real-time accordingly, transforming the system from static predefined optimization to dynamic environment-adaptive optimization.
Solution Approach 2:
The system changes communication parameters (such as transmission power, modulation scheme, coding rate) based on the recognized main communication environment. By adjusting these parameters according to the identified environment type, the system achieves optimal communication performance for diverse settings beyond specific predefined scenarios.
2Use of energy by moving object
If the system optimizes for specific predefined situations, then power consumption is reduced for those scenarios, but power efficiency deteriorates in user-designated or frequently encountered environments
Solution Approach 1:
The system dynamically adjusts power consumption based on the recognized main communication environment. By identifying the current environment type and adapting communication parameters accordingly, the system achieves power efficiency in user-specific and frequently encountered environments, not just in predefined scenarios.
Solution Approach 2:
The UE autonomously identifies its main communication environment and self-adjusts communication parameters without requiring manual configuration or extensive user input. The system serves itself by automatically adapting to the environment where the UE is mainly exposed, achieving power efficiency through self-driven environment recognition and parameter optimization.
3Reliability
If the UE continuously monitors and adapts to communication environment, then communication performance is optimized for the current environment, but device complexity and processing overhead increase
Solution Approach 1:
The system performs preliminary actions by pre-defining main communication environments and their associated optimal communication parameters. Instead of continuously analyzing all possible environment variables, the UE compares current conditions against pre-established environment profiles, reducing processing complexity while maintaining adaptation capability.
Solution Approach 2:
The environment recognition system serves multiple functions: it identifies the current communication environment, determines optimal communication parameters, and adapts transmission settings. By consolidating these functions into a unified environment-aware framework, the system achieves comprehensive optimization without proportionally increasing device complexity.
