Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional UE power capability reporting methods are used, then the system works for current UE types, but the system lacks scalability and forward-compatibility for future UE power capabilities
Solution Approach 1:
The patent changes the reporting parameter from discrete power class values to a continuous power level range with granularity. Instead of reporting specific power class values that require updates for new UE types, the system reports a range (e.g., 23 dBm with 1 dB granularity) that can accommodate future UE power capabilities without modifying the signaling structure.
Solution Approach 2:
The patent creates a universal reporting mechanism that serves both current and future UE types. The power level range reporting method with predefined granularity can represent any UE power capability within the supported range, making the signaling system multi-functional and eliminating the need for separate signaling for different UE categories.
2Adaptability or versatility
If discrete power class values are used for reporting, then the signaling is simple for current implementations, but the system lacks flexibility for advanced applications like ATG UEs
Solution Approach 1:
The patent transitions from discrete power class parameters to continuous power level parameters with granularity. This allows the system to represent power capabilities with finer precision (e.g., 1 dB steps) while maintaining signaling efficiency through predefined ranges and granularity levels, thus gaining flexibility without sacrificing precision.
Solution Approach 2:
The patent introduces dynamic adaptability by allowing the network to configure the power level range and granularity based on specific application requirements. Different UE types (handheld, ATG, fixed) can utilize appropriate configurations within the same signaling framework, enabling the system to adapt dynamically to various scenarios while preserving detailed power capability information.
