Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single set of power control parameters is used for all uplink communications, then the device complexity is reduced, but the adaptability to different communication scenarios deteriorates
Solution Approach 1:
The patent divides power control parameters into multiple sets, each associated with different uplink channel types (PUCCH, PUSCH, SRS, PRACH). This segmentation allows the system to select appropriate parameter sets based on the specific channel being used, improving adaptability without significantly increasing overall system complexity.
Solution Approach 2:
The patent introduces dynamic selection mechanisms where the wireless node can switch between different parameter sets based on communication configuration. This includes selecting parameter sets based on uplink channel type, resource allocation mode (grant-based vs. grant-free), and operational scenarios, making the power control system adaptable to varying conditions.
2Productivity
If resource-specific power control parameters are implemented, then the efficiency of uplink transmit power control is improved, but the device complexity increases
Solution Approach 1:
The patent pre-configures multiple sets of power control parameters in advance, each optimized for specific uplink channel types and operational scenarios. This preliminary configuration eliminates the need for real-time parameter calculation, reducing the computational burden and selection complexity while maintaining high efficiency in power control.
Solution Approach 2:
The wireless node autonomously selects the appropriate parameter set based on the type of uplink communication being performed. The node self-determines which parameter set to use based on predefined criteria (channel type, resource allocation mode), eliminating the need for complex external coordination or real-time negotiation.
3Reliability
If multiple parameter sets are configured for different uplink channels, then the communication quality is improved, but the loss of information increases due to configuration complexity
Solution Approach 1:
The patent applies different power control parameter sets to different local contexts (specific uplink channels and scenarios). Each parameter set is locally optimized for its intended purpose, ensuring high communication quality for each channel type while maintaining clear, context-specific configuration rules that reduce management complexity.
