Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power control methods are inadequate for scenarios involving multiple antenna panels transmitting uplink data simultaneously to multiple transmission reception points (TRPs) in a space division manner, as they fail to account for the need to determine distinct output powers for each panel.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single power control parameter set is used for multiple antenna panels, then the device complexity is reduced, but the power distribution precision for each panel deteriorates
Solution Approach 1:
The patent segments the power control parameters by antenna panel, creating separate parameter sets for each panel. This allows independent optimization of power control for each panel while maintaining manageable complexity through structured organization of the segmented parameters.
Solution Approach 2:
The patent applies local quality by allowing different power control parameters to be assigned to different antenna panels based on their specific characteristics and transmission requirements. Each panel can have customized power control settings optimized for its local conditions.
2Manufacturing precision
If separate power control parameters are assigned to each antenna panel, then the power distribution precision is improved, but the device complexity increases
Solution Approach 1:
The patent introduces dynamic selection mechanisms where the terminal can adaptively choose between different power control parameter sets based on real-time conditions. This dynamic approach allows the system to achieve high precision when needed while reducing complexity in other scenarios.
Solution Approach 2:
The patent enables flexible parameter configuration where power control parameters can be changed and selected dynamically. The network can indicate different parameter sets, and the terminal can switch between them based on transmission requirements, achieving precision without permanent complexity.
3Productivity
If power control parameters are not optimized for each antenna panel, then the device complexity is reduced, but the transmission throughput deteriorates
Solution Approach 1:
The patent implements preliminary action by pre-configuring multiple power control parameter sets for different antenna panels before transmission. The network device prepares these parameter sets in advance, and the terminal selects the appropriate ones based on current transmission conditions, achieving optimal throughput without real-time complexity.
4Adaptability or versatility
If multiple power control parameter sets are configured for different antenna panels, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The patent applies universality by designing a unified power control framework that can handle multiple antenna panels with different parameter sets through a common mechanism. The same power control procedure can accommodate various configurations, providing adaptability without proportionally increasing complexity.
