Innovation Solution
A method where user equipment (UE) receives configuration information and control information for uplink data channel transmission, using transmission units and beams based on uplink or downlink reference signals, including sounding reference signal resources, CSI-RS resources, or synchronization signal block identifiers, to perform panel and beam unit scheduling and power control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If uplink transmission is controlled without panel and beam unit configuration, then device complexity is reduced, but power control precision and transmission efficiency deteriorate
Solution Approach 1:
The patent segments the uplink transmission control into panel-level and beam-level configurations. Each panel can be independently configured with its own beam settings, allowing precise power control at granular levels without requiring complete reconfiguration of the entire transmission system. This segmentation enables targeted adjustments to specific panels or beams while maintaining overall system simplicity.
Solution Approach 2:
The patent applies local quality by allowing different power control parameters and beam configurations for different panels and beams. Each panel- beam combination can have customized settings optimized for its specific transmission characteristics, rather than applying uniform configuration across all transmission units. This enables precise local optimization while maintaining manageable overall complexity.
2Productivity
If multiple transmission units and beams are configured for uplink data channel, then transmission efficiency is improved, but scheduling complexity increases
Solution Approach 1:
The patent divides the transmission system into independent panel and beam units that can be individually scheduled. Each panel-beam pair operates as a discrete transmission resource, allowing the base station to activate only the necessary units for each transmission task. This segmentation improves transmission efficiency by enabling parallel operations while keeping scheduling complexity manageable through modular resource allocation.
Solution Approach 2:
The patent implements dynamic panel and beam selection where the base station can activate, deactivate, or reconfigure specific panels and beams based on current transmission requirements. This dynamic approach allows the system to adapt transmission resources in real-time, improving efficiency by using only necessary resources while maintaining scheduling simplicity through on-demand configuration.
3Measurement precision
If panel and beam unit configuration is implemented, then power control is enhanced, but energy consumption increases
Solution Approach 1:
The patent segments power control into panel-level and beam-level configurations, enabling precise power management for each transmission unit. This segmentation allows the system to apply power control only where needed rather than uniformly across all transmission resources, improving power control precision while minimizing unnecessary energy consumption in inactive or less critical transmission units.
Solution Approach 2:
The patent enables dynamic activation and deactivation of panels and beams based on transmission requirements. When certain panels or beams are not needed for current transmission tasks, they can be deactivated to conserve energy, while maintaining the capability to quickly reactivate them when needed. This approach enhances power control by matching energy consumption to actual transmission demands.
