Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In future radio communication systems, the challenge of appropriately controlling transmission power during multi-panel simultaneous transmission has not been clarified, which can inhibit effective communication throughput.
Innovation Solution
A terminal and base station are designed to receive multiple downlink control information signals scheduling physical uplink channels for different panels, and determine transmission power by assuming either multi-panel or single-panel simultaneous transmission, using equations tailored for each panel to manage power effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multi-panel simultaneous transmission is supported to improve throughput and reliability, then communication performance is improved, but transmission power control becomes unclear and may reduce communication throughput
Solution Approach 1:
The patent segments the transmission power control into panel-specific control mechanisms. Each panel is assigned its own power control parameters and control signals, allowing independent power management for each panel while maintaining overall system coordination. This segmentation resolves the complexity by breaking down the multi-panel power control into manageable unit-level controls.
Solution Approach 2:
The patent applies local quality by assigning different power control characteristics to different panels based on their specific transmission conditions. Each panel can have customized power control parameters tailored to its local transmission requirements, enabling optimized power management for each panel's specific scenario while supporting multi-panel simultaneous transmission.
2Productivity
If multi-panel simultaneous transmission is used to enhance throughput, then communication throughput is improved, but transmission power control is not clarified which may reduce throughput
Solution Approach 1:
The patent implements feedback mechanisms where the base station receives power control signals from the terminal for each panel and adjusts transmission parameters accordingly. This feedback loop enables dynamic power control adaptation, ensuring optimal throughput by continuously monitoring and adjusting power levels based on actual transmission conditions for each panel.
Solution Approach 2:
The patent utilizes parameter changes by dynamically adjusting power control parameters for each panel based on transmission conditions. The system changes power levels, bandwidth, and other parameters in response to channel conditions, enabling the system to adapt to varying throughput requirements and maintain optimal communication performance across multiple panels.

AI summary
A terminal according to one aspect of the present disclosure includes a receiving section that receives two downlink control informations (DCIs), the two DCIs scheduling two physical uplink control channels (PUCCHs) overlapped in time, the two PUCCHs being related to different panels, and a control section that determines transmission power for the two PUCCHs by assuming at least one of multi-panel simultaneous transmission and single-panel transmission. According to one aspect of the present disclosure, transmission power control when multi-panel simultaneous transmission is supported can be appropriately performed.
