Terminal Power Control Parameter Configuration via TCI States
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In next-generation radio communication systems, determining an appropriate power control parameter for uplink transmission is challenging due to the lack of a clear relationship between Transmission Configuration Indication (TCI) states and power control parameters, leading to reduced communication quality and throughput.
Innovation Solution
A terminal equipped with a receiving section for information related to TCI states and a control section that determines power control parameters for uplink transmission, allowing for appropriate configuration and indication of these parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a TCI state is applied to multiple types of signals without a clear relationship to power control parameters, then the system can maintain simpler configuration, but communication quality and throughput are reduced
Solution Approach 1:
The patent segments the power control parameter configuration by signal type. Different power control parameters (P0, alpha, closed loop index) are separately configured for different signal types (PUCCH, PUSCH, SRS) within the same TCI state, allowing precise control for each signal while maintaining unified TCI state management.
Solution Approach 2:
The patent applies local quality by assigning different power control parameter settings to different signal types within a TCI state. Each signal type can have optimized power control parameters tailored to its specific requirements, improving overall communication quality without requiring complete reconfiguration of the TCI state.
2Ease of operation
If power control parameters are not properly determined for each signal type, then the system operation remains simple, but throughput is reduced
Solution Approach 1:
The patent creates a universal power control parameter configuration mechanism where a single TCI state can contain power control parameters for multiple signal types (PUCCH, PUSCH, SRS). This multi-functional approach allows the system to maintain simple operation while achieving optimized throughput for different signal types through unified yet differentiated parameter management.
