Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 5G NR systems support only single-antenna panel transmission, limiting the potential for simultaneous wireless signal transmission from multiple antenna panels, which is crucial for enhancing system capacity.
Innovation Solution
A method for determining transmission power of wireless signals using a unified design that considers different antenna panels, beams, and spatial characteristics, allowing simultaneous transmission on multiple antenna panels by adjusting power values based on predefined thresholds and coefficients.

Engineering Contradiction Analysis
1Productivity
If terminal equipment is configured with multiple antenna panels, then the system capacity can be improved through simultaneous transmission, but the current standard only supports single antenna panel transmission at a time
Solution Approach 1:
The patent segments the transmission power determination into multiple independent power values (first power value, second power value, third power value) corresponding to different antenna panels and transport blocks. Each power value is determined independently based on its own reference signal resource, allowing simultaneous transmission on multiple antenna panels while maintaining independent power control for each segment.
Solution Approach 2:
The patent creates a universal power determination mechanism that works across different transmission scenarios (single or multiple antenna panels, single or multiple transport blocks). The unified design uses consistent power determination logic based on reference signal resources, making the system adaptable to various configurations without requiring separate mechanisms for each scenario.
2Productivity
If transmission power is determined based on multiple reference signal resources for multiple antenna panels, then simultaneous transmission is enabled, but the power control complexity increases
Solution Approach 1:
The patent enables self-service power control by associating each transport block with its own reference signal resource (first, second, or third reference signal resource). Each power value is automatically determined based on its corresponding reference signal resource without requiring complex centralized coordination, allowing the system to self-manage power distribution across multiple antenna panels.
Solution Approach 2:
The patent performs preliminary power determination by calculating first, second, and third power values based on their respective reference signal resources before actual transmission. This preliminary action allows the system to pre-establish power control parameters for multiple antenna panels, simplifying the real-time transmission process by having power values ready in advance.
