Multiple PTRS Configurations for Wireless Tolerance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication networks face interference and performance degradation due to increasing demand for mobile broadband access, leading to congested networks and reduced tolerance ranges in hardware components like oscillators.
Innovation Solution
Implementing multiple phase tracking reference signal (PTRS) configurations in user equipment (UE) and base stations to support multi-PTRS communication, allowing for different time and frequency domain densities, which compensates for hardware differences and enhances tolerance ranges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple PTRS configurations are implemented in UE and base stations, then tolerance ranges are enhanced and hardware differences are compensated, but device complexity increases
Solution Approach 1:
The patent segments the single PTRS configuration into multiple PTRS configurations, each with different time domain densities and/or frequency domain densities. This segmentation allows the system to handle different hardware characteristics by selecting appropriate configurations, thereby enhancing tolerance ranges while managing complexity through structured division.
Solution Approach 2:
The patent introduces dynamic selection among multiple PTRS configurations based on hardware characteristics and communication conditions. The UE and base station can dynamically choose the most suitable PTRS configuration from multiple options, enabling adaptive compensation for hardware differences and enhancing system reliability without permanently increasing operational complexity.
2Productivity
If multiple PTRS configurations are used with different time and frequency domain densities, then network performance is improved and interference is reduced, but the complexity of configuration management increases
Solution Approach 1:
The patent changes key parameters of PTRS configurations, specifically time domain densities and frequency domain densities, to create multiple distinct configurations. By varying these parameters based on hardware characteristics and channel conditions, the system improves data communication rates and reduces interference while maintaining manageable complexity through parameter-based differentiation.
Data Source
AI summary
A method of wireless communication includes transmitting, by a user equipment (UE) to a base station, a message indicating support of multiple phase tracking reference signal (PTRS) configurations. The method further includes, after transmitting the message, performing a multi-PTRS communication by the UE with the base station. The multi-PTRS communication is performed based on one or more PTRS configurations of the multiple PTRS configurations.
