UE Polarization Mode Selection from SSB Measurements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, particularly in the context of Long Term Evolution (LTE) and New Radio (NR), face limitations in flexibility and efficiency, especially in managing polarization modes and resource grid configurations, which affect communication quality and efficiency, especially in non-terrestrial networks (NTN) scenarios.
Innovation Solution
The system employs a user equipment (UE) with a receiver to measure and select polarization modes based on information included in Synchronization Signal Blocks (SSBs) and transmits measurement reports, using OFDM symbols and resource grids configured for optimal communication, enabling flexible and efficient communication by adapting to the best measurement results and polarization modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed communication structure is used, then system simplicity is maintained, but communication flexibility and efficiency are limited
Solution Approach 1:
The patent implements dynamic polarization mode selection where the UE measures SSB signals and selects the optimal polarization mode (first or second mode) based on measurement results. This dynamic adaptation allows the communication system to adjust to varying channel conditions, improving flexibility and efficiency without requiring a completely complex restructured system
Solution Approach 2:
The system changes the polarization mode parameter based on SSB measurement results. The UE measures reference signals in different polarization modes and selects the mode with better signal quality, thereby optimizing communication performance through parameter adjustment rather than structural complexity
2Productivity
If polarization mode selection is implemented based on SSB measurements, then communication efficiency is improved, but device complexity increases
Solution Approach 1:
The system performs preliminary polarization mode measurement during the SSB reception phase. The UE measures the SSB signal in both first and second polarization modes beforehand, stores the measurement results, and selects the optimal mode for subsequent communication. This preliminary action avoids real-time complex processing during data transmission, improving efficiency while managing device complexity
Solution Approach 2:
The UE autonomously performs polarization mode measurement, selection, and reporting without requiring complex network-side processing. The terminal device itself services the polarization optimization function by measuring SSB signals, selecting the best mode, and reporting to the base station, thereby improving communication efficiency with minimal additional device complexity
