RF Path Error Detection and UE Capability Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices operating in 5G communication systems face errors in RF paths, leading to offline mode operations, even when other RF paths are error-free, which hampers data transmission and reception efficiency.
Innovation Solution
An electronic device and method that detect errors in RF devices, identify affected RF paths and frequencies, adjust User Equipment (UE) capabilities by modifying or deleting associated information elements, and report the adjustments to the network, allowing communication to continue through error-free paths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electronic device operates in offline mode when an error occurs in the transmit RF path or receive RF path, then communication reliability is improved by avoiding error-prone paths, but data transmission and reception efficiency deteriorates due to inability to utilize error-free RF paths
Solution Approach 1:
The patent segments the RF communication system into multiple independent RF paths, each with its own error status. The processor independently evaluates each RF path and selectively activates only those paths without errors, thereby maintaining reliability while preserving productivity through parallel utilization of multiple error-free paths.
Solution Approach 2:
The patent implements dynamic adjustment of RF path selection based on real-time error detection results. The processor continuously monitors RF path status and dynamically reconfigures which RF paths are active for transmission and reception, transitioning from static offline mode to dynamic selective path activation, thus resolving the contradiction between reliability and efficiency.
2Adaptability or versatility
If the electronic device adjusts UE capability by modifying information elements associated with affected frequencies, then adaptability to error conditions is improved, but device complexity increases due to capability management overhead
Solution Approach 1:
The processor automatically detects RF path errors and autonomously adjusts UE capability information elements without external intervention. The system performs self-diagnosis and self-configuration by modifying capability reports to exclude frequencies associated with error-prone RF paths, thereby achieving adaptability while minimizing complexity through automated self-management.
Solution Approach 2:
The patent changes the parameters of UE capability information elements dynamically based on RF path error status. When errors are detected in specific RF paths, the processor modifies the frequency-related parameters in capability reports to reflect only the error-free RF paths, enabling adaptability through parameter adjustment rather than structural complexity.
