Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Communication failures, such as radio link failures, pose challenges in wireless communications, making it difficult to compensate for these failures effectively.
Innovation Solution
Systems and methods are developed to generate and transmit radio link failure reports that indicate packet duplication, allowing devices to adjust configuration parameters and improve communication by promoting more effective handovers and reducing further errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If radio link failure reports are generated and transmitted to indicate packet duplication, then communication resilience is improved, but device complexity increases
Solution Approach 1:
The failure report is segmented to include only essential information elements (IEs) such as failure type, cell ID, and packet duplication indication. This selective segmentation reduces the complexity of report generation and processing while maintaining the reliability benefit of informing the network about link failures and duplication status.
Solution Approach 2:
The patent extracts and transmits only the critical failure information elements needed for network recovery decisions, rather than reporting all possible parameters. This extraction approach improves communication resilience by providing timely failure notification while minimizing the complexity overhead of processing and transmitting extensive failure data.
2Productivity
If configuration parameters are adjusted based on failure reports, then communication efficiency is improved, but the difficulty of detecting and measuring failure conditions increases
Solution Approach 1:
The patent implements a feedback mechanism where the wireless device monitors radio link quality, detects failures, and reports them to the network. The network then adjusts configuration parameters based on this feedback. This closed-loop feedback system improves communication efficiency by enabling dynamic adaptation while providing clear detection and measurement criteria for failure conditions through standardized reporting protocols.
Solution Approach 2:
The patent establishes preliminary detection thresholds and reporting triggers before failures occur. The device continuously monitors radio link quality against predefined thresholds and automatically triggers failure reports when conditions are met. This preliminary preparation simplifies the detection and measurement process by having predetermined criteria ready, rather than requiring complex real-time analysis during failure events.
