Failure Report Generation for Device Co-Existence Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in accurately reporting device co-existence interference, which can lead to incorrect network performance evaluations and sub-optimal network organization due to interference between collocated radio transceivers, particularly in scenarios like LTE and ISM band coexistence.
Innovation Solution
The method involves determining device co-existence interference during communications failures and generating failure reports that include indicators of such interference, which are then used to adjust reporting operations, such as requesting reconnection or modifying report indicators, to prevent the transmission of incorrect data and optimize network performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If failure reports are generated without distinguishing device co-existence interference, then reporting simplicity is maintained, but measurement precision deteriorates due to incorrect network performance evaluation
Solution Approach 1:
The failure report is segmented into multiple parts: a basic failure report containing standard failure variables, and an optional extended failure report containing device co-existence interference indicators. The network can request only the basic report or both reports depending on the situation, allowing the device to maintain the capability to provide detailed information without always generating it.
Solution Approach 2:
The device performs partial reporting by sending only the essential failure information in the basic report, and only adds the interference indication in the extended report when specifically requested or when the interference is severe. This partial action approach maintains measurement precision when needed while reducing complexity in normal operations.
2Measurement precision
If device co-existence interference indicators are always included in failure reports, then measurement precision is improved, but loss of time increases due to extended reporting overhead
Solution Approach 1:
The extended failure report with interference indicators is transmitted periodically or on-demand based on network requests rather than continuously. The network can configure the device to send extended reports only under specific conditions or at specific times, reducing the time loss while maintaining measurement precision when needed.
3Loss of information
If failure reports are transmitted without filtering, then productivity is maintained, but loss of information occurs due to transmission of incorrect or misleading data
Solution Approach 1:
The device performs preliminary determination of device co-existence interference status before generating the failure report. This preliminary action allows the device to include accurate interference indicators in the report from the outset, preventing loss of information about the actual failure cause while maintaining reporting efficiency by avoiding post-processing corrections.
