Terminal Logging Control for Wireless Interference Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User devices in wireless communication systems face challenges in detecting and reporting interference from in-device communication, particularly when determining the impact of interference on LTE downlinks, which affects logging operations and requires varying logging methods based on interference levels and capabilities to generate or transmit interference indicators.
Innovation Solution
A method for user devices to determine whether LTE downlinks are affected by interference, deciding whether to perform logging based on the clarity of interference, and adjusting logging operations accordingly, including using IDC indicators to transmit information about potential interference to the network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the user device performs logging of measurement for downlink, then the network can obtain measurement data for optimization, but the logging consumes device resources and may log inaccurate data when interference is present
Solution Approach 1:
The patent applies dynamics by making the logging operation conditional rather than static. The device dynamically adjusts whether to perform logging based on real-time interference detection results. When interference is detected, logging is suspended; when no interference is present, logging proceeds normally. This dynamic adjustment resolves the contradiction by ensuring measurement accuracy only when conditions permit, thereby avoiding waste of device resources on logging inaccurate data.
2Reliability
If the user device transmits interference indicator to the network, then the network can take corrective actions, but the device requires additional capabilities to generate and transmit the indicator
Solution Approach 1:
The patent applies local quality by providing different logging behaviors for different frequency portions based on local interference conditions. The device detects interference on specific frequencies and adjusts logging accordingly - suspending logging only on affected frequencies while continuing on non-affected frequencies. This localized approach resolves the contradiction by enabling targeted interference notification without requiring comprehensive device capabilities across all operations.
3Measurement precision
If the user device suspends logging when interference is detected, then logging accuracy is maintained, but the network receives less measurement data for optimization
Solution Approach 1:
The patent applies segmentation by dividing the logging operation into interference-affected and non-affected portions. Instead of suspending all logging when any interference is detected, the device segments the logging based on frequency or time portions - suspending logging only where interference occurs while continuing logging in clean portions. This segmented approach resolves the contradiction by maintaining measurement precision in affected areas while preserving productivity through continued logging in unaffected areas.
