Mobile Terminal–Network Node Reporting for Time-Limited Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems struggle to efficiently manage time-limited interference, which can negatively impact transmission parameters and degrade performance, particularly in environments with short-lived RF interference such as factories, leading to suboptimal adjustments in CQI outer loops and affecting URLLC services.
Innovation Solution
Mobile terminals and network nodes are configured to detect and report time-limited interference, allowing network nodes to take remedial actions based on these detections, distinguishing between time-limited and background interference to improve network performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mobile terminal performs measurements and reporting of all types of interference, then the network node can take remedial actions, but the signaling overhead and network complexity increase
Solution Approach 1:
The patent segments interference into two distinct categories: time-limited interference and background interference. The mobile terminal independently identifies and reports only time-limited interference to the network node, rather than reporting all interference types. This segmentation reduces signaling overhead and network complexity while maintaining reliable interference management for the critical time-limited case.
Solution Approach 2:
The patent applies local quality by treating different interference types differently. Specifically, the mobile terminal performs specialized detection and reporting for time-limited interference (a local subset of all interference), while background interference is handled through existing mechanisms. This localized approach optimizes resources by focusing detailed measurement and reporting only where needed.
2Reliability
If the network adjusts transmission parameters based on interference measurements, then transmission reliability improves, but the adjustment response time increases due to measurement and reporting delays
Solution Approach 1:
The mobile terminal continuously monitors and identifies time-limited interference in advance, reporting it to the network node before it significantly degrades transmission performance. This preliminary detection and reporting mechanism enables the network node to prepare and execute remedial actions more quickly, reducing the effective response time while maintaining high transmission reliability.
3Productivity
If the mobile terminal reports time-limited interference specifically, then the network can optimize remedial actions, but the measurement and determination complexity increases
Solution Approach 1:
The mobile terminal detects time-limited interference by monitoring changes in interference parameters over time. Specifically, it identifies interference that appears and disappears within a defined time window, distinguishing it from persistent background interference. This parameter-based approach (tracking interference duration and temporal characteristics) enables efficient identification of time-limited interference without excessive complexity, allowing the network to optimize remedial actions based on precise interference classification.

AI summary
A method of detecting interference in a mobile telecommunications network, the mobile telecommunications network comprising a mobile terminal and a network node providing a wireless access interface to at least the mobile terminal. The method comprises the mobile terminal performing measurements of interference on one or more frequency resources of the wireless access interface; based on the measurements, the mobile terminal determining that the measured interference comprises time-limited interference by determining whether the measured interference comprises interference limited in time; upon determining that the measured interference comprises time-limited interference, the mobile terminal reporting to the network node the detection of the time-limited interference; the network node receiving a report of the time-limited interference detection from the mobile terminal; and the network node taking a remedial action based on receiving the report of the time-limited interference detection.
