Victim-Aggressor Verification for Secure Remote Interference Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems are vulnerable to malicious nodes masquerading as victims, leading to unnecessary remote interference mitigation schemes that degrade network performance.
Innovation Solution
A central entity verifies legitimate victim-aggressor pairs by checking the reports from gNBs, ensuring that only legitimate gNBs trigger remote interference mitigation, thereby preventing malicious nodes from triggering unnecessary mitigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If remote interference mitigation is triggered based on victim reference signal detection, then interference protection is improved, but network security deteriorates due to vulnerability to masquerade attacks
Solution Approach 1:
The patent introduces a central entity (OAM) as an intermediary between victim and aggressor gNBs. This intermediary verifies the legitimacy of detected victim reference signals by checking against a whitelist of authorized gNB identifiers, preventing malicious nodes from triggering false mitigation while allowing legitimate interference protection to proceed
Solution Approach 2:
The system implements feedback mechanisms where the central entity receives detection reports from victim gNBs, verifies their legitimacy, and provides confirmation or rejection feedback. This feedback loop ensures that only verified legitimate detections trigger mitigation, creating a closed-loop security verification system
2Object-affected harmful factors
If verification of victim-aggressor pairs is implemented, then network security is improved, but system complexity increases
Solution Approach 1:
The patent uses identifier copying and matching - the central entity maintains a whitelist of authorized gNB identifiers and compares detected identifiers against this copy. This simple copy-and-compare approach provides verification without requiring complex authentication protocols or additional hardware
Solution Approach 2:
The central entity performs multiple functions including interference coordination, verification, and management using a single unified platform. This multi-functionality avoids the need for separate dedicated verification systems, reducing overall system complexity while maintaining security

AI summary
Disclosed herein are system, method, and computer program product embodiments verifying legitimate victim-aggressor pairs in remote interference management operation. In an embodiment, a first even report is generated by a victim base station based detection of an atmospheric duct and it transmits a victim reference signal with the first event report. The first event report includes an ID of the victim base station. An aggressor base station is triggered to begin monitoring for transmission of the victim reference signal. The aggressor base station sends a second event report if it detects the victim reference signal. The central entity tries to verify that the victim and aggressor are legitimate. If the verification passes, then the central entity sends a message to the aggressor to start of remote interference mitigation. If verification fails, the remote interference mitigation is not triggered and the victim reference signal is ignored.
