Resilience under Uncertainty: Securing 6G through Stochastic Reinstantiation of RAN Functions
Gabriel Almeida, Jacek KibiÅda, Joao F. Santos +1
The disaggregation of base stations into discrete RAN functions introduces new threats to mobile networks, as failures in one RAN function can trigger cascading failures and interr…
Conflict Detection in AI-RAN: Efficient Interaction Learning and Autonomous Graph Reconstruction
Joao F. Santos, Arshia Zolghadr, Scott Kuzdeba +1
Artificial Intelligence (AI)-native mobile networks represent a fundamental step toward 6G, where learning, inference, and decision making are embedded into the Radio Access Networ…
On the Robustness of RSMA to Adversarial BD-RIS-Induced Interference
Arthur S. de Sena, Jacek Kibilda, Nurul H. Mahmood +3
This article investigates the robustness of rate-splitting multiple access (RSMA) in multi-user multiple-input single-output (MISO) systems to interference attacks against channel…
Adaptive Reallocation of RAN Functions for Resilient 6G Networks
Gabriel M. Almeida, Jacek KibiÅda, Joao F. Santos +1
The disaggregation of base stations into discrete RAN functions introduces new threats to mobile networks, as failures in one RAN function can trigger cascading failures and disrup…
Dimensioning and Optimization of Reliability Coverage in Local 6G Networks
Jacek KibiÅda, Dian EchevarrÃa Pérez, André Gomes +4
Enabling vertical use cases for the sixth generation (6G) wireless networks, such as automated manufacturing, immersive extended reality (XR), and self-driving fleets, will require…
Learning and Reconstructing Conflicts in O-RAN: A Graph Neural Network Approach
Arshia Zolghadr, Joao F. Santos, Luiz A. DaSilva +1
The Open Radio Access Network (O-RAN) architecture enables the deployment of third-party applications on the RAN Intelligent Controllers (RICs). However, the operation of third-par…
