Workload-Aware Monitoring for AI-RAN
Babak Azkaei, Georgios Exarchakos, Kishor Chandra Joshi
AI-RAN platforms are expected to share CPU and GPU resources between radio workloads and AI services. Aggregate telemetry reports operating conditions, but timing changes may refle…
Controlled Radio Fault Injection and Telemetry Evaluation for Open 5G RANs
Babak Azkaei, Maxim Bîtiu, Georgios Exarchakos +1
Radio access network (RAN) telemetry reveals radio conditions, protocol behavior, and their consequences for applications. Evaluating its usefulness requires controlled impairments…
System-Aware Adaptive CSI Feedback via RL-Guided Autoencoder Switching in Multi-User MIMO System
Maryam Ansarifard, Mohit K. Sharma, George Exarchakos +1
This paper proposes a system-aware adaptive channel state information (CSI) feedback framework for massive multiple-input multiple-output (mMIMO) systems, aiming to dynamically opt…
CSI Compression Beyond Latents: End-to-End Hybrid Attention-CNN Networks with Entropy Regularization
Maryam Ansarifard, Mostafa Rahmani, Mohit K. Sharma +3
Massive MIMO systems rely on accurate Channel State Information (CSI) feedback to enable high-gain beam-forming. However, the feedback overhead scales linearly with the number of a…
Discrete Time Credit-Based Shaping for Time-Sensitive Applications in 5G/6G Networks
Anudeep Karnam, Kishor C. Joshi, Jobish John +3
Future wireless networks must deliver deterministic end-to-end delays for workloads such as smart-factory control loops. On Ethernet these guarantees are delivered by the set of to…
