OCUDU-RAN rfsimulator: A Scalable Multi-UE Foundation for AI-RAN and 6G
This release introduces native integration of OpenAirInterface (OAI) rfsimulator into OCUDU-RAN, enabling scalable multi-UE simulation through a single radio simulation endpoint. Building on the earlier ZMQ-based multi-UE setup, the new integration supports up to 50 concurrent OAI UEs connected to a single OCUDU gNB on one machine. The release includes: Multi-peer rfsimulator integration Slot-level sample combining across UEs Automated multi-UE testing Isolated UE network namespaces Concurrent DL and UL traffic testing Radio and lower-PHY performance optimisations At 8 UEs, aggregate DL throughput improved from 67.05 Mbps to 106.25 Mbps, a 58% improvement. At 50 UEs, 50/50 UE attachment was achieved with the OAI core. This provides a scalable software foundation for experiments across AI-RAN, intelligent scheduling, network slicing, NTN, digital twins and other 6G applications.
