OCUDU Ecosystem Developer Summit

Integrated Sensing and Communication (ISAC) is emerging as a key 6G capability, but enabling sensing in a real cellular stack requires exposing rich PHY measurements without disrupting real-time operation.

This talk presents lessons from two open-source cellular prototypes and how they can inform ISAC support in OCUDU. MIMO-RIC extends the srsRAN 5G stack with UCSD’s EdgeRIC controller to expose per-antenna, per-subcarrier PUSCH/DMRS channel estimates and feed control policies back to the RAN. Its over-the-air prototype demonstrates localization, interference monitoring, and MIMO nulling with

This session presents a practical implementation of monostatic integrated sensing and communication (ISAC) using an OCUDU-based 5G NR network and software-defined radio hardware. We demonstrate how an operational 5G downlink waveform can be reused for radar sensing without requiring a dedicated radar waveform or a cooperating UE. The presentation will cover the system architecture, acquisition of a local transmit reference, synchronization, OFDM-based channel estimation, and range-Doppler processing. We will also share experimental results from real-world sensing tests involving people, vehicles, and drones, along with practical lessons learned while extending an open-source 5G RAN platform beyond communications.

This 30 minutes short session will unlock the full potential of enterprise private 5G by mastering Distributed MIMO (D-MIMO) on the O-CU/DU framework. Also provides a comprehensive look at how D-MIMO is redefining industrial connectivity. Attendees will explore the practical implementation of this technology alongside real-world use cases, including tactical VR training for defense and law enforcement, AI-powered camera networks in high-density smart manufacturing, and ISAC (Integrated Sensing and Communication) data aggregation. We will break down the key engineering challenges encountered during development/deployment and demonstrate the tangible benefits of D-MIMO—specifically its ability to eliminate coverage dead zones, reduce interference and guarantee reliable, high-bandwidth communication.

Supporting airborne and high-speed unmanned systems in test ranges requires wireless networks engineered for extreme distance, velocity, and mobility—challenges that extend well beyond conventional 5G deployments.

This presentation outlines the capabilities needed to adapt O-CUDU architectures for 5G and FutureG test range operations. We will explore how to enable very large airspace cells and support high-mobility UEs by maximizing existing 3GPP mechanisms, including extended Cyclic Prefix, RACH formats, and extended window searches. The discussion will also introduce potential beyond-standard enhancements. Specifically, we will focus on addressing gNB-side Doppler compensation and deploying advanced mobility management. By building upon standardized techniques like conditional handover, such enhanced mechanisms can improve link reliability and seamless transitions in highly dynamic scenarios.

Additionally, the talk will highlight the structural overlap with Non-Terrestrial Network (NTN) standards, demonstrating how NTN-driven advances can secure robust connectivity for dynamic range users.
