The O-RAN Alliance is preparing to release the first O-RAN standard Open Fronthaul Specifications comprised of control, user, synchronization and management plane protocols.
Sachin Katti, Stanford University Professor and O-RAN TSC co-chair said, “we are excited to release the first O-RAN Open Fronthaul Specification. O-RAN has leveraged significant specification work done in xRAN and will accelerate interoperability testing and product commercialization. Further, the O-RAN fronthaul workgroup has also started discussions on potential new study items to pursue for 2019.”
At next week's MWC19 in Barcelona, O-RAN Alliance members will showcase six strategic proof-of-concepts across various member booths covering four key themes: intelligent RAN control, Open Interfaces, virtualization and white box.
Highlights of the demos
- "O-RAN aligned implementation of Radio Intelligent Controller (RIC) Load Balancing" showcases predictive load balancing using Smart Radio Fingerprint technology that provides opportunities to interoperability using O-RAN architecture interfaces and established industry elements. The solution enables the accurate redirection of UE attachment, optimized load balancing, and improved user experience. This demo is being sponsored and hosted by China Mobile and ZTE at their respective booths.
- “AI empowered User Quality of Experience (QoE)” showcases predictive user QoE enabled by machine learning micro services chained together, to autonomously recognize traffic types in real-time, predict quality and provide closed-loop network controls resulting in a consistent, high-quality 5G user experience. This demo is being sponsored by China Mobile and Nokia; and hosted in the China Mobile booth.
- “Open Fronthaul Interface” showcases the use of O-RAN’s Open Front Haul specification with a variety of vendors to achieve interoperability between the O-DU and O-RU enabled by a fully specified control, user, synchronization and management plane protocols. This demo is being sponsored by Verizon, NTT DOCOMO, KT Corporation, SK telecom, Fujitsu, HFR, Intel, Keysight, Mavenir, NEC and SOLiD; and hosted by NTT DOCOMO, KT Corporation, Keysight, Mavenir and NEC at their respective booths.
- “Virtualized O-CU on Akraino edge cloud orchestrated by ONAP” -- showcases the integration of virtualized CU with a community supported Akraino edge stack blueprint packaged into a “cloud appliance” enabling the flexibility of virtualization and cloud, while retaining the simplicity and low cost of an appliance. This demo is being sponsored by AT&T and Nokia; and hosted in the Nokia booth.
- “Programmable mmWave White-Box Radio Unit,” showcases a mmWave smart O-RU transmitting a 5G NR signal with 100MHz bandwidth using a 5G open RAN test platform and a 28 GHz ORU whitebox with a beamformed active antenna system to two UEs test emulators. This demo is being sponsored by AT&T, Anokiwave, Ball Aerospace, Xilinx and Keysight; and hosted in the Xilinx booth.
- “Open hardware reference design for sub 6GHz indoor coverage” showcase two live demos of white-box and general-purpose hardware supporting sub 6GHz indoor coverage deployment scenarios for both 4G and 5G. The first demo is being sponsored by China Mobile, Lenovo, Baicells; and hosted at Lenovo booth. The second demo is being sponsored by China Telecom, Intel, H3C; and hosted in the Intel booth.
