Rohde & Schwarz and China Mobile Research Institute 6G JCAS research

They plan to use the latest R&S AREG800A automotive radar echo generator from Rohde & Schwarz as an object simulator in JCAS testing, thereby accelerating the research and development of JCAS and readying it for industrialisation.

There are many goals and requirements for 6G, and several technologies that have emerged to meet them are now used in 6G research. Joint communication and sensing are based on 6G sensing requirements and have become an important candidate technology in the wireless industry.

The technology focuses on fulfilling native JCAS design requirements with multiple-signal designs and/or hardware sharing. JCAS can sense direction, distance, and speed during information exchanges as well as velocity. JCAS can also detect, track, identify and create images of the target equipment, event, or environment for interconnection between communications and sensing equipment to improve overall system performance.

The China Mobile Research Institute is an industry specialist in several technologies and has a long-term commitment to researching new 6G technologies, developing prototypes and verifying technologies.

From early on, Rohde & Schwarz has been actively involved in national and international 6G research projects and organisations and in the development of accompanying test solutions.

Both parties have joined forces to research and validate JCAS and already have several accomplishments under their belt. The China Mobile Research Institute and Rohde & Schwarz recently developed a JCAS testing solution in which they used the latest R&S AREG800A as an object simulator.

This platform can simulate a target object’s distance, angle, velocity, and other parameters to verify the ability of a system under test to precisely locate a target object. The platform enables reliable and repeatable testing in the lab, accelerating the research and development of JCAS and preparing it for industrialisation.

Currently, most industrial technologies used to validate and test sensing capabilities are based on real objects with limited test scenarios in inflexible settings. The R&S AREG800A is the latest dynamic artificial object simulator from Rohde & Schwarz and can generate multiple dynamic targets with varying distances, sizes, radial velocities, and angular directions.

The R&S AREG800A can simulate several target objects by increasing the number of frontends. Various frequency converter modules allow the R&S AREG800A to perform JCAS testing in specific frequency bands.

Hailiang Jin, Senior Director Product and System at Rohde & Schwarz, says: “We are glad to see the industry-leading 6G JCAS results from the collaboration between Rohde & Schwarz and the China Mobile Research Institute. We hope that further collaboration will allow both parties to make more breakthroughs here and fully validate the capability of 6G networks to sense the physical world. We also hope that both parties will be able to collaborate on other key 6G technologies and open up a new era of 6G.”
