Rohde & Schwarz and China Mobile Research Institute collaborate on 6G JCAS research and early validation

20 September 2022

The China Mobile Research Institute and Rohde & Schwarz have joined forces to research and validate joint communication and sensing (JCAS). They plan to use the latest R&S AREG800A automotive radar echo generator from Rohde & Schwarz as an object simulator in a JCAS testing solution, thereby accelerating the research and development of JCAS and readying it for industrialization.

6G has many new goals and requirements, and several new technologies have emerged to meet them that are now used in 6G research. JCAS is based on 6G sensing requirements and has become an important candidate technology in the wireless industry. The technology focuses on fulfilling native JCAS design requirements with multiple-signal designs and hardware sharing. JCAS can sense direction, distance and speed during information exchanges as well as velocity. The technology can also detect, track, identify andSource: Rohde & SchwarzSource: Rohde & Schwarz 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 leader 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 organizations 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 solution can simulate a target object’s distance, angle, velocity and other parameters to verify the ability of a system under test to precisely locate the target. The solution enables reliable and repeatable testing in the lab, accelerating the research and development of JCAS and preparing it for industrialization.

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.
