Partnership researches 6G joint communication and sensing
The China Mobile Research Institute and Rohde & Schwarz have joined forces to research and validate 6G joint communication and sensing (JCAS). They are using the latest AREG800A automotive radar echo generator from Rohde & Schwarz as an object simulator in a JCAS testing system, 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. Joint communication and sensing 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/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 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 systems. 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 system in which they used the latest AREG800A as an object simulator. This system 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 system 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 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 AREG800A can simulate several target objects by increasing the number of frontends. Various frequency converter modules allow the AREG800A to perform JCAS testing in specific frequency bands.
Dr. Liu Guangyi, Chief Expert at the China Mobile Communications Corporation, says, “The mission of 6G is to expand mobile network capabilities and boundaries to enable the vision of digital twins and ubiquitous intelligence, which requires continuous collaboration and innovation from the industry. The 6G team at the China Mobile Research Institute and Rohde & Schwarz are collaborating on JCAS and look forward to finding a consensus on scenarios, requirements and key technologies while developing a solid foundation for future standardization and industrialization.”
Hailiang Jin, Senior Director Product and System at Rohde & Schwarz, says: “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.”
