China Mobile Research Institute is teaming up with Rohde & Schwarz to research and validate joint communication and sensing (JCAS) for next generation 6G systems.

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

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 and 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.

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 dynamic artificial object simulator generate multiple dynamic targets with varying distances, sizes, radial velocities and angular directions. The test system can simulate several target objects by increasing the number of frontends and various frequency converter modules allow simulation and JCAS testing in specific frequency bands.

Rohde & Schwarz has been actively involved in national and international 6G research projects and organizations and in the development of accompanying test solutions.

“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,” said Dr. Liu Guangyi, Chief Expert at the China Mobile Communications Corporation. “We are glad that the 6G team at the China Mobile Research Institute and Rohde & Schwarz can collaborate on JCAS and we look forward to deepening this collaboration to find 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 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.”
