Rohde & Schwarz, China Mobile work on future 6G tech

The partners recently developed a JCAS testing solution in which they used the latest R&S AREG800A automotive radar echo generator as an object simulator

The China Mobile Research Institute and test company Rohde & Schwarz are partnering to research and validate joint communication and sensing (JCAS).

The two partners intend to use Rohde & Schwarz’s most recently released automotive radar echo generator as an object simulator in a JCAS testing solution. R&S said that its test solution is far more flexible than the set-ups used for JCAS testing currently, which it described as being “based on real objects with limited test scenarios in inflexible settings.” Comparatively, the test company said, its dynamic artificial object simulator “can generate multiple dynamic targets with varying distances, sizes, radial velocities and angular directions” and can also “simulate several target objects by increasing the number of frontends.”

Rohde & Schwarz noted that joint communication and sensing has become an important candidate 6G technology. JCAS can sense direction, distance, speed and velocity during information exchanges and can detect, track, identify and create images of target equipment, events or environments, the test company said.

The China Mobile Research Institute and Rohde & Schwarz recently developed a JCAS testing solution in which they used the latest R&S AREG800A automotive radar echo generato 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 a target object. The solution enables reliable and repeatable testing in the lab, accelerating the research and development of JCAS and preparing it for industrialization, the companies said.

Liu Guangyi, chief expert at the China Mobile Communications Corporation, said: “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. 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.”

“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,” said Hailiang Jin, senior director of product and system at Rohde & Schwarz.

Earlier this year, Rohde & Schwarz announced it will take part in 6G-ANNA, a so-called “lighthouse” project to advance 6G technology in Germany.

The three-year 6G-ANNA project was launched by the German Federal Ministry of Education and Research and is led by Nokia.

The participating consortium of 29 participating companies and research institutions aims to advance the development, standardization and implementation of the next generation of mobile communications in Germany.

Rohde & Schwarz noted that the first global specification of 6G is expected within the next six to eight years, and the commercial introduction of the technology is estimated to take place around 2030.
