Publication number: 20240365291Abstract: Embodiments of the present disclosure relate to a method of sensing signal handling. A sensing signal transmission procedure is triggered by a transmitting node or a receiving node. A sensing signal is transmitted the transmitting node, which is received by the receiving node. In case the transmitting node triggers the sensing signal transmission procedure, the transmitting node sends a request including a configuration of the sensing signal to the receiving node, the transmitting node asks the receiving node to receive the sensing signal based on the configuration, and the transmitting node transmits the sensing signal based on the configuration. In case the receiving node triggers the sensing signal transmission procedure, the receiving node sends a request including a suitable configuration of the sensing signal to the transmitting node, and the transmitting node transmits the sensing signal based on the suitable configuration to the receiving node.Type: ApplicationFiled: April 25, 2023Publication date: October 31, 2024Applicant: Rohde & Schwarz GmbH & Co.

Patent number: 9780890Abstract: A measuring system for measuring a communications device comprising an antenna-array. The measuring system comprises a controller, a measuring device, a measuring antenna and a device mount. The measuring device performs measurements with regard to the communications device. The device mount rotates the communications device about at least one axis. The controller sets a maximum gain direction of the antenna-array. The controller (i) controls the device mount to rotate the communications device, compensating for the set maximum gain direction, until the set maximum gain direction meets a direction of the measuring antenna with respect to the communications device, and (ii) determines an actual maximum gain direction of the antenna-array by iteratively rotating the communications device and determining a respective gain for each iteration, and determines the actual maximum gain direction as a rotation of the device mount that corresponds to the iteration of maximal gain.Type: GrantFiled: June 2, 2016Date of Patent: October 3, 2017Assignee: Rohde & Schwarz GmbH & Co.
