Title:
METHOD AND APPARATUS FOR PERFORMING A BEAMFORMED TEST SIGNALING
Document Type and Number:
WIPO Patent Application WO/2023/123042
Kind Code:
A1
Abstract:
A method is disclosed for a wireless communication node operating in a wireless communication system and controlling an antenna system. The method comprises obtaining information indicating a direction from the antenna system towards a location of interference sensitivity, and performing beamformed test signaling (e.g., over-the-air transmission of the test signal), wherein a beam direction of the beamformed test signaling and the indicated direction are different. For example, performing the beamformed test signaling may comprise orienting an emission pattern of the beamformed test signaling such that the emission pattern has an emission strength in the indicated direction which is lower than an emission strength threshold. The location of interference sensitivity may comprise a vehicular route, a location of a vehicular control station, or an area of operation of another wireless communication node. In some embodiments, the method is for antenna calibration of the antenna system, and the beamformed test signaling comprises beamformed antenna calibration signaling. Corresponding computer program product, apparatus, and wireless communication node are also disclosed.
