Title:
TRANSMIT BEAFORMING FOR POSITIONING
Document Type and Number:
WIPO Patent Application WO/2022/204842
Kind Code:
A1
Abstract:
Embodiments of the present disclosure relate to a transmit beamforming for positioning. A location management device generates information regarding an angle of departure, the angle of departure being expected for transmission of reference signals for positioning and transmits the information to a device transmitting the reference signals. The device may determine a transmit beamforming solution for transmitting the reference signals based on the angle of departure. In this way, power savings can be achieved due to decreased reference signal overhead. Further, positioning accuracy can be improved through appropriately beamformed reference signal transmissions.
