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.
Claims18
A first device comprising:
- at least one processor;
- and
- at least one memory including computer program code,
- the at least one memory and the computer program code configured to, with the at least one processor, cause the first device to:
- receive, from a location management device, information regarding a first angle of departure, the first angle of departure being expected for transmission of first reference signals from a second device;
- determine, based on the information, a configuration for the transmission of the first reference signals;
- and
- transmit the configuration to the second device.
A second device comprising:
- at least one processor;
- and
- at least one memory including computer program code;
- the at least one memory and the computer program code configured to, with the at least one processor, cause the second device to:
- receive, from a first device, a configuration for transmission of first reference signals, the configuration being determined by the first device based on information regarding a first angle of departure from a location management device, the first angle of departure being expected for the transmission of the first reference signals from the second device;
- and
- transmit, based on the configuration, the first reference signals for positioning of the second device.
A location management device comprising:
- at least one processor;
- and
- at least one memory including computer program code,
- the at least one memory and the computer program code configured to, with the at least one processor, cause the location management device to:
- determining an estimated location of a second device;
- and
- determining a first angle of departure based on the estimated location and a location of a third device for positioning the second device;
- generate information regarding the first angle of departure, the first angle of departure being expected for transmission of first reference signals from the second device;
- and
- transmit the information to a first device.
A method of communication, comprising:
- at a location management device:
- determining an estimated location of a second device;
- determining a first angle of departure based on the estimated location and a location of a third device for positioning the second device;
- generating information regarding the first angle of departure, the first angle of departure being expected for transmission of first reference signals from the second device;
- and
- transmitting the information to a first device.
