Abstract
A method for obtaining an angle of departure (AOD) of a terminal, comprising: angle measuring signals are sent to a receiving terminal at a plurality of sending positions; corresponding phase information of the angle measuring signals, sent by the receiving terminal, of the plurality of sending positions is received; and the AOD of the sending terminal is obtained according to the phase information of the angle measuring signals.
Claims17
A method for obtaining an angle of departure (AOD) of a terminal, performed by a sending terminal, comprising:
- sending angle measuring signals to a receiving terminal at a plurality of sending positions;
- receiving phase information, sent by the receiving terminal, of the angle measuring signals corresponding to the plurality of sending positions;
- and
- obtaining, according to the phase information of the angle measuring signals, the AOD of the sending terminal;
- wherein sending the angle measuring signals to the receiving terminal at the plurality of sending positions comprises:
- sending the angle measuring signals with same antenna at the plurality of sending positions;
- or
- sending angle measuring signals with same antenna at some of the plurality of sending positions, and sending angle measuring signals with different antennas at the other sending positions;
- wherein before sending the angle measuring signals to the receiving terminal at the plurality of sending positions, the method further comprises:
- sending a capability negotiation request to the receiving terminal, wherein the capability negotiation request is configured to negotiate whether the receiving terminal supports AOD measurement based on a phase;
- and
- receiving a capability negotiation request response sent by the receiving terminal, wherein the capability negotiation request response is configured to indicate whether the receiving terminal supports the AOD measurement based on the phase;
- wherein the capability negotiation request is sent or the capability negotiation request response is received through a terminal capability enquiry sidelink or a terminal capability information sidelink.
