Abstract
A method, computer readable medium, and apparatus for obtaining an angle of departure (AOD). The AOD is obtained by: transmitting a plurality of sweeping beams to a reception terminal; receiving at least one beam identifier, where the at least one beam identifier is determined according to signal quality of the plurality of sweeping beams; and determining a target sweeping beam on the basis of the at least one beam identifier, and determining an AOD of a transmission terminal on the basis of the target sweeping beam.
Claims20
A method for obtaining an angle of departure (AOD), comprising:
- transmitting a plurality of sweeping beams to a reception terminal;
- receiving at least one beam identifier, wherein the at least one beam identifier is determined according to signal quality of the plurality of sweeping beams;
- and
- determining a target sweeping beam based on the at least one beam identifier, and determining an AOD of a transmission terminal based on the target sweeping beam, wherein the AOD of the transmission terminal is equal to a beam azimuth angle of the target sweeping beam;
- wherein the method further comprises:
- transmitting a capability negotiation inquiry to the reception terminal, wherein the capability negotiation inquiry is configured to negotiate whether the reception terminal supports AOD angle measurement based on beams;
- and
- receiving a capability negotiation inquiry response transmitted from the reception terminal, wherein the negotiation inquiry response is configured to indicate whether the reception terminal supports the AOD angle measurement based on beams.
