Method and device for UWB communication

A method performed by a second ultra-wideband (UWB) device in a wireless communication, the method comprising:

• receiving, by a UWB subsystem (UWBS) of the second UWB device from a host of the second UWB device, a first UWB command interface (UCI) message including UWB configuration information for an application, wherein the UWB configuration information for the application includes ranging round usage information indicating one way ranging (OWR) for angle of arrival (AoA) measurement, and device role information indicating an observer that receives a UWB message of the OWR for the AoA measurement;
• and
• receiving, from a first UWB device configured as an advertiser, the UWB message of the OWR for the AoA measurement using UWB communication based on the UWB configuration information,
• wherein the UWB message of the OWR for the AoA measurement includes:
• a class field indicating a class of a data format included in an advertisement data field,
• a data type length field indicating a length of an advertisement data type field,
• the advertisement data type field indicating a type of advertise data,
• an advertisement data length field indicating a length of the advertisement data field, and
• the advertisement data field including the advertise data.

A first ultra-wideband (UWB) device in a wireless communication, the first UWB device comprising:

• a transceiver;
• and
• at least one processor coupled with the transceiver,
• wherein the at least one processor is configured to:
• receive, by a UWB subsystem (UWBS) of the first UWB device from a host of the first UWB device, a first UWB command interface (UCI) message including UWB configuration information for an application, wherein the UWB configuration information for the application includes ranging round usage information indicating one way ranging (OWR) for angle of arrival (AoA) measurement, and device role information indicating an advertiser that transmits a UWB message of the OWR for the AoA measurement, and
• transmit, to a second UWB device configured as an observer, the UWB message of the OWR for the AoA measurement using UWB communication based on the UWB configuration information, and
• wherein the UWB message of the OWR for the AoA measurement includes:
• a class field indicating a class of a data format included in an advertisement data field,
• a data type length field indicating a length of an advertisement data type field,
• the advertisement data type field indicating a type of advertise data,
• an advertisement data length field indicating a length of the advertisement data field, and
• the advertisement data field including the advertise data.
