Abstract
Disclosed is a method of a first ultra-wideband (UWB) device, including identifying an extended MAC address of the first UWB device, generating a short MAC address of the first UWB device based on the extended MAC address, selecting one of the short MAC address and the extended MAC address as a MAC address identifying the first UWB device, and performing UWB communication with a second UWB device, using the MAC address, wherein the second UWB device operates as a controller defining and controlling a control message for UWB ranging, and wherein the first UWB device operates as a controlee using information included in the control message.
Claims18
A method of a first ultra-wideband (UWB) device, comprising:
- identifying an extended medium access control (MAC) address of the first UWB device;
- generating input data based on the extended MAC address and at least one transform parameter;
- generating output data by applying a preset transform function to the input data;
- generating a short MAC address based on the output data;
- selecting one of the short MAC address and the extended MAC address as a MAC address of the first UWB device;
- and
- performing UWB communication with a second UWB device, using the selected MAC address,
- wherein the second UWB device operates as a controller defining and controlling a control message for UWB ranging,
- wherein the first UWB device operates as a controlee using information included in the control message, and
- wherein the at least one transform parameter includes at least one of a session identifier (ID) identifying a UWB session, a scrambled timestamp sequence (STS) index value used to generate an STS, or a vendor specific value used to generate the STS.
A method of a second ultra-wideband (UWB) device, comprising:
- generating an extended medium access control (MAC) address of a first UWB device;
- transmitting the extended MAC address to the first UWB device through a first out-of-band (OOB) message;
- and
- performing UWB communication with the first UWB device, using one of the extended MAC address and a short MAC address of the first UWB device as a MAC address of the first UWB device,
- wherein the second UWB device operates as a controller defining and controlling a control message for UWB ranging,
- wherein the first UWB device operates as a controlee using information included in the control message,
- wherein the short MAC address is generated by generating input data based on the extended MAC address and at least one transform parameter, generating output data by applying a preset transform function to the input data, and generating the short MAC address based on the output data, and
- wherein the at least one transform parameter includes at least one of a session identifier (ID) identifying a UWB session, a scrambled timestamp sequence (STS) index value used to generate an STS, or a vendor specific value used to generate the STS.
A first ultra-wide band (UWB) device for performing secure ranging, the first UWB device comprising:
- a transceiver;
- and
- a controller operationally connected with the transceiver, the controller being configured to:
- identify an extended medium access control (MAC) address of the first UWB device;
- generate input data based on the extended MAC address and at least one transform parameter;
- generate output data by applying a preset transform function to the input data;
- generate a short MAC address based on the output data;
- select one of the short MAC address and the extended MAC address as a MAC address of the first UWB device;
- and
- perform UWB communication with a second UWB device, using the selected MAC address,
- wherein the second UWB device operates as a controller defining and controlling a control message for UWB ranging,
- wherein the first UWB device operates as a controlee using information included in the control message, and
- wherein the at least one transform parameter includes at least one of a session identifier (ID) identifying a UWB session, a scrambled timestamp sequence (STS) index value used to generate an STS, or a vendor specific value used to generate the STS.
A second ultra-wide band (UWB) device for performing secure ranging, the second UWB device comprising:
- a transceiver;
- and
- a controller operationally connected with the transceiver, the controller being configured to:
- generate an extended medium access control (MAC) address of a first UWB device;
- transmit the extended MAC address to the first UWB device through a first out-of-band (OOB) message;
- and
- perform UWB communication with the first UWB device, using one of the extended MAC address and a short MAC address of the first UWB device as a MAC address of the first UWB device,
- wherein the second UWB device operates as a controller defining and controlling a control message for UWB ranging,
- wherein the first UWB device operates as a controlee using information included in the control message,
- wherein the short MAC address is generated by generating input data based on the extended MAC address and at least one transform parameter, generating output data by applying a preset transform function to the input data, and generating the short MAC address based on the output data, and
- wherein the at least one transform parameter includes at least one of a session identifier (ID) identifying a UWB session, a scrambled timestamp sequence (STS) index value used to generate an STS, or a vendor specific value used to generate the STS.
