Abstract
An electronic device for supporting an ultra wide band (UWB) protocol transmits first data, including mode information indicating whether the electronic device supports a mode associated with control of a preamble and a preamble having a first length, to an external electronic device circuit, receives second data including mode information indicating whether the external electronic device supports the mode associated with the control of the preamble from the external electronic device, and controls a length of the preamble, based on the mode information included in the second data.
Claims15
An electronic device for supporting an ultra wide band (UWB), the electronic device comprising:
- at least one wireless communication circuit;
- and
- a processor operatively connected with the at least one wireless communication circuit,
- wherein the processor is configured to:
- transmit first data, including mode information indicating whether the electronic device supports a mode associated with control of a preamble and a preamble having a first length, to an external electronic device, via the at least one wireless communication circuit;
- receive second data including mode information indicating whether the external electronic device supports the mode associated with the control of the preamble from the external electronic device, via the at least one wireless communication circuit;
- measure a distance between the electronic device and the external electronic device using the preamble having the first length, when the external electronic device does not support the mode associated with the control of the preamble, based on the mode information included in the second data;
- and
- measure a distance between the electronic device and the external electronic device using a preamble having a second length different from the first length, when the external electronic device supports the mode associated with the control of the preamble, based on the mode information included in the second data.
An electronic device for supporting an ultra wide band (UWB), the electronic device comprising:
- at least one wireless communication circuit;
- and
- a processor operatively connected with the at least one wireless communication circuit,
- wherein the processor is configured to:
- receive first data, including mode information indicating whether an external electronic device supports a mode associated with control of a preamble and a preamble having a first length, from the external electronic device, via the at least one wireless communication circuit;
- transmit second data including mode information indicating whether the electronic device supports the mode associated with the control of the preamble to the external electronic device, via the at least one wireless communication circuit;
- measure a distance between the electronic device and the external electronic device using the preamble having the first length, when the electronic device does not support the mode associated with the control of the preamble, based on the mode information included in the second data;
- and
- measure a distance between the electronic device and the external electronic device using a preamble having a second length different from the first length, when the electronic device supports the mode associated with the control of the preamble, based on the mode information included in the second data.
A method of an electronic device for supporting a UWB protocol, the method comprising:
- transmitting first data, including mode information indicating whether the electronic device supports a mode associated with control of a preamble and a preamble having a first length, to an external electronic device;
- receiving second data including mode information indicating whether the external electronic device supports the mode associated with the control of the preamble from the external electronic device;
- and
- measuring a distance between the electronic device and the external electronic device using the preamble having the first length, when the external electronic device does not support the mode associated with the control of the preamble, based on the mode information included in the second data;
- or
- measuring a distance between the electronic device and the external electronic device using a preamble having a second length different from the first length, when the external electronic device supports the mode associated with the control of the preamble, based on the mode information included in the second data.
