Method and device for allocating payload using uwb communication

A method of a second ultra-wide band (UWB) device in a wireless communication system, the method comprising:

• receiving, from a first UWB device, a control message including a ranging device management list (RDML) for UWB ranging;
• receiving, from the first UWB device, a ranging initiation message based on the control message;
• and
• transmitting, to the first UWB device, a ranging response message corresponding to the ranging initiation message and data piggybacked on the ranging response message,
• wherein the data includes a header and a payload, and
• wherein the header includes a length of the data and an address of the second UWB device.

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

• a transceiver;
• and
• a processor coupled with the transceiver and configured to:
• control to transmit a control message including a ranging device management list (RDML) for UWB ranging;
• control to transmit a ranging initiation message based on the control message;
• and
• receive, from a second UWB device, a ranging response message corresponding to the ranging initiation message and data piggybacked on the ranging response message,
• wherein the data includes a header and a payload, and
• wherein the header includes a length of the data and an address of the second UWB device.
