Ultrawide band device for transmitting and receiving plurality of packets and operation method thereof

A method for operating a second ultra-wideband (UWB) device, the method comprising:

• receiving, from a first UWB device through a UWB or a narrow band (NB), a ranging control message for UWB multiple transmissions in a first slot within a ranging round;
• receiving, from the first UWB device through the UWB or the NB, a triggering packet for triggering the UWB multiple transmissions in a second slot within the ranging round;
• and
• transmitting, through the UWB, a first packet in a third slot within the ranging round, based on the ranging control message,
• wherein the third slot within the ranging round is used for a second packed to be transmitted by a third UWB device, based on the ranging control message.

A first ultra-wideband (UWB) device comprising:

• a transceiver;
• and
• a controller coupled with the transceiver and configured to control the transceiver,
• wherein the UWB device is configured to:
• transmit a ranging control message for UWB multiple transmissions through a UWB or a narrow band (NB) in a first slot within a ranging round,
• transmit a triggering packet for triggering the UWB multiple transmissions through the UWB or the NB in a second slot within the ranging round,
• receive a first packet transmitted by a second UWB device in a third slot within the ranging round, based on the ranging control message, through the UWB, and
• receive a second packet transmitted by a third UWB device in the third slot within the ranging round, based on the ranging control message, through the UWB.
