Ultra-wideband device for transmitting/receiving multiple packets and method for operating same

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

• receiving, from a first UWB device, a ranging control message for UWB communication in a slot of control phase within a ranging round;
• and
• transmitting a first packet in a slot of a ranging phase within the ranging round, wherein the slot of the ranging phase within the ranging round is allocated based on the ranging control message,
• wherein a second packet is transmitted, by a third UWB, in the slot of the ranging phase within the ranging round.

A first ultra-wideband (UWB) device comprising:

• a transceiver;
• and
• a controller coupled with the transceiver and configured to control the transceiver to:
• transmit, in a slot of control phase within a ranging round, a ranging control message for UWB communication,
• receive, from a second UWB device, a first packet in a slot of a ranging phase within the ranging round, wherein the slot of the ranging phase within the ranging round is allocated based on the ranging control message, and
• receive, from a third UWB device, a second packet in the slot of the ranging phase within the ranging round.
