transmit, through the UWB to the second electronic device via the at least one transceiver, a ranging start message based on the first ranging control message; and

receive, through the UWB from the second electronic device via the at least one transceiver, a ranging response message based on the first ranging control message,

wherein each of the first ranging control message and the second ranging control message comprises:

information related to a cast mode indicating that ranging following a corresponding ranging control message is a unicast mode, or a multicast mode; and

information related to a ranging operation mode indicating that the ranging following the corresponding ranging control message is a single-sided two-way ranging (SS-TWR) mode or a double-sided two-way (DS-TWR) mode.

10. The first electronic device of claim 9 , wherein the first ranging control message further comprises:

information related to a slot length; and

information related to a round length.

11. The first electronic device of claim 9 , wherein the at least one processor is further configured to execute the program to, when the cast mode is the broadcast mode and the ranging operation mode is the SS-TWR mode, receive via the transceiver, reply time information about a time interval from a time point when the second electronic device receives the ranging start message from the first electronic device to a time point when the second electronic device transmits the ranging response message to the first electronic device.

12. The first electronic device of claim 9 , wherein, when the ranging operation mode is the SS-TWR mode, the ranging response message comprises:

information related to a request to transmit a TX-to-RX roundtrip time; and

information related to a request to transmit a Ranging Result.
