1. An electronic device, comprising:
a wireless communication module configured to support ultra-wide band (UWB) communication; and
at least one processor operatively connected with the wireless communication module, wherein the at least one processor is configured to:
set the wireless communication module to a wake-up state;
when a given number of first ranging response messages (RRMs) are received from second external electronic devices after receiving a first ranging initiation message (RIM) from a first external electronic device in a RIM slot of a first ranging round, set the wireless communication module to a sleep state after receiving a first ranging final message (RFM) from the first external electronic device in a RFM slot of the first ranging round until a RIM slot of a second ranging round is reached after the first ranging round;
set the wireless communication module to the wake-up state in the RIM slot in the second ranging round; and
set the wireless communication module to the sleep state if a second RIM is not received from a third external electronic device in the RIM slot in the second ranging round.
