1. An electronic device comprising:
an ultra-wide band (UWB) communication module;
a memory; and
a processor operably connected to the UWB communication module and the memory, wherein the processor is configured to:
receive, through the UWB communication module, a first message from a first external electronic device at a first time slot;
store, in the memory, the first message and a receiving time of the first message;
receive, through the UWB communication module, a second message from a second external electronic device at a second time slot;
store, in the memory, the second message and a receiving time of the second message;
identify a time schedule information for transmitting a third message to the first external electronic device and the second external electronic device, the time schedule information including a transmitting time of the third message;
obtain first time information regarding a period of time between the receiving time of the first message and the transmitting time of the third message and second time information regarding a period of time between the receiving time of the second message and the transmitting time of the third message; and
transmit, through the UWB communication module, the third message including the first time information and the second time information to the first external electronic device and the second external electronic device at a third time slot.
