Abstract
An electronic device includes 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 c…
