Abstract: Provided are an electronic device that performs ranging by using an ultra wide-band (UWB) communication scheme and an operation method of the electronic device. The operation method of the first electronic device includes transmitting a first ranging control message (RCM) comprising interval information to a second electronic device, determining a first time to transmit a second RCM based on the interval information, determining a first RCM timing window (RTW) based on the first time, transmitting the second RCM to the second electronic device in the first RTW, and transmitting a third RCM at a second time in a second RTW, based on a failure to receive a response message corresponding to the second RCM within a specific time period in the first RTW, wherein the second time is a random time point in the second RTW.
