Abstract: A method and an electronic device for ranging are provided. An ultra-wideband (UWB) signal is received from an external device through a first antenna. A communication state between the external device and the electronic device is identified using information about communication quality included in the UWB signal. A signal received through a second antenna is identified by decoding the received signal based on the identified communication state. A distance between the electronic device and the external device is determined based on whether the received signal is a low frequency (LF) signal.

Abstract: Provided is a method of operating a controller, a method of operating a controlee, a controller, and a controlee. The method of operating a controller that performs a ranging with a controlee using ultra wideband (UWB) communication in a wireless communication system, the method including: transmitting, to the controlee, a first ranging control message (RCM) comprising information of a first ranging interval for a second RCM; changing a ranging interval for the second RCM from the first ranging interval to a second ranging interval; transmitting, to the controlee, an interval update message for the second RCM comprising information for the changed ranging interval based on the first ranging interval; and transmitting, to the controlee, the second RCM based on the changed ranging interval.
