Abstract: Provided is a secure ranging method capable of blocking access of a malicious user by preventing an attack by the malicious user when ranging is performed using an ultra-wideband (UWB). Also, provided is a method of increasing accuracy of ranging. A method of operating an electronic device for performing ranging by using a UWB in a wireless communication system includes: transmitting and receiving at least one frame for ranging, to and from at least one other electronic device; obtaining a first ranging value and a second ranging value, based on the at least one frame; and performing integrity checking, based on a result of comparing the first ranging value with the second ranging value.

Abstract: Provided is a method, performed by an electronic device, of performing secure ranging with a target device. The method of performing secure ranging may include receiving a connection message for communication with the target device using a first communication method through a first communicator, transmitting, by a first applet in a secure element of the electronic device, a ranging session key for the target device to a second applet in the secure element, the ranging session key being stored in the first applet, receiving a ranging session request from the target device, based on the ranging session request, obtaining, by a second communicator, the ranging session key for the target device from the second applet, and by using the ranging session key, performing secure ranging using a second communication method with the target device through the second communicator.

Abstract: The present disclosure provides a method for controlling a non-UWB device by using a UWB. A method of a first UWB device, of the present disclosure, may comprise the steps of: identifying the location of a non-UWB device based on the location of a second UWB device on the basis of the UWB ranging between the first UWB device and the second UWB device; and recognizing the non-UWB device on the basis of the pointing direction of the first UWB device and the identified location of the non-UWB device.

Abstract: Disclosed is a method for performing downlink time difference of arrival (DL-TDoA) by an ultra-wide band (UWB) device that includes selecting at least one active ranging round from a ranging block based on at least one of location information or motion information about the UWB device, transferring, to a UWB sub system, a command including information about the at least one active ranging round, and performing a DL-TDoA operation based on the information about the at least one active ranging round.
