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 for stably and flexibly performing ranging between a plurality of devices. According to an embodiment, a method of operating a first device for performing ranging by using ultra-wide band (UWB) may include: transmitting a first ranging control (RC) frame to a second device; performing ranging with the second device for a number of ranging rounds determined based on the first RC frame; changing at least one ranging parameter based on a change request received from the second device; and transmitting a second RC frame including the changed at least one ranging parameter.

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.
