The present disclosure relates to a 5generation (5G) or pre-5G communication system for supporting higher data rates than a 4generation (4G) communication system such as long term evolution (LTE). A method for positioning a user equipment (UE) in a wireless communication system includes receiving a reference signal (RS) in a first bandwidth from each of a plurality of anchor nodes scheduled for RS transmission by a network server, determining whether a path overlap has occurred between the UE and the anchor nodes based on symmetry of channel impulse responses of the received RSs, transmitting a bandwidth extension request message to the network server, upon occurrence of a path overlap, receiving an RS in a second bandwidth larger than the first bandwidth from each of the plurality of anchor nodes in response to the transmission of the bandwidth extension request message, and generating information required to position the UE, using the RSs received in the second bandwidth.
