Abstract: The present disclosure relates to a 5th generation (5G) or pre-5G communication system for supporting higher data rates than a 4th generation (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.

Abstract: The present disclosure provides a method for performing a cellular communication in a device-to-device communication system, the method comprising the operations of: receiving scheduling to transmit an uplink signal through a specific resource of a discovery channel from a base station; generating uplink scheduling information notifying scheduling of the uplink signal; and transmitting the uplink scheduling information through at least one discovery resource of the discovery channel.
