Abstract: The present invention relates to a method for positioning multiple user equipments (UEs) by a base station in a wireless communication system supporting full-duplex communication and an apparatus therefor. More specifically, the present invention comprises: setting a unit distance on the basis of the magnitude of inter-device interference (IDI) with respect to a first UE; and establishing multiple boundaries around each of the multiple UEs and the base station according to relative distances on the basis of the unit distance and checking whether the boundaries overlap each other. Here, the relative distances indicate with respect to the multiple UEs, measured on the basis of the magnitude of inter-device interference (IDI).
