摘要： A method for performing positioning for estimating position in a wireless communication system according to the present invention comprises transmitting, by a first UE, a positioning request message for performing the positioning to an eNB; transmitting, by the eNB, an anchor request message to neighboring UEs within a cell to find UEs which may become a second UE; receiving, the eNB, an anchor response message corresponding to a response to the anchor request message from at least one UE from among neighboring UEs within the cell; and determining, by the eNB, the second UE based on the received anchor response message.

摘要： A method for terminal clustering in a wireless communication system supporting D2D (Device-to-Device) communication and an apparatus supporting the method are disclosed. More specifically, a method for a user equipment (UE) to perform UE clustering in a wireless communication system supporting D2D communication comprises determining an initial preference value, determining an initial preference triplet by performing an AP (Affinity Propagation) method by increasing or decreasing the preference value, updating a preference triplet through a GSS (Golden Section Search) method based on the initial preference triplet, determining a final preference value for minimizing energy consumption of the entire UEs from the updated preference triplet; and determining a head UE and member UEs belonging to the head UE by performing the AP method by using the final preference value.
