Abstract

The present invention relates to a wireless communication system, and more particularly to a method and device for allocating a positioning reference signal (PRS) or channel state information-reference signal (CSI-RS), and a device and method for receiving a reference signal using same in the wireless communication system. For allocating a first reference signal between the PRS and CSI-RS, which is a target to be allocated, to a time-frequency resource space and transmitting the first reference signal, a method of the present invention comprises the steps of: checking configuration information on a second reference signal for one or more cells; and determining configuration information (transmission subframe or allocation resource element) on the first reference signal such that the configuration information overlaps, as little as possible, a transmission subframe or allocation resource element configured for transmission of the second reference signal. For allocating the PRS for position measurement and the CSI-RS for channel estimation to a resource space together and transmitting the PRS and CSI-RS, resources are allocated so as to overlap on a subframe or RE basis as little as possible, thereby maximally preventing degradation of position measurement performance and channel estimation performance of a terminal.
