1. A method of performing a measurement in a wireless communication system, the method performed by a user equipment (UE) and comprising:
- receiving, from a base station (BS), a cell-specific reference signal (CRS) configuration including information related to whether or not two antenna ports are used for a CRS;
receiving, from the BS, a discovery signal received via a number of antenna ports, the number of antenna ports used for receiving the discovery signal derived from the information included in the CRS configuration; and
measuring at least a reference signal receive power (RSRP) or a reference signal received quality (RSRQ) based on the discovery signal,wherein, when the information included in the CRS configuration informs that the two antenna ports are used for the CRS, the discovery signal comprises a CRS for discovery on the two antenna ports.

Abstract
A method for performing a measurement in a wireless communication system and an apparatus for the same are disclosed. Particularly, a method by which a terminal performs a measurement in a wireless communication system comprises the steps of: receiving, by the terminal, a discovery signal; and measuring, by the terminal, reference signal received power (RSRP) and/or reference signal received quality (RSRQ) on the basis of the discovery signal, wherein the number of antenna ports of a cell-specific reference signal (CRS) cannot be applied to the discovery signal-based measurement.

11. A user equipment (UE) for performing measurement in a wireless communication system, the UE comprising:
-
a radio frequency (RF) unit configured to transmit and receive a wireless signal; and a processor configured to; control the RF unit to receive, from a base station (BS), a cell-specific reference signal (CRS) configuration including information related to whether two antenna ports are used for a CRS; control the RF unit to receive the discovery signal from the BS via a number of antenna ports, the number of antenna ports used for receiving the discovery signal derived from the information included in the CRS configuration; and measure at least a reference signal receive power (RSRP) or a reference signal received quality (RSRQ) based on the discovery signal, wherein, when the information included in the CRS configuration informs that the two antenna ports are used for the CRS, the discovery signal comprises a CRS for discovery on the two antenna ports. - View Dependent Claims (12, 13, 14)
