Abstract: A method for performing, by a UE, channel estimation in a wireless communication system includes: receiving, from an eNB, a control message including reference signal transmission pattern information representing a transmission pattern of a channel estimation reference signal (RS) transmitted through antenna ports; receiving the reference signal from the eNB on the basis of the received reference signal transmission pattern information; measuring a channel per antenna port of the eNB on the basis of the received reference signal; and feeding back channel state information related to the measured channel to the eNB.

Abstract: A method in which a User Equipment (UE) measures a downlink signal in a wireless communication system is disclosed. The method includes receiving information about a Beam Direction Pattern (BDP) of the downlink signal and measuring the downlink signal based on the information about the BDP. The information about the BDP includes an index of a subframe in which the downlink signal is to be transmitted using a specific BDP and includes an identifier (ID) of the specific BDP. The BDP of the downlink signal is switched according to the subframe index based on the information about the BDP.
