Classification: CPC H | IPC H

Claim 0:
1. A method for receiving a channel state information-reference signal (CSI-RS) by a user equipment (UE) in a wireless communication system, the method comprising:
receiving, from a base station, CSI-RS configuration information about a CSI-RS configuration to which the CSI-RS is mapped; and
receiving the CSI-RS transmitted from the base station through plurality of antenna ports based on the received CSI-RS configuration information,
wherein, when the CSI-RS configuration is a 32-port CSI-RS configuration into which four 8-port CSI-RS configurations are aggregated, a code division multiplexed (CDM)-8 pattern, in which the number of orthogonal weight vectors is 8, is applied to the 32-port CSI-RS configuration,
wherein the CDM-8 pattern is applied to a plurality of resource element (RE) pairs selected for each of the four 8-port CSI-RS configurations,
wherein all or some of the plurality of RE pairs are not contiguous in at least one of a time domain and a frequency domain.
