Claim 13:
14. A UE receiving a CSI-RS in a wireless communication system, the UE comprising:
a Radio Frequency (RF) unit transmitting and receiving a radio signal; and
a processor controlling the RF unit, wherein the processor is configured
to receive, from a base station, CSI-RS configuration information about a CSI-RS configuration to which the CSI-RS is mapped; and
to receive 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 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.
