Claim 0:
1. A base station to transmit Channel State Information-Reference Signal (CSI-RS) information, comprising:
a processor configured to generate CSI-RS information including a CSI-RS zero power configuration associated with a cycle and an offset of zero power transmission subframes and a CSI-RS zero power configuration list having an n-bit bitmap, the n being an integer among 12 to 28, and each bit of the n-bit bitmap indicating whether to apply zero power transmission for resource elements corresponding to a CSI-RS pattern for a specific number of antenna ports; and
a transmitter configured to transmit the CSI-RS information to a user equipment,
wherein the processor is configured to map data to the resource elements using the CSI-RS information, and
wherein the transmitter is configured to transmit a signal including the mapped data to the user equipment.
