Method for reporting channel state information for three dimensional beamforming in wireless communication system and apparatus for same

A method of receiving channel state information received from a user equipment by a base station for beamforming based on multiple antennas in a wireless communication system, the method comprising:

• transmitting information on a plurality of reference signal resources to the user equipment;
• and
• receiving channel state information containing information on a single preferred precoder to be commonly applied to the plurality of the reference signal resources and information on a single linking precoder for linking the plurality of the reference signal resources,
• wherein the multiple antennas are partitioned by partitions of a row unit or partitions of a column unit, and
• wherein each of the plurality of the reference signal resources correspond to a respective one of the partitions.

A user equipment configured to report channel state information reported to a base station for beamforming based on multiple antennas in a wireless communication system, the user equipment comprising:

• a transceiver;
• and
• a processor operatively connected to the transceiver and configured to:
• receive information on a plurality of reference signal resources from the base station;
• generate channel state information containing information on a single preferred precoder to be commonly applied to the plurality of the reference signal resources and information on a single linking precoder for linking the plurality of the reference signal resources;
• and
• report the channel state information to the base station,
• wherein the multiple antennas are partitioned by partitions of a row unit or partitions of a column unit, and
• wherein each of the plurality of the reference signal resources correspond to a respective one of the partitions.
