Abstract:
A method for transmitting a signal to a user equipment by a base station in a wireless communication system is disclosed. The method includes receiving information about a preferred beamforming vector in a first subframe from the user equipment, selecting a first random beamformer corresponding to the first subframe from a beamforming vector set for the first subframe, using the information about the preferred beamforming vector, transmitting a downlink signal to the user equipment in the first subframe using the first random beamformer, selecting a second random beamformer corresponding to a second subframe, using the first random beamformer, and transmitting a downlink signal to the user equipment in the second subframe using the second random beamformer.
