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.
Abstract:
A method in which a User Equipment (UE) measures a downlink signal in a wireless communication system is disclosed. The method includes receiving information about a Beam Direction Pattern (BDP) of the downlink signal and measuring the downlink signal based on the information about the BDP. The information about the BDP includes an index of a subframe in which the downlink signal is to be transmitted using a specific BDP and includes an identifier (ID) of the specific BDP. The BDP of the downlink signal is switched according to the subframe index based on the information about the BDP.
