Abstract
A method of a receiving a downlink signal from a base station including a two-dimensional (2D) antenna array composed of a plurality of antenna elements in a wireless communication system is disclosed. The method includes receiving a reference signal allocated to at least one column-direction antenna array of the 2D antenna array, receiving information about a semi-static beam candidate set composed of at least one semi-static beam applicable to the at least one column-direction antenna array, and measuring an average channel state for semi-static beamforming using the received reference signal and the information about the semi-static candidate set. The 2D antenna array is virtualized to one-dimensional (1D) antenna array supporting dynamic beamforming by applying at least one semi-static beam in the semi-static beam candidate set to the column-direction antenna array.
