Abstract: A method for operating a receiving end in a wireless communication system includes receiving subset information on analog beams of a transmitting end, from a transmitting end, and determining a combination of transmit beams to be used for data signal transmission to the receiving end, on the basis of the subset information, wherein the subset information indicates at least one subset into which the analog beams are classified, and each analog beam of the at least one subset has a correlation equal to or less than a threshold, with one another. An apparatus for a receiving end includes a communication unit configured to receive subset information on analog beams of a transmitting end, from the transmitting end, and a controller configured to determine a combination of transmit beams to be used for data signal transmission to the receiving end, on the basis of the subset information.
