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.

Description

technical field [0001] The present disclosure relates to beamforming in wireless communication systems. Background technique [0002] Today, data usage on wireless communication networks is growing exponentially. Accordingly, fourth-generation-super (4G) mobile communication technology has to support gigabyte-level communication even in an outdoor environment. The most prominent candidate technology for this is beamforming in the millimeter (mm) band. Compared with existing low-frequency bands, the millimeter-wave band has the advantage of being able to use broadband. However, the millimeter wave band also has the disadvantage of high channel attenuation. Beamforming is a technique capable of enhancing the strength of a signal in a specific direction by using multiple antennas. In the past, much research has been done on beamforming. In this way, beamforming can integrate multiple antennas in a small area as the length of the beam decreases at high frequency bands. Acc...
