Abstract: The present disclosure relates to a pre-5th-generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-generation (4G) communication system such as long term evolution (LTE). An apparatus and a method for performing beamforming by using an antenna array in a wireless communication system are provided. The apparatus includes at least one antenna array comprising antenna elements, a control unit configured to determine a number of beams to be formed through the at least one antenna array, and a communication unit configured to adjust paths associated with the antenna elements in order to configure as many antenna subsets as the number of the beams, and to form at least one beam through at least one antenna subset configured from the at least one antenna array.

Abstract: According to a method of an embodiment of the present disclosure, a method for correcting a beamforming pattern of a base station by an analysis server of a base station management network may comprise the steps of: when network management information is received from a first base station, identifying whether or not the network management information indicates the occurrence of a failure in an antenna element of the first base station; when the network management information indicates the occurrence of the failure in the antenna element of the first base station, analyzing an effect of a beamforming pattern of the first base station and analyzing a change in a cell coverage; on the basis of the result of the analysis, determining a first beamforming pattern for compensating for the failure in the antenna element; and transmitting, to the first base station, information about the first beamforming pattern by including the information in management control information.

Abstract: The disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). An operation method of a communication node in a wireless communication system is provided. The operation method includes generating a default beam pattern, based on a plurality of radio-frequency (RF) paths, by applying beamforming parameters, detecting a path failure associated with at least one RF path among the plurality of RF paths, identifying beamforming parameters based on the default beam pattern in response to the detection, and generating a recovered beam pattern associated with the default beam pattern based on the identified beamforming parameters, wherein the beamforming parameters for generating the recovered beam pattern are determined based on a shape of the default beam pattern.
