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). A method and system for selecting a beamforming configuration for a first antenna array for communication with a second antenna array are provided. The first array is configurable according to a first plurality of configurations and is associated with a first terminal. The method and system are configured to identify a first subset of beamforming configurations from the first plurality of beamforming configurations wherein each of the first plurality of beamforming configurations is associated with a data value, and the identification comprises using information associated with the location of any one or more of the first or second arrays. The method and system are configured to select a first set of one or more data values associated with the one or more beamforming configurations in the first subset and select a beam forming configuration associated with at least one data value from the first set of data values.
