Abstract: A beamforming method is provided. The beamforming method includes determining different beams for pieces of user equipment based on channel information fed back from the pieces of user equipment, predicting beam qualities of the pieces of user equipment for the beams, determining whether the beam qualities satisfy Quality of Service (QoS) for the pieces of user equipment, generating a wide nulling beam by applying wide nulling to a second beam having a side lobe acting as interference against one first beam, when the beam quality of the first beam does not satisfy the QoS; predicting beam qualities for the beams including the wide nulling beam instead of the second beam, and simultaneously communicating with the user equipment through the beams including the wide nulling beam instead of the second beam, when the beam qualities for the beams including the wide nulling beam instead of the second beam satisfy the QoS.

Abstract: A method for adjusting a beam pattern in a beam pattern adjusting apparatus in a communication system supporting a Beam Division Multiple Access (BDMA) scheme is provided. The method includes determining whether a Voltage Standing Wave Ratio (VSWR) value for each antenna included in an antenna array included in the beam pattern adjusting apparatus is greater than or equal to a threshold VSWR value, if it is determined that an antenna of the antenna array has a VSWR value that is greater than or equal to the threshold VSWR, detecting whether each of the antenna elements is operable, and if it is determined that at least one of the antennas is inoperable, adjusting a beam pattern of at least one of the antennas that is operable.
