Abstract: An operating method of a communication device for providing a beamformed transmission signal to a plurality of terminals may include determining a target transmission vector based on an area restriction condition for each of the plurality of terminals, generating a beam selection matrix for selecting some of a plurality of antennas based on the target transmission vector and a beam selection condition, generating a precoding matrix based on the target transmission vector and the beam selection matrix, and generating a transmission signal based on the beam selection matrix and the precoding matrix.
