Abstract: A pre-5th-generation (5G) or 5G communication system for supporting higher data rates beyond 4th-generation (4G) communication system, such as a long term evolution (LTE), is provided. A method for performing a beamforming operation in a communication system supporting a frequency division-multiple input multiple output (FD-MIMO) scheme is provided. The method includes detecting a rough beam of a first dominant beam, detecting at least two codeword candidates based on the rough beam of the first dominant beam, and selecting one of the at least two codeword candidates as a final codeword.

Abstract: A method for manufacturing a semiconductor device can reduce congestion across wires while reducing a wire length. The method includes determining a first TSV candidate region in a first die and determining a second TSV candidate region in a second die parallel to the first die. The method also includes determining a first bound region. The first bound region includes a horizontal location of a first pin of the first die and a horizontal location of a second pin of the second die. The method additionally includes calculating an area from overlapped regions between the first bound region and each of the first TSV candidate region and the second TSV candidate region, and performing routing for connecting the first pin and the second pin to each other based on the calculated area.
