Abstract: An apparatus implements methods for random access in a wireless communication system using beamforming. A Subscriber Station (SS) measures a best downlink transmission beam among downlink transmission beams transmitted from a Base Station (BS), and transmits Random Access Channel (RACH) information, which includes indication information indicating the best downlink transmission beam, to the BS. The BS receives RACH information which includes indication information indicating a best downlink transmission beam among downlink transmission beams, and detects an RACH sequence and the best downlink transmission beam from the received RACH information.

Abstract: In a method of manufacturing a vertical semiconductor device, an insulation layer and a sacrificial layer are alternatively and repeatedly formed on a substrate to define a structure. The structure is etched to form a hole therethrough that exposes the substrate. A first semiconductor pattern is formed in a lower portion of the hole, and a blocking pattern, a charge storage pattern, a tunnel insulation pattern and a first channel pattern are formed on a sidewall of the hole. A second channel pattern is formed on the first channel pattern and the semiconductor pattern, and a second semiconductor pattern is formed on a portion of the second channel pattern on the semiconductor pattern to define an upper channel pattern including the second channel pattern and the second semiconductor pattern. The sacrificial layers are replaced with a plurality of gates, respectively, including a conductive material.

Abstract: The present disclosure relates 5G or pre-5G communication systems for supporting higher data transmission rate than those by LTE or other post-4G communication systems. According to the present disclosure, a method for operating a beamformed reference signal by a base station and terminal in a communication system, and the terminal, are provided. The method includes transmitting, to a terminal, control information indicating whether a first codebook is used for generating feedback information on a downlink reference signal. The first codebook is used if generating feedback information on the beamformed reference signal and is generated based on a number of antenna ports and a number of ranks.
