Abstract: A millimeter radio wave communication system. In a method for operating a base station (BS) in an analog/digital mixed BF system, an analog BF direction is determined. A digital BF precoder is determined for the determined analog BF direction. Digital BF precoding is performed using the digital BF precoder with respect to the determined analog BF direction. A DownLink Reference Signal (DL RS) is transmitted in the analog BF direction on which the digital BF precoding has been performed.

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 a long term evolution (LTE). An operating method of a base station (BS) in a communication system supporting a time division multiplexing (TDD) scheme is provided. The operating method includes transmitting, to a user equipment (UE) which uses a second radio access technology (RAT) different from a first RAT used by other BS different from the BS, information related to downlink (DL) and uplink (UL) timing of the other BS and margin information for synchronizing DL and UL timing of the first RAT with DL and UL timing of the second RAT, wherein the information related to the DL and UL timing of the other BS is received from the other BS, or predicted by the BS.

Abstract: A base station and terminal use methods of obtaining synchronization and system information in a wireless communication system. An operation of a base station includes generating a synchronization signal to be transmitted through a Synchronization Channel (SCH), generating a broadcast signal to be transmitted through a Broadcast Channel (BCH), and transmitting repetitively the SCH and the BCH by performing beamforming on the channels with different transmission beams.

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.
