    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 Long Term Evolution (LTE). An apparatus and a method for searching neighboring cells in a wireless communication system are provided. The method includes receiving, from adjacent base stations, a part of a first set of reference signals that are beamformed using different transmission beams arranged in a first order, the part of the first set of the reference signals being received during a first measurement interval in a first time interval, and receiving, from the adjacent base stations, a part of a second set of the reference signals that are beamformed using different transmission beams arranged in a second order, which is different from the first order, the part of the second set of the reference signals being received during a second measurement interval in a second time interval.

    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 BE precoder is determined for the determined analog BE direction. Digital BF precoding is performed using the digital BE 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.
