    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: 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). A method for operating a terminal in a wireless communication system comprises transmitting, to a base station, at least one reference signal through at least one first transmission beam and if ACK information for the at least one reference signal is received from the base station, transmitting, to the base station, the at least one reference signal through at least one second transmission beam. A width of the at least one second transmission beam is greater than a width of the at least one first transmission beam.

    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.

    Abstract: A method and an apparatus for transmitting and receiving an uplink signal by a mobile terminal in a wireless communication system are provided. The first mobile terminal includes a receiver configured to receive, from a base station, a power control variable determined based on an interference value for a first receive beam used in order to receive an uplink signal of the first mobile terminal from among a plurality of receive beams of the base station, to receive, from the base station, neighboring receive beam allocation data indicating whether any of the receive beams in the plurality of receive beams, different from the first receive beam, is being used for uplink signal reception, to determine an uplink transmit power value based on the received power control variable and neighboring receive beam allocation data, and to transmit an uplink signal to the base station by using the determined uplink transmit power value.
