    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 channel-related information feedback in a beamforming system, performed by a transmitter is provided. The method includes determining whether a receiver is to feed back gain information about an effective channel established between the transmitter and the receiver using channel-related information between the transmitter and the receiver, notifying the receiver of a feedback mode indicating whether the gain information is to be fed back, upon receipt of feedback information configured based on the feedback mode from the receiver, reconfiguring the effective channel based on the feedback information, and transmitting a signal on the reconfigured effective channel.

    Abstract: A method and apparatus for transmitting and receiving data in a communication system using beamforming are provided. The transmission method includes transmitting a control channel signal in a control channel region of a subframe using a first transmission beam of a base station. The transmission method also includes transmitting a data signal during a predetermined time period of a data region after the control channel region in the subframe using a second transmission beam determined based on the first transmission beam. The transmission method further includes transmitting a data signal in a remaining data region following the predetermined time period using a scheduled transmission beam.
