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). The present invention provides a method and a device for cancelling inter-symbol interference in a wireless communication system. A method for a base station in a wireless communication system can comprises the steps of: transmitting multiple synchronous signals through multiple antennas to a terminal; receiving information on a propagation delay difference among the multiple synchronous signals from the terminal; and determining signal transmission timing for each of the multiple antennas on the basis of the information on the propagation delay difference.

Abstract: Disclosed is a 5th generation (5G) or pre-5G communication system to be provided for supporting a data transmission rate higher than that of a 4th generation (4G) communication system such as long term evolution (LTE). Examples of the present invention provide a beam selection and feedback device and method for minimizing complexity and overhead without performance deterioration in a beamforming MIMO wireless communication system. According to one example of the present invention, an apparatus of a receiving device in a wireless communication system comprises: a transceiver; and at least one processor, wherein the at least one processor is configured to: select at least one beam pair from among a plurality of transmission/reception beam pairs, and control the transceiver to transmit feedback information including indication information indicating whether the at least one beam pair is identical to a beam pair selected in a previous beamforming procedure.
