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: The present invention relates to techniques for a sensor network, machine-to-machine (M2M) communication, machine-type communication (MTC) and internet of things (IoT). The present invention may be applied to said technique-based intelligent services (such as smart home, smart building, smart city, smart or connected car, health care, digital education, retail business, and services associated with security and safety). A transmission apparatus of a wireless communication system according to an embodiment of the present invention comprises: a transmission unit for transmitting a compressed beacon frame by means of a plurality of transmission beams; a receiving unit for receiving information for the optimal transmission beam from among the plurality of transmission beams; and a control unit for controlling beamforming by means of a beam received from a terminal, wherein the data and header are compressed into a single frame in the compressed beacon frame.
