Abstract: The present invention relates to a 5th-generation (5G) or pre-5G communication system which is provided for supporting a higher data transfer rate after a 4th-generation (4G) communication system such as a long term evolution (LTE). The present invention provides a method for selecting, by an access point (AP), a beam in a communication system supporting a beamforming scheme, the method comprising: a step of transmitting information which indicates whether or not a duplicated beacon transmission interval (BTI) is operated; and a step of performing a transmit sector sweep (TXSS) process at least twice during the duplicated BTI.
