Abstract:
An apparatus and method for selecting the best beam in a wireless communication system are provided. An operation of a Base Station (BS) includes repeatedly transmitting reference signals beamformed with a first width, receiving a feedback signal indicating at least one preferred-beam having the first width from at least one terminal, determining a direction range within which reference signals beamformed with a second width are to be transmitted and a transmission pattern, based on the at least one preferred-beam having the first width, repeatedly transmitting the reference signals beamformed with the second width within the determined direction range according to the transmission pattern, and receiving a feedback signal indicating at least one preferred-beam having the second width from the at least one terminal.
