Abstract

A beam allocation method of a Base Station (BS) in a wireless communication system is provided. The method includes transmitting a reference signal to a Mobile Station (MS) using a plurality of downlink transmit (Tx) beams receiving information of a plurality of candidate downlink Tx beams determined by the MS in response to the received reference signal selecting at least one downlink Tx beam from the plurality of candidate downlink Tx beams according to a predefined rule generating control information for burst transmission comprising the selected at least one downlink Tx beam information transmitting the control information to the MS using the selected at least one downlink Tx beam and transmitting a data burst based on Tx beam information included in the control information.
