Abstract: The present invention relates to 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), and subsequent systems. The present invention provides a method by which a mobile station (MS) operates a beam in a communication system supporting a hybrid multiple-input multiple-output (MIMO) mode, the method comprising the steps of: receiving, from a base station (BS), information related to the number of beams to be used, by the BS, for a beam training process; receiving, from the BS, a downlink reference signal (RS); performing a channel estimation process on the basis of the downlink RS; and transmitting, to the BS, information related to the number of beams to be used by the MS, after performing the channel estimation process.
