    Abstract: An apparatus and a method for performing a beamforming operation in an access point (AP) in a millimeter Wave (mmWave) communication system are provided. The method includes transmitting a directional reference signal (RS) in an RS transmission (Tx) interval, and transmitting a training signal in an interval different from an interval during which the directional RS is transmitted in the RS Tx interval based on beamforming patterns supported in the AP, wherein a length of the training signal is shorter than a length of the directional RS. The apparatus and the method relate 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 a long term evolution (LTE).

    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 relates to a method and an apparatus in a communication system. A method of a network node in the communication system comprises the steps of: measuring at least one factor value indicating channel link performance of a channel link between the network node and another network node; identifying a beamforming training scheme based on the at least one factor value; and performing beamforming training with the another network node by means of the selected beamforming training method, thereby finding an optimal beam for maintaining services through the most efficient method according to a channel state and minimizing the time consumed for beamforming training.
