Abstract: There is provided a method of retransmission for a base station in a wireless communication system supporting beamforming. The method includes transmitting data at least once using a first beam; detecting a link disconnection within a retransmission request interval at the media access control (MAC) layer; determining, when a link disconnection is detected, a second beam; and retransmitting the data using the second beam.
