Abstract  Abstract

The present invention relates to a wireless access system supporting millimeter wave (mmWave), and provides methods for performing quick fallback to avoid link disconnection and devices supporting it. A method for performing quick fallback of a terminal in a wireless access system supporting millimeter wave (mmWave) according to an embodiment of the present invention includes establishing a radio resource control (RRC) connection with an mmWave base station and a legacy base station, Receiving the downlink data to be transmitted, receiving resource related information related to a resource to be allocated for fast fallback from the legacy base station, and determining whether a non-light of sight (NLoS) transition occurs in the mmWave link with the mmWave base station And transmitting a fallback request message to perform a fast fallback to the legacy base station when the NLoS transition occurs.
