    • The present invention relates to a wireless access system supporting a millimeter wave (mmWave), and provides methods for performing a fast fallback in order to avoid a link disconnection and devices supporting the same. As an embodiment of the present invention, a method for performing a fast fallback by a terminal in a wireless access system supporting a millimeter wave (mmWave) may comprise the steps of: establishing radio resource control (RRC) connections with a mmWave base station and a legacy base station, respectively; receiving downlink data transmitted from the mmWave base station; receiving, from the legacy base station, resource-related information associated with a resource to be allocated for a fast fallback; detecting whether a non-light of sight (NLoS) transition occurs in a mmWave link with the mmWave base station; and when the NLoS transition occurs, transmitting a fallback request message to the legacy base station in order to perform the fast fallback.
    • 支持毫米波(mmWave)的无线接入系统技术领域本发明涉及一种支持毫米波(mmWave)的无线接入系统,并且提供了用于执行快速回退以避免链路断开的方法以及支持该方法的设备。 作为本发明的一个实施例,一种用于在支持毫米波(mmWave)的无线接入系统中由终端执行快速回退的方法可以包括以下步骤:与毫米波基站建立无线电资源控制(RRC)连接,以及 传统基站; 接收从毫米波基站发送的下行链路数据; 从传统基站接收与将被分配用于快速回退的资源相关联的资源相关信息; 检测在毫米波基站的毫米波链路中是否发生非瞄准光(NLoS)跃迁; 并且当NLoS转换发生时,将回退请求消息发送到传统基站以执行快速回退。
