Abstract: The present invention relates to a wireless access system supporting millimeter waves (mmWave) and provides methods for performing fast fallback so as to avoid link disconnections and devices for supporting same. The method whereby a legacy base station supports the fast fallback of a mmWave terminal in a wireless access system supporting millimeter waves (mmWave), according to one embodiment of the present invention, may comprise the steps of: receiving, from the mmWave terminal, a first fallback request message for requesting fast fallback; operating a fallback timer for determining whether or not to perform fallback after receiving the first fallback request message; and determining whether or not a second fallback request message for requesting fast fallback has been received from a mmWave base station within the fallback timer.

Abstract: A method for transmitting uplink (UL) data requiring low latency in a wireless communication system is disclosed. The method performed by a user equipment (UE) includes receiving a first control message for informing a basic Contention-based PUSCH (Physical Uplink Shared Channel) Zone (CP zone) allocated to each subframe from an enhanced Node B (eNB), receiving a second control message for informing changes in a CP zone allocated to a specific subframe from the eNB, and transmitting UL data to the eNB through a CPRB (Contention PUSCH Resource Block) of the changed CP zone based on the received second control message. The first control message includes basic CP zone resource information indicating resource information of the basic CP zone, and the second control message includes changed CP zone resource information indicating resource information of the changed CP zone.
