Abstract: The present invention relates to a wireless communication system. In detail, the present invention is a method for transmitting a scheduling request (SR) by a user equipment (UE) in a wireless communication system includes: receiving information on a resource for the scheduling request (SR) from a base station (BS); transmitting the scheduling request (SR) using the scheduling request (SR) resource transmitted over a control channel; and transmitting a first buffer status report (BSR) using uplink (UL) contention-based resources transmitted over a data channel. The UL contention-based resources are determined based on at least one of the resource for the scheduling request (SR) or an identifier (ID) of the UE.

Abstract: 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.

Abstract: The present specification provides a method for transmitting uplink data (UL data) requiring a low latency in a wireless communication system. The method performed by a terminal comprises: receiving control information related to a contention-based PUSCH zone from a base station; and transmitting uplink data to the base station on the basis of the received control information. The contention-based PUSCH zone is a resource area where uplink data of the terminal can be transmitted without allocation of a UL grant from the base station. Further, in order to distinguish between kinds of specific procedures performed by the terminal, the control information includes procedure-distinguishing information allocated for each kind of the specific procedures.
