Abstract: A method and apparatus for performing a scheduling request for transmitting uplink data in a wireless communication system are provided. Specifically, a terminal receives allocation information for a first SR resource that is semi-statically allocated from a base station. The terminal receives allocation information for a second SR resource dynamically allocated from the base station. The second SR resource is additionally allocated in addition to the first SR resource for a buffer status report (BSR). At this time, the allocation information for the first SR resource comprises: mapping information between the first and second SR resources and buffer size information. The terminal transmits an SR to the base station through the first SR resource or the second SR resource.

Abstract: The document relates to a method for performing communication using multiple transmission time interval (TTI) structures in a wireless communication system. In this method, a terminal transmits and receives a signal through a resource region in which a first subframe corresponding to a TTI (short TTI) of a first length and a second subframe corresponding to a TTI (short TTI) of a second length longer than the first length are multiplexed in a frequency divisional multiplexing (FDM) manner, and when a second link direction of a signal transmitted through the second subframe in a specific time interval is different from a first link direction of a signal transmitted through the first subframe, the specific time interval of the second subframe is not used for signal transmission in the second link direction.
