Abstract: Provided is a method for receiving, by a user equipment (UE), a feedback from a base station in a wireless communication system supporting narrowband (NB)-internet of things (IoT). Specifically, the UE receives, from the base station, a preconfigured uplink (UL) resource (PUR) configuration via RRC signalling, transmits, to the base station, uplink data on the PUR when the UE is in an idle mode, and receive, from the base station, the feedback for the uplink data. The feedback is configured to be received on an NPDCCH after a specific time has passed from the PUR transmission.
