Abstract: Disclosed is a method for transmitting and receiving data between a user equipment (UE) and a base station in a narrowband wireless communication system. Specifically, the method includes transmitting, to the UE, a preconfigured uplink (UL) resource (PUR) configuration via RRC signalling, receiving, from the UE, uplink data on the PUR when the UE is in an idle mode, and transmitting, to the UE, a feedback for the uplink data, wherein the feedback is configured to be transmitted on an NPDCCH after a specific time has passed from the PUR reception.

Abstract: The present invention discloses a method for transmitting/receiving data in a wireless communication system supporting NB-IoT and a device for the method. More specifically, the method comprises receiving a first NPDCCH through a first search space; receiving a first NPDSCH carrying an SC-MCCH; receiving a second NPDCCH through a second search space; receiving a second NPDSCH carrying an SC-MTCH; and when a time period configured for at least one of a third NPDCCH or a third NPDSCH overlaps at least one of the first search space, a time period configured for the first NPDSCH, the second search space, or a time period configured for the second NPDSCH, preferentially receiving at least one of the third NPDSSCH or the third NPDSCH, wherein the third NPDCCH and the third NPDSCH are channels configured for either paging or random access.
