6. A base station transmitting a feedback to a user equipment (UE) in a wireless communication system supporting narrowband (NB)-internet of things (IoT), the base station comprising:
a radio frequency (RF) module configured to transmit and receive a radio signal; and
a processor functionally connected to the RF module,
wherein the processor is configured to:
transmit, to the UE, a preconfigured uplink (UL) resource (PUR) configuration via RRC signalling;
when the UE is in an idle mode, receive, from the UE, uplink data on the PUR; and
transmit, 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.
