Abstract: A method for controlling, by a user equipment (UE), a transmit power in a narrowband (NB) wireless communication system is disclosed. The method includes receiving, from a base station, a preconfigured uplink (UL) resource (PUR) configuration, transmitting, to the base station, uplink data on the PUR, and receiving, from the base station, feedback information for the uplink data. A transmit power of the uplink data is controlled based on a number of receptions of the feedback information.
