Abstract: The present specification relates to a method for transmitting uplink data (UL data) in a wireless communication system for supporting a low latency service, and the method executed by a first terminal is characterized by including the steps of: transmitting, to a base station, an urgent signal (US) for informing occurrence of an event related to an urgent situation; receiving, from the base station, a response to the urgent signal through two physical HARQ indication channel (PHICH) resources; and transmitting, to the base station, urgent data including detailed information related to the event that has occurred based on the received response. Each of the PHICH resources is determined by a physical resource block (PRB) index of a resource through which the urgent signal is transmitted.
