The present invention relates to a method and apparatus for transmitting and receiving data in a wireless communication system supporting a low latency service. According to the present invention, a terminal transmits a request message for requesting transmission of data to provide the low latency service in an idle state to a base station, and in response to the request message, receives a response message including resource information related to transmission and reception of low latency service data from the base station, thereby when additional data is generated for providing the low latency service for transmitting and receiving the low latency service data, the additional resources may be extended to transmit the additional data.
