The present invention relates to a method and an apparatus for transmitting and receiving data in a wireless communication system which supports a low latency service. According to the present invention, a method and an apparatus are provided, wherein a terminal transmits a request message to a base station for converting from an idle state to a connected state; receives, from the base station, a response message including the resource information associated with the transmission and reception of low latency service data, in response to the request message; and transmits and receives the low latency service data using an allocated resource. Thereafter, when additional data is generated, the terminal converts from an idle state to a connected state and transmits and receives the additional data.
