Abstract: The present invention relates to a method and an apparatus for generating a signal for low latency in a wireless communication system. The method, according to one embodiment of the present invention, for a communication device generating a situation-reporting signal for low latency and transmitting the signal to a base station in a wireless communication system comprises the steps of: generating the situation-reporting signal on the basis of a pre-set, specific situation recognized by the communication device; and transmitting the generated situation-reporting signal to the base station, wherein the situation-reporting signal may be generated so as to have a subcarrier spacing which is a pre-set number of times larger than a subcarrier spacing of a legacy communication system, the pre-set number being an integer.
