Abstract: The present specification relates to a method for allocating an uplink resource in a wireless communication system which supports low latency service. The method performed by a terminal comprises the steps of: transmitting, to a base station, a first message comprising an uplink resource request information element (UL resource request IE) to request uplink resource allocation; receiving, from a base station, a second message comprising a response to the UL resource request IE; receiving allocation of the uplink resource from the base station on the basis of the received response; and transmitting a third message to the base station by using the allocated uplink resource.

Abstract: A resource allocation method according to the present invention may comprise the steps of: allocating a signal of an external resource to a predetermined resource according to a preconfigured resource allocation frame structure by a first base station governing a first cell; allocating a signal of an internal resource to the resource according to the resource allocation frame structure by a second base station governing a second cell adjacent to the first cell; and frequency-hopping the signal of the internal resource by the second base station when the signal of the internal resource overlaps the signal of the external resource.
