Abstract: A method and a device for direct communication in a communication system supporting multiple links are disclosed. A method of an AP MLD comprises the steps of: transmitting a trigger frame in multiple links including a first link and a second link; receiving a response frame for the trigger frame from a first STA associated with an STA MLD in the first link; receiving a first data frame from a third STA in the second link; and when a subject to receive the first data frame is a second STA associated with the STA MLD, transmitting a second data frame generated on the basis of the first data frame, to the first STA in the first link.
