Abstract: Disclosed is a method for setting a resource for Full Duplex Radio (FDR) Communication by a node in an FDR communication environment. According to the method, resources for the FDR communication can be selected in consideration of channel information of the nodes performing the FDR communication to obtain an improved achievable sum rate compared to Half Duplex Radio (HDR) communication schemes and to acquire diversity effects.

Abstract: Disclosed are a method for setting a resource, the method comprising the steps of: estimating channel information on each of a plurality of frequency resources available through CA by a base station in a FDR communication environment supporting the CA; transmitting the estimated channel information on the plurality of frequency resources to a counterpart node with which the base station is to perform a FDR communication; receiving channel information estimated by the counterpart node from the counterpart node; and selecting a frequency resource to be used for the FDR communication among the plurality of frequency resource by considering first channel information and second channel information together.
