Abstract
Disclosed herein is an interference recognition-based D2D resource allocation method that uses a base station in a cellular system which includes the base station, a plurality of cellular terminals being in a cell that the base station covers, and a plurality of D2D terminals, including: receiving information of a resource block of a least interference amount that a D2D receiving terminal obtains through resource search and information of search time of the resource search from the D2D receiving terminal; obtaining information of a cellular terminal corresponding to the received resource block and the search time among the plurality of cellular terminals from resource scheduling information storing allocation information of the resource block depending on time per each cellular terminal; and simultaneously allocating frequency resource of the cellular terminal to the D2D receiving terminal and a D2D transmitting terminal by using resource scheduling information corresponding to the obtained cellular terminal.
