Claim:
1. A method for providing an interference recognition-based device to device (D2D) resource allocation in a cellular system, the method comprising: receiving information of a resource block of a least interference amount, the information being obtained by a D2D receiving terminal 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 a plurality of cellular terminals, the information being obtained from resource scheduling information which 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 of the cellular terminal, wherein the resource scheduling information is a scheduling information in which an allocation value of the resource block is dynamically changed per each time period, and the simultaneously allocating the frequency resource is performed by extracting only one resource block corresponding to a present time from in resource scheduling information corresponding to each cellular terminal, and generating fixed resource scheduling information configured of only the one resource block and simultaneously allocating the generated fixed resource scheduling information to the cellular terminal, the D2D receiving terminal, and the D2D transmitting terminal, and the D2D receiving terminal communicates with the D2D transmitting terminal by statically using a resource block equal to the resource block allocated to the cellular terminal per each time period.
