Abstract: Since each DU (Devcie-to-Device user) perceives different channel gains when sharing resource with different shared cellular user (CU),it is important to associate a DU with the right CU for the improvement of spectrum efficiency.Despite its importance,the resource optimization in hybrid Device-to-Device (D2D) cellular networks has been not solved perfectly due to the non-convex nature.This paper proposed a hybrid network resource optimization method (hnRoM) based on the linear programming and bipartite matching.The hnRoM algorithm first decomposes the resource optimization problem into the DU-CU assignment optimization subproblem and the time resource allocation optimization subproblem.The optimal solution of the time resource allocation optimization subproblem is obtained by linear programming.By utilizing the obtained optimal solution,the optimal DU-CU assignment is achieved based on the bipartite graph model.Finally,the simulation results show that all DUs can be served for the maximal system throughput while satis-fying the minimum transmission rate requirements of all users.
