In this paper,we propose a low complexity spectrum resource allocation scheme cross the access points(APs)for the ultra dense networks(UDNs),in which all the APs are divided into several AP groups(APGs)and the total bandwidth is divided into several narrow band spectrum resources and each spectrum resource is allocated to APGs independently to decrease the interference among the ***,we investigate the joint spectrum and power allocation problem in UDNs to maximize the overall *** problem is formulated as a mixed-integer nonconvex optimization(MINCP)problem which is difficult to solve in *** joint optimization problem is decomposed into two subproblems in terms of the spectrum allocation and power allocation *** the spectrum allocation,we model it as a auction problem and a combinatorial auction approach is proposed to tackle *** addition,the DC programming method is adopted to optimize the power allocation *** decrease the signaling and computational overhead,we propose a distributed algorithm based on the Lagrangian dual *** results illustrate that the proposed algorithm can effectively improve the system throughput.
