Abstract:Considering resource allocation in Device-to-Device (D2D) communications,a joint link sharing and power allocation algorithm is proposed.On the premise of guaranteeing the Quality of Service (QoS) requirements of cellular users in the system,a candidate set of communication links composed of cellular users is generated for the D2D users by using the channel state information of the system.The optimal power allocation strategy for D2D users is obtained by using the convex optimization method in the candidate set of communication links.Finally,the Kuhn-Munkres (KM) algorithm is used to solve the maximum weight bipartite matching (MWBM) problem to find an optimal cellular user partner for each D2D pair to share the resources.Simulation results show that the proposed algorithm can significantly improve the throughput of the communication system and can select the optimal resource allocation strategy for D2D users.
