A Heuristic D2D Communication Mode Selection Algorithm

摘要：

　　In a D2D(Device-to-Device)communication system,mode selection is studied by taking SINR of D2D users as the baseline.Firstly,in this paper,mode selection is transformed into an optimization problem taking maximization of system throughput as an object.A heuristic algorithm is proposed in order to reduce computation complexity and the problem is decomposed into two subproblems of mode selection and resource allocation.Assuming that cell channel state information is available,the conditions of shared mode,dedicated mode and cellular mode used by D2D users are obtained respectively and a resource allocation strategy is designed for dedicated mode.Simulation result shows that the algorithm can improve transmission rate of D2D users effectively.
