Abstract
The relay and Device to device (D2D) technologies can be used to improve the Quality of Service (QoS) of a mobile user in the edge region of the cellular networks, To coordinate these two technologies, this paper considers a heterogeneous network containing the D2D-direct, D2D-non-direct and cellular communication mode. Furtherly, a system model taking throughput as optimization object is built to descript this network precisely. It is proved that the objective function and the constraints satisfy the requirements of convex function, and then a power allocation algorithm based on Lagrange Multiplier is proposed to find the optimal solver. Finally, we evaluate the performance of algorithm in terms of throughput and fairness by simulation.
