Abstract :
This paper addresses resource management problem in a heterogeneous network consisting of cellular users and multiple D2D pairs. The D2D users share spectrum with cellular uplink under the QoS constraint of cellular system and pay for the interference they cause. We propose a two-step resource management scheme to optimize D2D user´s transmitting power and the spectrum efficiency of the network. Firstly, the interference pricing and power allocation problem between a D2D pair and their allocated cellular uplink is formulated as a Stackelberg game. Then the Stackelberg equilibrium, i.e., the optimal interference price and transmitting power that maximize utilities of two players (the base station and the D2D transmitter), is obtained in close form. In the second step, with the close form expressions as important parameters, the situation is extended to multiple D2D pairs and a Hungarian algorithm based method is utilized to assign spectrum band to each D2D pair with the purpose of maximizing system spectrum efficiency. Simulation results demonstrate the advantageous performance of our scheme in network capacity and spectrum efficiency.
