Summary: | In order to enable the benefits of device-to-device (D2D) communications underlay cellular networks, two fundamental problems need to be addressed: 1) how to control the interference to guarantee the quality-of-service (QoS) of cellular user and 2) how to allocate transmit powers among D2D pairs to maximize the data rate. In this letter, we propose a distributed resource allocation to resolve these problems. Specifically, the interference from D2D transmissions to cellular users is coordinated using a pricing scheme, while a D2D pair competes with other pairs to efficiently reuse the available spectrum. We model this competition using a non-cooperative power control game and propose a distributed update rule to reach the Nash equilibrium. Simulation is provided to evaluate the performance of the proposed algorithm. |
