Resource Allocation for Device-to-Device Communication Underlaying Cellular Networks: An Alternating Optimization Method

In this letter, we study the resource allocation in cellular networks with device-to-device (D2D) communication enhancement, where multiple D2D pairs can share subchannels with cellular users (CUs). Our optimization task is to maximize the sum rate of the cellular system while satisfying the rate re...

Zusammenfassung:In this letter, we study the resource allocation in cellular networks with device-to-device (D2D) communication enhancement, where multiple D2D pairs can share subchannels with cellular users (CUs). Our optimization task is to maximize the sum rate of the cellular system while satisfying the rate requirements of all CUs. We propose an alternating optimization method to address the formulated problem efficiently. Numerical results show that our proposal can significantly increase the throughput of the cellular network.
