摘要：
In cellular networks with D2D systems, high energy cost and interference between cellular users and D2D users become critical and need to be properly handled. In this paper, we present a hybrid-duplex system model where D2D users can switch the duplex mode between half-duplex and full-duplex. Then a resource allocation scheme based on multi-element joint optimization is proposed. The algorithm first guarantees the quality of service (QoS) of cellular users and then maximizes the system capacity through the joint optimal allocation of the user's access control, power allocation, duplex mode selection and channel allocation. Simulation results show that the proposed scheme can improve the overall performance of the networks greatly. © 2020, Jilin University Press. All right reserved.
