说明：  设备到设备(Device-to-device, D2D)通信是一种很有前途的提高蜂窝网络频谱效率的技术 网络。 在本文中，我们研究了联合上行链路和 下行资源分配问题的总和最大化 在保证服务质量的同时保证系统的数据速率 (QoS)蜂窝用户设备(CUEs)和D2D用户 设备(费)。
(Device-to-device (D2D) communication is a promising technology to improve the spectral efficiency of cellular networks. In this paper, we investigate the joint uplink and downlink resource allocation problem to maximize the sum data rate of the system while guaranting the quality of service (QoS) for both cellular user equipments (CUEs) and D2D user equipments (DUEs).)
