摘　　要：设备到设备(D2D)通信中,不合理的模式选择和信道分配方案会引入干扰,严重时不仅不能体现D2D通信优势,而且还将导致蜂窝用户传输速率下降。针对这一问题,文章提出了一种蜂窝网络中D2D模式选择和信道分配算法。仿真结果表明,新算法能够在有效的平衡蜂窝网络中D2D用户接入率和系统总吞吐量的同时,最小化用户之间的干扰。In Device-to-Device(D2D)communication,improper mode selection and channel allocation schemes introduce interference,which in severe cases not only does not reflect the D2Dcommunication advantages,but also causes the cellular user transmission rate to drop.To solve this problem,this paper proposes a D2D mode selection and channel allocation algorithmin cellular networks.The simulation results show that the new algorithmcan minimize the interference between users while effectively balancing the D2D user access rate and total systemthroughput in the cellular network.
