摘　　要：针对在5G通信网络中,联合资源分配方式下的D2D(Device-to-Device)通信模式选择问题,提出了利用启发式算法代替匈牙利算法对D2D的模式选择进行优化的通信模型;本算法在保证了D2D通信对尽可能多接入的同时,最大化系统总吞吐量。分析结果说明,此算法能显著优化系统总吞吐量,减少用户之间的通信干扰,证明了该通信模型的合理性和高效性。Specific to the maximization ol the system throughput,the joint resource al location schemes lor device-to-device （D2D） communication are proposed. Another purpose of the joint resource allocation schemes is to avoid the strong interference between cellular communication and the D2D communication. The core strategy of the algorithm is to establish a throughput matrix and find maximum throughput according to the D2D and cellular users. The results show that the proposed methods significantly improve the system throughput and the number of permitted D2D users.
