摘　　要：为提高频谱资源利用率和系统吞吐量,提出一种基于超图的D2D资源分配方案。在保证蜂窝用户服务质量的同时,使一个蜂窝用户的频谱资源可以分配给多个D2D用户,尽可能地提高系统频谱资源的利用率;使用一种二阶段资源分配方案,允许一个D2D用户占用多个蜂窝用户的频谱资源。仿真结果表明,该方案能提高系统的总吞吐量,在保证蜂窝用户服务质量的同时,使单个D2D用户达到更高的吞吐率。To improve the utilization of spectrum resources and system throughput,a hypergraph based resource allocation scheme was proposed.The quality of the service of the cellular users was guaranteed,simultaneously the resources of a cellular user could be allocated to multiple D2D users,and the utilization rate of spectrum resources was improved as much as possible.A two-stage resource allocation scheme was used to allow a D2D user to reuse multiple spectrum resources.Simulation results show that the proposed scheme not only improves the system throughput,but also ensures the quality of the service of the cellular users,and a single D2D user can achieve higher performance.
