蜂窝网络中的D2D(device-to-device,终端直通)技术可以提高频谱资源利用率和用户的吞吐量,然而, D2D通信会对蜂窝用户和其他D2D用户产生干扰,合适的模式选择与资源分配方案就变得相当重要。研究了蜂窝用户和D2D用户的干扰情况,并提出了一种基于D2D位置的联合模式选择与资源分配方案,该方案根据D2D用户在小区中的位置和终端的干扰情况对D2D用户的通信模式和资源的复用方式进行了优化,从而提升系统下行链路的性能。仿真结果表明,相比于已有方案和纯蜂窝方案,采用基于位置的联合模式选择与资源分配方案能得到更高的系统吞吐量。
Device-to-device(D2D)communication underlaying cellular networks can bring great benefits to spectrum resource utilization and users' throughput. However
because of the interference caused by D2D communication
interference cancellation and coordination becomes very important. A joint mode selection and resource allocation scheme was proposed to improve the performance of system in the downlink direction. Simulation results show that
compared to pure greed D2D scheme and cellular scheme
the proposed scheme can achieve higher system throughput.
