D2D通信资源调度研究现状综述

Review of Research on Resource Scheduling of D2D Communication

终端直通技术(D2D)是一种终端在基站控制下直接进行通信而不需要基站转发的新型通信技术。D2D引入LTE-A蜂窝系统虽然可以带来吞吐量和频谱效率的提升,但是也会带来很大的干扰。综合近些年来的研究成果,合理的资源调度算法成为降低干扰、提升系统性能的关键。首先,描述了D2D通信技术引入LTE-A蜂窝网络后的系统干扰模型。然后,从模式选择、资源分配和功率控制3个方面综述了目前国内外文献关于资源调度算法的研究成果。

Device-to-Device（D2D） is a new communication technology which is directly communicating with each other by using user equipment under the control of the base station. Although the introduction of D2D communication into cellular system can im- prove the throughput and the efficiency of the spectrmn, it also brings interference. Combined with the research achievements in re- cent years, reasonable resource scheduling algorithm is the key to reduce the interference and improve the system performance. First of all, the system interference model of LTE-A cellular network within D2D communication is analyzed. Finally, the research results of the resource scheduling algorithms is summarized from three aspects such as mode selection, resource allocation and power control.
