基于CoMP传输的分布式异构网络资源分配

摘要：提高无线资源利用效率是缓解日益增长的无线通信需求和有限的可用传输资源之间矛盾的主要途径。基于多点协调（coordinated multipoint,CoMP）传输技术的异构网络在提高频谱效率和能量效率方面具有巨大的潜力，近年来受到学术界和工业界的广泛关注。在研究基于CoMP技术的异构网络资源分配问题的基础上，提出了一种基于交叉熵方法的分布式频谱资源调度算法。仿真实验验证了本文提出方法在系统吞吐量、能量效率以及用户公平性等方面的有效性。

Resource Allocation of Distributed Heterogeneous Network Based on CoMP Transmission

Improving utilization of radio resource is a promising solution to alleviate the contradiction between increasing wireless communications demands and limited radio resources of wireless transmission. Coordinated multipoint （CoMP）based heterogeneous network （HetNet）has huge application prospects to improve the spectrum efficiency and energy efficiency, and therefore, has attracted constant attentions from not only academia and industry. The radio resource allocation for CoMP based HetNet was investigated, and a distributed resource schedule algorithm by means of cross-entropy method was proposed. Extensive simulations are conducted to verify the effectiveness of the proposed algorithm in terms of throughput, energy efficiency and user fairness.
