Abstract

To meet the immensely diverse service requirements, heterogeneous cloud radio access network (H-CRAN) architecture and D2D communication is embraced. Consequently, the resource allocation between D2D pairs and current users is a challenge. In this paper, a joint power control and sub-channel allocation scheme is proposed. The original mixed-integer nonlinear programming problem is decomposed into power and sub-channel allocation. Geometric Vertex Search approach and 3-dimensional (3-D) matching method are used to solve them. Finally, numerical results verify the proposed scheme has about 35% and 60% improvement in total throughput comparing with other approaches.

H-CRAN网络中基于三维匹配的D2D通信资源分配

为了满足多样化的业务需求，异构云无线接入网(H-CRAN)架构和D2D通信被采用。因此，D2D对和当前用户之间的资源分配是一个挑战。本文提出了一种联合功率控制和子信道分配方案。将原混合整数非线性规划问题分解为功率分配和子信道分配。采用几何顶点搜索法和三维匹配法进行求解。最后，数值计算结果表明，与其他方法相比，该方案的总吞吐量提高了35%和60%。
