Abstract

Full duplex heterogeneous networks are considered as a mean of boosting the performance of future wireless communication networks. In this paper, we study full duplex orthogonal division multiple access (OFDMA) heterogeneous network. In our model, each node will operate either in full duplex or half duplex multiuser MIMO. In addition, each user will attempt to connect to the macro base station or one of the available small cell access points. Moreover, it is assumed that there exist strict transmission power constraints on each transmitting node and each user. Accordingly, a joint resource allocation problem which maximizes the aggregate network's throughput by considering mode selection, user pairing, subcarrier allocation and power control is proposed. Additionally, the performance of our proposed scheme is evaluated indicating the effects of different system parameters on the system performance. Finally, our proposed scheme's performance is compared with that of a network which operates in full-duplex only or half-duplex only.

全双工OFDMA HetNets中的模式选择、用户配对、子载波分配和功率控制

全双工异构网络被认为是提高未来无线通信网络性能的一种手段。本文研究了全双工正交多址(OFDMA)异构网络。在我们的模型中，每个节点将以全双工或半双工多用户MIMO方式运行。此外，每个用户将尝试连接到宏基站或一个可用的小蜂窝接入点。并且，假设对每个传输节点和每个用户都存在严格的传输功率约束。在此基础上，提出了一种综合考虑模式选择、用户配对、子载波分配和功率控制，使聚合网络吞吐量最大化的联合资源分配问题。此外，我们提出的方案的性能进行了评估，表明不同的系统参数对系统性能的影响。最后，将所提方案的性能与全双工或半双工网络的性能进行了比较。
