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.
