  Full-duplex (FD) communication is an emerging technology that can potentially
double the throughput of cellular networks. Preliminary studies in single-cell
or small FD network deployments have revealed promising rate gains using
self-interference cancellation (SIC) techniques and receive processing.
Nevertheless, the system-level performance gains of FD small cells in
ultra-dense networks (UDNs) have not been fully investigated yet. In this
paper, we evaluate the performance of resource allocation in ultra-dense FD
small-cell networks using spatial stochastic models for the network layout and
3GPP channel models. More specifically, we consider various UDN scenarios and
assess the performance of different low-complexity user-scheduling schemes and
power allocation between uplink and downlink. We also provide useful insights
into the effect of the SIC capability on the network throughput.
