  In this paper, we provide a theoretical framework for the study of massive
multiple-input multiple-output (MIMO)-enabled full-duplex (FD) cellular
networks in which the self-interference (SI) channels follow the Rician
distribution and other channels are Rayleigh distributed. To facilitate
bi-directional wireless functionality, we adopt (i) a downlink (DL) linear
zero-forcing with self-interference-nulling (ZF-SIN) precoding scheme at the FD
base stations (BSs), and (ii) an uplink (UL) self-interference-aware (SIA)
fractional power control mechanism at the FD user equipments (UEs). Linear ZF
receivers are further utilized for signal detection in the UL. The results
indicate that the UL rate bottleneck in the baseline FD single-antenna system
can be overcome via exploiting massive MIMO. On the other hand, the findings
may be viewed as a reality-check, since we show that, under state-of-the-art
system parameters, the spectral efficiency (SE) gain of FD massive MIMO over
its half-duplex (HD) counterpart largely depends on the SI cancellation
capability of the UEs. In addition, the anticipated two-fold increase in SE is
shown to be only achievable with an infinitely large number of antennas.
