Full-duplex (FD) systems ideally double the system capacity compared to conventional half-duplex (HD) systems. However, we can obtain that goal only when FD systems always have both downlink (DL) and uplink (UL) traffic loads. This paper sheds new light on whether FD can achieve this promising performance enhancement in more realistic traffic settings. We first provide the sum capacity of the FD system when DL and UL traffic loads are different. In addition, we define the FD gain according to traffic loads and compare FD performance with the HD system which is based on time-division duplex (TDD). We then analyze the effect of traffic loads and residual self- interference (SI) on the FD system. Simulation results and analysis reveal that FD performance decreases in a limited traffic setting.
