This paper considers a buffer-aided full-duplex (FD) relaying network assuming imperfect self-interference (SI) cancellation. The residual SI level is modeled to be proportional to the relay transmit power. Moreover, for quality-of-service (QoS) provisioning, the end-to-end queue-length is statistically constrained in terms of maximum acceptable outage probability. We derive the optimal power allocation solution for the source and relay to maximize the constant supportable arrival rate μ to the source (i.e., the effective capacity) and study its properties. Illustrative examples are performed to compare the effective capacities of the proposed FD relaying scheme and other benchmark schemes under different settings and QoS constraints.
