Performance Analysis for Full-Duplex Networks with Interference Cancellation and Retransmission

This paper investigates the full-duplex (FD) stochastic networks with interference cancellation (IC) and packet retransmission. To distinguish strong and weak interference, we use the concept of strong interference region, and an interference cancellation scheme is adopted to eliminate the uplink (UL) interference from the strong interference region. Moreover, instead of discarding the unsatisfied UL/downlink (DL) request, the packet retransmission mechanism is considered to ensure successful packet transmission, wherein the user's request will remain in the UL/DL buffer head until it is satisfied. That brings the coupled relationship between the UL/DL outage probabilities and buffer empty probabilities. To better analyze the combined impact of IC operation and retransmission in FD networks, we derive the outage probability and the proportions of BSs working in different modes. The simulation results show that in a stochastic FD network with retransmission, IC operation at the DL users not only significantly decreases the DL transmission outage probability but also decreases that of the UL transmission.
