A multiuser full‐duplex (FD) two‐wayrelaying system is considered with decode‐and‐forward relaying protocol. All nodes are assumed to have FD abilities, and residual self‐interference (RSI) at each node is modeled as a Rician‐distributed random variable. Based on the availability of channel state information (CSI) at the relay node, different scheduling schemes are adopted and investigated in terms of outage probability. For the blind case when CSI is unavailable, the random scheduling is analyzed. In the presence of CSI, the absolute channel power‐based scheduling and normalized channel power‐based scheduling schemes are considered. A precise closed‐form expression for the outage probability is derived for independent and nonidentically distributed channels. The theoretical results are verified through Monte Carlo simulations.
