The feasible power region for co‐channel uplink and downlink users without channel state information is investigated in full‐duplex (FD) communications. A closed‐form expression for minimising the overall transmit power is derived in the high signal‐to‐noise case. It has been shown that FD has a better power efficiency than the traditional half‐duplex communication when the residual self‐interference is weak or the users are located near the base station.
