In this paper, we discuss physical-layer network coding (PLNC) in the two-way decode-forward (DF) relay to obtain total minimum power consumption (MPC) for the entire transmission process. The MPC and power allocation scheme for each node are obtained under a predetermined constraint of outage probability threshold in a Rayleigh fading channel environment. Numerical experimental results confirm that the proposed MPC scheme achieves much lower power consumption ratio than the existing schemes without PLNC on the condition of the same system outage guarantee.
