In this paper, we address the energy ef ciency analysis of
the relay channel under ergodic fading. The study considers
full duplex and half duplex terminals. Since the capacity of
general relay channels is unknown, we investigate achievable
rates with decode and forward and capacity upper bounds
with the cut-set bound. The maximum rate per energy and
the slope of the spectral ef ciency with the energy per bit are
computed to asses the impact of the duplexing capabilities,
the resource allocation and the channel fading distribution.
