Cooperative communication is an effective approach\ud for increasing the spectral efficiency and/or the coverage of cellular\ud networks as well as reducing the cost of network deployment.\ud However, it remains to be seen how energy efficient it is. In this\ud paper, we assess the energy efficiency of the conventional Amplifyand-forward\ud (AF) scheme in an in-building relaying scenario.\ud This scenario simplifies the mutual information formulation of\ud the AF system and allows us to express its channel capacity with\ud a simple and accurate closed-form approximation. In addition,\ud a framework for the energy efficiency analysis of AF system\ud is introduced, which includes a power consumption model and\ud an energy efficiency metric, i.e. the bit-per-joule capacity. This\ud framework along with our closed-form approximation are utilized\ud for assessing both the channel and bit-per-joule capacities of\ud the AF system in an in-building scenario. Our results indicate\ud that transmitting with maximum power is not energy efficient\ud and that AF system is more energy efficient than point-to-point\ud communication at low transmit powers and signal-to-noise ratios.
