In this paper, we investigate energy efficiency (EE) of co-located antenna system (CAS) and the distributed antenna system (DAS) with and without device-to-device (D2D) communications, respectively. We derive an approximate EE expression for both the idealistic and the realistic power consumption models in CAS and DAS with D2D communication. Numerical results show that the D2D communication is exactly benefited to improve the EE, especially in the DAS.
