论文摘要
本文研究了设备对设备（D2D）通信的能源效率最大化，该通信是毫米波（MM-WAVE）频段中细胞网络的底层底层。随机几何框架已用于提取结果。首先，细胞和D2D用户是由独立的均匀泊松点过程建模的。然后，已得出了成功传输概率和蜂窝用户的精确表达式。此外，已经提出了典型D2D场景的平均总和率和能源效率。已经定义了蜂窝和D2D用户的传输功率和服务限制质量的优化问题，并且最大化D2D通信的能源效率。仿真结果表明，通过在毫米波中工作，可以实现显着的能源效率提高，例如，与瑞利分布相比，在实际情况下，通过考虑电路功率而提高了20 \％的能源效率。最后，为了验证我们的分析表达式，进行了模拟研究，并达成了出色的协议。
This paper studies energy efficiency maximization in device-to-device (D2D) communications underlaying cellular networks in millimeter-wave (mm-wave) band. A stochastic geometry framework has been used to extract the results. First, cellular and D2D users are modeled by independent homogeneous Poisson point process; then, exact expressions for successful transmission probability of D2D and cellular users have been derived. Furthermore, the average sum rate and energy efficiency for a typical D2D scenario have been presented. An optimization problem subject to transmission power and quality of service constraints for both cellular and D2D users has been defined and energy efficiency of D2D communication is maximized. Simulation results reveal that by working in millimeter-wave, significant energy efficiency improvement can be attained, e.g., 20\% energy efficiency improvement compared to Rayleigh distribution in the practical scenarios by considering circuit power. Finally, to verify our analytical expressions, the simulation studies are carried out and the excellent agreements have been achieved.
