面向大规模机器类型通信(MMTC)应用的设备到设备(D2D)通信是降低位于低覆盖区域的电池有限的机器类型设备(MTDS)能量消耗的一种很有前途的方法。本文分析了采用自动重传请求(ARQ)和混合ARQ与Chase合并(CC-HARQ)机制来提高D2D通信可靠性时MTDS的能量消耗。利用随机几何的工具，我们推导出了全局成功概率、平均传输次数和平均MTD能量消耗的解析表达式。数值结果表明，CC-HARQ在能量消耗方面优于ARQ，特别是当MTD与其中继之间的距离增加或共享同一子信道的MTDS密度增加时，尤其是在低中继密度的情况下。
Device-to-Device (D2D) communication for Massive Machine-Type Communication (mMTC) applications is a promising approach to reduce the energy consumption of the battery-limited Machine-Type Devices (MTDs) located in poor coverage areas. In this paper, we analyze the energy consumption of the MTDs when Automatic Repeat reQuest (ARQ) and Hybrid ARQ with Chase Combining (CC-HARQ) mechanisms are used to improve the reliability of D2D communications. By using the tools of stochastic geometry, we derive analytical expressions for the global success probability, the average number of transmissions, and the average MTD energy consumption. Numerical results show that CC-HARQ outperforms ARQ in terms of energy consumption, especially for low relay density when the distance between an MTD and its relay increases or when the density of MTDs sharing the same sub-channel increases.
