Mm-Wave communication ushers next-gen communication to new heights guaranteeing higher speed and throughput. Enabling device-to-device (D2D) communication in next-gen wireless communication is a Herculean task. This is due to introduction of pathloss attenuation by various environmental factors which deteriorates the signal. This article aims to minimize the effect of interference for quality reception of signals for D2D communication and increase system throughput. Thus, a power control scheme is proposed in underlay mode for uplink channel in mm-Wave band. Here, D2D communication takes place through two modes namely, general mode and mm-Wave mode. In presence of large number of proximity D2D users and increasing pathloss attenuation, it switches to mm-Wave mode for communication. The formulated problem is converted to semiconvex form by expressing it into exponential form in Laplace domain. Our final objective is to maximize the energy efficiency (EE) of the proposed system under certain constraints. To reduce complexity of the problem, feasible regions of transmission power is introduced, that is, least and upper bounds which will ensure that power is maintained within a limit guaranteeing better throughput for D2D users. Enhanced EE and outage probability values also depict better performance of proposed system. Finally, fairness index (FI) shows that the proposed scheme yields better performance for the D2D users to communicate in the mm-Wave band. A detailed comparison of FI for the proposed scheme is also done with other existing methods to prove the adequate performance of the proposed method. Simulation results also prove the efficacy of the proposed scheme.

5G 毫米波网络中使用上行信道的设备到设备通信的功率控制方案

毫米波通信将下一代通信推向新高度，确保更高的速度和吞吐量。在下一代无线通信中启用设备到设备 (D2D) 通信是一项艰巨的任务。这是由于各种环境因素引入的路径损耗衰减导致信号恶化。本文旨在尽量减少干扰对 D2D 通信信号质量接收的影响，并提高系统吞吐量。因此，针对毫米波频段的上行链路信道，提出了一种底层模式的功率控制方案。在这里，D2D 通信通过两种模式进行，即普通模式和毫米波模式。在存在大量邻近 D2D 用户和增加路径损耗衰减的情况下，它会切换到毫米波模式进行通信。通过将公式化问题在拉普拉斯域中表达为指数形式，将其转换为半凸形式。我们的最终目标是在一定的约束条件下最大限度地提高拟议系统的能源效率（EE）。为了降低问题的复杂性，引入了传输功率的可行区域，即最小和上限，这将确保功率保持在保证D2D用户更好吞吐量的限制内。增强的 EE 和中断概率值也描述了建议系统的更好性能。最后，公平指数 (FI) 表明，所提出的方案为 D2D 用户在毫米波频段通信提供了更好的性能。还对所提出方案的 FI 进行了详细比较，并与其他现有方法进行了比较，以证明所提出方法的足够性能。
