论文摘要
在本文中，我们提出了一种分布式功率控制算法，用于解决全球能源效率（GEE）最大化问题，以满足无线蜂窝网络中所有用户设备（UES）的最低目标SINR。我们将问题表示为一个多目标优化问题，该问题的目标是最大程度地减少总功耗并同时最大化总吞吐量，而所有UES都保证了最低目标SINR。我们建议在UES中执行的迭代方案，以使用单个通道状态信息（CSI）来控制其发射功率，以便以分布式方式最大化GEE。我们证明了所提出的迭代算法与其相应的唯一固定点的收敛性，我们的数值结果也显示了。此外，仿真结果表明，我们提出的方案优于文献中的其他算法，并且像在基站中执行的集中算法一样执行，并使用全局CSI最大化GEE。
In this paper, we propose a distributed power control algorithm for addressing the global energy efficiency (GEE) maximization problem subject to satisfying a minimum target SINR for all user equipments (UEs) in wireless cellular networks. We state the problem as a multi-objective optimization problem which targets minimizing total power consumption and maximizing total throughput, simultaneously, while a minimum target SINR is guaranteed for all UEs. We propose an iterative scheme executed in the UEs to control their transmit power using individual channel state information (CSI) such that the GEE is maximized in a distributed manner. We prove the convergence of the proposed iterative algorithm to its corresponding unique fixed point also shown by our numerical results. Additionally, simulation results demonstrate that our proposed scheme outperforms other algorithms in the literature and performs like the centralized algorithm executed in the base station and maximizes the GEE using the global CSI.
