论文摘要
本文研究了无线供电的无单元系统，在该系统中，用户通过执行自我能源回收利用，同时从网络节点和用户终端收集网络节点和用户终端（包括传输用户终端本身）的同时收集能量。在这种相当通用的环境中，得出了收获能量量的封闭形式的下限，并得出了所达到的信噪比 - 噪声比率表达式。然后，为了提高能源效率，我们制定了最大程度地减少用户电池能量使用的问题，同时满足最低数据速率要求。由于问题的非跨性别性，提出了一种新颖的交替优化算法，并提供了其收敛的证明。最后，数值结果表明，就电池能量使用和中断率而言，所提出的方法比最先进的算法更有效。
This paper investigates wireless-powered cell-free systems, in which the users send their uplink data signal while simultaneously harvesting energy from network nodes and user terminals - including the transmitting user terminal itself - by performing self-energy recycling. In this rather general setting, a closed-form lower bound of the amount of harvested energy and the achieved signal-to-interference-plus-noise ratio expressions are derived. Then, to improve the energy efficiency, we formulate the problem of minimizing the users' battery energy usage while satisfying minimum data rate requirements. Due to the non-convexity of the problem, a novel alternating optimization algorithm is proposed, and its proof of convergence is provided. Finally, numerical results show that the proposed method is more efficient than a state-of-art algorithm in terms of battery energy usage and outage rate.
