As a new energy saving approach for green communications, energy harvesting (EH) could be suitable technique to facilitate massive connections for large number of devices in such networks. The spectrum shortage occurs in huge number of devices which access with small-cell and macro-cell networks. To tackle these challenges, we develop a tractable framework relying on prominent techniques such as non-orthogonal multiple access (NOMA), antenna selection and energy harvesting. In this paper, we aim at practical scenarios of small cell networks by jointly evaluating capable of interference management and EH. We benefit from transmission approaches including full duplex (FD) and bi-directional transmission to improve the main performance system metrics such as outage probability and throughput. Three useful schemes are explored by considering EH and inter-cell interference. We derive the closed-form and asymptotic expressions for system metrics. We then perform extensive simulations with different system configurations to confirm the effectiveness of the proposed small-cell NOMA systems.

利用天线选择和能量收集对大规模网络连接的影响

作为绿色通信的一种新的节能方法，能量收集 (EH) 可能是促进此类网络中大量设备的大规模连接的合适技术。大量接入小蜂窝和宏蜂窝网络的设备会出现频谱短缺。为了应对这些挑战，我们开发了一个易于处理的框架，该框架依赖于非正交多址 (NOMA)、天线选择和能量收集等突出技术。在本文中，我们通过联合评估干扰管理和 EH 的能力，针对小型小区网络的实际场景。我们受益于包括全双工 (FD) 和双向传输在内的传输方法，以提高主要性能系统指标，例如中断概率和吞吐量。通过考虑 EH 和小区间干扰，探索了三种有用的方案。我们推导出系统度量的封闭形式和渐近表达式。然后，我们使用不同的系统配置进行广泛的模拟，以确认所提出的小蜂窝 NOMA 系统的有效性。
