Abstract

The deployment of smallcell eNodeBs (SeNBs), overlaid on existing macrocell eNodeB (MeNB) is widely accepted as a key solution for improving spectral efficiency (SE). However, both SeNB and MeNB may suffer significant performance degradation due to inter/intra-tier interference. Meanwhile, the energy efficiency (EE) is another promising requirement especially when SeNB/MeNB are densely deployed. In this paper, a utility function with an α-adjustable parameter is proposed to achieve an optimal tradeoff between EE and SE. Then, an energy-aware capacity offload between the MeNB and multiple SeNBs is formulated as a Nash bargaining game, which is significantly simplified during the following analysis. To attain a win-win optimality for both the relatively involved SeNBs and MeNB, an energy-aware trigger of source-MeNB, interference-related right selected target-SeNB, and mutual interference compensation are all provided in this paper, which help to attain more dimensions of diversities and gains. Finally, simulation results show the improved performance of our proposed scheme.

具有干扰补偿的节能容量卸载到小基站

在现有的宏小区eNodeB (MeNB)上叠加部署小小区eNodeB (senb)被广泛认为是提高频谱效率(SE)的关键解决方案。然而，由于层间/层内干扰，SeNB和MeNB都可能遭受显著的性能下降。同时，能源效率(EE)是另一个有前景的需求，特别是在SeNB/MeNB密集部署时。本文提出了一个具有α-可调参数的效用函数，以实现EE和SE之间的最优权衡。然后，将MeNB和多个senb之间的能量感知容量卸载表述为纳什议价博弈，并在后续分析中进行了显著简化。为了实现相对相关的senb和MeNB的双赢最优，本文提供了源-MeNB的能量感知触发器、与干扰相关的权利选择目标- senb以及相互干扰补偿，有助于获得更多维度的多样性和增益。最后，仿真结果表明了所提方案的改进性能。
