N2 - 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.
