چکیده
In this study, an energy-efficient self-organized framework for sub-channel allocation and power is presented ultra-dense small cell networks, which can operate in both licensed unlicensed bands. order to protect legacy WiFi devices (operating bands), we consider the Long-Term Evolution (LTE) operation bands based on Carrier Sense Adaptive Transmission (CSAT), 'ON' 'OFF' duty cycle approach utilized. On other hand, there are severe interference management problems among cells bands) between macro due co-channel deployment of cells. This article proposes a optimization sub-channels levels by exploiting non-cooperative game with objective maximize energy efficiency dual-access without creating harmful impact coexisting network entities including users, devices. Simulation results show that proposed scheme outperforms (6 11 percent) (8 18 round-robin spectrum-efficient schemes, respectively, two different scenarios. addition, it shown less channel state information (CSI) estimation errors ς = 0.02, maximum performance degradation reasonably (5.5 as compared perfect CSI.
