| Outline of Final Research Achievements |
This research investigates the wireless system configuration technique for heterogeneous cellular network, which is a hierarchized cellular network overlaying small base station layer on top of macro base station layer. This research proposes energy saving mechanism (sleep control mechanism), which achieves both a reduction of power consumption at the small base stations and better provision of quality of services (QoS) to user equipments (UEs) .
Through the performance evaluation by computer simulation, this research demonstrates the proposed energy saving mechanism (sleep control mechanism) improves the system performance, such as power consumption and energy efficiency in the network, and also QoS satisfaction rate at UEs.
