| Abstract(in English) | The wireless communications network needs to be designed to support the traffic load that dynamically fluctuates over time. Thus, radio resources are underutilized at each base station (BS) during non-peak hour. This results in low energy efficiency. textit{BS sleep technology} has been considered as a promising approach to reduce the network energy consumption. However, from the view point of user equipment (UE), it may incur additional power as UE needs to transmit the uplink signal to BS which is located further. In this paper, the impact of BS sleep technology on the uplink energy consumption of UE is evaluated by computer simualation. Each BS is assumed to independetly switch between active mode and sleep mode according to a predetermined probability. Numerical results demonstrate that the energy consumption of UE highly depends on not only the sleep probability of BS but also the packet arrival intensity. |
