Title
Energy efficient beamforming transmission scheme considering hourly users' distribution.
Abstract
A lot of telecommunication infrastructures have been built to cope with the rapid growth of smartphone users. As time goes by, natural resources start to deplete and electricity expenditure becomes expensive. This has raised the problem of power consumption in the cellular base station. Therefore, energy efficient base stations are required to overcome the difficulties. In this paper, a beamforming transmission scheme with low power consumption in the base station is proposed considering the hourly users' distribution. The downlink directional signal transmission occurs to the places where there is a high userdensity area. When users are equally distributed, the base station keeps its omni- directional transmission manner. The proposed beamforming transmission scheme is evaluated in terms of the hourly total power consumption in the base station comparing with the conventional omni- directional transmission. In addition, the uncovered user ratio to all the users in the cell is discussed to verify the effectiveness of the proposed scheme.
