A simple power-saving transmission scheme for use in macrocell-small cell networks

Abstract

Among researchers seeking to enhance the network coverage of macrocells, the utilization of small cell base stations (SBSs) is regarded as an approach with considerable promise. In the present study, we present a straightforward yet robust power-saving transmission scheme for use in macrocellsmall cell networks. The scheme presented herein both allows an SBS to be activated or deactivated in an efficient manner in response to the traffic load and closes any coverage holes (i.e., areas where users are unable to get a signal from the wireless network) by smartly enlarging neighboring small cells as needed when users attempt to use the network. At the same time, the scheme also allows pre-determined data rate requirements to be maintained. Data from simulations utilizing the proposed scheme indicate that it provides far greater energy savings than the conventional scheme.
