PROJECT TITLE :
Energy-Efficient Transmissions for Green Base Stations With a Novel Carrier Activation Algorithm: A System-Level Perspective
A base station (BS) that allows multiple component carriers (CCs) to be jointly utilised for data transmissions is one of the most advanced cellular systems. This kind of BS aims to deal with the amazingly quick-growing demand from varied users. However, such a BS is the most energy-intensive half of a cellular network because the activation of its additional CCs consumes a massive amount of energy, which, in flip, causes environmental problems and higher prices for cellular operators. Consequently, a way to efficiently save energy when employing a multi-CC BS is an increasingly critical concern within the deployment of inexperienced cellular networks. This paper builds a practical framework for studying energy-efficient transmissions for a multi-CC BS from a system-level perspective involving both radio resource allocation and CC activation/deactivation, whereas additionally presenting several new transmission schemes for use in the multi-CC BS. In these schemes, a unique energy-saving algorithm for activating/deactivating CCs is combined with different radio resource allocation approaches, respectively. Simulation results demonstrate that these schemes have a lot of higher energy-saving performance than that of the standard one. Furthermore, comparisons among the presented schemes are detailed.
