    We present a new design concept for adaptive wireless communications with new trade-offs between system performance and energy consumption. The system performance, in terms of bit error rate, outage probability, and achieved spectral efficiency, depends on constellation signaling, applied diversity, and channel estimation. Resources dedicated to channel estimation and feedback traffic contribute t... View full abstract»

    Recent analysis by manufacturers and network operators has shown that current wireless networks are not very energy efficient, particularly the base stations by which terminals access services from the network. In response to this observation the Mobile Virtual Centre of Excellence (VCE) Green Radio project was established in 2009 to establish how significant energy savings may be obtained in futu...

    The operation of cellular network infrastructure incurs significant electrical energy consumption. From the perspective of cellular network operators, reducing this consumption is not only a matter of showing environmental responsibility, but also of substantially reducing their operational expenditure. We discuss how dynamic operation of cellular base stations, in which redundant base stations ar... View full abstract»

    Energy consumption is becoming an increasingly important issue throughout the community. For network operators in particular it is a concern as networks expand to deliver increasing traffic levels to increasing numbers of customers. The majority of the energy used by the Internet today is consumed in the access network, and this will continue to be the case for the short-to-mid- term future. Acces... View full abstract»

    Reducing energy consumption in the Internet has become an increasingly important goal recently. Previous work on reducing energy consumption has primarily looked at either changing link rates or putting interfaces to sleep. Due to the unpredictable nature of traffic, the energy savings achieved have been modest, do not scale, and incur losses and delay. This article proposes a different approach t...

    A great deal of research has contributed to the energy efficiency of battery-operated devices in the area of wireless communications, but recently, the energy consumption of the underlying network infrastructure has started to attract more attention as people have become aware of the significant fraction of energy consumed by the Internet of all the energy we consume. We argue that the architectur... View full abstract»

    Carrier aggregation is one of the key features for LTE-Advanced. By means of CA, users gain access to a total bandwidth of up to 100 MHz in order to meet the IMT-Advanced requirements. The system bandwidth may be contiguous, or composed of several non-contiguous bandwidth chunks that are aggregated. This article presents a summary of the supported CA scenarios as well as an overview of the CA func... View full abstract»
