Reducing the energy consumption is one of the most demanding design targets for mobile devices. To this end, we develop a 3GPP-LTE cross-layer design that combines the functionality of Media Access Control (MAC) and Physical (PHY) layers with the power consumption of the hardware platform components to achieve an optimized solution in terms of energy consumption. Models for the baseband, the hardware,...
The success of dynamic spectrum access through simple listen-before-talk etiquettes has made way for opening up the spectrum. However, many problems still remain in this kind of networks. Stations might not be able to sense as much transmissions and hence defer channel access less often than their neighbors. This can lead to unfairness or (worst-case) starvation of certain terminals. In this paper...
