Abstract :
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, and the MAC are merged such that tuning their parameters leads to an optimal solution for a given path loss and data rate. Energy gains larger than 50% are obtained with this approach compared to two state-of-the-art approaches.
